| 18 | <H3>Release 3d (2017 August)</H3> | ||
| 19 | |||
| 20 | <UL> | ||
| 21 | |||
| 22 | <LI> | ||
| 23 | Fixed bugs in the square root functions for <NOBR>64-bit</NOBR> | ||
| 24 | double-precision, <NOBR>80-bit</NOBR> double-extended-precision, and | ||
| 25 | <NOBR>128-bit</NOBR> quadruple-precision. | ||
| 26 | For <NOBR>64-bit</NOBR> double-precision (<CODE>f64_sqrt</CODE>), the result | ||
| 27 | could sometimes be off by <NOBR>1 unit</NOBR> in the last place | ||
| 28 | (<NOBR>1 ulp</NOBR>) from what it should be. | ||
| 29 | For the larger formats, the square root could be wrong in a large portion of | ||
| 30 | the less-significant bits. | ||
| 31 | (A bug in <CODE>f128_sqrt</CODE> was first reported by Alexei Sibidanov.) | ||
| 32 | |||
| 33 | </UL> | ||
| 34 | |||
| 35 | |||
| 36 | <H3>Release 3c (2017 February)</H3> | ||
| 37 | |||
| 38 | <UL> | ||
| 39 | |||
| 40 | <LI> | ||
| 41 | Added optional rounding mode <CODE>odd</CODE> (round to odd, also known as | ||
| 42 | <EM>jamming</EM>). | ||
| 43 | |||
| 44 | <LI> | ||
| 45 | Corrected the documentation concerning non-canonical representations in | ||
| 46 | <NOBR>80-bit</NOBR> double-extended-precision. | ||
| 47 | |||
| 48 | </UL> | ||
| 49 | |||
| 50 | |||
| 51 | <H3>Release 3b (2016 July)</H3> | ||
| 52 | |||
| 53 | <UL> | ||
| 54 | |||
| 55 | <LI> | ||
| 56 | Implemented the common <NOBR>16-bit</NOBR> “half-precision” | ||
| 57 | floating-point format (<CODE>float16_t</CODE>). | ||
| 58 | |||
| 59 | <LI> | ||
| 60 | Made the integer values returned on invalid conversions to integer formats | ||
| 61 | be determined by the port-specific specialization instead of being the same for | ||

| 95 | Major changes included renaming most types and functions, upgrading some | ||
| 96 | algorithms, restructuring the source files, and making SoftFloat into a true | ||
| 97 | library. | ||
| 98 | |||
| 99 | <LI> | ||

| 150 | Added functions to convert between <NOBR>64-bit</NOBR> integers | ||
| 151 | (<CODE>int64</CODE>) and all supported floating-point formats. | ||
| 152 | |||
| 153 | <LI> | ||
| 154 | Fixed a bug in all <NOBR>64-bit</NOBR>-version square root functions except | ||
| 155 | <CODE>float32_sqrt</CODE> that caused the result sometimes to be off by | ||
| 156 | <NOBR>1 unit</NOBR> in the last place (<NOBR>1 ulp</NOBR>) from what it should | ||
| 157 | be. | ||
| 158 | (Bug discovered by Paul Donahue.) | ||

| 173 | <LI> | ||
| 174 | Changed the source directory structure, splitting the sources into a | ||
| 175 | <CODE>bits32</CODE> and a <CODE>bits64</CODE> version. | ||
| 176 | Renamed <CODE>environment.h</CODE> to <CODE>milieu.h</CODE> to avoid confusion | ||
| 177 | with environment variables. | ||
| 178 | |||
| 179 | <LI> | ||
| 180 | Fixed a small error that caused <CODE>float64_round_to_int</CODE> often to | ||
| 181 | round the wrong way in nearest/even mode when the operand was between | ||
| 182 | 2<SUP>20</SUP> and 2<SUP>21</SUP> and halfway between two integers. | ||

| 49 | <H2>1. Introduction</H2> | ||
| 50 | |||
| 51 | <P> | ||
| 52 | This document gives information needed for compiling and/or porting Berkeley | ||
| 53 | SoftFloat, a library of C functions implementing binary floating-point | ||
| 54 | conforming to the IEEE Standard for Floating-Point Arithmetic. | ||
| 55 | For basic documentation about SoftFloat refer to | ||
| 56 | <A HREF="SoftFloat.html"><NOBR><CODE>SoftFloat.html</CODE></NOBR></A>. | ||
| 57 | </P> | ||
| 58 | |||
| 59 | <P> | ||
| 60 | The source code for SoftFloat is intended to be relatively machine-independent | ||
| 61 | and should be compilable with any ISO-Standard C compiler that also supports | ||
| 62 | <NOBR>64-bit</NOBR> integers. | ||
| 63 | SoftFloat has been successfully compiled with the GNU C Compiler | ||
| 64 | (<CODE>gcc</CODE>) for several platforms. | ||
| 65 | </P> | ||
| 66 | |||
| 67 | <P> | ||
| 68 | <NOBR>Release 3</NOBR> of SoftFloat was a complete rewrite relative to | ||
| 69 | <NOBR>Release 2</NOBR> or earlier. | ||
| 70 | Changes to the interface of SoftFloat functions are documented in | ||
| 71 | <A HREF="SoftFloat.html"><NOBR><CODE>SoftFloat.html</CODE></NOBR></A>. | ||
| 72 | The current version of SoftFloat is <NOBR>Release 3d</NOBR>. | ||
| 73 | </P> | ||
| 74 | |||
| 75 | |||
| 76 | <H2>2. Limitations</H2> | ||
| 77 | |||
| 78 | <P> | ||
| 79 | SoftFloat assumes the computer has an addressable byte size of either 8 or | ||
| 80 | <NOBR>16 bits</NOBR>. | ||
| 81 | (Nearly all computers in use today have <NOBR>8-bit</NOBR> bytes.) | ||
| 82 | </P> | ||
| 83 | |||
| 84 | <P> | ||
| 85 | SoftFloat is written in C and is designed to work with other C code. | ||
| 86 | The C compiler used must conform at a minimum to the 1989 ANSI standard for the | ||
| 87 | C language (same as the 1990 ISO standard) and must in addition support basic | ||
| 88 | arithmetic on <NOBR>64-bit</NOBR> integers. | ||
| 89 | Earlier releases of SoftFloat included implementations of <NOBR>32-bit</NOBR> | ||
| 90 | single-precision and <NOBR>64-bit</NOBR> double-precision floating-point that | ||
| 91 | did not require <NOBR>64-bit</NOBR> integers, but this option is not supported | ||
| 92 | starting with <NOBR>Release 3</NOBR>. | ||
| 93 | Since 1999, ISO standards for C have mandated compiler support for | ||
| 94 | <NOBR>64-bit</NOBR> integers. | ||
| 95 | A compiler conforming to the 1999 C Standard or later is recommended but not | ||
| 96 | strictly required. | ||
| 97 | </P> | ||
| 98 | |||
| 99 | <P> | ||
| 100 | <NOBR>C Standard</NOBR> header files <CODE><stdbool.h></CODE> and | ||
| 101 | <CODE><stdint.h></CODE> are required for defining standard Boolean and | ||
| 102 | integer types. | ||
| 103 | If these headers are not supplied with the C compiler, minimal substitutes must | ||
| 104 | be provided. | ||
| 105 | SoftFloat’s dependence on these headers is detailed later in | ||
| 106 | <NOBR>section 5.1</NOBR>, <I>Standard Headers <CODE><stdbool.h></CODE> | ||
| 107 | and <CODE><stdint.h></CODE></I>. | ||

| 114 | The SoftFloat package was written by me, <NOBR>John R.</NOBR> Hauser. | ||
| 115 | <NOBR>Release 3</NOBR> of SoftFloat was a completely new implementation | ||
| 116 | supplanting earlier releases. | ||
| 117 | The project to create <NOBR>Release 3</NOBR> (now <NOBR>through 3d</NOBR>) was | ||
| 118 | done in the employ of the University of California, Berkeley, within the | ||
| 119 | Department of Electrical Engineering and Computer Sciences, first for the | ||
| 120 | Parallel Computing Laboratory (Par Lab) and then for the ASPIRE Lab. | ||
| 121 | The work was officially overseen by Prof. Krste Asanovic, with funding provided | ||
| 122 | by these sources: | ||

| 204 | <H2>4. SoftFloat Package Directory Structure</H2> | ||
| 205 | |||
| 206 | <P> | ||
| 207 | Because SoftFloat is targeted to multiple platforms, its source code is | ||
| 208 | slightly scattered between target-specific and target-independent directories | ||
| 209 | and files. | ||
| 210 | The supplied directory structure is as follows: | ||
| 211 | <BLOCKQUOTE> | ||
| 212 | <PRE> | ||
| 213 | doc | ||
| 214 | source | ||
| 215 | include | ||
| 216 | 8086 | ||
| 217 | 8086-SSE | ||
| 218 | build | ||
| 219 | template-FAST_INT64 | ||
| 220 | template-not-FAST_INT64 | ||

| 225 | Win32-SSE2-MinGW | ||
| 226 | Win64-MinGW-w64 | ||
| 227 | </PRE> | ||
| 228 | </BLOCKQUOTE> | ||
| 229 | The majority of the SoftFloat sources are provided in the <CODE>source</CODE> | ||
| 230 | directory. | ||
| 231 | The <CODE>include</CODE> subdirectory of <CODE>source</CODE> contains several | ||
| 232 | header files (unsurprisingly), while the <CODE>8086</CODE> and | ||
| 233 | <NOBR><CODE>8086-SSE</CODE></NOBR> subdirectories contain source files that | ||
| 234 | specialize the floating-point behavior to match the Intel x86 line of | ||
| 235 | processors. | ||
| 236 | The files in directory <CODE>8086</CODE> give floating-point behavior | ||
| 237 | consistent solely with Intel’s older, 8087-derived floating-point, while | ||
| 238 | those in <NOBR><CODE>8086-SSE</CODE></NOBR> update the behavior of the | ||
| 239 | non-extended formats (<CODE>float16_t</CODE>, <CODE>float32_t</CODE>, | ||
| 240 | <CODE>float64_t</CODE>, and <CODE>float128_t</CODE>) to mirror Intel’s | ||
| 241 | more recent Streaming SIMD Extensions (SSE) and other compatible extensions. | ||
| 242 | If other specializations are attempted, these would be expected to be other | ||
| 243 | subdirectories of <CODE>source</CODE> alongside <CODE>8086</CODE> and | ||
| 244 | <NOBR><CODE>8086-SSE</CODE></NOBR>. | ||
| 245 | Specialization is covered later, in <NOBR>section 5.2</NOBR>, <I>Specializing | ||
| 246 | Floating-Point Behavior</I>. | ||
| 247 | </P> | ||
| 248 | |||
| 249 | <P> | ||
| 250 | The <CODE>build</CODE> directory is intended to contain a subdirectory for each | ||
| 251 | target platform for which a build of the SoftFloat library may be created. | ||
| 252 | For each build target, the target’s subdirectory is where all derived | ||
| 253 | object files and the completed SoftFloat library (typically | ||
| 254 | <CODE>softfloat.a</CODE> or <CODE>libsoftfloat.a</CODE>) are created. | ||
| 255 | The two <CODE>template</CODE> subdirectories are not actual build targets but | ||
| 256 | contain sample files for creating new target directories. | ||
| 257 | (The meaning of <CODE>FAST_INT64</CODE> will be explained later.) | ||
| 258 | </P> | ||
| 259 | |||
| 260 | <P> | ||
| 261 | Ignoring the <CODE>template</CODE> directories, the supplied target directories | ||
| 262 | are intended to follow a naming system of | ||
| 263 | <NOBR><CODE><<I>execution-environment</I>>-<<I>compiler</I>></CODE></NOBR>. | ||
| 264 | For the example targets, | ||
| 265 | <NOBR><CODE><<I>execution-environment</I>></CODE></NOBR> is | ||
| 266 | <NOBR><CODE>Linux-386</CODE></NOBR>, <NOBR><CODE>Linux-386-SSE2</CODE></NOBR>, | ||
| 267 | <NOBR><CODE>Linux-x86_64</CODE></NOBR>, <CODE>Win32</CODE>, | ||
| 268 | <NOBR><CODE>Win32-SSE2</CODE></NOBR>, or <CODE>Win64</CODE>, and | ||
| 269 | <NOBR><CODE><<I>compiler</I>></CODE></NOBR> is <CODE>GCC</CODE>, | ||
| 270 | <CODE>MinGW</CODE>, or <NOBR><CODE>MinGW-w64</CODE></NOBR>. | ||
| 271 | </P> | ||
| 272 | |||
| 273 | <P> | ||
| 274 | At the current time, all of the supplied target directories are merely examples | ||
| 275 | that may or may not be correct for compiling on any particular system. | ||
| 276 | Despite requests, there are currently no plans to include and maintain in the | ||
| 277 | SoftFloat package the build files needed for a great many users’ | ||
| 278 | compilation environments, which after all can span a broad range of operating | ||
| 279 | systems, compilers, and other tools. | ||
| 280 | </P> | ||
| 281 | |||
| 282 | <P> | ||
| 283 | As supplied, each target directory contains two files: | ||
| 284 | <BLOCKQUOTE> | ||
| 285 | <PRE> | ||
| 286 | Makefile | ||
| 287 | platform.h | ||
| 288 | </PRE> | ||
| 289 | </BLOCKQUOTE> | ||
| 290 | The provided <CODE>Makefile</CODE> is written for GNU <CODE>make</CODE>. | ||
| 291 | A build of SoftFloat for the specific target is begun by executing the | ||
| 292 | <CODE>make</CODE> command with the target directory as the current directory. | ||
| 293 | A completely different build tool can be used if an appropriate | ||
| 294 | <CODE>Makefile</CODE> equivalent is created. | ||
| 295 | </P> | ||
| 296 | |||
| 297 | <P> | ||
| 298 | The <CODE>platform.h</CODE> header file exists to provide a location for | ||
| 299 | additional C declarations specific to the build target. | ||
| 300 | Every C source file of SoftFloat contains a <CODE>#include</CODE> for | ||
| 301 | <CODE>platform.h</CODE>. | ||
| 302 | In many cases, the contents of <CODE>platform.h</CODE> can be as simple as one | ||
| 303 | or two lines of code. | ||
| 304 | At the other extreme, to get maximal performance from SoftFloat, it may be | ||
| 305 | desirable to include in header <CODE>platform.h</CODE> (directly or via | ||
| 306 | <CODE>#include</CODE>) declarations for numerous target-specific optimizations. | ||
| 307 | Such possibilities are discussed in the next section, <I>Issues for Porting | ||
| 308 | SoftFloat to a New Target</I>. | ||
| 309 | If the target’s compiler or library has bugs or other shortcomings, | ||
| 310 | workarounds for these issues may also be possible with target-specific | ||
| 311 | declarations in <CODE>platform.h</CODE>, avoiding the need to modify the main | ||
| 312 | SoftFloat sources. | ||

| 319 | |||
| 320 | <P> | ||
| 321 | The SoftFloat sources make use of standard headers | ||
| 322 | <CODE><stdbool.h></CODE> and <CODE><stdint.h></CODE>, which have | ||
| 323 | been part of the ISO C Standard Library since 1999. | ||
| 324 | With any recent compiler, these standard headers are likely to be supported, | ||
| 325 | even if the compiler does not claim complete conformance to the latest ISO C | ||
| 326 | Standard. | ||
| 327 | For older or nonstandard compilers, substitutes for | ||
| 328 | <CODE><stdbool.h></CODE> and <CODE><stdint.h></CODE> may need to be | ||
| 329 | created. | ||
| 330 | SoftFloat depends on these names from <CODE><stdbool.h></CODE>: | ||

| 362 | <H3>5.2. Specializing Floating-Point Behavior</H3> | ||
| 363 | |||
| 364 | <P> | ||
| 365 | The IEEE Floating-Point Standard allows for some flexibility in a conforming | ||
| 366 | implementation, particularly concerning NaNs. | ||
| 367 | The SoftFloat <CODE>source</CODE> directory is supplied with some | ||
| 368 | <I>specialization</I> subdirectories containing possible definitions for this | ||
| 369 | implementation-specific behavior. | ||
| 370 | For example, the <CODE>8086</CODE> and <NOBR><CODE>8086-SSE</CODE></NOBR> | ||
| 371 | subdirectories have source files that specialize SoftFloat’s behavior to | ||
| 372 | match that of Intel’s x86 line of processors. | ||
| 373 | The files in a specialization subdirectory must determine: | ||
| 374 | <UL> | ||
| 375 | <LI> | ||
| 376 | whether tininess for underflow is detected before or after rounding by default; | ||
| 377 | <LI> | ||
| 378 | how signaling NaNs are distinguished from quiet NaNs; | ||
| 379 | <LI> | ||
| 380 | what (if anything) special happens when exceptions are raised; | ||
| 381 | <LI> | ||
| 382 | the default generated quiet NaNs; | ||
| 383 | <LI> | ||
| 384 | how NaNs are propagated from function inputs to output; and | ||
| 385 | <LI> | ||
| 386 | the integer results returned when conversions to integer type raise the | ||
| 387 | <I>invalid</I> exception. | ||
| 388 | </UL> | ||
| 389 | </P> | ||
| 390 | |||
| 391 | <P> | ||
| 392 | As provided, the build process for a target expects to involve exactly | ||
| 393 | <EM>one</EM> specialization directory that defines <EM>all</EM> of these | ||
| 394 | implementation-specific details for the target. | ||
| 395 | A specialization directory such as <CODE>8086</CODE> is expected to contain a | ||
| 396 | header file called <CODE>specialize.h</CODE>, together with whatever other | ||
| 397 | source files are needed to complete the specialization. | ||
| 398 | </P> | ||
| 399 | |||
| 400 | <P> | ||
| 401 | A new build target may use an existing specialization, such as the ones | ||
| 402 | provided by the <CODE>8086</CODE> and <NOBR><CODE>8086-SSE</CODE></NOBR> | ||
| 403 | subdirectories. | ||
| 404 | If a build target needs a new specialization, different from any existing ones, | ||
| 405 | it is recommended that a new specialization subdirectory be created in the | ||
| 406 | <CODE>source</CODE> directory for this purpose. | ||
| 407 | The <CODE>specialize.h</CODE> header file from any of the provided | ||
| 408 | specialization subdirectories can be used as a model for what definitions are | ||
| 409 | needed. | ||

| 413 | <H3>5.3. Macros for Build Options</H3> | ||
| 414 | |||
| 415 | <P> | ||
| 416 | The SoftFloat source files adapt the floating-point implementation according to | ||
| 417 | several C preprocessor macros: | ||
| 418 | <BLOCKQUOTE> | ||
| 419 | <DL> | ||
| 420 | <DT><CODE>LITTLEENDIAN</CODE> | ||
| 421 | <DD> | ||
| 422 | Must be defined for little-endian machines; must not be defined for big-endian | ||
| 423 | machines. | ||
| 424 | <DT><CODE>INLINE</CODE> | ||
| 425 | <DD> | ||
| 426 | Specifies the sequence of tokens used to indicate that a C function should be | ||
| 427 | inlined. | ||
| 428 | If macro <CODE>INLINE_LEVEL</CODE> is defined with a value of 1 or higher, this | ||
| 429 | macro must be defined; otherwise, this macro is ignored and need not be | ||
| 430 | defined. | ||
| 431 | For compilers that conform to the C Standard’s rules for inline | ||
| 432 | functions, this macro can be defined as the single keyword <CODE>inline</CODE>. | ||
| 433 | For other compilers that follow a convention pre-dating the standardization of | ||
| 434 | <CODE>inline</CODE>, this macro may need to be defined to <CODE>extern</CODE> | ||
| 435 | <CODE>inline</CODE>. | ||
| 436 | <DT><CODE>THREAD_LOCAL</CODE> | ||
| 437 | <DD> | ||
| 438 | Can be defined to a sequence of tokens that, when appearing at the start of a | ||
| 439 | variable declaration, indicates to the C compiler that the variable is | ||
| 440 | <I>per-thread</I>, meaning that each execution thread gets its own separate | ||
| 441 | instance of the variable. | ||
| 442 | This macro is used in header <CODE>softfloat.h</CODE> in the declarations of | ||
| 443 | variables <CODE>softfloat_roundingMode</CODE>, | ||
| 444 | <CODE>softfloat_detectTininess</CODE>, <CODE>extF80_roundingPrecision</CODE>, | ||
| 445 | and <CODE>softfloat_exceptionFlags</CODE>. | ||
| 446 | If macro <CODE>THREAD_LOCAL</CODE> is left undefined, these variables will | ||
| 447 | default to being ordinary global variables. | ||
| 448 | Depending on the compiler, possible valid definitions of this macro include | ||
| 449 | <CODE>_Thread_local</CODE> and <CODE>__thread</CODE>. | ||
| 450 | </DL> | ||
| 451 | <DL> | ||
| 452 | <DT><CODE>SOFTFLOAT_ROUND_ODD</CODE> | ||
| 453 | <DD> | ||
| 454 | Can be defined to enable support for optional rounding mode | ||
| 455 | <CODE>softfloat_round_odd</CODE>. | ||
| 456 | </DL> | ||
| 457 | <DL> | ||
| 458 | <DT><CODE>INLINE_LEVEL</CODE> | ||
| 459 | <DD> | ||
| 460 | Can be defined to an integer to determine the degree of inlining requested of | ||
| 461 | the compiler. | ||
| 462 | Larger numbers request that more inlining be done. | ||
| 463 | If this macro is not defined or is defined to a value less <NOBR>than 1</NOBR> | ||
| 464 | (zero or negative), no inlining is requested. | ||
| 465 | The maximum effective value is no higher <NOBR>than 5</NOBR>. | ||
| 466 | Defining this macro to a value greater than 5 is the same as defining it | ||
| 467 | <NOBR>to 5</NOBR>. | ||
| 468 | <DT><CODE>SOFTFLOAT_FAST_INT64</CODE> | ||
| 469 | <DD> | ||
| 470 | Can be defined to indicate that the build target’s implementation of | ||
| 471 | <NOBR>64-bit</NOBR> arithmetic is efficient. | ||
| 472 | For newer <NOBR>64-bit</NOBR> processors, this macro should usually be defined. | ||
| 473 | For very small microprocessors whose buses and registers are <NOBR>8-bit</NOBR> | ||
| 474 | or <NOBR>16-bit</NOBR> in size, this macro should usually not be defined. | ||
| 475 | Whether this macro should be defined for a <NOBR>32-bit</NOBR> processor may | ||
| 476 | depend on the target machine and the applications that will use SoftFloat. | ||
| 477 | <DT><CODE>SOFTFLOAT_FAST_DIV32TO16</CODE> | ||
| 478 | <DD> | ||
| 479 | Can be defined to indicate that the target’s division operator | ||
| 480 | <NOBR>in C</NOBR> (written as <CODE>/</CODE>) is reasonably efficient for | ||
| 481 | dividing a <NOBR>32-bit</NOBR> unsigned integer by a <NOBR>16-bit</NOBR> | ||
| 482 | unsigned integer. | ||
| 483 | Setting this macro may affect the performance of function <CODE>f16_div</CODE>. | ||
| 484 | <DT><CODE>SOFTFLOAT_FAST_DIV64TO32</CODE> | ||
| 485 | <DD> | ||
| 486 | Can be defined to indicate that the target’s division operator | ||
| 487 | <NOBR>in C</NOBR> (written as <CODE>/</CODE>) is reasonably efficient for | ||
| 488 | dividing a <NOBR>64-bit</NOBR> unsigned integer by a <NOBR>32-bit</NOBR> | ||
| 489 | unsigned integer. | ||
| 490 | Setting this macro may affect the performance of division, remainder, and | ||
| 491 | square root operations other than <CODE>f16_div</CODE>. | ||
| 492 | </DL> | ||
| 493 | </BLOCKQUOTE> | ||
| 494 | </P> | ||
| 495 | |||
| 496 | <P> | ||
| 497 | Following the usual custom <NOBR>for C</NOBR>, for most of these macros (all | ||
| 498 | except <CODE>INLINE</CODE>, <CODE>THREAD_LOCAL</CODE>, and | ||
| 499 | <CODE>INLINE_LEVEL</CODE>), the content of any definition is irrelevant; | ||
| 500 | what matters is a macro’s effect on <CODE>#ifdef</CODE> directives. | ||
| 501 | </P> | ||
| 502 | |||
| 503 | <P> | ||
| 504 | It is recommended that any definitions of macros <CODE>LITTLEENDIAN</CODE>, | ||
| 505 | <CODE>INLINE</CODE>, and <CODE>THREAD_LOCAL</CODE> be made in a build | ||
| 506 | target’s <CODE>platform.h</CODE> header file, because these macros are | ||
| 507 | expected to be determined inflexibly by the target machine and compiler. | ||
| 508 | The other five macros select options and control optimization, and thus might | ||
| 509 | be better located in the target’s Makefile (or its equivalent). | ||
| 510 | </P> | ||
| 511 | |||
| 512 | |||
| 513 | <H3>5.4. Adapting a Template Target Directory</H3> | ||
| 514 | |||
| 515 | <P> | ||
| 516 | In the <CODE>build</CODE> directory, two <CODE>template</CODE> subdirectories | ||
| 517 | provide models for new target directories. | ||
| 518 | Two different templates exist because different functions are needed in the | ||
| 519 | SoftFloat library depending on whether macro <CODE>SOFTFLOAT_FAST_INT64</CODE> | ||
| 520 | is defined. | ||
| 521 | If macro <CODE>SOFTFLOAT_FAST_INT64</CODE> will be defined, | ||
| 522 | <NOBR><CODE>template-FAST_INT64</CODE></NOBR> is the template to use; | ||
| 523 | otherwise, <NOBR><CODE>template-not-FAST_INT64</CODE></NOBR> is the appropriate | ||
| 524 | template. | ||
| 525 | A new target directory can be created by copying the correct template directory | ||
| 526 | and editing the files inside. | ||
| 527 | To avoid confusion, it would be wise to refrain from editing the files within a | ||
| 528 | template directory directly. | ||
| 529 | </P> | ||
| 530 | |||
| 531 | |||
| 532 | <H3>5.5. Target-Specific Optimization of Primitive Functions</H3> | ||
| 533 | |||
| 534 | <P> | ||
| 535 | Header file <CODE>primitives.h</CODE> (in directory | ||
| 536 | <CODE>source/include</CODE>) declares macros and functions for numerous | ||
| 537 | underlying arithmetic operations upon which many of SoftFloat’s | ||
| 538 | floating-point functions are ultimately built. | ||
| 539 | The SoftFloat sources include implementations of all of these functions/macros, | ||
| 540 | written as standard C code, so a complete and correct SoftFloat library can be | ||
| 541 | created using only the supplied code for all functions. | ||
| 542 | However, for many targets, SoftFloat’s performance can be improved by | ||
| 543 | substituting target-specific implementations of some of the functions/macros | ||
| 544 | declared in <CODE>primitives.h</CODE>. | ||
| 545 | </P> | ||
| 546 | |||
| 547 | <P> | ||
| 548 | For example, <CODE>primitives.h</CODE> declares a function called | ||
| 549 | <CODE>softfloat_countLeadingZeros32</CODE> that takes an unsigned | ||
| 550 | <NOBR>32-bit</NOBR> integer as an argument and returns the number of the | ||
| 551 | integer’s most-significant bits that are zeros. | ||
| 552 | While the SoftFloat sources include an implementation of this function written | ||
| 553 | in <NOBR>standard C</NOBR>, many processors can perform this same function | ||
| 554 | directly in only one or two machine instructions. | ||
| 555 | An alternative, target-specific implementation that maps to those instructions | ||
| 556 | is likely to be more efficient than the generic C code from the SoftFloat | ||
| 557 | package. | ||
| 558 | </P> | ||
| 559 | |||
| 560 | <P> | ||
| 561 | A build target can replace the supplied version of any function or macro of | ||
| 562 | <CODE>primitives.h</CODE> by defining a macro with the same name in the | ||
| 563 | target’s <CODE>platform.h</CODE> header file. | ||
| 564 | For this purpose, it may be helpful for <CODE>platform.h</CODE> to | ||
| 565 | <CODE>#include</CODE> header file <CODE>primitiveTypes.h</CODE>, which defines | ||
| 566 | types used for arguments and results of functions declared in | ||
| 567 | <CODE>primitives.h</CODE>. | ||
| 568 | When a desired replacement implementation is a function, not a macro, it is | ||
| 569 | sufficient for <CODE>platform.h</CODE> to include the line | ||
| 570 | <BLOCKQUOTE> | ||
| 571 | <PRE> | ||
| 572 | #define <<I>function-name</I>> <<I>function-name</I>> | ||

| 574 | </BLOCKQUOTE> | ||
| 575 | where <NOBR><CODE><<I>function-name</I>></CODE></NOBR> is the name of the | ||
| 576 | function. | ||
| 577 | This technically defines <NOBR><CODE><<I>function-name</I>></CODE></NOBR> | ||
| 578 | as a macro, but one that resolves to the same name, which may then be a | ||
| 579 | function. | ||
| 580 | (A preprocessor that conforms to the C Standard must limit recursive macro | ||
| 581 | expansion from being applied more than once.) | ||

| 585 | <H2>6. Testing SoftFloat</H2> | ||
| 586 | |||
| 587 | <P> | ||
| 588 | SoftFloat can be tested using the <CODE>testsoftfloat</CODE> program by the | ||
| 589 | same author. | ||
| 590 | This program is part of the Berkeley TestFloat package available at the Web | ||

| 592 | <A HREF="http://www.jhauser.us/arithmetic/TestFloat.html"><NOBR><CODE>http://www.jhauser.us/arithmetic/TestFloat.html</CODE></NOBR></A>. | ||
| 593 | The TestFloat package also has a program called <CODE>timesoftfloat</CODE> that | ||
| 594 | measures the speed of SoftFloat’s floating-point functions. | ||

| 598 | <H2>7. Providing SoftFloat as a Common Library for Applications</H2> | ||
| 599 | |||
| 600 | <P> | ||
| 601 | Header file <CODE>softfloat.h</CODE> defines the SoftFloat interface as seen by | ||
| 602 | clients. | ||
| 603 | If the SoftFloat library will be made a common library for programs on a | ||
| 604 | system, the supplied <CODE>softfloat.h</CODE> has a couple of deficiencies for | ||
| 605 | this purpose: | ||
| 606 | <UL> | ||
| 607 | <LI> | ||
| 608 | As supplied, <CODE>softfloat.h</CODE> depends on another header, | ||
| 609 | <CODE>softfloat_types.h</CODE>, that is not intended for public use but which | ||
| 610 | must also be visible to the programmer’s compiler. | ||
| 611 | <LI> | ||
| 612 | More troubling, at the time <CODE>softfloat.h</CODE> is included in a C source | ||
| 613 | file, macros <CODE>SOFTFLOAT_FAST_INT64</CODE> and <CODE>THREAD_LOCAL</CODE> | ||
| 614 | must be defined, or not defined, consistent with how these macro were defined | ||
| 615 | when the SoftFloat library was built. | ||
| 616 | </UL> | ||
| 617 | In the situation that new programs may regularly <CODE>#include</CODE> header | ||
| 618 | file <CODE>softfloat.h</CODE>, it is recommended that a custom, self-contained | ||
| 619 | version of this header file be created that eliminates these issues. | ||

| 69 | <H2>1. Introduction</H2> | ||
| 70 | |||
| 71 | <P> | ||
| 72 | Berkeley SoftFloat is a software implementation of binary floating-point that | ||
| 73 | conforms to the IEEE Standard for Floating-Point Arithmetic. | ||
| 74 | The current release supports five binary formats: <NOBR>16-bit</NOBR> | ||
| 75 | half-precision, <NOBR>32-bit</NOBR> single-precision, <NOBR>64-bit</NOBR> | ||
| 76 | double-precision, <NOBR>80-bit</NOBR> double-extended-precision, and | ||
| 77 | <NOBR>128-bit</NOBR> quadruple-precision. | ||
| 78 | The following functions are supported for each format: | ||
| 79 | <UL> | ||
| 80 | <LI> | ||
| 81 | addition, subtraction, multiplication, division, and square root; | ||
| 82 | <LI> | ||
| 83 | fused multiply-add as defined by the IEEE Standard, except for | ||
| 84 | <NOBR>80-bit</NOBR> double-extended-precision; | ||
| 85 | <LI> | ||
| 86 | remainder as defined by the IEEE Standard; | ||
| 87 | <LI> | ||
| 88 | round to integral value; | ||
| 89 | <LI> | ||
| 90 | comparisons; | ||
| 91 | <LI> | ||
| 92 | conversions to/from other supported formats; and | ||
| 93 | <LI> | ||
| 94 | conversions to/from <NOBR>32-bit</NOBR> and <NOBR>64-bit</NOBR> integers, | ||
| 95 | signed and unsigned. | ||
| 96 | </UL> | ||
| 97 | All operations required by the original 1985 version of the IEEE Floating-Point | ||
| 98 | Standard are implemented, except for conversions to and from decimal. | ||
| 99 | </P> | ||
| 100 | |||
| 101 | <P> | ||
| 102 | This document gives information about the types defined and the routines | ||
| 103 | implemented by SoftFloat. | ||
| 104 | It does not attempt to define or explain the IEEE Floating-Point Standard. | ||
| 105 | Information about the standard is available elsewhere. | ||
| 106 | </P> | ||
| 107 | |||
| 108 | <P> | ||
| 109 | The current version of SoftFloat is <NOBR>Release 3d</NOBR>. | ||
| 110 | This release fixes bugs that were found in the square root functions for the | ||
| 111 | <NOBR>64-bit</NOBR>, <NOBR>80-bit</NOBR>, and <NOBR>128-bit</NOBR> | ||
| 112 | floating-point formats. | ||
| 113 | (Thanks to Alexei Sibidanov at the University of Victoria for reporting an | ||
| 114 | incorrect result.) | ||
| 115 | The bugs affected all prior <NOBR>Release-3</NOBR> versions of SoftFloat. | ||
| 116 | The flaw in the <NOBR>64-bit</NOBR> floating-point square root function was of | ||
| 117 | very minor impact, causing a <NOBR>1-ulp</NOBR> error (<NOBR>1 unit</NOBR> in | ||
| 118 | the last place) a few times out of a billion. | ||
| 119 | The bugs in the <NOBR>80-bit</NOBR> and <NOBR>128-bit</NOBR> square root | ||
| 120 | functions were more serious. | ||
| 121 | Although incorrect results again occurred only a few times out of a billion, | ||
| 122 | when they did occur a large portion of the less-significant bits could be | ||
| 123 | wrong. | ||
| 124 | </P> | ||
| 125 | |||
| 126 | <P> | ||
| 127 | <NOBR>Release 3d</NOBR> makes no changes to the SoftFloat library interface | ||
| 128 | compared to the previous <NOBR>Release 3c</NOBR>. | ||
| 129 | Since the original <NOBR>Release 3</NOBR>, the main changes to the interface | ||
| 130 | have been that <NOBR>Release 3b</NOBR> added support for the | ||
| 131 | <NOBR>16-bit</NOBR> half-precision format, and <NOBR>Release 3c</NOBR> added | ||
| 132 | optional support for a rarely used rounding mode, <I>round to odd</I>, also | ||
| 133 | known as <I>jamming</I>. | ||
| 134 | For more about the evolution of SoftFloat releases, see | ||
| 135 | <A HREF="SoftFloat-history.html"><NOBR><CODE>SoftFloat-history.html</CODE></NOBR></A>. | ||
| 136 | </P> | ||
| 137 | |||
| 138 | <P> | ||
| 139 | The functional interface of SoftFloat <NOBR>Release 3</NOBR> and later differs | ||
| 140 | in many details from the releases that came before. | ||
| 141 | For specifics of these differences, see <NOBR>section 9</NOBR> below, | ||
| 142 | <I>Changes from SoftFloat <NOBR>Release 2</NOBR></I>. | ||
| 143 | </P> | ||
| 144 | |||
| 145 | |||
| 146 | <H2>2. Limitations</H2> | ||
| 147 | |||
| 148 | <P> | ||
| 149 | SoftFloat assumes the computer has an addressable byte size of 8 or | ||
| 150 | <NOBR>16 bits</NOBR>. | ||
| 151 | (Nearly all computers in use today have <NOBR>8-bit</NOBR> bytes.) | ||
| 152 | </P> | ||
| 153 | |||
| 154 | <P> | ||
| 155 | SoftFloat is written in C and is designed to work with other C code. | ||
| 156 | The C compiler used must conform at a minimum to the 1989 ANSI standard for the | ||
| 157 | C language (same as the 1990 ISO standard) and must in addition support basic | ||
| 158 | arithmetic on <NOBR>64-bit</NOBR> integers. | ||
| 159 | Earlier releases of SoftFloat included implementations of <NOBR>32-bit</NOBR> | ||
| 160 | single-precision and <NOBR>64-bit</NOBR> double-precision floating-point that | ||
| 161 | did not require <NOBR>64-bit</NOBR> integers, but this option is not supported | ||
| 162 | starting with <NOBR>Release 3</NOBR>. | ||
| 163 | Since 1999, ISO standards for C have mandated compiler support for | ||
| 164 | <NOBR>64-bit</NOBR> integers. | ||
| 165 | A compiler conforming to the 1999 C Standard or later is recommended but not | ||
| 166 | strictly required. | ||
| 167 | </P> | ||
| 168 | |||
| 169 | <P> | ||
| 170 | Most operations not required by the original 1985 version of the IEEE | ||
| 171 | Floating-Point Standard but added in the 2008 version are not yet supported in | ||
| 172 | SoftFloat <NOBR>Release 3d</NOBR>. | ||

| 417 | |||
| 418 | <P> | ||
| 419 | Because the <NOBR>80-bit</NOBR> double-extended-precision format, | ||
| 420 | <CODE>extFloat80_t</CODE>, stores an explicit leading significand bit, many | ||
| 421 | finite floating-point numbers are encodable in this type in multiple equivalent | ||
| 422 | forms. | ||
| 423 | Of these multiple encodings, there is always a unique one with the least | ||
| 424 | encoded exponent value, and this encoding is considered the <I>canonical</I> | ||
| 425 | representation of the floating-point number. | ||
| 426 | Any other equivalent representations (having a higher encoded exponent value) | ||
| 427 | are <I>non-canonical</I>. | ||
| 428 | For a value in the subnormal range (including zero), the canonical | ||
| 429 | representation always has an encoded exponent of zero and a leading significand | ||
| 430 | bit <NOBR>of 0</NOBR>. | ||
| 431 | For finite values outside the subnormal range, the canonical representation | ||
| 432 | always has an encoded exponent that is nonzero and a leading significand bit | ||
| 433 | <NOBR>of 1</NOBR>. | ||
| 434 | </P> | ||
| 435 | |||
| 436 | <P> | ||
| 437 | For an infinity or NaN, the leading significand bit is similarly expected to | ||
| 438 | <NOBR>be 1</NOBR>. | ||
| 439 | An infinity or NaN with a leading significand bit <NOBR>of 0</NOBR> is again | ||
| 440 | considered non-canonical. | ||
| 441 | Hence, altogether, to be canonical, a value of type <CODE>extFloat80_t</CODE> | ||
| 442 | must have a leading significand bit <NOBR>of 1</NOBR>, unless the value is | ||
| 443 | subnormal or zero, in which case the leading significand bit and the encoded | ||
| 444 | exponent must both be zero. | ||
| 445 | </P> | ||
| 446 | |||
| 447 | <P> | ||
| 448 | SoftFloat's functions are not guaranteed to operate as expected when inputs of | ||
| 449 | type <CODE>extFloat80_t</CODE> are non-canonical. | ||
| 450 | Assuming all of a function’s <CODE>extFloat80_t</CODE> inputs (if any) | ||
| 451 | are canonical, function outputs of type <CODE>extFloat80_t</CODE> will always | ||
| 452 | be canonical. | ||

| 459 | <NOBR>80-bit</NOBR> or <NOBR>128-bit</NOBR> floating-point formats) are in all | ||
| 460 | cases passed as function arguments by value. | ||
| 461 | Likewise, when an output of a function is no more than <NOBR>64 bits</NOBR>, it | ||
| 462 | is always returned directly as the function result. | ||
| 463 | Thus, for example, the SoftFloat function for adding two <NOBR>64-bit</NOBR> | ||
| 464 | floating-point values has this simple signature: | ||
| 465 | <BLOCKQUOTE> | ||
| 466 | <CODE>float64_t f64_add( float64_t, float64_t );</CODE> | ||
| 467 | </BLOCKQUOTE> | ||
| 468 | </P> | ||
| 469 | |||
| 470 | <P> | ||
| 471 | The story is more complex when function inputs and outputs are | ||
| 472 | <NOBR>80-bit</NOBR> and <NOBR>128-bit</NOBR> floating-point. | ||
| 473 | For these types, SoftFloat always provides a function that passes these larger | ||
| 474 | values into or out of the function indirectly, via pointers. | ||
| 475 | For example, for adding two <NOBR>128-bit</NOBR> floating-point values, | ||
| 476 | SoftFloat supplies this function: | ||
| 477 | <BLOCKQUOTE> | ||
| 478 | <CODE>void f128M_add( const float128_t *, const float128_t *, float128_t * );</CODE> | ||
| 479 | </BLOCKQUOTE> | ||
| 480 | The first two arguments point to the values to be added, and the last argument | ||
| 481 | points to the location where the sum will be stored. | ||
| 482 | The <CODE>M</CODE> in the name <CODE>f128M_add</CODE> is mnemonic for the fact | ||
| 483 | that the <NOBR>128-bit</NOBR> inputs and outputs are “in memory”, | ||
| 484 | pointed to by pointer arguments. | ||
| 485 | </P> | ||
| 486 | |||
| 487 | <P> | ||
| 488 | All ports of SoftFloat implement these <I>pass-by-pointer</I> functions for | ||
| 489 | types <CODE>extFloat80_t</CODE> and <CODE>float128_t</CODE>. | ||
| 490 | At the same time, SoftFloat ports may also implement alternate versions of | ||
| 491 | these same functions that pass <CODE>extFloat80_t</CODE> and | ||
| 492 | <CODE>float128_t</CODE> by value, like the smaller formats. | ||
| 493 | Thus, besides the function with name <CODE>f128M_add</CODE> shown above, a | ||
| 494 | SoftFloat port may also supply an equivalent function with this signature: | ||
| 495 | <BLOCKQUOTE> | ||
| 496 | <CODE>float128_t f128_add( float128_t, float128_t );</CODE> | ||
| 497 | </BLOCKQUOTE> | ||
| 498 | </P> | ||
| 499 | |||
| 500 | <P> | ||
| 501 | As a general rule, on computers where the machine word size is | ||
| 502 | <NOBR>32 bits</NOBR> or smaller, only the pass-by-pointer versions of functions | ||
| 503 | (e.g., <CODE>f128M_add</CODE>) are provided for types <CODE>extFloat80_t</CODE> | ||
| 504 | and <CODE>float128_t</CODE>, because passing such large types directly can have | ||
| 505 | significant extra cost. | ||
| 506 | On computers where the word size is <NOBR>64 bits</NOBR> or larger, both | ||
| 507 | function versions (<CODE>f128M_add</CODE> and <CODE>f128_add</CODE>) are | ||
| 508 | provided, because the cost of passing by value is then more reasonable. | ||
| 509 | Applications that must be portable accross both classes of computers must use | ||
| 510 | the pointer-based functions, as these are always implemented. | ||
| 511 | However, if it is known that SoftFloat includes the by-value functions for all | ||
| 512 | platforms of interest, programmers can use whichever version they prefer. | ||

| 517 | |||
| 518 | <P> | ||
| 519 | In addition to the variables and functions documented here, SoftFloat defines | ||
| 520 | some symbol names for its own private use. | ||
| 521 | These private names always begin with the prefix | ||
| 522 | ‘<CODE>softfloat_</CODE>’. | ||

| 525 | are reserved for possible use by SoftFloat. | ||

| 608 | <P> | ||
| 609 | In the terminology of the IEEE Standard, SoftFloat can detect tininess for | ||
| 610 | underflow either before or after rounding. | ||
| 611 | The choice is made by the global variable | ||
| 612 | <BLOCKQUOTE> | ||
| 613 | <CODE>uint_fast8_t softfloat_detectTininess;</CODE> | ||

| 620 | Detecting tininess after rounding is usually better because it results in fewer | ||

| 622 | The other option is provided for compatibility with some systems. | ||
| 623 | Like most systems (and as required by the newer 2008 IEEE Standard), SoftFloat | ||

| 1351 | <H3>9.2. Changes to Function Arguments</H3> | ||
| 1352 | |||
| 1353 | <P> | ||
| 1354 | Besides simple name changes, some operations were given a different interface | ||
| 1355 | in <NOBR>Release 3</NOBR> than they had in <NOBR>Release 2</NOBR>: | ||

| 1359 | <P> | ||
| 1360 | Since <NOBR>Release 3</NOBR>, integer arguments and results of functions have | ||
| 1361 | standard types from header <CODE><stdint.h></CODE>, such as | ||
| 1362 | <CODE>uint32_t</CODE>, whereas previously their types could be defined | ||
| 1363 | differently for each port of SoftFloat, usually using traditional C types such | ||
| 1364 | as <CODE>unsigned</CODE> <CODE>int</CODE>. | ||
| 1365 | Likewise, functions in <NOBR>Release 3</NOBR> and later pass Booleans as | ||
| 1366 | standard type <CODE>bool</CODE> from <CODE><stdbool.h></CODE>, whereas | ||
| 1367 | previously these were again passed as a port-specific type (usually | ||
| 1368 | <CODE>int</CODE>). | ||

| 1373 | As explained earlier in <NOBR>section 4.5</NOBR>, <I>Conventions for Passing | ||
| 1374 | Arguments and Results</I>, SoftFloat functions in <NOBR>Release 3</NOBR> and | ||
| 1375 | later may pass <NOBR>80-bit</NOBR> and <NOBR>128-bit</NOBR> floating-point | ||
| 1376 | values through pointers, meaning that functions take pointer arguments and then | ||
| 1377 | read or write floating-point values at the locations indicated by the pointers. | ||
| 1378 | In <NOBR>Release 2</NOBR>, floating-point arguments and results were always | ||
| 1379 | passed by value, regardless of their size. | ||
| 1380 | </P> | ||
| 1381 | |||
| 1382 | <LI> | ||
| 1383 | <P> | ||
| 1384 | Functions that round to an integer have additional | ||
| 1385 | <CODE><I>roundingMode</I></CODE> and <CODE><I>exact</I></CODE> arguments that | ||
| 1386 | they did not have in <NOBR>Release 2</NOBR>. | ||
| 1387 | Refer to sections 8.2 <NOBR>and 8.7</NOBR> for descriptions of these functions | ||
| 1388 | since <NOBR>Release 3</NOBR>. | ||
| 1389 | For <NOBR>Release 2</NOBR>, the rounding mode, when needed, was taken from the | ||
| 1390 | same global variable that affects the basic arithmetic operations (now called | ||
| 1391 | <CODE>softfloat_roundingMode</CODE> but previously known as | ||
| 1392 | <CODE>float_rounding_mode</CODE>). | ||
| 1393 | Also, for <NOBR>Release 2</NOBR>, if the original floating-point input was not | ||
| 1394 | an exact integer value, and if the <I>invalid</I> exception was not raised by | ||
| 1395 | the function, the <I>inexact</I> exception was always raised. | ||
| 1396 | <NOBR>Release 2</NOBR> had no option to suppress raising <I>inexact</I> in this | ||
| 1397 | case. | ||
| 1398 | Applications using SoftFloat <NOBR>Release 3</NOBR> or later can get the same | ||
| 1399 | effect as <NOBR>Release 2</NOBR> by passing variable | ||
| 1400 | <CODE>softfloat_roundingMode</CODE> for argument | ||
| 1401 | <CODE><I>roundingMode</I></CODE> and <CODE>true</CODE> for argument | ||
| 1402 | <CODE><I>exact</I></CODE>. | ||

| 1417 | A port of SoftFloat can now define any of the floating-point types | ||
| 1418 | <CODE>float32_t</CODE>, <CODE>float64_t</CODE>, <CODE>extFloat80_t</CODE>, and | ||
| 1419 | <CODE>float128_t</CODE> as aliases for C’s standard floating-point types | ||
| 1420 | <CODE>float</CODE>, <CODE>double</CODE>, and <CODE>long</CODE> | ||
| 1421 | <CODE>double</CODE>, using either <CODE>#define</CODE> or <CODE>typedef</CODE>. | ||
| 1422 | This potential convenience was not supported under <NOBR>Release 2</NOBR>. | ||
| 1423 | </P> | ||
| 1424 | |||
| 1425 | <P> | ||
| 1426 | (Note, however, that there may be a performance cost to defining | ||
| 1427 | SoftFloat’s floating-point types this way, depending on the platform and | ||
| 1428 | the applications using SoftFloat. | ||
| 1429 | Ports of SoftFloat may choose to forgo the convenience in favor of better | ||
| 1430 | speed.) | ||
| 1431 | </P> | ||

| 1441 | Functions have been added for converting between the floating-point types and | ||
| 1442 | unsigned integers. | ||
| 1443 | <NOBR>Release 2</NOBR> supported only signed integers, not unsigned. | ||

| 1457 | maximum magnitude, away from zero), and, as of <NOBR>Release 3c</NOBR>, | ||
| 1458 | optional <CODE>softfloat_round_odd</CODE> (round to odd, also known as | ||
| 1459 | jamming). | ||

| 1465 | <H3>9.4. Better Compatibility with the C Language</H3> | ||
| 1466 | |||
| 1467 | <P> | ||
| 1468 | <NOBR>Release 3</NOBR> of SoftFloat was written to conform better to the ISO C | ||
| 1469 | Standard’s rules for portability. | ||
| 1470 | For example, older releases of SoftFloat employed type conversions in ways | ||
| 1471 | that, while commonly practiced, are not fully defined by the C Standard. | ||
| 1472 | Such problematic type conversions have generally been replaced by the use of | ||
| 1473 | unions, the behavior around which is more strictly regulated these days. | ||
| 1474 | </P> | ||
| 1475 | |||
| 1476 | <H3>9.5. New Organization as a Library</H3> | ||
| 1477 | |||
| 1478 | <P> | ||
| 1479 | Starting with <NOBR>Release 3</NOBR>, SoftFloat now builds as a library. | ||
| 1480 | Previously, SoftFloat compiled into a single, monolithic object file containing | ||
| 1481 | all the SoftFloat functions, with the consequence that a program linking with | ||
| 1482 | SoftFloat would get every SoftFloat function in its binary file even if only a | ||
| 1483 | few functions were actually used. | ||
| 1484 | With SoftFloat in the form of a library, a program that is linked by a standard | ||
| 1485 | linker will include only those functions of SoftFloat that it needs and no | ||
| 1486 | others. | ||
| 1487 | </P> | ||
| 1488 | |||
| 1489 | <H3>9.6. Optimization Gains (and Losses)</H3> | ||
| 1490 | |||
| 1491 | <P> | ||
| 1492 | Individual SoftFloat functions have been variously improved in | ||
| 1493 | <NOBR>Release 3</NOBR> compared to earlier releases. | ||
| 1494 | In particular, better, faster algorithms have been deployed for the operations | ||
| 1495 | of division, square root, and remainder. | ||
| 1496 | For functions operating on the larger <NOBR>80-bit</NOBR> and | ||
| 1497 | <NOBR>128-bit</NOBR> formats, <CODE>extFloat80_t</CODE> and | ||
| 1498 | <CODE>float128_t</CODE>, code size has also generally been reduced. | ||
| 1499 | </P> | ||
| 1500 | |||
| 1501 | <P> | ||
| 1502 | However, because <NOBR>Release 2</NOBR> compiled all of SoftFloat together as a | ||
| 1503 | single object file, compilers could make optimizations across function calls | ||
| 1504 | when one SoftFloat function calls another. | ||
| 1505 | Now that the functions of SoftFloat are compiled separately and only afterward | ||
| 1506 | linked together into a program, there is not usually the same opportunity to | ||
| 1507 | optimize across function calls. | ||
| 1508 | Some loss of speed has been observed due to this change. | ||
| 1509 | </P> | ||

| 1512 | <H2>10. Future Directions</H2> | ||

| 193 | | bits and 30 fraction bits. The format of 'a' is determined by 'oddExpA', | ||
| 194 | | which must be either 0 or 1. If 'oddExpA' is 1, 'a' is interpreted as | ||
| 195 | | having one integer bit, and if 'oddExpA' is 0, 'a' is interpreted as having | ||
| 196 | | two integer bits. The 'a' input must be "normalized", meaning that its | ||
| 197 | | most-significant bit (bit 31) must be 1. Thus, if A is the value of the | ||
| 198 | | fixed-point interpretation of 'a', it follows that 1 <= A < 2 when 'oddExpA' | ||
| 199 | | is 1, and 2 <= A < 4 when 'oddExpA' is 0. | ||
| 200 | | The returned value is interpreted as a pure unsigned fraction, having | ||
| 201 | | no integer bits and 32 fraction bits. The approximation returned is never | ||
| 202 | | greater than the true reciprocal 1/sqrt(A), and it differs from the true | ||
| 203 | | reciprocal by at most 2.06 ulp (units in the last place). The approximation | ||
| 204 | | returned is also always within the range 0.5 to 1; thus, the most- | ||
| 205 | | significant bit of the result is always set. | ||
