19	24	ELF Improvements
20	25	----------------
21	26
22		* lld is now able to overcome MIPS GOT entries number limitation
23		and generate multi-GOT if necessary.
	27	* lld now supports RISC-V. (`r339364
	28	<https://reviews.llvm.org/rL339364>`_)
	29
	30	* Default image base address has changed from 65536 to 2 MiB for i386
	31	and 4 MiB for AArch64 to make lld-generated executables work better
	32	with automatic superpage promotion. FreeBSD can promote contiguous
	33	non-superpages to a superpage if they are aligned to the superpage
	34	size. (`r342746 <https://reviews.llvm.org/rL342746>`_)
	35
	36	* lld/Hexagon can now link Linux kernel and musl libc for Qualcomm
	37	Hexagon ISA.
24	38
25		* lld is now able to produce MIPS position-independent executable (PIE).
	39	* Initial MSP430 ISA support has landed.
26	40
27		* Fixed MIPS TLS GOT entries for local symbols in shared libraries.
	41	* The following flags have been added: ``-z interpose``, ``-z global``
28	42
29		* Fixed calculation of MIPS GP relative relocations
30		in case of relocatable output.
	43	* lld now uses the ``sigrie`` instruction as a trap instruction for
	44	MIPS targets.
31	45
32	46	COFF Improvements
33	47	-----------------
34	48
35		* Improved correctness of exporting mangled stdcall symbols.
	49	* PDB GUID is set to hash of PDB contents instead to a random byte
	50	sequence for build reproducibility.
	51
	52	* ``/pdbsourcepath:`` is now also used to make ``"cwd"``, ``"exe"``, ``"pdb"``
	53	in the env block of PDB outputs absolute if they are relative, and to make
	54	paths to obj files referenced in PDB outputs absolute if they are relative.
	55	Together with the previous item, this makes it possible to generate
	56	executables and PDBs that are fully deterministic and independent of the
	57	absolute path to the build directory, so that different machines building
	58	the same code in different directories can produce exactly the same output.
	59
	60	* The following flags have been added: ``/force:multiple``
	61
	62	* lld now can link against import libraries produced by GNU tools.
	63
	64	* lld can create thunks for ARM and ARM64, to allow linking larger images
	65	(over 16 MB for ARM and over 128 MB for ARM64)
	66
	67	* Several speed and memory usage improvements.
	68
	69	* lld now creates debug info for typedefs.
	70
	71	* lld can now link obj files produced by ``cl.exe /Z7 /Yc``.
	72
	73	* lld now understands ``%_PDB%`` and ``%_EXT%`` in ``/pdbaltpath:``.
	74
	75	* Undefined symbols are now printed in demangled form in addition to raw form.
	76
	77	MinGW Improvements
	78	------------------
	79
	80	* lld can now automatically import data variables from DLLs without the
	81	use of the dllimport attribute.
	82
	83	* lld can now use existing normal MinGW sysroots with import libraries and
	84	CRT startup object files for GNU binutils. lld can handle most object
	85	files produced by GCC, and thus works as a drop-in replacement for
	86	ld.bfd in such environments. (There are known issues with linking crtend.o
	87	from GCC in setups with DWARF exceptions though, where object files are
	88	linked in a different order than with GNU ld, inserting a DWARF exception
	89	table terminator too early.)
	90
	91	* lld now supports COFF embedded directives for linking to nondefault
	92	libraries, just like for the normal COFF target.
	93
	94	* Actually generate a codeview build id signature, even if not creating a PDB.
	95	Previously, the ``--build-id`` option did not actually generate a build id
	96	unless ``--pdb`` was specified.
	97
	98	MachO Improvements
	99	------------------
36	100
37		* Completed support for ARM64 relocations.
	101	* Item 1.
38	102
39		* Added support for outputting PDB debug info for MinGW targets.
	103	WebAssembly Improvements
	104	------------------------
40	105
41		* Improved compatibility of output binaries with GNU binutils objcopy/strip.
	106	* Add initial support for creating shared libraries (-shared).
	107	Note: The shared library format is still under active development and may
	108	undergo significant changes in future versions.

	23	Usage
	24	-----
	25
	26	The WebAssembly version of lld is installed as wasm-ld. It shared many
	27	common linker flags with ld.lld but also includes several
	28	WebAssembly-specific options:
	29
	30	.. option:: --no-entry
	31
	32	Don't search for the entry point symbol (by default ``_start``).
	33
	34	.. option:: --export-table
	35
	36	Export the function table to the environment.
	37
	38	.. option:: --import-table
	39
	40	Import the function table from the environment.
	41
	42	.. option:: --export-all
	43
	44	Export all symbols (normally combined with --no-gc-sections)
	45
	46	.. option:: --export-dynamic
	47
	48	When building an executable, export any non-hidden symbols. By default only
	49	the entry point and any symbols marked with --export/--export-all are
	50	exported.
	51
	52	.. option:: --global-base=<value>
	53
	54	Address at which to place global data.
	55
	56	.. option:: --no-merge-data-segments
	57
	58	Disable merging of data segments.
	59
	60	.. option:: --stack-first
	61
	62	Place stack at start of linear memory rather than after data.
	63
	64	.. option:: --compress-relocations
	65
	66	Relocation targets in the code section 5-bytes wide in order to potentially
	67	occomate the largest LEB128 value. This option will cause the linker to
	68	shirnk the code section to remove any padding from the final output. However
	69	because it effects code offset, this option is not comatible with outputing
	70	debug information.
	71
	72	.. option:: --allow-undefined
	73
	74	Allow undefined symbols in linked binary.
	75
	76	.. option:: --import-memory
	77
	78	Import memory from the environment.
	79
	80	.. option:: --initial-memory=<value>
	81
	82	Initial size of the linear memory. Default: static data size.
	83
	84	.. option:: --max-memory=<value>
	85
	86	Maximum size of the linear memory. Default: unlimited.
	87
	88	By default the function table is neither imported nor exported, but defined
	89	for internal use only.
	90
	91	When building shared libraries symbols are exported if they are marked
	92	as ``visibility=default``. When building executables only the entry point is
	93	exported by default. In addition any symbol included on the command line via
	94	``--export`` is also exported.
	95
	96	Since WebAssembly is designed with size in mind the linker defaults to
	97	``--gc-sections`` which means that all unused functions and data segments will
	98	be stripped from the binary.
	99
	100	The symbols which are preserved by default are:
	101
	102	- The entry point (by default ``_start``).
	103	- Any symbol which is to be exported.
	104	- Any symbol transitively referenced by the above.
	105
	106
26	107	Missing features
27	108	----------------
28	109
29		There are several key features that are not yet implement in the WebAssembly
30		ports:
31
32		- COMDAT support. This means that support for C++ is still very limited.
33		- Function stripping. Currently there is no support for ``--gc-sections`` so
34		functions and data from a given object will linked as a unit.
35		- Section start/end symbols. The synthetic symbols that mark the start and
36		of data regions are not yet created in the output file.
	110	- Merging of data section similar to ``SHF_MERGE`` in the ELF world is not
	111	supported.
	112	- No support for creating shared libraries. The spec for shared libraries in
	113	WebAssembly is still in flux:

	1	Missing Key Function
	2	====================
	3
	4	If your build failed with a linker error something like this::
	5
	6	foo.cc:28: error: undefined reference to 'vtable for C'
	7	the vtable symbol may be undefined because the class is missing its key function (see https://lld.llvm.org/missingkeyfunction)
	8
	9	it's likely that your class C has a key function (defined by the ABI as the first
	10	non-pure, non-inline, virtual method), but you haven't actually defined it.
	11
	12	When a class has a key function, the compiler emits the vtable (and some other
	13	things as well) only in the translation unit that defines that key function. Thus,
	14	if you're missing the key function, you'll also be missing the vtable. If no other
	15	function calls your missing method, you won't see any undefined reference errors
	16	for it, but you will see undefined references to the vtable symbol.
	17
	18	When a class has no non-pure, non-inline, virtual methods, there is no key
	19	method, and the compiler is forced to emit the vtable in every translation unit
	20	that references the class. In this case, it is emitted in a COMDAT section,
	21	which allows the linker to eliminate all duplicate copies. This is still
	22	wasteful in terms of object file size and link time, so it's always advisable to
	23	ensure there is at least one eligible method that can serve as the key function.
	24
	25	Here are the most common mistakes that lead to this error:
	26
	27	Failing to define a virtual destructor
	28	--------------------------------------
	29
	30	Say you have a base class declared in a header file::
	31
	32	class B {
	33	public:
	34	B();
	35	virtual ~B();
	36	...
	37	};
	38
	39	Here, ``~B`` is the first non-pure, non-inline, virtual method, so it is the key
	40	method. If you forget to define ``B::~B`` in your source file, the compiler will
	41	not emit the vtable for ``B``, and you'll get an undefined reference to "vtable
	42	for B".
	43
	44	This is just an example of the more general mistake of forgetting to define the
	45	key function, but it's quite common because virtual destructors are likely to be
	46	the first eligible key function and it's easy to forget to implement them. It's
	47	also more likely that you won't have any direct references to the destructor, so
	48	you won't see any undefined reference errors that point directly to the problem.
	49
	50	The solution in this case is to implement the missing method.
	51
	52	Forgetting to declare a virtual method in an abstract class as pure
	53	-------------------------------------------------------------------
	54
	55	Say you have an abstract base class declared in a header file::
	56
	57	class A {
	58	public:
	59	A();
	60	virtual ~A() {}
	61	virtual int foo() = 0;
	62	...
	63	virtual int bar();
	64	...
	65	};
	66
	67	This base class is intended to be abstract, but you forgot to mark one of the
	68	methods pure. Here, ``A::bar``, being non-pure, is nominated as the key function,
	69	and as a result, the vtable for ``A`` is not emitted, because the compiler is
	70	waiting for a translation unit that defines ``A::bar``.
	71
	72	The solution in this case is to add the missing ``= 0`` to the declaration of
	73	``A::bar``.
	74
	75	Key method is defined, but the linker doesn't see it
	76	----------------------------------------------------
	77
	78	It's also possible that you have defined the key function somewhere, but the
	79	object file containing the definition of that method isn't being linked into
	80	your application.
	81
	82	The solution in this case is to check your dependencies to make sure that
	83	the object file or the library file containing the key function is given to
	84	the linker.

	3	When compiling certain forms of templated inline functions, some
	4	versions of GCC (tested with 5.4) produces a weak symbol for the function.
	5	Newer versions of GCC don't do this though.
	6
	7	The bundled object files are an example of that, they can be produced
	8	with test code like this:
	9
	10	$ cat inline-weak.h
	11	class MyClass {
	12	public:
	13	template<typename... _Args> int get(_Args&&... args) {
	14	return a;
	15	}
	16	private:
	17	int a;
	18	};
	19
	20	$ cat inline-weak.cpp

	22
	23	int get(MyClass& a);
	24
	25	int main(int argc, char* argv[]) {
	26	MyClass a;
	27	int ret = a.get();
	28	ret += get(a);
	29	return ret;
	30	}
	31	extern "C" void mainCRTStartup(void) {
	32	main(0, (char**)0);
	33	}
	34	extern "C" void __main(void) {
	35	}
	36
	37	$ cat inline-weak2.cpp
	38	#include "inline-weak.h"
	39
	40	int get(MyClass& a) {
	41	return a.get();
	42	}

	61	0000000000000000 T _ZN7MyClass3getIJEEEiDpOT_
	62
	63	This can't be reproduced by assembling .s files with llvm-mc, since that
	64	always produces a symbol named .weak.<weaksymbol>.default, therefore
	65	the test uses prebuilt object files instead.
	66
	67	In these cases, the undefined weak symbol points to the regular symbol
	68	.weak._ZN7MyClass3getIIEEEiDpOT_.<othersymbol>, where <othersymbol>
	69	varies among the object files that emit the same function. This regular
	70	symbol points to the same location as the comdat function
	71	_ZN7MyClass3getIJEEEiDpOT_.
	72
	73	When linking, the comdat section from the second object file gets
	74	discarded, as it matches the one that already exists. This means that
	75	the uniquely named symbol .weak.<weakname>.<othername> points to a
	76	discarded section chunk.
	77
	78	Previously, this would have triggered adding an Undefined symbol for
	79	this case, which would later break linking. However, also previously,
	80	if the second object file is linked in via a static library, this
	81	leftover symbol is retained as a Lazy symbol, which would make the link
	82	succeed.
