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:``.

		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.

		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	Missing features	107	Missing features

31		112	- No support for creating shared libraries. The spec for shared libraries in

33	- Function stripping. Currently there is no support for ``--gc-sections`` so	114	https://github.com/WebAssembly/tool-conventions/blob/master/DynamicLinking.md
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.

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

21	#include "inline-weak.h"
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	}
43
44	$ x86_64-w64-mingw32-g++ -std=c++11 -c inline-weak.cpp
45	$ x86_64-w64-mingw32-g++ -std=c++11 -c inline-weak2.cpp

60	w _ZN7MyClass3getIIEEEiDpOT_
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.

3	# LLD used to crash when linking against a DSO with an undefined STB_LOCAL
4	# symbol in the global part of the dynamic symbol table (i.e. an STB_LOCAL
5	# symbol with an index >= the sh_info of the dynamic symbol table section). Such
6	# a DSO is very broken, because local symbols should precede all global symbols
7	# in the symbol table, and because having a symbol that's both undefined and
8	# STB_LOCAL is a nonsensical combination. Nevertheless, we should warn on such
9	# input files instead of crashing.
10
11	# We've found actual broken DSOs of this sort in the wild, but for this test, we
12	# created a reduced broken input file. There are no tools capable of producing a
13	# broken DSO of this nature, so instead we created a valid DSO with an undefined
14	# global symbol in the dynamic symbol table and then manually edited the binary
15	# to make that symbol local. The valid DSO was created as follows:
16
17	```
18	% cat undef.s

25	% strip undef.so

28	# (--no-rosegment and stripping are unnecessary; they just produce a smaller
29	# binary)
30
31	# This DSO should only have a single dynamic symbol table entry for foo, and
32	# then we can use a small C program to modify that symbol table entry to be
33	# STB_LOCAL instead of STB_GLOBAL.
