19	ELF Improvements	21	ELF Improvements
20	----------------	22	----------------
21		23
22	* lld is now able to overcome MIPS GOT entries number limitation	24	* lld now supports RISC-V. (`r339364
23	and generate multi-GOT if necessary.	25	<https://reviews.llvm.org/rL339364>`_)
		26
		27	* Default image base address has changed from 65536 to 2 MiB for i386
		28	and 4 MiB for AArch64 to make lld-generated executables work better
		29	with automatic superpage promotion. FreeBSD can promote contiguous
		30	non-superpages to a superpage if they are aligned to the superpage
		31	size. (`r342746 <https://reviews.llvm.org/rL342746>`_)
		32
		33	* lld now attempts to place a ``.note`` segment in the first page of a
		34	generated file, so that you can find some important information
		35	(``.note.gnu.build-id`` in particular) in a core file even if a core
		36	file is truncated by ulimit.
		37	(`r349524 <https://reviews.llvm.org/rL349524>`_)
		38
		39	* lld now reports an error if ``_GLOBAL_OFFSET_TABLE_`` symbol is
		40	defined by an input object file, as the symbol is supposed to be
		41	synthesized by the linker.
		42	(`r347854 <https://reviews.llvm.org/rL347854>`_)
		43
		44	* lld/Hexagon can now link Linux kernel and musl libc for Qualcomm
		45	Hexagon ISA.
24		46
25	* lld is now able to produce MIPS position-independent executable (PIE).	47	* Initial MSP430 ISA support has landed.
26		48
27	* Fixed MIPS TLS GOT entries for local symbols in shared libraries.	49	* lld now uses the ``sigrie`` instruction as a trap instruction for
		50	MIPS targets.
28		51
29	* Fixed calculation of MIPS GP relative relocations	52	* lld now creates a TLS segment for AArch64 with a slightly larger
30	in case of relocatable output.	53	alignment requirement, so that the loader makes a few bytes room
		54	before each TLS segment at runtime. The aim of this change is to
		55	make room to accomodate nonstandard Android TLS slots while keeping
		56	the compatibility with the standard AArch64 ABI.
		57	(`r350681 <https://reviews.llvm.org/rL350681>`_)
		58
		59	* The following flags have been added: ``--call-graph-profile``,
		60	``--no-call-graph-profile``, ``--warn-ifunc-textrel``,
		61	``-z interpose``, ``-z global``, ``-z nodefaultlib``
31		62
32	COFF Improvements	63	COFF Improvements
33	-----------------	64	-----------------
34		65
35	* Improved correctness of exporting mangled stdcall symbols.	66	* PDB GUID is set to hash of PDB contents instead to a random byte
		67	sequence for build reproducibility.
		68
		69	* ``/pdbsourcepath:`` is now also used to make ``"cwd"``, ``"exe"``, ``"pdb"``
		70	in the env block of PDB outputs absolute if they are relative, and to make
		71	paths to obj files referenced in PDB outputs absolute if they are relative.
		72	Together with the previous item, this makes it possible to generate
		73	executables and PDBs that are fully deterministic and independent of the
		74	absolute path to the build directory, so that different machines building
		75	the same code in different directories can produce exactly the same output.
		76
		77	* The following flags have been added: ``/force:multiple``
		78
		79	* lld now can link against import libraries produced by GNU tools.
		80
		81	* lld can create thunks for ARM and ARM64, to allow linking larger images
		82	(over 16 MB for ARM and over 128 MB for ARM64)
		83
		84	* Several speed and memory usage improvements.
		85
		86	* lld now creates debug info for typedefs.
		87
		88	* lld can now link obj files produced by ``cl.exe /Z7 /Yc``.
		89
		90	* lld now understands ``%_PDB%`` and ``%_EXT%`` in ``/pdbaltpath:``.
		91
		92	* Undefined symbols are now printed in demangled form in addition to raw form.
		93
		94	MinGW Improvements
		95	------------------
		96
		97	* lld can now automatically import data variables from DLLs without the
		98	use of the dllimport attribute.
		99
		100	* lld can now use existing normal MinGW sysroots with import libraries and
		101	CRT startup object files for GNU binutils. lld can handle most object
		102	files produced by GCC, and thus works as a drop-in replacement for
		103	ld.bfd in such environments. (There are known issues with linking crtend.o
		104	from GCC in setups with DWARF exceptions though, where object files are
		105	linked in a different order than with GNU ld, inserting a DWARF exception
		106	table terminator too early.)
		107
		108	* lld now supports COFF embedded directives for linking to nondefault
		109	libraries, just like for the normal COFF target.
36		110
37	* Completed support for ARM64 relocations.	111	* Actually generate a codeview build id signature, even if not creating a PDB.
		112	Previously, the ``--build-id`` option did not actually generate a build id
		113	unless ``--pdb`` was specified.
38		114
39	* Added support for outputting PDB debug info for MinGW targets.	115	WebAssembly Improvements
		116	------------------------
40		117
41	* Improved compatibility of output binaries with GNU binutils objcopy/strip.	118	* Add initial support for creating shared libraries (-shared).
		119	Note: The shared library format is still under active development and may
		120	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>

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.

4	* The yaml reader/writer interfaces should be changed to return
5	an explanatory string if there is an error. The existing error_code
6	abstraction only works for returning low level OS errors. It does not
7	work for describing formatting issues.
8
9	* We need to add more attributes to File. In particular, we need cpu
10	and OS information (like target triples). We should also provide explicit
11	support for `LLVM IR module flags metadata`__.

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

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

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.
