	1061	// Thunk Implementation
	1062	//
	1063	// Thunks (sometimes called stubs, veneers or branch islands) are small pieces
	1064	// of code that the linker inserts inbetween a caller and a callee. The thunks
	1065	// are added at link time rather than compile time as the decision on whether
	1066	// a thunk is needed, such as the caller and callee being out of range, can only
	1067	// be made at link time.
	1068	//
	1069	// It is straightforward to tell given the current state of the program when a
	1070	// thunk is needed for a particular call. The more difficult part is that
	1071	// the thunk needs to be placed in the program such that the caller can reach
	1072	// the thunk and the thunk can reach the callee; furthermore, adding thunks to
	1073	// the program alters addresses, which can mean more thunks etc.
	1074	//
	1075	// In lld we have a synthetic ThunkSection that can hold many Thunks.
	1076	// The decision to have a ThunkSection act as a container means that we can
	1077	// more easily handle the most common case of a single block of contiguous
	1078	// Thunks by inserting just a single ThunkSection.
	1079	//
	1080	// The implementation of Thunks in lld is split across these areas
	1081	// Relocations.cpp : Framework for creating and placing thunks
	1082	// Thunks.cpp : The code generated for each supported thunk
	1083	// Target.cpp : Target specific hooks that the framework uses to decide when
	1084	// a thunk is used
	1085	// Synthetic.cpp : Implementation of ThunkSection
	1086	// Writer.cpp : Iteratively call framework until no more Thunks added
	1087	//
	1088	// Thunk placement requirements:
	1089	// Mips LA25 thunks. These must be placed immediately before the callee section
	1090	// We can assume that the caller is in range of the Thunk. These are modelled
	1091	// by Thunks that return the section they must precede with
	1092	// getTargetInputSection().
	1093	//
	1094	// ARM interworking and range extension thunks. These thunks must be placed
	1095	// within range of the caller. All implemented ARM thunks can always reach the
	1096	// callee as they use an indirect jump via a register that has no range
	1097	// restrictions.
	1098	//
	1099	// Thunk placement algorithm:
	1100	// For Mips LA25 ThunkSections; the placement is explicit, it has to be before
	1101	// getTargetInputSection().
	1102	//
	1103	// For thunks that must be placed within range of the caller there are many
	1104	// possible choices given that the maximum range from the caller is usually
	1105	// much larger than the average InputSection size. Desirable properties include:
	1106	// - Maximize reuse of thunks by multiple callers
	1107	// - Minimize number of ThunkSections to simplify insertion
	1108	// - Handle impact of already added Thunks on addresses
	1109	// - Simple to understand and implement
	1110	//
	1111	// In lld for the first pass, we pre-create one or more ThunkSections per
	1112	// InputSectionDescription at Target specific intervals. A ThunkSection is
	1113	// placed so that the estimated end of the ThunkSection is within range of the
	1114	// start of the InputSectionDescription or the previous ThunkSection. For
	1115	// example:
	1116	// InputSectionDescription
	1117	// Section 0
	1118	// ...
	1119	// Section N
	1120	// ThunkSection 0
	1121	// Section N + 1
	1122	// ...
	1123	// Section N + K
	1124	// Thunk Section 1
	1125	//
	1126	// The intention is that we can add a Thunk to a ThunkSection that is well
	1127	// spaced enough to service a number of callers without having to do a lot
	1128	// of work. An important principle is that it is not an error if a Thunk cannot
	1129	// be placed in a pre-created ThunkSection; when this happens we create a new
	1130	// ThunkSection placed next to the caller. This allows us to handle the vast
	1131	// majority of thunks simply, but also handle rare cases where the branch range
	1132	// is smaller than the target specific spacing.
	1133	//
	1134	// The algorithm is expected to create all the thunks that are needed in a
	1135	// single pass, with a small number of programs needing a second pass due to
	1136	// the insertion of thunks in the first pass increasing the offset between
	1137	// callers and callees that were only just in range.
	1138	//
	1139	// A consequence of allowing new ThunkSections to be created outside of the
	1140	// pre-created ThunkSections is that in rare cases calls to Thunks that were in
	1141	// range in pass K, are out of range in some pass > K due to the insertion of
	1142	// more Thunks in between the caller and callee. When this happens we retarget
	1143	// the relocation back to the original target and create another Thunk.
	1144
	1145	// Remove ThunkSections that are empty, this should only be the initial set
	1146	// precreated on pass 0.
	1147

9		//
10		// LLD supports threads to distribute workloads to multiple cores. Using
11		// multicore is most effective when more than one core are idle. At the
12		// last step of a build, it is often the case that a linker is the only
13		// active process on a computer. So, we are naturally interested in using
14		// threads wisely to reduce latency to deliver results to users.
15		//
16		// That said, we don't want to do "too clever" things using threads.
17		// Complex multi-threaded algorithms are sometimes extremely hard to
18		// reason about and can easily mess up the entire design.
19		//
20		// Fortunately, when a linker links large programs (when the link time is
21		// most critical), it spends most of the time to work on massive number of
22		// small pieces of data of the same kind, and there are opportunities for
23		// large parallelism there. Here are examples:
24		//
25		// - We have hundreds of thousands of input sections that need to be
26		// copied to a result file at the last step of link. Once we fix a file
27		// layout, each section can be copied to its destination and its
28		// relocations can be applied independently.
29		//
30		// - We have tens of millions of small strings when constructing a
31		// mergeable string section.
32		//
33		// For the cases such as the former, we can just use parallel_for_each
34		// instead of std::for_each (or a plain for loop). Because tasks are
35		// completely independent from each other, we can run them in parallel
36		// without any coordination between them. That's very easy to understand
37		// and reason about.
38		//
39		// For the cases such as the latter, we can use parallel algorithms to
40		// deal with massive data. We have to write code for a tailored algorithm
41		// for each problem, but the complexity of multi-threading is isolated in
42		// a single pass and doesn't affect the linker's overall design.
43		//
44		// The above approach seems to be working fairly well. As an example, when
45		// linking Chromium (output size 1.6 GB), using 4 cores reduces latency to
46		// 75% compared to single core (from 12.66 seconds to 9.55 seconds) on my
47		// Ivy Bridge Xeon 2.8 GHz machine. Using 40 cores reduces it to 63% (from
48		// 12.66 seconds to 7.95 seconds). Because of the Amdahl's law, the
49		// speedup is not linear, but as you add more cores, it gets faster.
50		//
51		// On a final note, if you are trying to optimize, keep the axiom "don't
52		// guess, measure!" in mind. Some important passes of the linker are not
53		// that slow. For example, resolving all symbols is not a very heavy pass,
54		// although it would be very hard to parallelize it. You want to first
55		// identify a slow pass and then optimize it.

159		* Symbol
	162	There's only one Symbol instance for each unique symbol name. This uniqueness

160	166
161		A Symbol is a container for a SymbolBody. There's only one Symbol for each
162		unique symbol name (this uniqueness is guaranteed by the symbol table).
163		Each global symbol has only one SymbolBody at any one time, which is
164		the SymbolBody stored within a memory region of the Symbol large enough
165		to store any SymbolBody.
166
167		As the resolver reads symbols from input files, it replaces the Symbol's
168		SymbolBody with the "best" SymbolBody for its symbol name by constructing
169		the new SymbolBody in place on top of the existing SymbolBody. For example,
170		if the resolver is given a defined symbol, and the SymbolBody with its name
171		is undefined, it will construct a Defined SymbolBody over the Undefined
172		SymbolBody.
173
174		This means that each SymbolBody pointer always points to the best SymbolBody,
175		and it is possible to get from a SymbolBody to a Symbol, or vice versa,
176		by adding or subtracting a fixed offset. This memory layout helps reduce
177		the cache miss rate through high locality and a small number of required
178		pointer indirections.
	167	The above mechanism allows you to use pointers to Symbols as a very cheap way
	168	to access name resolution results. Assume for example that you have a pointer
	169	to an undefined symbol before name resolution. If the symbol is resolved to a
	170	defined symbol by the resolver, the pointer will "automatically" point to the
	171	defined symbol, because the undefined symbol the pointer pointed to will have

11		lld is a linker from the LLVM project. It supports ELF (Unix), COFF (Windows)
12		and Mach-O (macOS), and it is generally faster than the GNU bfd or gold linkers
13		or the MSVC linker.
14
15		lld is designed to be a drop-in replacement for the system linkers, so that
16		users don't need to change their build systems other than swapping the linker
17		command.

25	19	ELF Improvements
26	20	----------------
27	21
28		* First and foremost, a lot of compatibility issues and bugs have been fixed.
29		Linker script support has significantly improved. As a result, we believe you
30		are very likely to be able to link your programs with lld without experiencing
31		any problem now.
32
33		* Error message format has changed in order to improve readability.
34		Traditionally, linker's error messages are concise and arguably too terse.
35		This is an example of lld 4.0.0's error message (they are actually in one line)::
36
37		/ssd/clang/bin/ld.lld: error: /ssd/llvm-project/lld/ELF/Writer.cpp:207:
38		undefined symbol 'lld::elf::EhFrameSection::addSection()'
39
40		It is not easy to read because too much information is packed into a single line
41		and the embedded text, particularly a symbol name, is sometimes too long.
42		In lld 5.0.0, we use more vertical space to print out error messages in a more
43		structured manner like this::
44
45		bin/ld.lld: error: undefined symbol: lld::elf::EhFrameSection::addSection()
46		>>> Referenced by Writer.cpp:207 (/ssd/llvm-project/lld/ELF/Writer.cpp:207)
47		>>> Writer.cpp.o in archive lib/liblldELF.a
48
49		As a bonus, the new error message contains source code location of the error
50		if it is available from debug info.
51
52		* ``./configure`` scripts generated by GNU autoconf determines whether a linker
53		supports modern GNU-compatible features or not by searching for "GNU" in the
54		``--help`` message. To be compatible with the scripts, we decided to add a
55		string "(compatible with GNU linkers)" to our ``--help`` message. This is a
56		hack, but just like the web browser's User-Agent string (which everyone still
57		claim they are "Mozilla/5.0"), we had no choice other than doing this to claim
58		that we accept GNU-compatible options.
59
60		* The ``-Map`` option is added. The option is to make the linker to print out how
61		input files are mapped to the output file. Here is an example::
62
63		Address Size Align Out In Symbol
64		00000000016d84d8 00000000008f8f50 8 .eh_frame
65		00000000016d84d8 00000000008f8f50 8 <internal>:(.eh_frame)
66		0000000001fd2000 00000000034b3bd0 16 .text
67		0000000001fd2000 000000000000002a 1 /usr/lib/x86_64-linux-gnu/crt1.o:(.text)
68		0000000001fd2000 0000000000000000 0 _start
69		0000000001fd202a 0000000000000000 1 /usr/lib/x86_64-linux-gnu/crti.o:(.text)
70		0000000001fd2030 00000000000000bd 16 /usr/lib/gcc/x86_64-linux-gnu/4.8/crtbegin.o:(.text)
71		0000000001fd2030 0000000000000000 0 deregister_tm_clones
72		0000000001fd2060 0000000000000000 0 register_tm_clones
73
74		This format is not the same as GNU linkers as our linker internal data
75		structure is different from them but contains the same amount of information
76		and should be more readable than their outputs.
77
78		As with other lld features, the ``-Map`` option is designed with speed in mind.
79		The option would generate a hundred megabyte text file if you link a large
80		program with it. lld can usually do that in a few seconds, and it is generally
81		a few times faster than the GNU gold's ``-Map`` option.
82
83		* lld's ``--gdb-index`` option used to be slow, but we sped it up so that it is
84		at least as fast as the GNU gold.
85
86		* Some nonstandard relocations, such as R_X86_64_8 or R_X86_64_16, are supported.
87		They are not used for 32/64-bit applications, but some 16-bit bootloaders need
88		them.
89
90		* Paddings in executable text sections are now filled with trap instructions
91		(such as INT3) instead of being left as null bytes. This change improves
92		disassembler outputs because it now prints out trap instructions instead of
93		trying to decode 0x00 as an instruction. It also makes debugging of some type
94		of program easier because when the control reaches a padding, the program

105		Contributors to lld 5.0
106		=======================
	22	* A lot of bugs and compatibility issues have been identified and fixed as a
	23	result of people using lld 5.0 as a standard system linker. In particular,
	24	linker script and version script support has significantly improved that
	25	it should be able to handle almost all scripts.
	26
	27	* A mitigation for Spectre v2 has been implemented. If you pass ``-z
	28	retpolineplt``, lld uses RET instruction instead of JMP instruction in PLT.
	29	The option is available for x86 and x86-64.
	30
	31	* Identical Code Folding (ICF) now de-duplicates .eh_frame entries, so lld now
	32	generates slightly smaller outputs than before when you pass ``--icf=all``.
	33
	34	* Analysis for ``--as-needed`` is now done after garbage collection. If garbage
	35	collector eliminates all sections that use some library, that library is
	36	eliminated from DT_NEEDED tags. Previously, the analysis ran before garbage
	37	collection.
	38
	39	* Size of code segment is now always rounded up to page size to make sure that
	40	unused bytes at end of code segment is filled with trap instructions (such
	41	as INT3) instead of zeros.
	42
	43	* lld is now able to generate Android-style compact dynamic relocation table.
	44	You can turn on the feature by passing ``--pack-dyn-relocs=android``.
	45
	46	* Debug information is used in more cases when reporting errors.
	47
	48	* ``--gdb-index`` gets faster than before.
	49
	50	* String merging is now multi-threaded, which makes ``-O2`` faster.
	51
	52	* ``--hash-style=both`` is now default instead of ``--hash-style=sysv`` to
	53	match the behavior of recent versions of GNU linkers.
	54
	55	* ARM PLT entries automatically use short or long variants.
	56
	57	* lld can now identify and patch a code sequence that triggers AArch64 errata 843419.
	58	Add ``--fix-cortex-a53-843419`` to enable the feature.
	59
	60	* lld can now generate thunks for out of range thunks.
	61
	62	* MIPS port now generates all output dynamic relocations using Elf_Rel format only.
	63
	64	* Added handling of the R_MIPS_26 relocation in case of N32/N64 ABIs and
	65	generating proper PLT entries.
	66
	67	* The following options have been added: ``--icf=none`` ``-z muldefs``
	68	``--plugin-opt`` ``--no-eh-frame-hdr`` ``--no-gdb-index``
	69	``--orphan-handling={place,discard,warn,error}``
	70	``--pack-dyn-relocs={none,android}`` ``--no-omagic``
	71	``--no-print-gc-sections`` ``--ignore-function-address-equality`` ``-z
	72	retpolineplt`` ``--print-icf-sections`` ``--no-pie``
	73
	74	COFF Improvements
	75	-----------------
	76
	77	* A GNU ld style frontend for the COFF linker has been added for MinGW.
	78	In MinGW environments, the linker is invoked with GNU ld style parameters;
	79	which lld previously only supported when used as an ELF linker. When
	80	a PE/COFF target is chosen, those parameters are rewritten into the
	81	lld-link style parameters and the COFF linker is invoked instead.
	82
	83	* Initial support for the ARM64 architecture has been added.
	84
	85	* New ``--version`` flag.
	86
	87	* Significantly improved support for writing PDB Files.
	88
	89	* New ``--rsp-quoting`` flag, like ``clang-cl``.
	90
	91	* ``/manifestuac:no`` no longer incorrectly disables ``/manifestdependency:``.
	92
	93	* Only write ``.manifest`` files if ``/manifest`` is passed.

	1	WebAssembly lld port
	2	====================
	3
	4	Note: The WebAssembly port is still a work in progress and is be lacking
	5	certain features.
	6
	7	The WebAssembly version of lld takes WebAssembly binaries as inputs and produces
	8	a WebAssembly binary as its output. For the most part this port tried to mimic
	9	the behaviour of traditional ELF linkers and specifically the ELF lld port.
	10	Where possible that command line flags and the semantics should be the same.
	11
	12
	13	Object file format
	14	------------------
	15
	16	The format the input object files that lld expects is specified as part of the
	17	the WebAssembly tool conventions
	18	https://github.com/WebAssembly/tool-conventions/blob/master/Linking.md.
	19
	20	This is object format that the llvm will produce when run with the
	21	``wasm32-unknown-unknown-wasm`` target. To build llvm with WebAssembly support
	22	currently requires enabling the experimental backed using
	23	``-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=WebAssembly``.
	24
	25
	26	Missing features
	27	----------------
	28
	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.

58	58	~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
59	59
60		In order to build the documentation, all you should need to do is change to the
61		``docs`` directory and invoke make as follows::
62
63		$ cd path/to/project/docs
64		$ make html
65
66		Note that on Windows there is a ``make.bat`` command in the docs directory which
67		supplies the same interface as the ``Makefile``.
68
69		That command will invoke ``sphinx-build`` with the appropriate options for the
70		project, and generate the HTML documentation in a ``_build`` subdirectory. You
71		can browse it starting from the index page by visiting
72		``_build/html/index.html``.
73
74		Sphinx supports a wide variety of generation formats (including LaTeX, man
75		pages, and plain text). The ``Makefile`` includes a number of convenience
76		targets for invoking ``sphinx-build`` appropriately, the common ones are:
77
78		make html
79		Generate the HTML output.
80
81		make latexpdf
82		Generate LaTeX documentation and convert to a PDF.
83
84		make man
85		Generate man pages.
	60	In order to build the documentation need to add ``-DLLVM_ENABLE_SPHINX=ON`` to
	61	your ``cmake`` command. Once you do this you can build the docs using
	62	``docs-lld-html`` build (``ninja`` or ``make``) target.
86	63
	64	That build target will invoke ``sphinx-build`` with the appropriate options for
	65	the project, and generate the HTML documentation in a ``tools/lld/docs/html``

	10	// LLD supports threads to distribute workloads to multiple cores. Using
	11	// multicore is most effective when more than one core are idle. At the
	12	// last step of a build, it is often the case that a linker is the only
	13	// active process on a computer. So, we are naturally interested in using
	14	// threads wisely to reduce latency to deliver results to users.
	15	//
	16	// That said, we don't want to do "too clever" things using threads.
	17	// Complex multi-threaded algorithms are sometimes extremely hard to
	18	// reason about and can easily mess up the entire design.
	19	//
	20	// Fortunately, when a linker links large programs (when the link time is
	21	// most critical), it spends most of the time to work on massive number of
	22	// small pieces of data of the same kind, and there are opportunities for
	23	// large parallelism there. Here are examples:
	24	//
	25	// - We have hundreds of thousands of input sections that need to be
	26	// copied to a result file at the last step of link. Once we fix a file
	27	// layout, each section can be copied to its destination and its
	28	// relocations can be applied independently.
	29	//
	30	// - We have tens of millions of small strings when constructing a
	31	// mergeable string section.
	32	//
	33	// For the cases such as the former, we can just use parallelForEach
	34	// instead of std::for_each (or a plain for loop). Because tasks are
	35	// completely independent from each other, we can run them in parallel
	36	// without any coordination between them. That's very easy to understand
	37	// and reason about.
	38	//
	39	// For the cases such as the latter, we can use parallel algorithms to
	40	// deal with massive data. We have to write code for a tailored algorithm
	41	// for each problem, but the complexity of multi-threading is isolated in
	42	// a single pass and doesn't affect the linker's overall design.
	43	//
	44	// The above approach seems to be working fairly well. As an example, when
	45	// linking Chromium (output size 1.6 GB), using 4 cores reduces latency to
	46	// 75% compared to single core (from 12.66 seconds to 9.55 seconds) on my
	47	// Ivy Bridge Xeon 2.8 GHz machine. Using 40 cores reduces it to 63% (from
	48	// 12.66 seconds to 7.95 seconds). Because of the Amdahl's law, the
	49	// speedup is not linear, but as you add more cores, it gets faster.
	50	//
	51	// On a final note, if you are trying to optimize, keep the axiom "don't
	52	// guess, measure!" in mind. Some important passes of the linker are not
	53	// that slow. For example, resolving all symbols is not a very heavy pass,
	54	// although it would be very hard to parallelize it. You want to first
	55	// identify a slow pass and then optimize it.
