10/// Implementation of Call-Chain Clustering from: Optimizing Function Placement
11/// for Large-Scale Data-Center Applications
12/// https://research.fb.com/wp-content/uploads/2017/01/cgo2017-hfsort-final1.pdf
13///
14/// The goal of this algorithm is to improve runtime performance of the final
15/// executable by arranging code sections such that page table and i-cache
16/// misses are minimized.
17///
18/// Definitions:
19/// * Cluster
20/// * An ordered list of input sections which are layed out as a unit. At the
21/// beginning of the algorithm each input section has its own cluster and
22/// the weight of the cluster is the sum of the weight of all incomming
23/// edges.
24/// * Call-Chain Clustering (C³) Heuristic
25/// * Defines when and how clusters are combined. Pick the highest weighted
26/// input section then add it to its most likely predecessor if it wouldn't
27/// penalize it too much.
28/// * Density
29/// * The weight of the cluster divided by the size of the cluster. This is a
30/// proxy for the ammount of execution time spent per byte of the cluster.
31///
32/// It does so given a call graph profile by the following:
33/// * Build a weighted call graph from the call graph profile
34/// * Sort input sections by weight
35/// * For each input section starting with the highest weight
36/// * Find its most likely predecessor cluster
37/// * Check if the combined cluster would be too large, or would have too low
38/// a density.
39/// * If not, then combine the clusters.
40/// * Sort non-empty clusters by density
41///

329 // Do extra check for --warn-backrefs.
330 //
331 // --warn-backrefs is an option to prevent an undefined reference from
332 // fetching an archive member written earlier in the command line. It can be
333 // used to keep compatibility with GNU linkers to some degree.
334 // I'll explain the feature and why you may find it useful in this comment.
335 //
336 // lld's symbol resolution semantics is more relaxed than traditional Unix
337 // linkers. For example,
338 //
339 // ld.lld foo.a bar.o
340 //
341 // succeeds even if bar.o contains an undefined symbol that has to be
342 // resolved by some object file in foo.a. Traditional Unix linkers don't
343 // allow this kind of backward reference, as they visit each file only once
344 // from left to right in the command line while resolving all undefined
345 // symbols at the moment of visiting.
346 //
347 // In the above case, since there's no undefined symbol when a linker visits
348 // foo.a, no files are pulled out from foo.a, and because the linker forgets
349 // about foo.a after visiting, it can't resolve undefined symbols in bar.o
350 // that could have been resolved otherwise.
351 //
352 // That lld accepts more relaxed form means that (besides it'd make more
353 // sense) you can accidentally write a command line or a build file that
354 // works only with lld, even if you have a plan to distribute it to wider
355 // users who may be using GNU linkers. With --warn-backrefs, you can detect
356 // a library order that doesn't work with other Unix linkers.
357 //
358 // The option is also useful to detect cyclic dependencies between static
359 // archives. Again, lld accepts
360 //
361 // ld.lld foo.a bar.a
362 //
363 // even if foo.a and bar.a depend on each other. With --warn-backrefs, it is
364 // handled as an error.
365 //
366 // Here is how the option works. We assign a group ID to each file. A file
367 // with a smaller group ID can pull out object files from an archive file
368 // with an equal or greater group ID. Otherwise, it is a reverse dependency
369 // and an error.
370 //
371 // A file outside --{start,end}-group gets a fresh ID when instantiated. All
372 // files within the same --{start,end}-group get the same group ID. E.g.
373 //
374 // ld.lld A B --start-group C D --end-group E
375 //
376 // A forms group 0. B form group 1. C and D (including their member object
377 // files) form group 2. E forms group 3. I think that you can see how this
378 // group assignment rule simulates the traditional linker's semantics.

19ELF Improvements24ELF Improvements
20----------------25----------------
2126
22* A lot of bugs and compatibility issues have been identified and fixed as a27* Item 1.
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``
7328
74COFF Improvements29COFF Improvements
75-----------------30-----------------
7631
77* A GNU ld style frontend for the COFF linker has been added for MinGW.32* Item 1.
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.
9433
95WebAssembly Improvements34MachO Improvements
96------------------------35------------------
9736
98* Initial version of WebAssembly support has landed. You can invoke the37* Item 1.

514.Sh IMPLEMENTATION NOTES
515.Nm Ap s
516handing of archive files (those with a
517.Pa .a
518file extension) is different from traditional linkers used on Unix-like
519systems.
520.Pp
521Traditional linkers maintain a set of undefined symbols during linking.
522The linker processes each file in the order in which it appears on the
523command line, until the set of undefined symbols becomes empty.
524An object file is linked into the output object when it is encountered,
525with its undefined symbols added to the set.
526Upon encountering an archive file a traditional linker searches the objects
527contained therein, and processes those that satisfy symbols in the unresolved
528set.
529.Pp
530Handling mutually dependent archives may be awkward when using a traditional
531linker.
532Archive files may have to be specified multiple times, or the special command
533line options
534.Fl -start-group
535and
536.Fl -end-group
537may be used to have the linker loop over the files in the group until no new
538symbols are added to the set.
539.Pp
540.Nm
541records all symbols found in objects and archives as it iterates over
542command line arguments.
543When
544.Nm
545encounters an undefined symbol that can be resolved by an object file
546contained in a previously processed archive file, it immediately extracts
547and links it into the output object.
548.Pp
549With certain archive inputs
550.Nm
551may produce different results compared to traditional linkers.
552In practice, large bodies of third party software have been linked with
553.Nm
554without material issues.
555.Pp
556The
557.Fl -warn-backrefs
558option may be used to identify a linker invocation that may be incompatible
559with traditional Unix-like linker behavior.

7//7//
8//===----------------------------------------------------------------------===//8//===----------------------------------------------------------------------===//
9//9//
10// In LLD, we have three levels of errors: fatal, error or warn.10// We designed lld's error handlers with the following goals in mind:
11//11//
12// Fatal makes the program exit immediately with an error message.12// - Errors can occur at any place where we handle user input, but we don't
13// You shouldn't use it except for reporting a corrupted input file.13// want them to affect the normal execution path too much. Ideally,
14// handling errors should be as simple as reporting them and exit (but
15// without actually doing exit).
14//16//
15// Error prints out an error message and increment a global variable17// In particular, the design to wrap all functions that could fail with
16// ErrorCount to record the fact that we met an error condition. It does18// ErrorOr<T> is rejected because otherwise we would have to wrap a large
17// not exit, so it is safe for a lld-as-a-library use case. It is generally19// number of functions in lld with ErrorOr. With that approach, if some
18// useful because it can report more than one error in a single run.20// function F can fail, not only F but all functions that transitively call
21// F have to be wrapped with ErrorOr. That seemed too much.
19//22//
20// Warn doesn't do anything but printing out a given message.23// - Finding only one error at a time is not sufficient. We want to find as
24// many errors as possible with one execution of the linker. That means the
25// linker needs to keep running after a first error and give up at some
26// checkpoint (beyond which it would find cascading, false errors caused by
27// the previous errors).
21//28//
22// It is not recommended to use llvm::outs() or llvm::errs() directly29// - We want a simple interface to report errors. Unlike Clang, the data we
23// in LLD because they are not thread-safe. The functions declared in30// handle is compiled binary, so we don't need an error reporting mechanism
24// this file are mutually excluded, so you want to use them instead.31// that's as sophisticated as the one that Clang has.
32//
33// The current lld's error handling mechanism is simple:
34//
35// - When you find an error, report it using error() and continue as far as
36// you can. An internal error counter is incremented by one every time you
37// call error().
38//
39// A common idiom to handle an error is calling error() and then returning
40// a reasonable default value. For example, if your function handles a
41// user-supplied alignment value, and if you find an invalid alignment
42// (e.g. 17 which is not 2^n), you may report it using error() and continue
43// as if it were alignment 1 (which is the simplest reasonable value).
44//
45// Note that you should not continue with an invalid value; that breaks the
46// internal consistency. You need to maintain all variables have some sane
47// value even after an error occurred. So, when you have to continue with
48// some value, always use a dummy value.
49//
50// - Find a reasonable checkpoint at where you want to stop the linker, and
51// add code to return from the function if errorCount() > 0. In most cases,
52// a checkpoint already exists, so you don't need to do anything for this.
53//
54// This interface satisfies all the goals that we mentioned above.
55//
56// You should never call fatal() except for reporting a corrupted input file.
57// fatal() immediately terminates the linker, so the function is not desirable
58// if you are using lld as a subroutine in other program, and with that you
59// can find only one error at a time.
60//
61// warn() doesn't do anything but printing out a given message.
62//
63// It is not recommended to use llvm::outs() or llvm::errs() directly in lld
64// because they are not thread-safe. The functions declared in this file are
65// thread-safe.

1This test verifies that we produce PDBs compatible with MSVC in various ways.
2We check in a cl-generated object file, PDB, and original source which serve
3as the "baseline" for us to measure against. Then we link the same object
4file with LLD and compare the two PDBs. Since the baseline object file and
5PDB are already checked in, we just run LLD on the object file.

7# Note: how the layout is done:
8# we need to layout 2 segments, each contains sections:
9# seg1: .data .dynamic
10# seg2: .dynsym .dynstr .text .hash
11# for each segment, we start from the first section, regardless
12# whether it is an orphan or not (sections that are not listed in the
13# linkerscript are orphans):
14# for seg1, we assign address: .data(0x4000), .dynamic(0x4008)
15# for seg2, we assign address: .dynsym(0x2000), .dynstr(0x2018) ...
16# .dynsym is not an orphan, so we take address from script, we assign
17# .dynstr current address cursor, which is the end # of .dynsym and so
18# on for later sections.
19
20# Also note, it is absolutely *illegal* to have section addresses of
21# the same segment in none-increasing order, authors of linker scripts
22# must take responsibility to make sure this does not happen.
