Vy Nguyen 3afa2151f8 [llvm-ar][nfc] Reword help message to be less ambiguous on what p and t do.
The current help msg isn't super clear on whether t prints the content of the files or just the list of files.
(I'd certainly thought it'd print the list of files, and accidentally had a bunch of "gargabe" printed to my terminal).
Similarly, t sounded like it'd do what p actually did.

This is a mechanical change. This actually also renames the

this doesn't break building of the rest of the monorepo.

In future patches I will be setting the IsText parameter frequently so I will refactor the args to be in the following order. I have removed the FileSize parameter because it is never used.

  getFile(const Twine &Filename, bool IsText = false,
          bool RequiresNullTerminator = true, bool IsVolatile = false);

  static ErrorOr<std::unique_ptr<MemoryBuffer>>
  getFileOrSTDIN(const Twine &Filename, bool IsText = false,
                 bool RequiresNullTerminator = true);

 static ErrorOr<std::unique_ptr<MB>>
 getFileAux(const Twine &Filename, uint64_t MapSize, uint64_t Offset,
            bool IsText, bool RequiresNullTerminator, bool IsVolatile);

  static ErrorOr<std::unique_ptr<WritableMemoryBuffer>>

serge-sans-paille 9218ff50f9 llvmbuildectomy - replace llvm-build by plain cmake
No longer rely on an external tool to build the llvm component layout.

Instead, leverage the existing `add_llvm_componentlibrary` cmake function and
introduce `add_llvm_component_group` to accurately describe component behavior.

These function store extra properties in the created targets. These properties
are processed once all components are defined to resolve library dependencies
and produce the header expected by llvm-config.

kind based on the target triple.

This specifically addresses https://github.com/android/ndk/issues/1209

I have been trying to build CheriBSD (a fork for FreeBSD for the CHERI

Daniel Sanders 3e4acaabb9 Break false dependencies on target libraries
Summary:
For the most part this consists of replacing ${LLVM_TARGETS_TO_BUILD} with
some combination of AllTargets* so that they depend on specific components
of a target backend rather than all of it. The overall effect of this is
that, for example, tools like opt no longer falsely depend on the
disassembler, while tools like llvm-ar no longer depend on the code
generator.

There's a couple quirks to point out here:
* AllTargetsCodeGens is a bit more prevalent than expected. Tools like dsymutil
  seem to need it which I was surprised by.
* llvm-xray linked to all the backends but doesn't seem to need any of them.
  It builds and passes the tests so that seems to be correct.
* I left gold out as it's not built when binutils is not available so I'm
  unable to test it

foo
foo
$ llvm-ar x archive.a
-> Writes foo twice, overwriting it the second time :( :(
$ llvm-ar xN 1 archive.a foo && mv foo foo.1
$ llvm-ar xN 2 archive.a foo && mv foo foo.2
-> Write foo twice, renaming it in between invocations to preserve all versions

Jordan Rupprecht b7ae7297b9 [llvm-ar] Implement the P modifier.
Summary:
GNU ar has a `P` modifier that changes filename comparisons to use full paths instead of the basename. As noted in the GNU docs, regular archives are not created with full path names, so P is used to deal with archives created by other archive programs (e.g. see the updated `absolute-paths.test` test case).

Since thin archives use full path names -- paths are relative to the archive -- it seems very error prone to not imply P when dealing with thin archives, so P is implied in those cases. (I think this is a deviation from GNU ar that makes sense).

This fixes PR37436 via https://github.com/ClangBuiltLinux/linux/issues/33.

As a note, this also undoes the `IsNew` parameter of handling relative paths in r288280. The unit test there still passes.

Essentially, all code in the project is now made available by the LLVM

include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of

Jordan Rupprecht 93bfb99ffc [llvm-ar] Flatten thin archives.
Summary:
Normal behavior for GNU ar is to flatten thin archives when adding them to another thin archive, i.e. add the members directly instead of nesting the archive.

Some refactoring done as part of this patch to ease things:
 - Consolidate `addMember`/`addLibMember` methods
 - Rename `addMember` to `addChildMember` to make it more visibly different at the call site that an archive child is passed instead of a regular member
 - Pass in a separate vector and splice it back into position instead of passing a vector + optional Pos (which makes expanding libs tricky)

This fixes PR37530 as raised by https://github.com/ClangBuiltLinux/linux/issues/279.
