The LLVM tools can be used as a replacement for binutils, in which case
it's convenient to create symlinks with the binutils names. Add support
for these symlinks in the build system. As with any other llvm tool
symlinks, the user can limit the installed symlinks by only adding the
desired ones to `LLVM_TOOLCHAIN_TOOLS`.

writeArchive returned a pair, but the first element of the pair is always
its first argument on failure, so it doesn't make sense to return it from
the function. This patch change the return type so that it does't return it.

Summary:
Use the filepath used to open the archive member as the archive member
name instead of the file basename. This path might be absolute or
relative. This is important because the archive member name will show
up in the PDB, and we want our PDBs to look as much like MSVC's as
possible.
This also helps avoid an issue in our PDB module descriptor writing
code, which assumes that all module names are unique. Relative paths
still aren't guaranteed to be unique, but they're much better than
basenames, which definitely aren't unique.

For whatever reason ld64 requires that member headers (not the member
themselves) should be aligned. The only way to do that is to edit the
previous member so that it ends at an aligned boundary.
Since modifying data put in an archive is an undesirable property,
llvm-ar should only do it when it is absolutely necessary.

llvm/IR/Attributes.gen

Summary:
Most of the changes are very straight-forward. The only choice I had to make was
to use second-precision time points in the Archive classes. I did this because
the archive files use that precision in the on-disk representation anyway.

Summary:
This is a follow-up to D25416. It removes all usages of TimeValue from
llvm/Support library (except for the actual TimeValue declaration), and replaces
them with appropriate usages of std::chrono. To facilitate this, I have added
small utility functions for converting time points and durations into appropriate
OS-specific types (FILETIME, struct timespec, ...).

As mentioned in commit log for r276686 this next step is adding a new
method in the ArchiveMemberHeader class to get the full name that
does proper error checking, and can be use for error messages.
To do this the name of ArchiveMemberHeader::getName() is changed to
ArchiveMemberHeader::getRawName() to be consistent with
Archive::Child::getRawName(). Then the “new” method is the addition
of a new implementation of ArchiveMemberHeader::getName() which gets
the full name and provides proper error checking. Which is mostly a rewrite
of what was Archive::Child::getName() and cleaning up incorrect uses of
llvm_unreachable() in the code which were actually just cases of errors
in the input Archives.
Then Archive::Child::getName() is changed to return Expected<> and use
the new implementation of ArchiveMemberHeader::getName() .
Also needed to change Archive::getMemoryBufferRef() with these
changes to return Expected<> as well to propagate Errors up.
As well as changing Archive::isThinMember() to return Expected<> .

See http://reviews.llvm.org/D22079
Changes the Archive::child_begin and Archive::children to require a reference
to an Error. If iterator increment fails (because the archive header is
damaged) the iterator will be set to 'end()', and the error stored in the
given Error&. The Error value should be checked by the user immediately after
the loop. E.g.:
Error Err;
for (auto &C : A->children(Err)) {
// Do something with archive child C.
}
// Check the error immediately after the loop.
if (Err)
return Err;
Failure to check the Error will result in an abort() when the Error goes out of
scope (as guaranteed by the Error class).

The NewArchiveIterator class has a problem: it requires too much context. Any
memory buffers added to the archive must be stored within an Archive::Member,
which must have an associated Archive. This makes it harder than necessary
to create new archive members (or new archives entirely) from scratch using
memory buffers.
This patch replaces NewArchiveIterator with a NewArchiveMember class that
stores just the memory buffer and the information that goes into the archive
member header.

binutils ar uses -plugin to specify the LTO plugin, but LLVM doesn't

Try to be more clever about selecting the default format. When an existing
archive is used, use the type of the archive to determine the format. When
existing members are present, use the first member's format to determine the
format to use. If we are creating an empty archive (MRI mode) or are adding
non-object members, default to the current behaviour of using the host type due
to the lack of a better alternative. This aids in cross-compilation on Darwin
to non-Darwin platforms which rely on GNU format archives.

updated.
When updating an existing archive, llvm-ar opens the old archive into a
`MemoryBuffer`, does its thing, and writes the results to a temporary
file. That file is then renamed to the original archive filename, thus
replacing it with the updated contents. However, on Windows at least,
what would happen is that the `MemoryBuffer` for the old archive would
actually be an mmap'ed view of the file, so when it came time to do the
rename via Win32's `ReplaceFile`, it would succeed but would be unable
to fully replace the file since there would still be a handle open on
it; instead, the old version got renamed to a random temporary name and
left behind.
