r342698 removed the 'UNSUPPORTED: windows' flags from a number of fuzzer
tests, however too many lines were removed from 'fuzzer-flags.test',
including the run-line that generates the test binary, which breaks that
test for me (and the clang-x64-ninja-win7 buildbot). This patch just
re-adds that line.

    Summary: This change is the first part of the AMDGPU target description
    change. The aim of it is the effective splitting the vector and scalar
    flows at the selection stage. Selection uses predicate functions based
    on the framework implemented earlier - https://reviews.llvm.org/D35267

Summary:
The goal of D49916 is to remove some hit counters from lines like '}'.
So as a consequence, the tests must be fixed.
FYI, after holidays, I'll add more tests.

Summary:
Some lines have a hit counter where they should not have one.
Cleanup stuff is located to the last line of the body which is most of the time a '}'.
And Exception stuff is added at the beginning of a function and at the end (represented by '{' and '}').
So in such cases, the DebugLoc used in GCOVProfiling.cpp must be marked as not covered.

Of course some bots don't have std::is_trivially_constructible...

llvm-svn: 342711

Summary: As discussed in r341853 by blaikie, the reinterpret_cast was technically an aliasing violation. Restrict our bit_cast implementation to To which are trivially-constructible (and note the existing restriction to constexpr). Once we move to C++17 we can use a version of bit_cast without these restrictions, or if we care we can SFINAE a different implementation when To isn't trivially-constructible.

There is a memory leak which is detected in some of the sanitizer builds.
MCSymbolWasm contains SmallVectors for holding signature information,
however MCContext doesn't run destructors for MCSymbols, so in cases
where the SmallVectors heap-allocate, the memory is leaked.

llvm-svn: 342707

Summary:
There isn't any actual dependency - there's one #include from CodeGen
but nothing from the header is actually used.

With this change we can use the MCA library from CodeGen without
circular dependencies (e.g. for scheduling).

This is a bit easier to follow than handling the copy and src maps
directly in the pass, and will make upcoming changes to how this is
done easier to follow.

Summary:
Implement --version for objcopy and strip.

I think there are LLVM utilities that automatically handle this, but that doesn't seem to work with custom parsing since this binary handles both objcopy and strip, so it uses custom parsing.

The 'test_filename' property in TestBase changes over time, so
attempting to find a check file relative to the directory containing
'test_filename' is flaky.

Use the absolute path of the check file as that's always correct (and
simpler). This relies on the test driver changing into the test
directory, which it seems we can safely assume.

As a drive-by, make self.filecheck respect the trace (-t) option.

Removing on behalf of Jorge Moya.  This test is broken on
Windows due to it actually being able to resolve the path.  There
is an actual Windows-specific bug somewhere, but we already have
sufficient test coverage of this with a different test, so removing
this was the approach suggested by Jorge.

Currently, BPF has XADD (locked add) insn support and the
asm looks like:
  lock *(u32 *)(r1 + 0) += r2
  lock *(u64 *)(r1 + 0) += r2
The instruction itself does not have a return value.

At the source code level, users often use
  __sync_fetch_and_add()
which eventually translates to XADD. The return value of
__sync_fetch_and_add() is supposed to be the old value
in the xadd memory location. Since BPF::XADD insn does not
support such a return value, this patch added a PreEmit
phase to check such a usage. If such an illegal usage
pattern is detected, a fatal error will be reported like
  line 4: Invalid usage of the XADD return value
if compiled with -g, or
  Invalid usage of the XADD return value
if compiled without -g.
