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

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.
This patch is a followup of https://reviews.llvm.org/D49915.

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.

There isn't any actual dependency - there's one #include from CodeGen

With this change we can use the MCA library from CodeGen without

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

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.

r342631 expanded bitc::METADATA_LOCATION by one element. The bitcode
metadata loader was changed in a backwards-incompatible way, leading to
crashes when disassembling old bitcode:
assertion: empty() && "PlaceholderQueue hasn't been flushed before being destroyed"
Assertion failed: (empty() && "PlaceholderQueue hasn't been flushed before being destroyed")
This commit teaches the metadata loader to assume that the newly-added
IsImplicitCode bit is 'false' when not present in old bitcode. I've added a
bitcode compat regression test.

x86 had 2 versions of peekThroughBitcast. DAGCombiner had 1. Plus, it had a 1-off implementation for the one-use variant.
Move the x86 versions of the code to SelectionDAG, so we don't have different copies of the code.
No functional change intended.
I'm putting this next to isBitwiseNot() because I am planning to use it in there. Another option is next to the
helpers in the ISD namespace (eg, ISD::isConstantSplatVector()). But if there's no good reason for those to be
there, I'd prefer to pull other helpers over to SelectionDAG in follow-up steps.
