[CMake] add_lit_target: Let lit.site.cfg free from "--param build_mode" on single configuration builds, like autoconf build.

And add the proper fix.

This currently breaks clang/test/CodeGen/code-coverage.c. The root cause
is that the newly introduced access to Funcs[j] is out of bounds.

The function checksums are hashed from the concatenation of the function
name and line number.

llvm-svn: 196358

Added additional checks for the Identifier, CfgChecksum and Name for
each GCOVFunction. Also added function names in error messages.

This splits the file-scope read() function into readGCNO() and
readGCDA(). Also broke file format read into functions that first read
the file type, then check the version.

Thanks for j`ey and Sean Silva for noticing it.

It appears to be referring to nonexistent entities. This must be a
carry-over from an older version of the document.

this completes the basic port of ARM constant islands to Mips16.
More testing, code review, cleanup is in order but basically everything
seems to be working. A bug in gas is preventing some of the runtime
testing but I hope to resolve this soon.

Add --assertion-mode to llvm-config. It emits ON or OFF according to NDEBUG.

utils/llvm-lit: Generate "llvm-lit.py" rather than "llvm-lit" on Win32 hosts to let llvm-lit.py --use-processes work.

llvm-lit needs suffix.py for multiprocess to find a main module.

Unlike msvc, when handling a thiscall + sret gcc will
* Put the sret in %ecx
* Put the this pointer is (%esp)

This fixes, for example, calling stringstream::str.

This fixes a logic bug pointed out by Juraj Ivancic.

No behavior change because none of the in-tree clients of
cl::ExpandResponseFiles check the return value.  In this case, the
@prefixed arguments are left in the command line.  Downstream command
line processing has the opportunity to emit errors about it, so this
isn't that bad.

Copy all test files to temporary directory, not just test.* files. Tests
didn't fail because the missing files occurred in XFAILS.

clang enables vectorization at optimization levels > 1 and size level < 2. opt
should behave similarily.

Loop vectorization and SLP vectorization can be disabled with the flags
-disable-(loop/slp)-vectorization.

Testcase added.

llvm-svn: 196269

The backend converts 64-bit ORs into subreg moves if the upper 32 bits
of one operand and the low 32 bits of the other are known to be zero.
It then tries to peel away redundant ANDs from the upper 32 bits.

Since AND masks are canonicalized to exclude known-zero bits,
the test ORs the mask and the known-zero bits together before
checking for redundancy.  The problem was that it was using the
wrong node when checking for known-zero bits, so could drop ANDs
that were still needed.

- The fix to PR17631 fixes part of the cases where 'vzeroupper' should
  not be issued before 'call' insn. There're other cases where helper
  calls will be inserted not limited to epilog. These helper calls do
  not follow the standard calling convention and won't clobber any YMM
  registers. (So far, all call conventions will clobber any or part of
  YMM registers.)
  This patch enhances the previous fix to cover more cases 'vzerosupper' should
  not be inserted by checking if that function call won't clobber any YMM
  registers and skipping it if so.

The communication protocol is unstable on ARM when compiled
with Clang, which is disrupting the self-hosting buildbots that
are going to be added this week. I'm working on a solution, but
remote MCJIT is not high-priority for ARM at the moment, so it
might take a while.

It turns out that in some build systems, tests are executed in a
non-writable directory. Hopefully, this finally fixes the issue.
