Also, remove library dependencies for the sample analyzer-plugin. The only
library changes that would require a rebuild should be in headers, which
should already implicitly be marked as dependencies.

This is an optimistic version of create_diretories: it tries to create the
directory first and looks at the parent only if that fails.
Running strace on "mkdir -p" shows that it is pessimistic, calling mkdir on
every element of the path. We could implement that if needed.
In any case, with both strategies there is no reason to call stat, just check
the return of mkdir.

Summary:
This doesn't have any significant effect on the performance, but it
looks like a good thing to do.

Michael Sartain refactored RegisterContextPOSIX_* in r192332, and I must
have missed the now-shadowed variable when I rebased the FreeBSD MIPS64
register context after that.
llvm-svn: 201334
Summary:
AsmPrinter::EmitInlineAsm() will no longer use the EmitRawText() call for
targets with mature MC support. Such targets will always parse the inline
assembly (even when emitting assembly). Targets without mature MC support
continue to use EmitRawText() for assembly output.
The hasRawTextSupport() check in AsmPrinter::EmitInlineAsm() has been replaced
with MCAsmInfo::UseIntegratedAs which when true, causes the integrated assembler
to parse inline assembly (even when emitting assembly output). UseIntegratedAs
is set to true for targets that consider any failure to parse valid assembly
to be a bug. Target specific subclasses generally enable the integrated
assembler in their constructor. The default value can be overridden with
-no-integrated-as.
All tests that rely on inline assembly supporting invalid assembly (for example,
those that use mnemonics such as 'foo' or 'hello world') have been updated to
disable the integrated assembler.
Changes since review (and last commit attempt):
- Fixed test failures that were missed due to configuration of local build.
(fixes crash.ll and a couple others).
- Fixed tests that happened to pass because the local build was on X86
(should fix 2007-12-17-InvokeAsm.ll)
- mature-mc-support.ll's should no longer require all targets to be compiled.
(should fix ARM and PPC buildbots)
- Object output (-filetype=obj and similar) now forces the integrated assembler
to be enabled regardless of default setting or -no-integrated-as.
(should fix SystemZ buildbots)

This triggers on one of our internal tests.
Dmitri:
I do not understand this part of the codebase well enough to locate the
underlying cause easily. If the correct fix is not obvious, I can try to
debug the problem further or try to come up with reduced test case.

with Visual C++ 2013 by making libcxx definition text-identical to yvals.h.
Persumably this definition is for older Visual C++ versions.
In such cases it will still be defined so no functionality change.
Other platforms should not be affected as this is inside

With zero base shadow, shadow for near-zero access is itself at near-zero
location. As a result, this test crashes on the shadow access, and not on the
app access.
Relax a check to match this behavior.

It's not always true: on Android, strerror_r with invalid errno
prints "Unknown error ..." to the buffer and returns 0.
This test now only checks that strerror_r does not crash.

FIXME: CMAKE_*_SUFFIX may be set in HandleLLVMOptions if those variables could be writable, rather than to set one as target properties.

This changes ARM to use @llvm.fabs for floating-point vabs. Patterns
already existed in the backend, and it might help mid-end phases since
it's more likely to be understood than @llvm.arm.neon.vabs.

I'm not absolutely sure this is 100% correct solution, but it seems to

This commit is not strictly correct nor accounts for all uses (shared
objects, for example), but it allows one to test the compiler-rt library
on GNU targets.
Using this patch to run the test-suite has already shown me problems
on ARM. Since this is a Darwin-only flag, nobody is using it, so it
shouldn't be a problem.
I will need extension to deal with the shared cases, but since we're
not compiling libclang_rt.so, that's not yet applicable. Many other
problems will have to be fixed first in compiler-rt (such as removing
the 'arch' name from it and making it trully multi-arch, moving it to
the default lib directory, make both .a and .so variants, etc).
