I will remove the V1 version as soon as I change clang in the next commit.

Revert "BlockFrequency: Saturate at 1 instead of 0 when multiplying a frequency with a branch probability."

This reverts commit r184584. Breaks PPC selfhost.

llvm-svn: 184590

Zero is used by BlockFrequencyInfo as a special "don't know" value. It also
causes a sink for frequencies as you can't ever get off a zero frequency with
more multiplies.

This recovers a 10% regression on MultiSource/Benchmarks/7zip. A zero frequency
was propagated into an inner loop causing excessive spilling.

PR16402.

Modified the implementation of fs::GetUniqueID on Windows such that it actually finds a unique identifier for a file.  Also adds unit tests for GetUniqueID.

llvm-svn: 184351

llvm-svn: 183940

It was only used to implement ExecuteAndWait and ExecuteNoWait. Expose just
those two functions and make Execute and Wait implementations details.

Most clients have already been moved from Path V1 to V2. The ones using V1
now include PathV1.h explicitly.

sys::process::get_id() now returns the process ID instead of a process handle on Windows.  Patch thanks to Kim Gräsman!

Add a stringize method to make dumping a bit easier, and add a testcase
exercising a few different paths.

Implemented public interface for modifying registered (not positional or sink options) command line options at runtime.

This seemed like the cleanest way to find the test executable.  Also fix
the file mode.

llvm-svn: 180770

That seems to interact poorly with the environ and _environ macros
defined in MSVC's <stdlib.h>.

Also remove the incorrect comment about _NSGetEnviron().

This was r180041 and r180046, which was reverted in r180066.
Re-committing this should fix the dragonegg bootstrap, which I presume
needs LD_LIBRARY_PATH to be propagated to the child.

Tested on Linux, Windows, and Mac OS 10.6.

Add basic zlib support to LLVM. This would allow to use compression/uncompression in selected LLVM tools.

Revert "[Support] Propagate the environment into the test child process"

This reverts commit r180046.
This reverts commit r180041.

These have broken buildbots for ~3 hours:

llvm-svn: 180066

Pointed out by Eli.  The test passes for me either way, so I missed
this.

llvm-svn: 180046

Should fix the dragonegg bootstrap builder, which reasonably needs
LD_LIBRARY_PATH to be set.

Summary:
This is http://llvm.org/PR15802.  Backslashes preceding double quotes in
arguments must be escaped.  The interesting bit is that all other
backslashes should *not* be escaped, because the un-escaping logic is
only triggered by the presence of a double quote character.

This reverts commit a33e1fafac7fedb1b080ef07ddf9ad6ddff3a830.

This unit test crashes on Darwon. It needs to be temporarily reverted
to unblock the test infrastructure.

ErrorOr<void> represents an operation that returns nothing, but can still fail.
It should be used in cases where you need the aditional user data that ErrorOr
provides over error_code.
