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

[APFloat] Added a large unittest for APFloat.add that checks that special values are computed correctly.

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.

MIPS does not handle multiple relocations correctly, so two tests from the
unittests are expected to fail. These are:
 - MCJITTest.return_global and
 - MCJITTest.multiple_functions.

Until the multiple relocations are fixed, XFAIL the MCJIT unittests for
MIPS. This issue is tracked as Bug 16250.

Patch by Petar Jovanovic.

The old isNormal is already functionally replaced by the method isFiniteNonZero
in r184350 and all references to said method were replaced in LLVM/clang in
r184356/134366.

I forgot to to do this in r184356. The only references were in APFloatTest.cpp.

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

This is the first patch in a series of patches to rename isNormal =>
isFiniteNonZero and isIEEENormal => isNormal. In order to prevent careless
errors on my part the overall plan is:

1. Add the isFiniteNonZero predicate with tests. I can do this in a method
independent of isNormal. (This step is this patch).
2. Convert all references to isNormal with isFiniteNonZero. My plan is to
comment out isNormal locally and continually convert isNormal references =>
isFiniteNonZero until llvm/clang compiles.
3. Remove old isNormal and rename isIEEENormal to isNormal.
4. Look through all of said references from patch 2 and see if we can simplify
them by using the new isNormal.

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!

Specifically the following work was done:

1. If the operation was not implemented, I implemented it.

2. If the operation was already implemented, I just moved its location
in the APFloat header into the IEEE-754R 5.7.2 section. If the name was
incorrect, I put in a comment giving the true IEEE-754R name.

Also unittests have been added for all of the functions which did not
already have a unittest.

Added code to the unittest for APFloat::getSmallest to double check that we consider the result to be denormal.

I additionally changed certain checks to use EXPECT_FALSE instead of a boolean
complement with EXPECT_TRUE.

Alternative fix for problem addressed in r182233

Revision r182233 partially reverted the change in r181200 to simplify
JIT unif test #ifdefs, because that change caused a link error on some
host operating systems where the export list requires the following
symbols to be defined:

 JITTest_AvailableExternallyFunction
 JITTest_AvailableExternallyGlobal

As discussed on the list, the commit reverts r182233 (and re-installs
the full r181200 change), and instead fixes the link problem by moving
those two symbols to the top of the file and unconditionally defining
them.
