- replaced with getcwd/_getcwd as appropriate for current platform

Revising the MCJIT ObjectCache interface to allow subclasses to avoid retaining references to returned objects

llvm-svn: 185221

- lit tests verify that each line of input LLVM IR gets a !dbg node and a
  corresponding entry of metadata that contains the line number 
- unit tests verify that DebugIR works as advertised in the interface
- refactored some useful IR generation functionality from the MCJIT unit tests
  so it can be reused

Allow a BlockFrequency to be divided by a non-zero BranchProbability
with saturating arithmetic. This will be used to compute the frequency
of a loop header given the probability of leaving the loop.

Our long division algorithm already saturates on overflow, so that was a
freebie.

There are a few valid situation where we care about the structure inside a
directory, but not about the directory itself. A simple example is for unit
testing directory traversal.

PathV1 had a function like this, add one to V2 and port existing users of the
created temp file and delete it hack to using it.

[APFloat] Added unittest for APFloat.divide that checks special cases, result categories, and result statuses.

[APFloat] Added unittest for APFloat.multiply that checks special cases, result categories, and result status.

[APFloat] Added unittest for APFloat.subtract that checks special cases, result categories, and result status.

llvm itself is now PathV1 clean.

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.

llvm-svn: 184431

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.

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.

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.
