Andrei Elovikov 7457aa0bce [LV] Don't call recordVectorLoopValueForInductionCast for newly-created IV from a trunc.
Summary:
This method is supposed to be called for IVs that have casts in their use-def
chains that are completely ignored after vectorization under PSE. However, for
truncates of such IVs the same InductionDescriptor is used during
creation/widening of both original IV based on PHINode and new IV based on
TruncInst.

This leads to unintended second call to recordVectorLoopValueForInductionCast
with a VectorLoopVal set to the newly created IV for a trunc and causes an
assert due to attempt to store new information for already existing entry in the
map. This is wrong and should not be done.

Fixes PR35773.

Craig Topper 7197a452fc [X86] Autoupgrade kunpck intrinsics using vector operations instead of scalar operations
Summary: This patch changes the kunpck intrinsic autoupgrade to use vXi1 shufflevector operations to perform vector extracts and concats. This more closely matches the definition of the kunpck instructions. Currently we rely on a DAG combine to turn the scalar shift/and/or code into a concat vectors operation. By doing it in the IR we get this for free.

Craig Topper f517f1a516 [X86] Implement old kunpck intrinsics using vector ops on vXi1 instead of integer shift/and/or
Summary:
kunpck intrinsics were removed in favor of native IR a few months ago. The implementation lowers them as by operation on the integer types passed to the intrinsic and then just shifting, masking, and oring them together. A special X86 DAG combine was added to recognize this patter and turn it into a concat_vector operation.

I think it makes more sense to keep the IR implementation closer to vector operations on vXi1. Given that we expect these builtins to be used around other builtins that operate on k-registers which we try to represent in IR with vXi1. InstCombine should be able to get rid of the bitcasts between integers and vXi1 leaving only the vector operations.

Craig Topper e9fc0cd920 [X86] Improve legalization of vXi16/vXi8 selects.
Extend vXi1 conditions of vXi8/vXi16 selects even before type legalization gets a chance to split wide vectors. Previously we would only extend 128 and 256 bit vectors. But if we start with a 512 bit vector or wider that needs to be split we wouldn't extend until after the split had taken place. By extending early we improve the results of type legalization.

Don't widen condition of 128/256 bit vXi16/vXi8 selects when we have BWI but not VLX. We can still use a mask register by widening the select to 512-bits instead. This is similar to what we do for compares already.

Brian Gesiak 4995614f7c [docs] Use monospace for PCH option flags
Summary:
Use monospace for option flags in the PCH section, instead of the

I believe these used to be links, for which single backticks would
have been appropriate, but since they were un-link-ified in
https://reviews.llvm.org/rL275560, I believe monospace is now more
appropriate, and so two backticks are needed.

Test Plan:
Build the `docs-clang-html` target and confirm the options are rendered
using monospace font.

Francis Ricci 0a80f8924b [Sanitizers, LSan, Darwin] Allow for lack of VM_MEMORY_OS_ALLOC_ONCE
Summary:
Some time ago, the sanitizers as of r315899 were imported into gcc mainline.  This broke
bootstrap on Darwin 10 and 11, as reported in GCC PR sanitizer/82824
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82824) due to the unconditional use
of VM_MEMORY_OS_ALLOC_ONCE.  This was only introduced in Darwin 13/Mac OS X 10.9.

The use of the macro was introduced in r300450.

I couldn't find any statement which Darwin versions are supposed to be supported by
LLVM, but the trivial patch to use the macro only if present allowed the gcc bootstrap
to finish.

So far, I haven't tried building llvm/compiler-rt  on Darwin 11.  Maybe the patch is
simple enough to go in nonetheless.

Aaron Smith 10a02577ea [lldb] Add support to cache a PDB's global scope and fix a bug in getting the source file name for a compiland
Summary:
This commit is a combination of the following changes:
    
- Cache PDB's global scope (executable) in SymbolFilePDB  

- Change naming of `cu` to `compiland` which is PDB specific   

- Change ParseCompileUnitForSymIndex to ParseCompileUnitForUID.
   Prefer using a common name `UID` instead of PDB's `System Index`
   Adding one more argument `index` to this method, which is used to
   specify the index of the compile unit in a cached compile unit array
    
- Add GetPDBCompilandByUID method to simply code
    
- Fix a bug in getting the source file name for a PDB compiland.
   For some reason, PDBSymbolCompiland::getSourceFileName() could
   return an empty name, so if that is true, we have to walk through all
   source files of this compiland and determine the right source file
   used to generate this compiland based on language indicated.
    
   The previous implementation called PDBSession::findOneSourceFile 
   method to get its name for the compiland. This is not accurate since
   the `one source file` found could be a header other than source file.
