Eric Fiselier 599a842522 Add private option to change build dialect from C++11
Although libc++ only requires C++11 to build, there are other
reasons to turn on a newer dialect in the build. For example
IDE's may not highlight any C++14/C++17 in the headers when
configured for C++11. This patch add's a private option for
changing this.

Igor Breger 8672408db0 [AVX512] Fix insertelement i1 lowering.
1. Use shuffle to insert element i1 into vector. The previous implementation was incorrect ( dest_bit OR src_bit , it doesn't clear the bit if src_bit=0 )
2. Improve shuffle i1 vector, use CVT2MASK if supported instead TRUNCATE.

Sanjoy Das 2143447c73 [IRCE] Create llvm::Loop instances for cloned out loops
llvm-svn: 278618
2016-08-14 01:04:46 +00:00
Sanjoy Das 7a18a238c6 [IRCE] Don't iterate on loops that were cloned out
IRCE has the ability to further version pre-loops and post-loops that it
created, but this isn't useful at all.  This change teaches IRCE to
leave behind some metadata in the loops it creates (by cloning the main
loop) so that these new loops are not re-processed by IRCE.

Today this bug is hidden by another bug -- IRCE does not update LoopInfo
properly so the loop pass manager does not re-invoke IRCE on the loops
it split out.  However, once the latter is fixed the bug addressed in
this change causes IRCE to infinite-loop in some cases (e.g. it splits
out a pre-loop, a pre-pre-loop from that, a pre-pre-pre-loop from that
and so on).

Mehdi Amini a71002e7f1 Fix bitcode auto-upgrade when using bitcode lazy loading
The auto-upgrade path could be called before the VST (global
names) was fully parsed, and thus intrinsic names were not
available and the autoupgrade logic could not operate.

Fix link failures with ThinLTO.

This is a recommit of r278610 with a different fix.

Ron Lieberman 822ee88ab8 Fix unsupported relocation type R_HEX_6_X' for symbol .rodata
LowerTargetConstantPool is not properly setting the TargetFlag to indicate
desired relocation. Coding error, the offset parameter was omitted, so the
TargetFlag was used as the offset, and the TargetFlag defaulted to zero.

This only affects -fpic compilation, and only those items created in a
Constant Pool, for example a vector of constants. Halide ran into this issue.

Sanjoy Das 1b1272f515 [IRCE] Fix test case; NFC
The (negative) test case is supposed to check that IRCE does not muck
with range checks it cannot handle, not that it does the right thing in
the absence of profiling information.

Craig Topper 8c372a31b7 [X86] Add a check of isCommutable at the top of X86InstrInfo::findCommutedOpIndices. Most callers don't check if the instruction is commutable before calling.
