Adding TBM feature to bdver2 processor; piledriver supports this instruction set

We were previously mostly passing it through, but -O0 and -O3 are not valid
options to cl.exe.

We should translate -O0 to /Od and -O3 to /Ox. -O{1,2,s} get passed through.

llvm-svn: 191323

Options that leak from other parts of LLVM are now pruned out of -help.

-version output is specific to clang-apply-replacements now.

This code isn't ready to deal with allocation functions where the return is not
the allocated pointer. The checks below will reject posix_memalign anyways.

We really don't want to optimize malloc return value checks away.

class/protocol decls in @implementation and
fixup modern rewriter to handle that.

This is safe per C++11 18.6.1.1p3: [operator new returns] a non-null pointer to
suitably aligned storage (3.7.4), or else throw a bad_alloc exception. This
requirement is binding on a replacement version of this function.

Brings us a tiny bit closer to eliminating more vector push_backs.

Use getNumOccurrences instead of usina a default constant string.

to build out the symbol table as addresses are used, and implements
the mechanism for ELF to add stripped symbols from eh_frame.

Uses this mechanism to allow disassembly for addresses corresponding
to stripped symbols for ELF, and provide hooks to implement this for
PE COFF.

Also removes eSymbolContextTailCall in favor of an option for
ResolveSymbolContextForAddress for consistency with the documentation
for eSymbolContextEverything.  Essentially, this is just an option for
interpreting the so_addr.

[mips][msa] Added support for matching ilv[lr], ilvod, and ilvev from normal IR (i.e. not intrinsics)

Most constant BUILD_VECTOR's are matched using ComplexPatterns which cover
bitcasted as well as normal vectors. However, it doesn't seem to be possible to
match ldi.[bhwd] in a type-agnostic manner (e.g. to support the widest range of
immediates, it should be possible to use ldi.b to load v2i64) using TableGen so
ldi.[bhwd] is matched using custom code in MipsSEISelDAGToDAG.cpp

This made the majority of the constant splat BUILD_VECTOR lowering redundant.
The only transformation remaining for constant splats is when an (up-to) 32-bit
constant splat is possible but the value does not fit into a 10-bit signed
integer. In this case, the BUILD_VECTOR is transformed into a bitcasted
BUILD_VECTOR so that fill.[bhw] can be used to splat the vector from a GPR32
register (which is initialized using the usual lui/addui sequence).

There are no additional tests since this is a re-implementation of previous
functionality. The change is intended to make it easier to implement some of
the upcoming instruction selection patches since they can rely on existing
support for BUILD_VECTOR's in the DAGCombiner.

compare_float.ll changed slightly because a BITCAST is no longer
introduced during legalization.

This patch turns the -mv* hexagon options into aliases. We should really produce
errors for invalid versions in the driver, but this patch preserves the old
behavior for now.

[mips][msa] Non-constant BUILD_VECTOR's should be expanded to INSERT_VECTOR_ELT instead of memory operations.

The resulting code is the same length, but doesnt cause memory traffic or latency.

llvm-svn: 191297

This covers the case where fmax_a can be used to implement ISD::FABS.

llvm-svn: 191296

No functional change.

Since the error is always reported by one of the GCD workers, this will help avoid premature program termination with exit code 0.
