several things that were neither in an anonymous namespace nor static
but not intended to be global.

Teach X86 a few more vsetcc patterns.  Custom lowering for unsupported ones is next.

llvm-svn: 51009

Xform bitconvert(build_pair(load a, load b)) to a single load if the load locations are at the right offset from each other.

if those blocks consist entirely of common instructions;
merging will not add an extra branch in this case.

changes that don't change functionality.

"is{Trivially,Really}ReMaterializable" methods.

semantically identical, but little difference in
either results or execution speed; but it's much
easier to read, at least IMO.

Hard code CmpInst back to i1 for now while I go track down what in the bitcode reader/writer is assuming i1
This was breaking a bunch of tests

This is necessary to unbreak the build.

possible for it to produce worse code than before.

The rest of this patch is code cleanup.

Makes it possible to use options with names like "Wa,".
Also fixes the -Wall option handling as a side-effect.

Move the various analyses used by GVN into static variables so we don't have to keep passing them around or refetching them.

llvm-svn: 50963

SCCP like sparse lattice analysis with relative ease.  Just pick your
lattice function and implement the transfer function and you're good.
Just make sure you don't break monotonicity ;-)

llvm-svn: 50961

include backslashes on Windows. This should fix llvm-ld problems on win32.
