; Test that compares are omitted if CC already has the right value
[SystemZ] Reuse CC results for integer comparisons with zero This also fixes a bug in the predication of LR to LOCR: I'd forgotten that with these in-place instruction builds, the implicit operands need to be added manually. I think this was latent until now, but is tested by int-cmp-45.c. It also adds a CC valid mask to STOC, again tested by int-cmp-45.c. llvm-svn: 187573

Use the integrated assembler as default on SystemZ This was already done in clang, this commit now uses the integrated assembler as default when using LLVM tools directly. A number of test cases deliberately using an invalid instruction in inline asm now have to use -no-integrated-as. llvm-svn: 225820
