Add -mcpu to some unit tests that only fail on certain hosts. llvm-svn: 184709

Compile x86-64-and-mask.ll into: _test: movl %edi, %eax ret instead of: _test: movl $4294967295, %ecx movq %rdi, %rax andq %rcx, %rax ret It would be great to write this as a Pat pattern that used subregs instead of a 'pseudo' instruction, but I don't know how to do that in td files. llvm-svn: 47658

Use a 32-bit and with implicit zero-extension instead of a 64-bit and if it has an immediate with at least 32 bits of leading zeros, to avoid needing to materialize that immediate in a register first. FileCheckize, tidy, and extend a testcase to cover this case. This fixes rdar://7527390. llvm-svn: 93160

; This should be a single mov, not a load of immediate + andq.
Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion. This was done with the following sed invocation to catch label lines demarking function boundaries: sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct. llvm-svn: 186258
