[LLVMdev] Using llvm-mc assembler in the llvm test-suite

[Jim Grosbach]

Yes, absolutely. There's two pieces of this that are handy. First, checking the normal integrated-assembler code path. That doesn't check the actual assembler, but rather the binary encoder and object file emitter. To test that, I did runs with a locally modified clang that enabled the integrated assembler by default for my target (ARM/Darwin at the time). The second piece is checking the assembler itself. For that, I ran the full test suite and kept the .s files around. Then I ran each .s file through plain 'as' and llvm-mc and did a binary comparison of the results. Anything that showed up, I analyzed to see if it was innocuous or an error.
