Adding -verify-machineinstrs option to PowerPC tests Currently we have a number of tests that fail with -verify-machineinstrs. To detect this cases earlier we add the option to the testcases with the exception of tests that will currently fail with this option. PR 27456 keeps track of this failures. No code review, as discussed with Hal Finkel. llvm-svn: 277624

Add PPC option for full register names in asm On non-Darwin PPC systems, we currently strip off the register name prefix prior to instruction printing. So instead of something like this: mr r3, r4 we print this: mr 3, 4 The first form is the default on Darwin, and is understood by binutils, but not yet understood by our integrated assembler. Once our integrated-as understands full register names as well, this temporary option will be replaced by tying this functionality to the verbose-asm option. The numeric-only form is compatible with legacy assemblers and tools, and is also gcc's default on most PPC systems. On the other hand, it is harder to read, and there are some analysis tools that expect full register names. llvm-svn: 194384
