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 ExpandFloatOp_FCOPYSIGN to handle ppcf128-related expansions We had previously been asserting when faced with a FCOPYSIGN f64, ppcf128 node because there was no way to expand the FCOPYSIGN node. Because ppcf128 is the sum of two doubles, and the first double must have the larger magnitude, we can take the sign from the first double. As a result, in addition to fixing the crash, this is also an optimization. llvm-svn: 188655

[PPC] Adjust some PowerPC tests to account for presence/absence of VSX Patch by Bill Seurer; committed on his behalf. These test cases generate slightly different code sequences when VSX is activated and thus fail. The update turns off VSX explicitly for the existing checks and then adds a second set of checks for most of them that test the VSX instruction output. llvm-svn: 220019
