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 the PPC fcpsgn instruction Modern PPC cores support a floating-point copysign instruction, and we can use this to lower the FCOPYSIGN node (which is created from calls to the libm copysign function). A couple of extra patterns are necessary because the operand types of FCOPYSIGN need not agree. llvm-svn: 188653

[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
