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

[SDAG] Don't widen VSETCC during type legalization for split operands Because the operands of a vector SETCC node can be of a different type from the result (and often are), it can happen that even if we'd prefer to widen the result type of the SETCC, the operands have been split instead. In this case, the SETCC result also must be split. This mirrors what is done in WidenVecRes_SELECT, and should be NFC elsewhere because if the operands are not widened the following calls to GetWidenedVector will assert (which is what was happening in the test case). llvm-svn: 232935

[PPC] Enable transformations in PPCPassConfig::addIRPasses at O2 http://reviews.llvm.org/D18562 A large number of testcases has been modified so they pass after this test. One testcase is deleted, because I realized even after undoing the original change that was committed with this testcase, the testcase still passes. So I removed it. The change to one other testcase (test/CodeGen/PowerPC/pr25802.ll) is an arbitrary change to keep it passing. Given the original intention of the testcase, and the fact that fixing it will require some time to change the testcase, we concluded that this quick change will be enough. llvm-svn: 265683
