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

[PowerPC] Fix the int2fp(fp2int(x)) DAGCombine to ignore ppc_fp128 This DAGCombine was creating custom SDAG nodes with an illegal ppc_fp128 operand type because it was triggering on f64/f32 int2fp(fp2int(ppc_fp128 x)), but shouldn't (it should only apply to f32/f64 types). The result was a crash. llvm-svn: 245530

[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
