[PowerPC 4/4] Enable little-endian support for VSX. With the foregoing three patches, VSX instructions can be used for little endian. This patch removes the restriction that prevented this, and re-enables the test cases from the first three patches. llvm-svn: 223792

[PowerPC] v4i32 is a VSRCRegClass I was looking at some vector code generation and kept seeing unnecessary vector copies into the Altivec half of the VSX registers. I discovered that we overlooked v4i32 when adding the register classes for VSX; we only added v4f32 and v2f64. This means that anything that canonicalizes into v4i32 (which is a LOT of stuff) ends up being forced into VRRC on its way to VSRC. The fix is one line. The rest of the patch is fixing up some test cases whose code generation has changed as a result. This seems like it would be a good candidate for backport to 3.7. llvm-svn: 242442

[PowerPC] Enable printing instructions using aliases TableGen had been nicely generating code to print a number of instructions using shorter aliases (and PowerPC has plenty of short mnemonics), but we were not calling it. For some of the aliases we support in the parser, TableGen can't infer the "inverse" alias relationship, so there is still more to do. Thus, after some hours of updating test cases... llvm-svn: 235616

[PowerPC] Add an MI SSA peephole pass. This patch adds a pass for doing PowerPC peephole optimizations at the MI level while the code is still in SSA form. This allows for easy modifications to the instructions while depending on a subsequent pass of DCE. Both passes are very fast due to the characteristics of SSA. At this time, the only peepholes added are for cleaning up various redundancies involving the XXPERMDI instruction. However, I would expect this will be a useful place to add more peepholes for inefficiencies generated during instruction selection. The pass is placed after VSX swap optimization, as it is best to let that pass remove unnecessary swaps before performing any remaining clean-ups. The utility of these clean-ups are demonstrated by changes to four existing test cases, all of which now have tighter expected code generation. I've also added Eric Schweiz's bugpoint-reduced test from PR25157, for which we now generate tight code. One other test started failing for me, and I've fixed it (test/Transforms/PlaceSafepoints/finite-loops.ll) as well; this is not related to my changes, and I'm not sure why it works before and not after. The problem is that the CHECK-NOT: of "statepoint" from test1 fails because of the "statepoint" in test2, and so forth. Adding a CHECK-LABEL in between keeps the different occurrences of that string properly scoped. llvm-svn: 252651
