[ARM] Regenerate execute-only float comparison tests Prep work for PR40800 (Add UNDEF handling to SelectionDAG::FoldSetCC) llvm-svn: 357293

[ARM] Support float literals under XO When targeting execute-only and fp-armv8, float constants in a compare resulted in instruction selection failures. This is now fixed by using vmov.f32 where possible, otherwise the floating point constant is lowered into a integer constant that is moved into a floating point register. This patch also restores using fpcmp with immediate 0 under fp-armv8. Change-Id: Ie87229706f4ed879a0c0cf66631b6047ed6c6443 llvm-svn: 328313

[SelectionDAG] Add fcmp UNDEF handling to SelectionDAG::FoldSetCC Second half of PR40800, this patch adds DAG undef handling to fcmp instructions to match the behavior in llvm::ConstantFoldCompareInstruction, this permits constant folding of vector comparisons where some elements had been reduced to UNDEF (by SimplifyDemandedVectorElts etc.). This involves a lot of tweaking to reduced tests as bugpoint loves to reduce fcmp arguments to undef........ Differential Revision: https://reviews.llvm.org/D60006 llvm-svn: 357765

[SelectionDAG] Add fcmp UNDEF handling to SelectionDAG::FoldSetCC Second half of PR40800, this patch adds DAG undef handling to fcmp instructions to match the behavior in llvm::ConstantFoldCompareInstruction, this permits constant folding of vector comparisons where some elements had been reduced to UNDEF (by SimplifyDemandedVectorElts etc.). This involves a lot of tweaking to reduced tests as bugpoint loves to reduce fcmp arguments to undef........ Differential Revision: https://reviews.llvm.org/D60006 llvm-svn: 357765

[ARM] Support float literals under XO Follow up patch of r328313 to support the UseVMOVSR constraint. Removed some unneeded instructions from the test and removed some stray comments. Differential Revision: https://reviews.llvm.org/D44941 llvm-svn: 328691

[ARM] Support float literals under XO When targeting execute-only and fp-armv8, float constants in a compare resulted in instruction selection failures. This is now fixed by using vmov.f32 where possible, otherwise the floating point constant is lowered into a integer constant that is moved into a floating point register. This patch also restores using fpcmp with immediate 0 under fp-armv8. Change-Id: Ie87229706f4ed879a0c0cf66631b6047ed6c6443 llvm-svn: 328313
