comparisons. In an 'isunordered' predicate, which looks like this at the LLVM level: %a = call bool %llvm.isnan(double %X) %b = call bool %llvm.isnan(double %Y) %COM = or bool %a, %b We used to generate this code: fxch %ST(1) fucomip %ST(0), %ST(0) setp %AL fucomip %ST(0), %ST(0) setp %AH or %AL, %AH With this patch, we generate this code: fucomip %ST(0), %ST(1) fstp %ST(0) setp %AL Which should make alkis happy. Tested as X86/compare_folding.llx:test1 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14148 91177308-0d34-0410-b5e6-96231b3b80d8 |
