2004-06-11Add two options to the program:Reid Spencer
-release causes ENABLE_OPTIMIZED=1 to be added to the make line so that the test runs against optimized code. -pedantic causes the CompileOptimizeOpts variable to be overridden to add several additional warnings not picked up by -Wall. This should help catch additional programming faux pas. See the diff for the specific details. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14153 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-11By far, one of the most common uses of isnan is to make 'isunordered'Chris Lattner
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.

2004-06-11Now that compare instructions aren't lumped in with the other twoargfp ↵Chris Lattner

2004-06-11Split compare instruction handling OUT of handleTwoArgFP into handleCompareFP.Chris Lattner
This makes the code much simpler, and the two cases really do belong apart. Once we do it, it's pretty obvious how flawed the logic was for A != A case, so I fixed it (fixing PR369). This also uses freeStackSlotAfter instead of inserting an fxchg then popStackAfter'ing in the case where there is a dead result (unlikely, but possible), producing better code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14139 91177308-0d34-0410-b5e6-96231b3b80d8
