2004-06-14Quick hack to get this file compiling again on Mac OS X. The right thing to doBrian Gaeke
is write an autoconf macro that checks whether __isnan or isnan actually works **using the C++ compiler after #include <cmath>**, instead of doing it the easy way with AC_CHECK_FUNCS(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14171 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
instructions, we can get rid of the FpUCOM/FpUCOMi pseudo instructions, which makes stuff simpler and faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14144 91177308-0d34-0410-b5e6-96231b3b80d8

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
