Chris Lattner 1435b94f62 Fold FP comparisons where one operand is converted from an integer ... type and the other operand is a constant into integer comparisons. This happens surprisingly frequently (e.g. 10 times in 471.omnetpp), which are things like this: %tmp8283 = sitofp i32 %tmp82 to double %tmp1013 = fcmp ult double %tmp8283, 0.0 Clearly comparing tmp82 against i32 0 is cheaper here. this also triggers 8 times in gobmk, including this one: %tmp375376 = sitofp i32 %tmp375 to double %tmp377 = fcmp ogt double %tmp375376, 8.150000e+01 which is comparing an integer against 81.5 :). llvm-svn: 51268		2008-05-19 20:18:56 +00:00
