http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45585 --- Comment #7 from Dominique d'Humieres dominiq at lps dot ens.fr 2010-11-07 11:45:18 UTC --- I have posted at http://gcc.gnu.org/ml/gcc-testresults/2010-11/msg00551.html the result of the regtest with the patch in comment #5. The patch fixes this PR without adding regressions of its own (the new failures are also seen in http://gcc.gnu.org/ml/gcc-testresults/2010-11/msg00540.html and gfortran.dg/vect/pr45714-b.f failed before the patch). Thanks.

What is happening is originally if you were loading up a static 64-bit integer variable to convert it to floating point, the compiler would first load the variable into a GPR, then store it on the stack, and then load the value from the stack to the FPR. My optimization allowed the fp convert to take memory operands so it didn't have to go through the GPR registers. However, since Darwin has its own patterns for load/store, it didn't go through the normal move patterns, and was overlooked.
