MIPS floating-point comparisons are sometimes improved, sometimes pessimized. 
Here are the tests that are pessimized more:

gcc.c-torture/execute/ieee/compare-fp-1.c
gcc.c-torture/execute/ieee/compare-fp-4.c (-fno-trapping-math)
gcc.c-torture/unsorted/DFcmp.c

(not for all versions, but for example at -O1 -mfp32 -mgp32 they are affected).

Just removing these three is enough to change from a depressing
