![]() The functions may not clean up properly after using MMX registers. For the normal testing calls, the checkasm_checked_call functions will do the cleanup (and check that functions that should clean up do it as well), but when benchmarking functions that don't clean up, we don't currently properly clean up at all. This causes issues if a benchmarked function is followed by testing of a function that is supposed to not clobber the MMX/FPU state but doesn't touch it at all.
