gcc started generating this rubbish around version 3.4, if I recall correctly. I've tried disabling various optimisations, but can't seem to convince gcc not to generate the extra jump. You don't get this from the native code generator, BTW.
But the comparison is present in the C code. What do you want GCC to do?
in addition to the expected conditional jump, it is adding another unconditional jump and an indirect jump to a constant. John -- John Meacham - ⑆repetae.net⑆john⑈
