Hi,I'm still developping a new private target backend (gcc4.5.2) and I noticed something strange in the assembler generated for conditionnal jump.
Maybe unfortunate defnition of branch costs or rtx costs?
How can I tell GCC to perform the best conditionnal jump by sometimes reversing the comparison ?
You can expand to a form that's best. Moreover there is CANONICALIZE_COMPARISON hook.
