- Add target lowering hooks that specify which setcc conditions are illegal, i.e. conditions that cannot be checked with a single instruction. For example, SETONE and SETUEQ on x86. - Teach legalizer to implement illegal setcc as a and / or of a number of legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is implemented as SETO & SETNE, SETUEQ is SETUO \| SETEQ. - Move x86 target over. llvm-svn: 57542 2008-10-15 04:05:31 +02:00
