Evan Cheng	3b0f5e4d61	- 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 02:05:31 +00:00

- 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.
