Vikram S. Adve 0b32273208 Significant changes to correctly spill CC registers and to correctly ... handle conditional move instructions: -- cpMem<->Reg functions now support CC registers (int and FP) correctly. -- Scratch registers must be explicitly provided to cpMem<->Reg when needed, since CC regs need one to be copied to/from memory. -- CC regs are saved to a scratch register instead of stack. -- All regs used by a instruction are now recorded in MachineInstr::regsUsed, since regs used to save values *across* an instruction are not obvious either from the operands or from the LiveVar sets. -- An (explicit or implicit) operand may now be both a def and a use. This is needed for conditional move operations. So an operand may need spill code both before and after the instruction. -- class MachineCodeForBasicBlock is now an annotation on BasicBlock. llvm-svn: 2833		2002-07-08 23:15:32 +00:00
