Jakob Stoklund Olesen a8ad97743d Slightly change the meaning of the reMaterialize target hook when the original ... instruction defines subregisters. Any existing subreg indices on the original instruction are preserved or composed with the new subreg index. Also substitute multiple operands mentioning the original register by using the new MachineInstr::substituteRegister() function. This is necessary because there will soon be <imp-def> operands added to non read-modify-write partial definitions. This instruction: %reg1234:foo = FLAP %reg1234<imp-def> will reMaterialize(%reg3333, bar) like this: %reg3333:bar-foo = FLAP %reg333:bar<imp-def> Finally, replace the TargetRegisterInfo pointer argument with a reference to indicate that it cannot be NULL. llvm-svn: 105358		2010-06-02 22:47:25 +00:00
