Ahmed Bougacha 54b7d334c7 [MachineCSE] Clear kill-flag on registers imp-def'd by the CSE'd instruction. ... Go through implicit defs of CSMI and MI, and clear the kill flags on their uses in all the instructions between CSMI and MI. We might have made some of the kill flags redundant, consider: subs ... %NZCV<imp-def> <- CSMI csinc ... %NZCV<imp-use,kill> <- this kill flag isn't valid anymore subs ... %NZCV<imp-def> <- MI, to be eliminated csinc ... %NZCV<imp-use,kill> Since we eliminated MI, and reused a register imp-def'd by CSMI (here %NZCV), that register, if it was killed before MI, should have that kill flag removed, because it's lifetime was extended. Also, add an exhaustive testcase for the motivating example. Reviewed by: Juergen Ributzka <juergen@apple.com> llvm-svn: 223133		2014-12-02 18:09:51 +00:00
