Jakob Stoklund Olesen 53e000bac3 Better handling of dead super registers in LiveVariables. We used to do this: ... CALL ... %RAX<imp-def> ... [not using %RAX] %EAX = ..., %RAX<imp-use, kill> RET %EAX<imp-use,kill> Now we do this: CALL ... %RAX<imp-def, dead> ... [not using %RAX] %EAX = ... RET %EAX<imp-use,kill> By not artificially keeping %RAX alive, we lower register pressure a bit. The correct number of instructions for 2008-08-05-SpillerBug.ll is obviously 55, anybody can see that. Sheesh. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97838 91177308-0d34-0410-b5e6-96231b3b80d8		2010-03-05 21:49:17 +00:00
