2010-11-02Don't try to split weird critical edges that really aren't:Jakob Stoklund Olesen
BB#1: derived from LLVM BB %bb.nph28 Live Ins: %AL Predecessors according to CFG: BB#0 TEST8rr %reg16384<kill>, %reg16384, %EFLAGS<imp-def>; GR8:%reg16384 JNE_4 <BB#2>, %EFLAGS<imp-use,kill> JMP_4 <BB#2> Successors according to CFG: BB#2 BB#2 These double CFG edges only ever occur in bugpoint-generated code, so there is no need to attempt something clever. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117992 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-01Be more precise about verifying missing kill flags.Jakob Stoklund Olesen
It is legal for an instruction to have two operands using the same register, only one a kill. This is interpreted as a kill. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117981 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-01When inserting copies during splitting, always use the parent register as theJakob Stoklund Olesen
source, and let rewrite() clean it up. This way, kill flags on the inserted copies are fixed as well during rewrite(). We can't just assume that all the copies we insert are going to be kills since critical edges into loop headers sometimes require both source and dest to be live out of a block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117980 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-01Add kill flag verification.Jakob Stoklund Olesen
At least X86FloatingPoint requires correct kill flags after register allocation, and targets using register scavenging benefit. Conservative kill flags are not enough. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117960 91177308-0d34-0410-b5e6-96231b3b80d8
