[LLVMdev] Def/Kill flags for subregisters
...lackfin backend. I am
having some trouble understanding the semantics of def/kill flags on
machine operands when using subregisters.
I compile this function:
define void @i56_ls(i56 %x) nounwind {
store i56 %x, i56* @i56_s
ret void
}
And get this initial machine code:
Live Ins: %R0 %R1
%reg1025D<def> = MOVE %R1
%reg1024D<def> = MOVE %R0
%reg1026D<def> = MOVE %reg1025D
%reg1027P<def> = LOAD32imm <ga:i56_s>
%reg1028D<def> = SRLd %reg1025D, 16
%reg1029D16L<def> = EXTRACT_SUBREG %reg1026D, 1
%reg1030P<def> = ADDimm7 %reg1027P, 4
