[LLVMdev] Live intervals and aliasing registers problem
...ly
partially dead. This same situation arises even when the parameters
are not live-ins to the function, all it takes is two registers which
alias a third to have overlapping live ranges, such as when the
following code is compiled.
define void @_Z3foov() {
entry:
%tmp1 = tail call float @_Z3onev( ) ; <float> [#uses=2]
%tmp2 = tail call float @_Z3twov( ) ; <float> [#uses=2]
%tmp5 = fcmp olt float %tmp1, %tmp2 ; <i1> [#uses=1]
%retval = select i1 %tmp5, float %tmp1, float %tmp2 ; <float>
[#uses=0]
ret void
}
Does the fact that V4R0 is considered live-in mea...
