[LLVMdev] complex branching generation
LLVM seems to be generating way too complex of branching based on the
short-circuit optimization. The code in question is as follows:
define void @ test_fc_while_and(float %x, float %y, float addrspace(11)*
%result) nounwind {
entry:
%tobool3 = fcmp une float %x, 0.000000e+000 ; <i1>
[#uses=1]
%tobool24 = fcmp une float %y, 0.000000e+000 ; <i1>
[#uses=2]
%or.cond5 = and i1 %tobool3, %tobool24 ; <i1> [#uses=1]
br i1 %or.cond5, label %bb.nph, label %whileexit...
