First step towards V9 instructions in the V8 backend, two conditional move
patterns. This allows emission of this code:
t1:
save -96, %o6, %o6
subcc %i0, %i1, %l0
move %icc, %i0, %i2
or %g0, %i2, %i0
restore %g0, %g0, %g0
retl
nop
instead of this:
t1:
save -96, %o6, %o6
subcc %i0, %i1, %l0
be .LBBt1_2 !
nop
.LBBt1_1: !
or %g0, %i2, %i0
.LBBt1_2: !
restore %g0, %g0, %g0
retl
nop
for this:
int %t1(int %a, int %b, int %c) {
%tmp.2 = seteq int %a, %b
%tmp3 = select bool %tmp.2, int %a, int %c
ret int %tmp3
}
