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

nop
.LBBt1_1: !
or %g0, %i2, %i0

Add some simple integer patterns. This allows us to compile this:
int %test(int %A) {
%B = add int %A, 1
%C = xor int %B, 123
ret int %C
}
into this:
test:
save -96, %sp, %sp
add %i0, 1, %l0
xor %l0, 123, %i0
restore %g0, %g0, %g0
retl
nop
for example. I guess it would make sense to add reg/reg versions too.

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
}

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
}
