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
}

To-do
|
|
-----
|
|
|
|
* Keep the address of the constant pool in a register instead of forming its
|
|
address all of the time.
|
|
* We can fold small constant offsets into the %hi/%lo references to constant
|
|
pool addresses as well.
|
|
* When in V9 mode, register allocate %icc[0-3].
