add andn/orn/xorn patterns. This allows us to compile this:
long %test(ubyte, short, long %X, long %Y) {
%A = xor long %X, -1
%B = and long %Y, %A
ret long %B
}
to this:
test:
save -96, %sp, %sp
andn %i4, %i2, %i0
andn %i5, %i3, %i1
restore %g0, %g0, %g0
retl
nop
instead of this:
test:
save -96, %sp, %sp
xor %i2, -1, %l0
xor %i3, -1, %l1
and %i4, %l0, %i0
and %i5, %l1, %i1
restore %g0, %g0, %g0
retl
nop
The simpleisel emits: :(
test:
save -96, %sp, %sp
or %g0, -1, %l0
or %g0, -1, %l0
or %g0, -1, %l0
or %g0, -1, %l1
xor %i2, %l0, %l0
xor %i3, %l1, %l1
and %i4, %l0, %i0
and %i5, %l1, %i1
restore %g0, %g0, %g0
retl
nop
