Add some 64-bit logical ops.
Split imm16Shifted into a sext/zext form for 64-bit support.
Add some patterns for immediate formation. For example, we now compile this:
static unsigned long long Y;
void test3() {
Y = 0xF0F00F00;
}
into:
_test3:
li r2, 3840
lis r3, ha16(_Y)
xoris r2, r2, 61680
std r2, lo16(_Y)(r3)
blr
GCC produces:
_test3:
li r0,0
lis r2,ha16(_Y)
ori r0,r0,61680
sldi r0,r0,16
ori r0,r0,3840

Add some 64-bit logical ops.
Split imm16Shifted into a sext/zext form for 64-bit support.
Add some patterns for immediate formation. For example, we now compile this:
static unsigned long long Y;
void test3() {
Y = 0xF0F00F00;
}
into:
_test3:
li r2, 3840
lis r3, ha16(_Y)
xoris r2, r2, 61680
std r2, lo16(_Y)(r3)
blr
GCC produces:
_test3:
li r0,0
lis r2,ha16(_Y)
ori r0,r0,61680
sldi r0,r0,16
ori r0,r0,3840
