Implement an important entry from README_ALTIVEC:
If an altivec predicate compare is used immediately by a branch, don't
use a (serializing) MFCR instruction to read the CR6 register, which requires
a compare to get it back to CR's. Instead, just branch on CR6 directly. :)
For example, for:
void foo2(vector float *A, vector float *B) {
if (!vec_any_eq(*A, *B))
*B = (vector float){0,0,0,0};
}
We now generate:
_foo2:
mfspr r2, 256
oris r5, r2, 12288
mtspr 256, r5
lvx v2, 0, r4
lvx v3, 0, r3
vcmpeqfp. v2, v3, v2
bne cr6, LBB1_2 ; UnifiedReturnBlock
LBB1_1: ; cond_true
vxor v2, v2, v2
stvx v2, 0, r4
mtspr 256, r2
blr
LBB1_2: ; UnifiedReturnBlock
mtspr 256, r2
blr
instead of:
_foo2:
mfspr r2, 256
oris r5, r2, 12288
mtspr 256, r5
lvx v2, 0, r4
lvx v3, 0, r3
vcmpeqfp. v2, v3, v2
mfcr r3, 2
rlwinm r3, r3, 27, 31, 31
cmpwi cr0, r3, 0
beq cr0, LBB1_2 ; UnifiedReturnBlock
LBB1_1: ; cond_true
vxor v2, v2, v2
stvx v2, 0, r4
mtspr 256, r2
blr
LBB1_2: ; UnifiedReturnBlock
mtspr 256, r2

Implement an important entry from README_ALTIVEC:
If an altivec predicate compare is used immediately by a branch, don't
use a (serializing) MFCR instruction to read the CR6 register, which requires
a compare to get it back to CR's. Instead, just branch on CR6 directly. :)
For example, for:
void foo2(vector float *A, vector float *B) {
if (!vec_any_eq(*A, *B))
*B = (vector float){0,0,0,0};
}
We now generate:
_foo2:
mfspr r2, 256
oris r5, r2, 12288
mtspr 256, r5
lvx v2, 0, r4
lvx v3, 0, r3
vcmpeqfp. v2, v3, v2
bne cr6, LBB1_2 ; UnifiedReturnBlock
LBB1_1: ; cond_true
vxor v2, v2, v2
stvx v2, 0, r4
mtspr 256, r2
blr
LBB1_2: ; UnifiedReturnBlock
mtspr 256, r2
blr
instead of:
_foo2:
mfspr r2, 256
oris r5, r2, 12288
mtspr 256, r5
lvx v2, 0, r4
lvx v3, 0, r3
vcmpeqfp. v2, v3, v2
mfcr r3, 2
rlwinm r3, r3, 27, 31, 31
cmpwi cr0, r3, 0
beq cr0, LBB1_2 ; UnifiedReturnBlock
LBB1_1: ; cond_true

stvx v2, 0, r4

split out an encoder for memri operands, allowing a relocation to be plopped
into the immediate field. This allows us to encode stuff like this:
lbz r3, lo16(__ZL4init)(r4) ; globalopt.cpp:5
; encoding: [0x88,0x64,A,A]
; fixup A - offset: 0, value: lo16(__ZL4init), kind: fixup_ppc_lo16
stw r3, lo16(__ZL1s)(r5) ; globalopt.cpp:6
; encoding: [0x90,0x65,A,A]
; fixup A - offset: 0, value: lo16(__ZL1s), kind: fixup_ppc_lo16
With this, we should have a completely function MCCodeEmitter for PPC, wewt.

Change instruction description to split OperandList into OutOperandList and

"add{l} {$src2, $dst|$dst, $src2}",

split out an encoder for memri operands, allowing a relocation to be plopped
into the immediate field. This allows us to encode stuff like this:
lbz r3, lo16(__ZL4init)(r4) ; globalopt.cpp:5
; encoding: [0x88,0x64,A,A]
; fixup A - offset: 0, value: lo16(__ZL4init), kind: fixup_ppc_lo16
stw r3, lo16(__ZL1s)(r5) ; globalopt.cpp:6
; encoding: [0x90,0x65,A,A]
; fixup A - offset: 0, value: lo16(__ZL1s), kind: fixup_ppc_lo16
With this, we should have a completely function MCCodeEmitter for PPC, wewt.

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:

lis r2,ha16(_Y)
ori r0,r0,61680
sldi r0,r0,16

When possible, custom lower 32-bit SINT_TO_FP to this:
_foo2:
extsw r2, r3
std r2, -8(r1)
lfd f0, -8(r1)
fcfid f0, f0
frsp f1, f0
blr
instead of this:
_foo2:
lis r2, ha16(LCPI2_0)
lis r4, 17200
xoris r3, r3, 32768
stw r3, -4(r1)
stw r4, -8(r1)
lfs f0, lo16(LCPI2_0)(r2)
lfd f1, -8(r1)
fsub f0, f1, f0
frsp f1, f0
blr
This speeds up Misc/pi from 2.44s->2.09s with LLC and from 3.01->2.18s
with llcbeta (16.7% and 38.1% respectively).
