Fix a FIXME: Select instructions on longs were miscompiled.
...
While we're at it, improve codegen of select instructions. For this
testcase:
int %test(bool %C, int %A, int %B) {
%D = select bool %C, int %A, int %B
ret int %D
}
We used to generate this code:
_test:
cmpwi cr0, r3, 0
bne .LBB_test_2 ;
.LBB_test_1: ;
b .LBB_test_3 ;
.LBB_test_2: ;
or r5, r4, r4
.LBB_test_3: ;
or r3, r5, r5
blr
Now we emit:
_test:
cmpwi cr0, r3, 0
bne .LBB_test_2 ;
.LBB_test_1: ;
or r4, r5, r5
.LBB_test_2: ;
or r3, r4, r4
blr

Substantially improve the code generated by non-folded setcc instructions.
...
In particular, instead of compiling this:
bool %test(int %A, int %B) {
%C = setlt int %A, %B
ret bool %C
}
to this:
test:
save %sp, -96, %sp
subcc %i0, %i1, %g0
bl .LBBtest_1 !
nop
ba .LBBtest_2 !
nop
.LBBtest_1: !
or %g0, 1, %i0
ba .LBBtest_3 !
nop
.LBBtest_2: !
or %g0, 0, %i0
ba .LBBtest_3 !
nop
.LBBtest_3: !
restore %g0, %g0, %g0
retl
nop
We now compile it to this:
test:
save %sp, -96, %sp
subcc %i0, %i1, %g0
or %g0, 1, %i0
bl .LBBtest_2 !
nop
.LBBtest_1: !
or %g0, %g0, %i0
.LBBtest_2: !
restore %g0, %g0, %g0
retl
nop

Set the rounding mode for the X86 FPU to 64-bits instead of 80-bits. We
...
don't support long double anyway, and this gives us FP results closer to
other targets.
This also speeds up 179.art from 41.4s to 18.32s, by eliminating a problem
with extra precision that causes an FP == comparison to fail (leading to
extra loop iterations).

Make GEPs not suck so much:

now used instead of ConstantInt::get).
