* OK, after changing to use liveIn/liveOut instead of IDEFs,
...
to avoid redundant mov out3=r44 type instructions, we need to
tell the register allocator the truth about out? registers.
FIXME: unfortunately, since the list of allocatable registers is immutable,
we can't simply 'delete r127' from the allocation order, say, if 'out0' is
used. The only correct thing we can do is have a linear order of regs:
out7, out6 ... out2, out1, out0, r32, r33, r34 ... r126, r127
and slide a 'window' of 96 registers along this line, depending on how many
of the out? regs a function actually uses. The only downside of this is
that the out? registers will be allocated _first_, which makes the
resulting assembly ugly. :( Note this in the README. Hope this gets fixed
soon. :) (note the 3rd person speech there)

Fix a minor bug (ORo didn't mark that it set CR0).
...
Refactor how . instructions are handled. In particular, instead of passing
the RC flag all the way up the inheritance hierarchy, just make a new tblgen
class 'DOT' which can be added to an instruction definition.
For example, instead of this:
-def AND : XForm_6<31, 28, 0, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
-let Defs = [CR0] in
-def ANDo : XForm_6<31, 28, 1, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
- "and. $rA, $rS, $rB">;
We now have this:
+def AND : XForm_6<31, 28, 0, 0, (ops GPRC:$rA, GPRC:$rS, GPRC:$rB),
"and $rA, $rS, $rB">;

* clean up immediates (we use 14, 22 and 64 bit immediates now. sane.)
* fold r0/f0/f1 registers into comparisons against 0/0.0/1.0
* fix nasty thinko - didn't use two-address form of conditional add
for extending bools to integers, so occasionally there would be
garbage in the result. it's amazing how often zeros are just
sitting around in registers ;) - this should fix a bunch of tests.

Assorted fixes:
...
* Stop being pessimistic about output register allocation
* Start to handle function descriptors: compute target GPs and so on
when doing indirect calls etc. Not there yet, though. For the moment,
we try to use _indirect_ branches wherever possible, to stress test
function descriptors.
* FP divide-by-zero should work now
* add varargs (it doesn't work, though)
At this point, all of SingleSource passes (modulo C++ tests that are due
to issues with the CFE, see note in the README.) Much of MultiSource also
passes although there's still a ton of bugs around. Something for me to
work on tomorrow, then. :)

Fix a problem where the PPC backend lost track of the fact that it had
...
to save and restore the LR register on entry and exit of a leaf function
that needed to access globals or the constant pool. This should hopefully
fix oscar from sending the PPC tester spinning out of control.

Fix volatile load/store of pointers. Consider this testcase:
...
void %test(int** %P) {
%A = volatile load int** %P
ret void
}
void %test2(int*** %Q) {
%P = load int*** %Q
volatile store int** %P, int*** %Q
ret void
}
instead of emitting:
void test(int **l1_P) {
int *l2_A;
l2_A = (int **((volatile int **)l1_P));
return;
}
void test2(int ***l2_Q) {
int **l1_P;
l1_P = *l2_Q;
*((volatile int ***)l2_Q) = l1_P;
return;
}
... which is loading/storing volatile pointers, not through volatile pointers,
emit this (which is right):
void test(int **l1_P) {
int *l3_A;
l3_A = *((int * volatile*)l1_P);
return;
}
void test2(int ***l2_Q) {
int **l1_P;
l1_P = *l2_Q;
*((int ** volatile*)l2_Q) = l1_P;
return;
}

so, if you beat on it, you too can talk emacs into having a sane indenting policy... Also, optimize many function calls with pc-relative calls (partial prologue skipping for that case coming soon), try to fix the random jumps to strange places problem by pesimizing div et. al. register usage and fixing up GP before using, some calling convention tweaks, and make frame pointer unallocatable (not strickly necessary, but let's go for correctness first)

Implement Regression/CodeGen/X86/rotate.ll: emit rotate instructions (which
...
typically cost 1 cycle) instead of shld/shrd instruction (which are typically
6 or more cycles). This also saves code space.
For example, instead of emitting:
rotr:
mov %EAX, DWORD PTR [%ESP + 4]
mov %CL, BYTE PTR [%ESP + 8]
shrd %EAX, %EAX, %CL
ret
rotli:
mov %EAX, DWORD PTR [%ESP + 4]
shrd %EAX, %EAX, 27
ret
Emit:
rotr32:
mov %CL, BYTE PTR [%ESP + 8]
mov %EAX, DWORD PTR [%ESP + 4]
ror %EAX, %CL
ret
rotli32:
mov %EAX, DWORD PTR [%ESP + 4]
ror %EAX, 27
ret
We also emit byte rotate instructions which do not have a sh[lr]d counterpart
at all.

Fix a problem where probing for addressing modes caused expressions to be
...
emitted too early. In particular, this fixes
Regression/CodeGen/X86/regpressure.ll:regpressure3.
This also improves the 2nd basic block in 164.gzip:flush_block, which went from
.LBBflush_block_1: # loopentry.1.i
movzx %EAX, WORD PTR [dyn_ltree + 20]
movzx %ECX, WORD PTR [dyn_ltree + 16]
mov DWORD PTR [%ESP + 32], %ECX
movzx %ECX, WORD PTR [dyn_ltree + 12]
movzx %EDX, WORD PTR [dyn_ltree + 8]
movzx %EBX, WORD PTR [dyn_ltree + 4]
mov DWORD PTR [%ESP + 36], %EBX
movzx %EBX, WORD PTR [dyn_ltree]
add DWORD PTR [%ESP + 36], %EBX
add %EDX, DWORD PTR [%ESP + 36]
add %ECX, %EDX
add DWORD PTR [%ESP + 32], %ECX
add %EAX, DWORD PTR [%ESP + 32]
movzx %ECX, WORD PTR [dyn_ltree + 24]
add %EAX, %ECX
mov %ECX, 0
mov %EDX, %ECX
to
.LBBflush_block_1: # loopentry.1.i
movzx %EAX, WORD PTR [dyn_ltree]
movzx %ECX, WORD PTR [dyn_ltree + 4]
add %ECX, %EAX
movzx %EAX, WORD PTR [dyn_ltree + 8]
add %EAX, %ECX
movzx %ECX, WORD PTR [dyn_ltree + 12]
add %ECX, %EAX
movzx %EAX, WORD PTR [dyn_ltree + 16]
add %EAX, %ECX
movzx %ECX, WORD PTR [dyn_ltree + 20]
add %ECX, %EAX
movzx %EAX, WORD PTR [dyn_ltree + 24]
add %ECX, %EAX
mov %EAX, 0
mov %EDX, %EAX
... which results in less spilling in the function.
This change alone speeds up 164.gzip from 37.23s to 36.24s on apoc. The
default isel takes 37.31s.

Select [mem] += Val operations. For constants, we used to get:
mov %ECX, -32768
add %ECX, DWORD PTR [l4_match_start]
mov DWORD PTR [l4_match_start], %ECX
Now we get:
add DWORD PTR [l4_match_start], -32768
For other values we used to get:
mov %EBP, %EDI ;; because the add destroys the value
add %EBP, DWORD PTR [l4_input_len]
mov DWORD PTR [l4_input_len], %EBP
now we get:
add DWORD PTR [l4_input_len], %EDI
Both of these use less registers than the alternative, are faster and smaller.

Instead of generating stuff like this:
...
mov %ECX, %EAX
add %ECX, 32768
mov %SI, WORD PTR [2*%ECX + l13_prev]
Generate this:
mov %SI, WORD PTR [2*%ECX + l13_prev + 65536]
This occurs when you have a GEP instruction where an index is
"something + imm".
