Minor tweak to the branch selector. When emitting a two-way branch, and if
...
we're in a single-mbb loop, make sure to emit the backwards branch as the
conditional branch instead of the uncond branch. For example, emit this:
LBBl29_z__44:
stw r9, 0(r15)
stw r9, 4(r15)
stw r9, 8(r15)
stw r9, 12(r15)
addi r15, r15, 16
addi r8, r8, 1
cmpw cr0, r8, r28
ble cr0, LBBl29_z__44
b LBBl29_z__48 *** NOT PART OF LOOP
Instead of:
LBBl29_z__44:
stw r9, 0(r15)
stw r9, 4(r15)
stw r9, 8(r15)
stw r9, 12(r15)
addi r15, r15, 16
addi r8, r8, 1
cmpw cr0, r8, r28
bgt cr0, LBBl29_z__48 *** PART OF LOOP!
b LBBl29_z__44
The former sequence has one fewer dispatch group for the loop body.

Modify the ppc backend to use two register classes for FP: F8RC and F4RC.
...
These are used to represent float and double values, and the two regclasses
contain the same physical registers.

Darwin, like many BSD systems, has a setjmp/longjmp which saves the signal mask

on setjmp calls and restores it on longjmp calls (both of which require syscalls).
This makes the calls REALLY slow. Use _setjmp/_longjmp instead. This speeds up
hexxagon from 120.31s to 15.68s: from 5.53x slower than GCC to 28% faster than GCC.

Fix a problem that Nate noticed, where spill code was not getting coallesced
...
with copies, leading to code like this:
lwz r4, 380(r1)
or r10, r4, r4 ;; Last use of r4
By teaching the PPC backend how to fold spills into copies, we now get this
code:
lwz r10, 380(r1)
wow. :)
This reduces a testcase nate sent me from 1505 instructions to 1484.
Note that this could handle FP values but doesn't currently, for reasons
mentioned in the patch

Introduce two new concepts:
...
1. Add support for defining Pattern's, which can match expressions when there
is no instruction that directly implements something. Instructions usually
implicitly define patterns.
2. Add support for defining SDNodeXForm's, which are node transformations.
This seperates the concept of a node xform out from the existing predicate
support.
Using this new stuff, we add a few instruction patterns, one for testing, and
two for OR/XOR by an arbitrary immediate.

Implement dynamic allocas correctly. In particular, because we were copying
...
directly out of R1 (without using a CopyFromReg, which uses a chain), multiple
allocas were getting CSE'd together, producing bogus code. For this:
int %foo(bool %X, int %A, int %B) {
br bool %X, label %T, label %F
F:
%G = alloca int
%H = alloca int
store int %A, int* %G
store int %B, int* %H
%R = load int* %G
ret int %R
T:
ret int 0
}
We were generating:
_foo:
stwu r1, -16(r1)
stw r31, 4(r1)
or r31, r1, r1
stw r1, 12(r31)
cmpwi cr0, r3, 0
bne cr0, .LBB_foo_2 ; T
.LBB_foo_1: ; F
li r2, 16
subf r2, r2, r1 ;; One alloca
or r1, r2, r2
or r3, r1, r1
or r1, r2, r2
or r2, r1, r1
stw r4, 0(r3)
stw r5, 0(r2)
lwz r3, 0(r3)
lwz r1, 12(r31)
lwz r31, 4(r31)
lwz r1, 0(r1)

li r3, 0
lwz r1, 12(r31)
lwz r31, 4(r31)
lwz r1, 0(r1)
blr
Now we generate:
_foo:
stwu r1, -16(r1)
stw r31, 4(r1)
or r31, r1, r1
stw r1, 12(r31)
cmpwi cr0, r3, 0

stw r4, 0(r2)
