For each loop, keep track of all the IV expressions inserted indexed by
...
stride. For a set of uses of the IV of a stride which is a multiple
of another stride, do not insert a new IV expression. Rather, reuse the
previous IV and rewrite the uses as uses of IV expression multiplied by
the factor.
e.g.
x = 0 ...; x ++
y = 0 ...; y += 4
then use of y can be rewritten as use of 4*x for x86.

Several big changes:
...
1. Use flags on the instructions in the .td file to indicate the PPC970 unit
type instead of a table in the .cpp file. Much cleaner.
2. Change the hazard recognizer to build d-groups according to the actual
algorithm used, not my flawed understanding of it.
3. Model "must be in the first slot" and "must be the only instr in a group"
accurately.

As a pending queue data structure to keep track of instructions whose
...
operands have all issued, but whose results are not yet available. This
allows us to compile:
int G;
int test(int A, int B, int* P) {
return (G+A)*(B+1);
}
to:
_test:
lis r2, ha16(L_G$non_lazy_ptr)
addi r4, r4, 1
lwz r2, lo16(L_G$non_lazy_ptr)(r2)
lwz r2, 0(r2)
add r2, r2, r3
mullw r3, r2, r4
blr
instead of this, which has a stall between the lis/lwz:
_test:
lis r2, ha16(L_G$non_lazy_ptr)
lwz r2, lo16(L_G$non_lazy_ptr)(r2)
addi r4, r4, 1

2.5GHz G5. This also enables future code sharing between Dom and PostDom

Teach the latency scheduler some new tricks. In particular, to break ties,
...
keep track of a sense of "mobility", i.e. how many other nodes scheduling one
node will free up. For something like this:
float testadd(float *X, float *Y, float *Z, float *W, float *V) {
return (*X+*Y)*(*Z+*W)+*V;
}
For example, this makes us schedule *X then *Y, not *X then *Z. The former
allows us to issue the add, the later only lets us issue other loads.
This turns the above code from this:
_testadd:
lfs f0, 0(r3)
lfs f1, 0(r6)
lfs f2, 0(r4)
lfs f3, 0(r5)
fadds f0, f0, f2
fadds f1, f3, f1
lfs f2, 0(r7)
fmadds f1, f0, f1, f2
blr
into this:
_testadd:
lfs f0, 0(r6)
lfs f1, 0(r5)
fadds f0, f1, f0
lfs f1, 0(r4)
lfs f2, 0(r3)

the pointer is known to come from either a global variable, alloca or

P = malloc(28);
memset(P, 0, 28);
into explicit stores on PPC instead of a memset call.

MEMSET / MEMCPY lowering bugs: we can't issue a single WORD / DWORD version of
...
rep/stos and rep/mov if the count is not a constant. We could do
rep/stosl; and $count, 3; rep/stosb
For now, I will lower them to memset / memcpy calls. We will revisit this after
a little bit experiment.
Also need to take care of the trailing bytes even if the count is a constant.
Since the max. number of trailing bytes are 3, we will simply issue loads /
stores.
