For functions that use vector registers, save VRSAVE, mark used
...
registers, and update it on entry to each function, then restore it on exit.
This compiles:
void func(vfloat *a, vfloat *b, vfloat *c) {
*a = *b * *c + *c;
}
to this:
_func:
mfspr r2, 256
oris r6, r2, 49152
mtspr 256, r6
lvx v0, 0, r5
lvx v1, 0, r4
vmaddfp v0, v1, v0, v0
stvx v0, 0, r3
mtspr 256, r2
blr
GCC produces this (which has additional stack accesses):
_func:
mfspr r0,256
stw r0,-4(r1)
oris r0,r0,0xc000
mtspr 256,r0
lvx v0,0,r5
lvx v1,0,r4
lwz r12,-4(r1)
vmaddfp v0,v0,v1,v0

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.
