The PowerPC register mapping
0 system glue? (caller-save, volatile)
1 SP (callee-save, non-volatile)
2 AIX, powerpc64-linux:
RTOC (a strange special case)
powerpc32-linux:
reserved for use by system
3-10 args/return (caller-save, volatile)
11,12 system glue? (caller-save, volatile)
13 on 64-bit: reserved for thread state pointer
on 32-bit: (callee-save, non-volatile)
14-31 (callee-save, non-volatile)
f0 (caller-save, volatile)
f1-f13 args/return (caller-save, volatile)
f14-f31 (callee-save, non-volatile)
\tr{14}--\tr{31} are wonderful callee-save registers on all ppc OSes.
\tr{0}--\tr{12} are caller-save registers.
\tr{%f14}--\tr{%f31} are callee-save floating-point registers.
We can do the Whole Business with callee-save registers only!
