/* List the order in which to allocate registers. Each register must be
listed once, even those in FIXED_REGISTERS.
We allocate in the following order:
$f1 (nonsaved floating-point register)
$f10-$f15 (likewise)
$f22-$f30 (likewise)
$f21-$f16 (likewise, but input args)
$f0 (nonsaved, but return value)
$f2-$f9 (saved floating-point registers)
$1 (nonsaved integer registers)
$22-$25 (likewise)
$28 (likewise)
$0 (likewise, but return value)
$21-$16 (likewise, but input args)
$27 (procedure value in OSF, nonsaved in NT)
$2-$8 (saved integer registers)
$9-$14 (saved integer registers)
$26 (return PC)
$15 (frame pointer)
$29 (global pointer)
$30, $31, $f31 (stack pointer and always zero/ap & fp) */
