tc supports these two options to decide how many $s? and $t? there are on the mips we target. This is a cool feature to exercise the regallocation. But it would be even cooler if Nolimips supported these two options too, since that would make it possible to check that tc is not cheating, using $s7 when --callee-save=0.

src/tc/trunk % src/tc --callee-save=0 --caller-save=3 --target-display - CPU (12) Arguments (4): $a0, $a1, $a2, $a3 Caller Save (3): $t0 $t1 $t2 Callee Save (0): Special (5): $fp $ra $sp $v0 $zero src/tc/trunk % src/tc --target-display - nostromo 15:47 CPU (27) Arguments (4): $a0, $a1, $a2, $a3 Caller Save (10): $t0 $t1 $t2 $t3 $t4 $t5 $t6 $t7 $t8 $t9 Callee Save (8): $s0 $s1 $s2 $s3 $s4 $s5 $s6 $s7 Special (5): $fp $ra $sp $v0 $zero

Je voudrais insister sur les bénéfices de telles options !
