Implying -fcaller-saves seems better to me, since "-O -fuse-caller-save"
looks like it should enable the new optimisation. It's not my c

Hmm, is that just because -fcaller-saves is -O2 and above?
For -O1, after adding -fcaller-saves the optimization triggers, and the
test-cases passes.
For -O0, adding -fcaller-saves doesn't make a difference, the optimization
doesn't trigger.
If so,

I've updated the fuse-caller-save patch series to model non-callee call clobbers

Richard,
this patch enables the fuse-caller-save optimization for MIPS.
It adds the $6 clobber in CALL_INSN_FUNCTION_USAGE when required, and s
