I ran yesterday linux-user SPEC06 benchmarks from your tcg-life branch.
I do see perf regressions for two workloads (sjeng and xalancbmk).
With perf(1) I see liveness_pass* are at 0.00%, so I wonder: is it
possible that the emitted code isn't quite the same?
Everything that I checked by hand was the same, but it's possible.
It's a tedious process. You'd definitely want to turn off ASR.
My current branch has __attribute__((noreturn)) added to all of the liveness passes, so
that they don't get folded into tcg_gen_code. But I still would expect 0%.
