Log:
if possible use non-conservative liveness analysis: if the block
contains no
non-gc ptrs that are not typeptrs (which are immortal anyway) we can stop
considering a variable to be live when it is no longer used in the
rest of the
block.
My head hurts at so many not's.
Can you express this with less negations?
Should not be unimpossible :-)
of course not. just remove pairs of no/not :-)
"use conservative liveness analysis only if necessary: if the block
contains non-gc ptrs that are not typeptrs (which are immortal anyway,
so we don't have to consider them at all) we have to consider a variable
to be live even when it is no longer used in the rest of the block."
Cheers,
