Hello.
It's going to be almost a year Richard advised me to utilize IPA ICF
infrastructure in tree-ssa-tail-merge, currently using value numbering which
is quite hard to maintain.
Following small patch set is kick-off and I am opened for advices. Meanwhile,
I'm going to send statistics about merged basic blocks before/after the patch
set.
Patch set can bootstrap on x86_64-linux-pc and survives regression tests.
Thanks,
Martin
