Hi Jakub, interesting patch. I ran it over the Ada testsuite and this picked up some problems even without enabling dse-ssu. For example, "opt -inline -dse -domtree" crashes on the attached testcase.

This is my first "big" patch, please be tolerant :-) Please note that optimization is disabled by default. -Jakub -------------- next part -------------- A non-text attachment was scrubbed...
