--- Comment #2 from David Binderman <dcb314 at hotmail dot com> --- (In reply to Alexander Monakov from comment #1) > How much does -fno-ipa-cp help (on gcc-8 I see incredibly deep recursion in > walk_aliased_vdefs_1 under IPA-CP analysis)? New execution time is about 8 minutes 50 seconds, so about 10 % reduction. Alias statement walking seems to consume most of the original time.
