Hi, I have noticed that scan_expr_access passes all the expressions it gets to get_ref_base_and_extent even when we are really only interested in memory accesses. So bail out when the expression is something clearly uninteresting. Bootstrapped and tested on x86_64-linux. OK for master? Thanks, Martin gcc/ChangeLog: 2021-12-14 Martin Jambor <mjambor@suse.cz> * ipa-sra.c (scan_expr_access): Bail out early if expr is something we clearly do not need to pass to get_ref_base_and_extent. --- gcc/ipa-sra.cc | 5 +++++ 1 file changed, 5 insertions(+)
