--- Comment #5 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
--enable-checking=release did not help much. Attached example still compiles
3.5 s. verify parts disappeared from profile, but generic_simplify are still
there:
11.20% cc1 cc1 [.] operand_compare::operand_equal_p
4.32% cc1 cc1 [.] wide_int_to_tree_1
4.23% cc1 cc1 [.] fold_binary_loc

3.64% cc1 cc1 [.] generic_simplify_EQ_EXPR
3.62% cc1 cc1 [.] tree_strip_nop_conversions

And I also see hangups when building linux-4.19, this time on x86_64 as well.
Will try to extract non-minimized example.
