--- Comment #6 from Jan Hubicka <hubicka at gcc dot gnu.org> --- Created attachment 57427 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57427&action=edit patch The patch makes compilation to finish in reasonable time. I ended up in need to dropping DISREGARD_INLINE_LIMITS in late inlining for functions with self recursive always inlines, since these grow large quick and even non-recursive inlining is too slow. We also end up with quite ugly diagnostics of form: tt.c:13:1: error: inlining failed in call to ‘always_inline’ ‘f1’: --param max-inline-insns-auto limit reached 13 | f1 (void) | ^~ tt.c:17:3: note: called from here 17 | f1 (); | ^~~~~ tt.c:6:1: error: inlining failed in call to ‘always_inline’ ‘f0’: --param max-inline-insns-auto limit reached 6 | f0 (void) | ^~ tt.c:16:3: note: called from here 16 | f0 (); | ^~~~~ tt.c:13:1: error: inlining failed in call to ‘always_inline’ ‘f1’: --param max-inline-insns-auto limit reached 13 | f1 (void) | ^~ tt.c:15:3: note: called from here 15 | f1 (); | ^~~~~ In function ‘f1’, inlined from ‘f0’ at tt.c:8:3, which is quite large so I can not add it to a testuiste. I will see if I can reduce this even more.
