Hi all, I'm playing with frontend creation, and i got through funny behaviour about -fdump-passes (and other common options) with gcc 14.1 and gcc 14.2. Raw facts: $install/bin/gcc -o out mysource.myext -fdump-passes Does NOT dump passes, even if i copy fdump-passes option def in my lang.opt. gdb $install/bin/gcc / run -o out mysource.myext -fdump-passes Dumps passes as expected if i follow inferior (set follow-fork-mode child / set detach-on-fork off, unsensitive to set disable-randomization). Does not dump passes if not following inferiors. $install/libexec/[...]/myfrontend -o out mysource.myext -fdump-passes Dumps passes as expected. All that raises some questions: - what is the expected behaviour when invoking gcc? (in my understanding, it should dump). - is there a known reason to explain this behaviour mismatch under gdb depending on gdb's configuration? - is there anything i should do to support common options in my frontend? I can provide more informations about my frontend, but i do nothing fancy in here, that's just to learn how to code in GENERIC. Thanks for having read until this point. Regards
