I also think it would be very useful.
BTW, MELT has also such a feature (which proved extremely useful in daily use,
so I am sure that if something existed in GCC it would help a lot many GCC
developers),
but it is simpler because MELT call frames are
explicit (linked) C struct-s (generated by the MELT translator), and there is
some location slot inside them. So MELT can output backtraces like e.g.
SHORT BACKTRACE[#0] warmelt-first.melt:2809: MELT CHECK:
meltmod__warmelt_first__initialmeltchunk_39 {putroutconst
constnull.drout_3199__INITVALUE_EXPORTER#0};
#1:_ warmelt-first.melt:2801:/ initchunk
#2:_ melt-runtime.c:9000:: meltgc_start_module_by_index before starting #1
/usr/src/Lang/basile-melt-gcc/gcc/melt/generated/warmelt-first
#3:_ melt-runtime.c:9038:: meltgc_start_all_new_modules before starting #1
module
/usr/src/Lang/_Obj_Melt_Basile/gcc/meltbuild-stage0-dynamic/warmelt-first.meltmod-675464a27b5d1fd9709f280cd71315ef.dynami
#4:_ melt-runtime.c:9675:: meltgc_load_modules_and_do_mode before loading
curmod meltbuild-stage0-dynamic/warmelt-modes.dynamic
Cheers.
