nsz at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |nsz at gcc dot gnu.org --- Comment #13 from nsz at gcc dot gnu.org --- this option allows on <=gcc-7 to see all global identifiers (types, builtins, etc) that the compiler predefines, currently i don't see a way to do that for c. e.g. currently there is now way to tell what _FloatN variants gcc understands, even though -fdump-translation-unit with empty tu worked for it reliably previously. (i guess i can attach gdb to cc1 and hope there is enough debug info in cc1 to print things from gcc internal data structures.. but that's not exactly userfriendly)
