I started to look into changing the callbacks in macroexp.h to use gdb::function_view. However, I noticed that the passed lookup function was always `standard_macro_lookup`, which looks up a macro in a `macro_scope` object. Since that doesn't look like a very useful abstraction, it would be simpler to just pass the scope around and have the various functions call standard_macro_lookup themselves. This is what this patch does. gdb/ChangeLog: * macroexp.h (macro_lookup_ftype): Remove. (macro_expand, macro_expand_once, macro_expand_next): Remove lookup function parameters, add scope parameter. * macroexp.c (scan, substitute_args, expand, maybe_expand, macro_expand, macro_expand_once, macro_expand_next): Likewise. * macroscope.h (standard_macro_lookup): Change parameter type to macro_scope. * macroscope.c (standard_macro_lookup): Likewise. * c-exp.y (lex_one_token): Update. * macrocmd.c (macro_expand_command): Likewise. (macro_expand_once_command): Likewise. Change-Id: Id2431b1489359e1b0274dc2b81e5ea5d225d730c
