Make symfile_add_flags and objfile->flags strongly typed
This makes these flag types be "enum flag" types. The benefit is
making use of C++'s stronger typing -- mixing the flags types by
mistake errors at compile time.
This caught one old bug in symbol_file_add_main_1 already, fixed by
this patch as well:
@@ -1318,7 +1326,7 @@ symbol_file_add_main_1 (const char *args, int from_tty, int flags)
what is frameless. */
reinit_frame_cache ();
- if ((flags & SYMFILE_NO_READ) == 0)
+ if ((add_flags & SYMFILE_NO_READ) == 0)
set_initial_language ();
}
Above, "flags" are objfile flags, not symfile_add_flags. So that was
actually checking for "flag & OBJF_PSYMTABS_READ", which has the same
value as SYMFILE_NO_READ...

Make symfile_add_flags and objfile->flags strongly typed
This makes these flag types be "enum flag" types. The benefit is
making use of C++'s stronger typing -- mixing the flags types by
mistake errors at compile time.
This caught one old bug in symbol_file_add_main_1 already, fixed by
this patch as well:
@@ -1318,7 +1326,7 @@ symbol_file_add_main_1 (const char *args, int from_tty, int flags)

- if ((flags & SYMFILE_NO_READ) == 0)
+ if ((add_flags & SYMFILE_NO_READ) == 0)

}
Above, "flags" are objfile flags, not symfile_add_flags. So that was
actually checking for "flag & OBJF_PSYMTABS_READ", which has the same
value as SYMFILE_NO_READ...
I moved the flags definitions to separate files to break circular
dependencies.
