References debug_set_count(), debug_type_masks, debug_type_names, df_set_names, DINFO_TYPE_MAX, DINFO_TYPE_NONE, gcc_assert, and i.

◆ debug_set_to_format()

enum debug_info_type debug_set_to_format ( uint32_t debug_info_set)
extern
Get enum debug_info_type of the specified debug format, for error messages.
Can be used only for individual debug format types.

void strip_off_ending ( char * name,
int len )
extern
Strip off a legitimate source ending from the input string NAME of
length LEN.  Rather than having to know the names used by all of
