Missing symbols
BenoitRen edited this page 8 months ago
While the majority of symbols is present in the DWARF debug data, it's incomplete.
Structs
The majority of structs were anonymous. This means that they were defined without a tag, and used through type names, which are not part of the symbol table.
The following type names were made up for tagless structs:
- short_chars
- int_shorts
- int_chars
- ushort_uchars
- uint_ushorts
- uint_uchars
- sprite_data
- sprite_pattern
- game_info
- time_data
- score_data
- sprite_status
- sprite_statuses
- aset_info
- asetz_info
- bmp_info
- edit_info
- edit_info_array
- map_info
- palette_part
- sprite_patterns_sp
- sprite_status_sp
- damage_info
- hane_info
- zoom_info
- move_tbl
- bwrt_info
- tile_changes
- tile_change_data
tagPALETTEENTRY and tagPOINT had their tag saved, but not their name. These are actually from the Windows API, and their default names as defined in the headers are PALETTEENTRY and POINT, respectively.
Unions
All unions were anonymous. This means that they were defined without a tag, and used through type names, which are not part of the symbol table.
The following type names were made up:
- short_union
- int_union
- ushort_union
- uint_union
Parameters
Unused parameters are not added to the symbol table. However, they did affect the stack during compilation, which is how we can tell that they were present.

Labels
Labels are not added to the symbol table. They've been made up using non-descriptive names like label1, label2,...
