symbols.txt

This file contains all symbols for a module, one per line.

Example line:

__dt__13mDoExt_bckAnmFv = .text:0x800DD2EC; // type:function size:0x5C scope:global align:4

Format

Numbers can be written as decimal or hexadecimal. Hexadecimal numbers must be prefixed with 0x.

Comment lines starting with // or # are permitted, but are currently not preserved when updating the file.

symbol_name = section:address; // [attributes]
  • symbol_name - The name of the symbol. (For C++, this is the mangled name, e.g. __dt__13mDoExt_bckAnmFv)
  • section - The section the symbol is in.
  • address - The address of the symbol. For DOLs, this is the absolute address (e.g. 0x80001234). For RELs, this is the section-relative address (e.g. 0x1234).

Attributes

All attributes are optional, and are separated by spaces.

  • type: The symbol type. function, object, or label.
  • size: The size of the symbol.
  • scope: The symbol's visibility. global (default), local or weak.
  • align: The symbol's alignment.
  • data: The data type used when writing disassembly. byte, 2byte, 4byte, 8byte, float, double, int, short, string, wstring, string_table, or wstring_table.
  • hidden Marked as "hidden" in the generated object. (Only used for extab)
  • force_active Marked as "exported" in the generated object, and added to FORCEACTIVE in the generated ldscript.lcf. Prevents the symbol from being deadstripped.
  • noreloc Prevents the contents of the symbol from being interpreted as addresses. Used for objects containing data that look like pointers, but aren't.
  • noexport When export_all is enabled, this excludes the symbol from being exported. Used for symbols that are affected by linker -code_merging.
  • stripped Indicates a symbol that was stripped by the linker. Used for symbols that affect the common BSS inflation bug, despite not existing in the final binary.
