   9  * Memory addresses for segments. Ideally, this header file would not be
  10  * needed, and the addresses would be defined in sm64.ld and linker-inserted
  11  * into C code. However, there are some cases where that would not match, where
  12  * addresses are loaded using lui/ori rather than lui/addiu.
  13  * To avoid duplication, this file is included from sm64.ld. We make sure not
  14  * to cast the addresses to pointers in this file, since that would be invalid
  15  * linker script syntax.
