  30.  * Small utility to disassemble a memory dump of TGSI tokens.
  31.  *
  32.  * Dump can be easily obtained from gdb through the tgsi_dump.gdb helper:
  33.  *
  34.  *  (gdb) source tgsi_dump.gdb
  35.  *  (gdb) tgsi_dump state->tokens
  36.  *
  37.  * which will generate a tgsi_dump.bin file in the current directory.
