  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.
