#### 21.3.12 CRIS

When configured for debugging CRIS, gdb provides the following CRIS-specific commands:

`set cris-version` ver
  Set the current CRIS version to ver, either ``10`' or ``32`'. The CRIS version affects register names and sizes. This command is useful in case autodetection of the CRIS version fails.
`show cris-version`
  Show the current CRIS version.
`set cris-dwarf2-cfi`
  Set the usage of DWARF-2 CFI for CRIS debugging. The default is ``on`'. Change to ``off`' when using `gcc-cris` whose version is below `R59`.
`show cris-dwarf2-cfi`
  Show the current state of using DWARF-2 CFI.
`set cris-mode` mode
  Set the current CRIS mode to mode. It should only be changed when debugging in guru mode, in which case it should be set to ``guru`' (the default is ``normal`').
`show cris-mode`
  Show the current CRIS mode.
