#### 21.3.10 Renesas Super-H

For the Renesas Super-H processor, GDB provides these commands:

`set sh calling-convention convention`

  Set the calling-convention used when calling functions from GDB. Allowed values are ‘`gcc`’, which is the default setting, and ‘`renesas`’. With the ‘`gcc`’ setting, functions are called using the GCC calling convention. If the DWARF-2 information of the called function specifies that the function follows the Renesas calling convention, the function is called using the Renesas calling convention. If the calling convention is set to ‘`renesas`’, the Renesas calling convention is always used, regardless of the DWARF-2 information. This can be used to override the default of ‘`gcc`’ if debug information is missing, or the compiler does not emit the DWARF-2 calling convention entry for a function.

`show sh calling-convention`

  Show the current calling convention setting.
