Super-H - Debugging with GDB

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

regs: Show the values of all Super-H registers.
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.
