set powerpc soft-float
show powerpc soft-float
- Force gdb to use (or not use) a software floating point calling

- Force gdb to use the specified calling convention for vector
arguments and return values. The valid options are `auto';
`generic', to avoid vector registers even if they are present;

registers. By default, gdb selects the calling convention
based on the selected architecture and the provided executable file.
