Allow back-ends to be able to do custom validations on params.
This patch adds the ability for backends to add custom constrains to the param
values by defining a new hook option_validate_param.
This hook is invoked on every set_param_value which allows the back-end to
ensure that the parameters are always within it's desired state.
gcc/
* params.c (set_param_value):
