Accept output arguments to benchmark functions This patch adds the ability to accept output arguments to functions being benchmarked, by nesting the argument type in <> in the args directive. It includes the sincos implementation as an example, where the function would have the following args directive: ## args: double:<double *>:<double *> This simply adds a definition for a static variable whose pointer gets passed into the function, so it's not yet possible to pass something more complicated like a pre-allocated string or array. That would be a good feature to add if a function needs it. The values in the input file will map only to the input arguments. So if I had a directive like this for a function foo: ## args: int:<int *>:int:<int *> and I have a value list like this: 1, 2 3, 4 5, 6 then the function calls generated would be: foo (1, &out1, 2, &out2); foo (3, &out1, 4, &out2); foo (5, &out1, 6, &out2);
