I assume you mean a function definition rather than a function declaration. There is no immediate access to information like the number of local variables or whether a function is a leaf function. You have to look at the body of the function for that. In the middle-end of the compiler the body will be a list of GIMPLE statements. GIMPLE is very lightly documented in the internals manual. Ian
