WebTarget Hook: void TARGET_CALL_ARGS (rtx, tree) While generating RTL for a function call, this target hook is invoked once for each argument passed to the function, either a register returned by TARGET_FUNCTION_ARG or a memory location. It is called just before the point where argument registers are stored. WebThe argument ap is the va_list ap initialized by va_start(). Each call to va_arg() modifies ap so that the next call returns the next argument. The argument type is a type name specified so that the type of a pointer to an object that has the specified type can be obtained simply by adding a * to type. The first use of the va_arg() macro after ...
