Perhaps the situation can be improved once Rtti.Invoke (

I doubt it.
RTTI may (you need to establish if this applies to *all* cases) tell you
that "procedure Foo(a: integer)" takes 1 int param.
But it will not tell you, if this needs to be on the stack, or in a
register (or which register).
Sorry, not correct. It does: in calling convention.
The point I meant to made is: you still need to get the value into that
register, or set up the stack. That can only be done in asm
Yes, it can only be done in ASM, but the Invoke function is part of the
RTL and thus would by definition be available for all platforms
supported by FPC (even if not every platform would be available at once).

Sven
