Some call details are exposed in the front ends (see targetm.calls.promote_prototypes called from c-typeck.c, for example). I think that's too early; the front end should be generating IR for calls that reflects the language semantics, and architecture details should be exposed later (quite likely on GIMPLE). -- Joseph S.
