list-call-direct-possibilities

Arguments: nil

This function returns a list of lists of descriptions which should aid in call-direct compilation. Each list represents a kind of argument or return value, and starts with a string describing what the rest of the list describes. For those descriptions which start "bad ..." the types listed will force the compilation of a call to the function to be compiled out-of-line. The other lists describe those arg/return types that are required in order to compile the call as a direct-call. These types are lisp types or specifiers; they can either be explicitly specified as the lisp type or implied by the C type of the argument or return value (see def-foreign-call and foreign-functions.htm.

See compiling.htm for general information on compiling in Allegro CL.
