- Updated the compiler and runtime to allow a (practically) unlimited number of function arguments. This involved changing the calling conventions of our generated C code and runtime functions, but is transparent to application developers. Program should continue to work without requiring modifications though it may be necessary to update `define-c` definitions if there are unused parameters, to prevent warnings from the C compiler. - Updated the compiler and runtime to allow a (practically) unlimited number of function arguments.
TODO: example of the above fix This involved changing the calling conventions of our generated C code and runtime functions, but is transparent to application developers. Program should continue to work without requiring modifications though it may be necessary to update `define-c` definitions if there are unused parameters, to prevent warnings from the C compiler. For example:
(define-c read-error
"(void *data, object _, int argc, object *args)"
" object port = args[1];
object filename = args[2];
object msg = args[3];
Note that no changes are a required if `(cyclone foreign)` is used to integrate with C.
