Edwin Brady d5377be628 New language-dependent FFI ... More documentation to follow, but in brief: - IO is now a synonym of IO' FFI_C - IO' is parameterised over an ffi description, which explains which types are allowed in foreign calls, and what a foreign call target is (in C, that's a String giving the function name, for example) - New function "foreign" for building a foreign call, given an ffi description, call target, and the type of the call. The type is enough to build a structure which the compiler uses to generate the call. The type of main now needs to be IO' x (), where x can be any FFI description. There is currently only an ffi description for C; Javascript will follow. FFI_C should also work for the llvm backend (it's really about the calling convention, not the backend specifically). Small changes will be needed to the various code generators.		2015-01-17 19:08:33 +00:00
