reid 2002/05/18 09:22:11 PDT Modified files: lib Prelude.hs lib/exts Foreign.hs Int.hs Word.hs src builtin.c connect.h ffi.c iomonad.c storage.c storage.h type.c Log: Added many of the ffi types (FunPtr, Ptr, etc) to Hugs and wired the {Int,Word}{8,16,32,64} types more firmly into Prelude/compiler We still lack ForeignPtr. What is trivial for GHC with its threads and all the rest of it is a scary proposition for the rest of us. (Specifically, I don't know if it is safe to start evaluating finalizers at all places that the GC might be invoked. Maybe the eval function could be changed to consult a list of finalizers now and then - that would be somewhat gross but safe.) The 64 bit arithmetic types lack any operations. Next step: update the code generation part of ffi, implement the currently unsupported foreign import decl and see if I can port the foreign export dynamic (or whatever it is called) sparc code from GHCi into Hugs.

There's several static checks still failing. They're all of the form: import Prelude(foo) foo = 42 This is legal Haskell code because no-one refers to foo but adding a reference to foo should elicit an error message and doesn't seem to. I haven't explored this any further because Sigbjorn's been in this recently so he'll understand the letter of the law, etc. better than I do. (What I think should be done is duplicate the checks and make one of them a correct name clash (no reference) and one an incorrect class (ambiguity does arise).)

So, the user spots the obvious typo in the Foo module, changing it to module Foo where { import BrassMonkey; } However, doing a :reload still caused BrassMoney to be searched for, with equally miserable results. The only way to purge the bogus module from the stack is to do a :load. This commit fixes this, giving :reload the desired behaviour.

Resolved by disabling the peephole optimisation that transformed "LOAD x;EVAL" into "LEVAL x" (see asEVAL() comment for more.) If this proves to be too much of a killer performance-wise, a more fine-grained solution is possible.
