0ed18c933f Fixed pullUp to not pull up list expressions 
This patch looks like I removed the wrong line above, but it was identical to the line I actually removed, so the patch is fine, it just looks odd.

b8b7e04b7c Refactor literal and subscript checks. 
For both of these, we already examine all the places they occur for other
reasons, so there's no good reason to do a separate traversal for them.

60ca26128c More occam typechecks: input/output items, replicators, choices. 
Various infrastructure too to support these.

Doing A.ForEach raised an interesting question: what does it work over?  In
plain occam it'd just be arrays, but it should obviously work for lists too.
This suggests that Size and Subscript should work on lists as well, since
ForEach will be implemented in terms of them. I've therefore introduced the
idea of a "sequence" class of types.

6ab4a9923f Implement expression typechecking for occam. 
There's obviously some overlap with the Rain typechecker here. I've tried to
cover everything in the AST that could potentially be bound into occam at some
point in the future, even if the occam parser doesn't support it yet (so
this'll do checks for Concat and mobile allocation, for example).

388f2f38a6 plainSubscriptType doesn't really need to know what the subscript is. 2008-03-22 00:53:46 +00:00

56de093739 Add isScalarType. 2008-03-22 00:53:13 +00:00

321e52dd65 Add checkDepthM. 
This is like applyDepthM, but for functions that don't want to change the AST.
(There's probably a more efficient way of implementing this.)

8b2568264d Add more utility functions along the lines of defineConst. 
These let you define various sorts of name in the initial state of a pass test.

8b5233ba47 Add ShowCode instances for A.Name. 2008-03-22 00:42:00 +00:00

e23a12c71d Don't resolve user types until after type checking. 
This is important -- a user type defined as INT in occam must not be treated
the same as INT when typechecking.

9cea36257e Make functionsToProcs depend on expressionTypesChecked. 
I think in general typechecking needs to happen before any other pass runs,
else the user's likely to get rather confusing error messages.

cfc5b18e3e Don't show the state when a pass unexpectedly succeeds. 
This used not to be a problem, but there's now quite a lot of stuff predefined
in the state when testing the typechecker, so it tends to obscure the real
error...

7c4275116e Various cleanups to AST.hs.
