4ecc8077ce Realised that my optimisation for the usage checking had the condition the wrong way round 
This explains why all the usage tests began to fail...

759bc06a53 Fixed the type inference for operators 
The previous system followed Jim Moores' description, which turns out to not be how KRoC does it, and different enough that lots of existing occam code was failing.

The new system makes two changes.  First, if there is only one suitable operator, given the types (taking Infer to be a wild-card) then it uses that operator, and can usually settle any remaining Infers.  Second, it uses the type context to narrow down the operators to only those that have a matching return type.  These changes seem enough to compile a lot of the trickier types.

4add133d5b Made the size of INT in occam be based on the size of void* in C 
I also stopped there being separate sizes for C and C++ since that wasn't supported properly in the compiler anyway.

f36543d067 Fixed the dereference-inference for mobiles 
The new system works by inserting code in the processing of all AST elements that directly contain a variable.  If the variable needs to be dereferenced, it is.  This only happens outside variables, and when a variable is subscripted.  I did try putting this processing in doVariable, but then odd double-dereferences began to crop up, so I realised the processing has to happen outside the variable.  It seems to pass cgtest85 fine, which it was having lots of trouble with before.

b0faa0e387 Fixed the sizes for mobile arrays of mobile arrays 
The pass was folding the two arrays together, then digging too far into the dimensions of the outer array, rather than looking at the dimensions of the inner array.

f909c6fd03 Fixed external calls so that passing mobile arrays to and from external calls now works 2009-04-16 18:29:14 +00:00

19cd8085d2 Fixed the abbreviation modes of claimed channels a bit 
This doesn't solve the problem (see #95), but it at least properly confines the problem to shared channel bundles, rather than affecting shared normal channels too.

ea2d00355c Changed findAllProcess to be much more efficient 
Previously, it was finding the processes in the flow-graph, then using the routes to find the process in question, then calling the examination function on that process.  For large flow trees, the cost of traversing all the routes (to all A.Process!) was too high.

Now it find the processes in the AST (so that it only traverses the AST once) then zips any found processes with the flow-graph (using the route IDs) with Map.intersectionWith, which is much faster.
