a416f7dac9 Fixed the occam type-checker to work with the new channel-ends, adding direction specifiers where necessary 
In actual parameters (checking against the formal type), abbreviations (checking against the inferred/specified destination type), and inputs (including inside ALTs) and outputs, direction specifiers are automatically added where needed.  With all the other changes, this seems to compile all the occam 2 cgtests, and cgtest87 (which tests directions) as well as Adam's tests so I'm fairly confident that it was the right thing to do.

4d692c8897 Fixed the occam and Rain parsers to work with the new channel-ends 
For now, I have fixed the occam parser so that it allows 1 or more direction specifiers after channel names.  So c?? is valid, and should end up being equivalent to c?, but this may need altering later.

541f7c1421 Turned the Chan type into a Chan type for full channels and a ChanEnd type for the directed ends 
This is the first patch in the series of many that implement this change throughout Tock.

Fixes #70.

2137be190b Added a PassMaker function for use when something should only be used with occam and the CCSP backend 2009-01-20 17:24:01 +00:00

ee856a0d39 Made the usage checking check if a name was marked by a SHARED pragma before issuing an error 2009-01-19 15:11:42 +00:00

8a36f6e96f Added support for parsing pragmas, for now just handling the SHARED pragma 2009-01-19 15:11:09 +00:00

f612b99a49 Added a map of name attributes (ready for things like PRAGMA SHARED) to the CompState 
This should possibly (and could in future) be combined into NameDef and the main csNames map

d3fc6a1a90 Made the size of INT vary between 16-,32- and 64-bit platforms 
Fixes #37.  The change itself was very easy, but the main problem was to then go and change everything in GenerateCTest that had been written using A.Int as a test type.

24f646f5b8 Changed if statements so that they generate a simpler if when no specs are involved 
Fixes #16.  If there are no Spec or ProcThen items in an if, a much simpler if (without gotos or similar) is generated.

949c88bb75 Added support for the canonicalisation of simple Expressions 
This seems to have fixed a couple more normal tests, and goes towards fixing the randomly failing quickcheck test (but that test is not fixed, yet)

536d0b19a6 Fixed all the failing C++CSP tests for input and output so that they now pass 2009-01-17 22:20:52 +00:00

8174e86366 Made the usage checking on PARs for plain variables ignore the variables declared inside the branches of that PAR 2009-01-17 19:05:31 +00:00

d9cfa9135d Made sure that timer variables are always considered read-only when passed around 
This fixes a usage checking problem in cgtest08 where the variable would be considered written-to in parallel because it was passed twice in parallel (and not marked as a VAL abbrev)

6f22d8a573 Stopped the pulling up of fully-resolved array expressions where one of the subscripts is a slice 
This was causing a problem in the C/C++ backends, where the slice function call was having _sizes appended to it.  So now we pull up anything that results in an array, or is a slice.

dd57fdccbd Made a small change to sort multiplied expressions into order during flattening in the usage checking 
This makes sure that y*x and x*y are both flattened into x*y, but doesn't yet solve the problem of (x*y)*z vs (y*z)*x

f7e05c2714 Made sure that the usage checking on plain variables checks anything that doesn't have a replicator in it 
This means that things like a[0][0] are once again covered by the plain variable check, which means that some more tests now pass.

b48129d4e5 Fixed some uses of Map.lookup that used the old system of it working with any monad (in GHC 6.10, it's always Maybe) 2008-11-28 11:38:06 +00:00

ce03f2ca27 Fixed the nasty hack of checking for _sizes by checking the new NameSource field instead 
To avoid problems with removing _sizes variables, we simply don't remove any nonce variables.

5bb528fbc3 Changed from using monoid (which always concatenated) to using prepending, but I'm not sure it's any faster 2008-11-24 10:41:30 +00:00

4af8845142 Changed checkUnusedVar to use the new forAnyASTStructBottomUpAccum function 2008-11-24 10:30:30 +00:00

0eab9a216d Got the forAnyASTStructBottomUpAccum function working properly, but I think list concatenation is a bit slow 2008-11-24 10:29:38 +00:00

0275615f5e Generalised CheckOptFlowM to have the accumulation mechanism, but left it largely unused for now 2008-11-21 21:04:10 +00:00

373214efb5 Renamed the forAnyAST functions to indicate their top-down nature and refactored doTree/apply slightly 2008-11-21 20:32:04 +00:00

40318ac152 Changed checkUnusedVar to an incredibly slow version using "fastListify" 
The problem is that it runs fastListify on a name's scope for every node it encounters, so something like O(M*N).  This needs fixing, obviously.

d529d78846 Added a slightly hacky fastListify function built on top of applyDepthM 2008-11-21 18:54:23 +00:00

ae7557d623 Corrected a bug in varsTouchedAfter that was related to flowAlgorithm and was causing the odd bug in checkUnusedVar 2008-11-20 15:39:28 +00:00

be6c57ce5b Corrected some of my documentation of flowAlgorithm that has repeatedly confused me ever since I wrote it 2008-11-20 15:39:06 +00:00

e117422c31 Added a couple more tests for checkUnusedVar which has revealed two bugs 
One of these bugs is that array variables are counted as unused when they are used subscripted.  I think that should be solved when we flip back to the listify approach.

The second bug is more interesting, as it is triggered only in a certain arrangement with an IF.  It's either a bug in the flow-graph building or in the varsTouchedAfter code.
