a4f0e85c72 Fixed a bug involving abbreviation of arrays of channels into arrays of channel-ends in the C++ backend 
The array for the channel-ends was not being allocated storage, so the array (a pointer to some random location) was being written to and causing a seg-fault

6ff8e3b163 Fixed a bug where records were being recorded with the wrong name type in the occam parser 2009-01-28 22:11:23 +00:00

52459e7557 Turned on usage checking by default 
I think the Tock usage checking is now sufficiently advanced (it only rejects one or two parts of the cgtest at the moment) to turn it on by default
 2009-01-28 17:34:34 +00:00

addcefdab2 Stopped GCC warning about unused variables 
We detect real unused variables from the occam program ourselves, but we don't want GCC warnings for all the unused _sizes variables and so on
 2009-01-27 12:56:32 +00:00

c30db7b11e Added in C headers (dummy bodies) for all the intrinsic functions that I have so far defined in the Intrinsics module 2009-01-25 20:42:57 +00:00

7337978dcf Added many more intrinsics to the list of occam intrinsics 2009-01-23 19:19:36 +00:00
Neil Brown
1410e80fb1 Added support for intrinsic functions with multiple return values 
Previously, such a function was an IntrinsicFunctionCall inside one expression of an ExpressionList, which the type-checker rejected.  I've had to add a new constructor to ExpressionList, and I've quickly hacked together the line in the C backend to make it work -- but it does seem to work.

91f004a197 Realised that with channel-ends for C++CSP, I want to use AltChanin everywhere, not Chanin 2009-01-23 18:10:51 +00:00

fab6850041 Added code to infer the directions of undirected channel formals, where possible 
Fixes #24

I still need to do a little more, however, to pass my more elaborate examples in the test file.

c8a8370636 Remove the comment about needing to add overflow checking 
Fixes #24

In that, it is the last patch in a series that fixed the lack of overflow checking in all the integer operations.

7457d894f8 Tweaked the C and C++ backends to take the replacement for Int from the TypeSizes module rather than calculate it locally 2009-01-23 15:52:28 +00:00
Neil Brown
9145c993ea Fixed the constant folding to use a type for Int based on the compilation target rather than just assuming Int32 
However, it is possible that there will still be a problem if the C and C++ compiler have different int sizes, because the constant folding has to know the type at compile time, and thus we have to arbitrarily choose to use the C version.  In future, we could perhaps swap all Ints for the appropriate substiution (e.g. Int64) at run-time, based on the flags and prior knowledge about C/C++ int sizes
