cd36f383c9 Turned off unused variable checking for now -- I think it's bugged 2009-03-25 18:33:23 +00:00
Neil Brown
1c4d44b739 Fixed generation of C types for channels (somewhere, one is being abbreviated with ValAbbrev, so I'll allow it for now) 2009-03-25 18:27:13 +00:00

fd7de709c0 Fixed the counter-example generation so that it works even when inequalities remain after the problem has been solved
Fixes #86.

9b753edde2 Got arrays abbrevs with unknown dimensions in the type to take the type from the RHS 2009-03-25 16:38:40 +00:00

eaa8ece954 Fixed allocation of mobile channel bundles, as apparently a clone is unnecessary 2009-03-24 23:54:13 +00:00

b100b828e1 Fixed the lexer so that it will give an error about pragmas rather than an internal failure 2009-03-24 02:14:51 +00:00

e269efe388 Added some quick hacks to make recursive PROCs work
This is along the lines of the Tock ticket.  cgtest90 (recursive FUNCTIONs) now passes, but cgtest91 (recursive PROCs) doesn't, because it uses barriers.

e08197bbef Added various bits for shared channels, which now means that cgtest86 compiles and passes 2009-03-24 00:08:02 +00:00

fae0d6d6a2 Made intrinsic PROCs take the workspace as a parameter, and turned . to _ in their names (and implemented the RESIZE.MOBILE.ARRAY.1D intrinsic) 2009-03-23 15:46:24 +00:00
Neil Brown

8492dc03d4 Introduced a ShareMode in the AST, and used it in the channel attributes (rather than Bool) 2009-03-22 22:29:39 +00:00

12b3c4cd89 Added a pass (and adjusted the backends) to deal with the move-in move-out semantics of mobiles
Also known as communication semantics, I think.  The pass adds an extra channel parameter per mobile (perhaps in future this could be a single extra channel?) that is used to send back the mobile value, and hacked the backend so that the communications to receive these mobiles are done in the right place (after the processes have been run, but before waiting on the barrier for them to complete).

cgtest83 now compiles, runs and passes without a segfault.
