Fixed allocation of mobile channel bundles, as apparently a clone is unnecessary

Fixed the lexer so that it will give an error about pragmas rather than an internal failure

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.

Realised that allocating mobile arrays as arrays of bytes screws up the resize intrinsic, and gave it a helping hand

Realised that mobile arrays should be allocated after all, unless they are missing a dimension

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

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.

Fixed one of the occam passes so that it no longer enforces that mobile array dimensions are statically known
