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

9913bddb28 Fixed array constructor types that have been lifted to mobile arrays 2009-03-22 21:05:05 +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.

defca6e34d Started simplifying some of the C backend in light of the new changes, and made a few fixes 
The first few cgtests (at least) now pass with the new system in the C backend.

ca207f7291 Quickly implemented the first version of a revamp of the genVariable code in the C backend 
Surprisingly, the generated code seems to be compiled by GCC without warnings.  Array subscripts are currently unimplemented (a star, i.e. equivalent of subscript 0) is used wherever there should be a subscript.

The new mechanism is based on working out the C type of the original variable/abbrev-mode, the C type of the desired variable/abbrev-mode, and works out how many *s or &s to insert to coerce it to the right type.

1343954c2f Added an option to automatically run indent on C/C++ source before running GCC 
This option is very handy when debugging the C/C++ output of Tock when GCC gives a compiler error.
