91092c17ff Added some missing static specifiers to some occam support functions 2009-04-01 18:59:10 +00:00
Neil Brown
e9730bfe1e Got the C++ backend working again, on the cgtests at least 2009-04-01 15:25:18 +00:00

f0a64cb33f Added some Tock support functions for allocating and freeing workspaces 
It turns out that we weren't freeing workspaces, and neither was CCSP, and hence in long-running programs we were leaking memory at a crazy rate.  This fix works, but really this stuff should be in CCSP (Currently, it doesn't seem to have a ProcFree function...)

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

10b4cd7cfc Realised that allocating mobile arrays as arrays of bytes screws up the resize intrinsic, and gave it a helping hand 2009-03-23 21:28:28 +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

062b47bad9 Made some intrinsics stop when they are supposed to (and tested it from rangetest) and implemented a couple more 2009-01-25 22:06:30 +00:00
Neil Brown
588d24bfea Fixed a mistake with a missing type in a header 2009-01-25 22:06:01 +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
Neil Brown
0189ba3793 Began implementing the occam intrinsics (some of them, at least) in the C support header 2009-01-23 19:20:26 +00:00

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.

084fcad1fe Changed multiply back to the very simplest implementation 2009-01-23 13:36:09 +00:00
Neil Brown
ecf840fe9f Had a go at implementing checked-multiply differently, but the results worked out slower 2009-01-23 12:44:37 +00:00
Neil Brown
72a8824940 Had a go at implementing multiply overflow checking (with a single division, and pre-checks) 
I also added an occam testcase to help time the different between * and TIMES.  But gcc optimises out the loop with TIMES under -O2, and with -O0 there is a factor of four difference.

Neil Brown
c79a1ca94c Added a missing header include in tock_support.h that the newer GCC complains about 2008-11-23 19:44:37 +00:00

8625859773 Flush output when the C backend exits. 
This makes "someprog | cat" work -- previously the output never got written.
The C++ support code already does this.

f445ccbdc9 Fix C style. 
The Tock support headers (at least the C side) follow the KRoC C standards,
which are essentially K&R with spaces before function arg lists.
 2008-04-08 15:08:25 +00:00
Neil Brown
0eadbd0b11 Added support for occam's flush (sending 255) and moved some of the unreachable flush commands in the C++ support headers 2008-03-25 11:37:02 +00:00
