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

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.

b08d48bd43 Added more remainder tests, and fixed our implementation of remainder to pass the tests 2009-01-22 12:58:53 +00:00

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

0627ff2b4f Changed the Rain TLP interface to use lists for output streams as I'd originally intended 2008-05-21 00:20:29 +00:00

0b1708c241 Added the equality operator for tockList in the C++ support code 2008-05-21 00:20:11 +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

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
Neil Brown
986a4acb2b Added support for a StreamReader (to support the input channel from stdin) to the C++CSP backend 2008-03-24 23:46:05 +00:00
Neil Brown
e8adfb51fa Moved the code for setting up the terminal into tock_support.h so that C++CSP can use it too 2008-03-24 23:45:31 +00:00
Neil Brown
fc4cac736b Added the helper functions for adding and subtracting Times in C++CSP 2008-03-23 13:29:22 +00:00
Neil Brown
5abb775ae4 Added the time-related intrinsic functions for Rain to the C++ backend 2008-03-23 12:39:16 +00:00
Neil Brown
887a3ba98d Added helper functions for int8_t to tock_support.h (Rain needs these) 2008-03-23 12:18:18 +00:00
Neil Brown
bc7e682119 Added a Concat operator for lists, and added support for it (and list assignment) to the backends 2008-03-21 19:20:15 +00:00
Neil Brown
839d92546b Altered the backends to support lists and foreach loops over lists (at least in the C++ part) 2008-03-19 17:20:52 +00:00

b814e81bec Do away with the killval hack. 
This now uses the same approach to detect a kill as libkrocif.

d7333e4479 Implement FLUSH in the output handlers. 2008-03-12 14:48:27 +00:00

88af6a29d2 Abstract CCSP setup into a function, and set up terminal properly. 
If stdin is in use, it'll now be put into non-canonical mode. This is almost
the same as libkrocif's behaviour, except I've set VTIME to 0, since I don't
think there's a good reason to have a terminal read complete if no characters
are available.

This also sets CCSP's branding to "Tock", so error messages now start "Tock: ".

ac532be667 Implement stdin input handler. 
This uses a slight hack to figure out when a killable BSC has actually been
killed (which I think should probably be a CCSP feature anyway).

f2d3280cee Abstract killing TLP channel handlers out into a function. 2008-03-12 10:47:19 +00:00
Adam Sampson
7eaab68f04 Implement TLP output channels using a CIF helper process. 
Input channels will be similar, but are stubbed out for now.

0265063250 Re-added the index checking for array slices in the backend 2008-03-09 16:19:01 +00:00

5c43172e46 Added an annotation to array subscripts to indicate whether they should have a run-time check added or not 2008-03-09 14:30:19 +00:00
Neil Brown
5197435b2c Removed a lot of old comments and support code relating to the way arrays used to be handled in the C++ backend 2008-03-08 13:52:50 +00:00

9ad4552232 Moved the error message for occam_stop into the StopException for C++, rather than printing it directly 2008-03-05 17:12:01 +00:00
Adam Sampson
50967cba95 Split the common C99/C++ support code out into a separate header. 
Or, rather, add a new CIF-specific header, so tock_support.h is now the common
code and each of the backends has its own. This means some of the conditional
stuff can go away.
 2008-03-05 16:54:29 +00:00

bb419d28b7 Move the headers into their own directory, and install them. 
This should make it possible to use Tock from outside its own source directory.
