1124bb5a44 Use either Alt or TimerAlt as appropriate. 2008-03-15 15:15:21 +00:00

4a68dda2b5 Clean up the generation of wrapper Procs for Pars. 
Procs that are in csParProcs are now generated with the correct calling
convention directly, rather than having a second wrapper function generated
around them.

9c2a6b6656 Handle both addl and subl for stack increases. 
GCC seems to very occasionally generate addl -N rather than subl N.

Also don't allow subl -N any more -- if it's adjusting the stack pointer back
up, that doesn't mean it's going to use any less of the stack...

5156626ab0 Remove the identifyParProcs pass. 
All it did was to make a list of the Procs generated by parsToProcs, so
parsToProcs may as well just do the same job itself.

The reason I'd made it a separate pass originally was that I wanted to
optimise out the wrapper when the child of a Par was already a ProcCall.
That optimisation isn't going to be possible any more with the new CCSP,
since wrappers have to fetch their arguments in a different way from
ordinary Procs.

3996a1379b Update BackendPassesTest to match my last _sizes change. 2008-03-13 10:52:23 +00:00

006559271d Declare size arrays before the corresponding real arrays. 
This is because we sometimes need the size array while initialising the real
array -- for example, if we're initialising a 2D array of channels.

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: ".

f2d3280cee Abstract killing TLP channel handlers out into a function. 2008-03-12 10:47:19 +00:00

8880413128 Use TimerAlt rather than Alt. 
It really ought to pick the right one depending on whether there are any timer
guards.

7eaab68f04 Implement TLP output channels using a CIF helper process. 
Input channels will be similar, but are stubbed out for now.

f8d4efa0e9 Go back to generating Time variables for timers. 
This is for two reasons: first, the C++CSP backend still needs them, and
second, the way I'd done the removal wasn't correct; since you can have arrays
of them, abbreviate them, etc., they need to be stripped out by an earlier
pass so that other passes don't try to operate upon them.

35538cda36 Resolve conflicts. 
This simplifies the formals/actuals stuff enough that most of it can probably
go away (once it's made to work again).
