350057c314 Made sure that non-top-level specs still have forward declarations in the .c file (and not in the .h file) 2009-04-02 15:43:49 +00:00

f69030df34 Changed the names of generated tock files to have ".tock" before the extension 
This helps avoid collisions with pre-existing files, especially .inc files (but also .c and .h)

ea14f568fa Removed genProcName 
Everything that used it has now switched back to genName, as we don't need this occam_ prefix with the new name munging stuff from earlier patches.

ef36c39c38 Stopped the C code generating extern declarations for occam PROCs (it should only do this for C PROCs) 2009-04-01 19:51:43 +00:00

e28bff5a50 Added code to put static before every identifier that is not being exported, to avoid collisions between occam files 2009-04-01 19:50:15 +00:00

7e7a437a3b Switched to using a different kind of pragma for occam externals, and munged the names to avoid collisions 
The separately compiled occam PROCs now use #PRAGMA OCCAMEXTERNAL, which also discards the "= number" thing at the end.  These PROCs then need to be processed differently when adding on the sizes (C externals have one size per dimension, occam externals have the normal array of sizes).

We also now record which processes were originally at the top-level, and keep their original names (i.e. minus the _u43 suffixes) plus an "occam_" prefix to avoid collisions.

8153cfc659 Added code for full compilation mode to include the relevant C files from occam #USE directives, and link to the relevant object files 2009-04-01 18:32:39 +00:00

d457b793c0 Added code that allows any external PROCs not beginning with B or C to be handled as normal 
This shows that my current scheme is a bit of a hack; if an occam programmer starts a normal PROC with B or C, it will be treated funny during separate compilation.  In future I probably need some new form of #PRAGMA to support separate compilation, different from that used to interface with C.

db9b8e9d91 Changed where we generate the .inc file from being in the backend, to being a pass just after type-checking 
We need to generate the externals after we've inferred channel directions, but before we do further work (like adding _sizes parameters and so on).

219bfd9ce1 Modified the C backend so that it will put the forward declarations into a header file and include that 2009-04-01 14:35:47 +00:00

e9730bfe1e Got the C++ backend working again, on the cgtests at least 2009-04-01 15:25:18 +00:00

e91c075bcf Fixed up a lot of the failing tests 
I changed a little bit of the code, but mainly the tests.  Several of the remaining failures are actually real failures, so I need to dig through the rest carefully.  A lot are failing because the C++ backend is broken.

bea4dcfd80 Took out some C garbage, which gets around 200 more tests passing 2009-03-31 18:02:39 +00:00

56e5b8da8e A mega-patch that gets tocktest compiling again 
However, around a quarter of the tests currently fail...

4d2cdc0a9d Altered the backend passes to use all the new VariableSizes mechanisms rather than the old stuff 
This is quite a big patch, as it reworks a large pass.  The three backend passes dealing with sizes stuff have now been merged into one (because the traversal order is important).

Instead of generating sizes arrays by blindly appending "_sizes", we now create nonces and store them in the csArraySizes map in CompState, which is a bit less hacky.

Added to that, we also generate constant-size arrays (e.g. for [8]) -- which are needed in case we pass the array to a PROC that has a flexible dimension -- at the top of the whole program, and use that array for every variable with that size (so if foo and bar have the same size, we use the same sizes array from the top of the program).

a10921d53a Fixed the last few uses of genSizeSuffix in GenerateC to use the new system instead 2009-03-31 09:35:59 +00:00
Neil Brown
f749967af4 Added some cases inside genVariable to handle the VariableSizes item 
For mobile arrays, this uses the ->dimensions member.  For normal arrays, it uses the associated sizes array (by looking it up in CompState).

298ba6465a Removed genSizeSuffix and turned most uses of it into calls to genDynamicDim 2009-03-31 09:29:55 +00:00

b8daebfbc3 Made genDynamicDim a top-level function, and change its implementation to use VariableSizes rather than C-specific stuff 2009-03-31 09:28:45 +00:00

0ca5bb17d7 A collection of nasty hacks to get Tock's replicated PARs working, and to stop memory leaking 
All the changes in this patch should be undone as soon as possible (building the list of workspaces, and how we sort out the enrollment counts -- that should be done by pulling up PAR replicator counts outside the whole PAR), but for now, it works.

dbf0b90601 Fixed array sizes for external procs to have one extra formal per dimension, rather than passing the whole array in a single formal (this is now how it should work!) 2009-03-27 16:28:23 +00:00

1c4d44b739 Fixed generation of C types for channels (somewhere, one is being abbreviated with ValAbbrev, so I'll allow it for now) 2009-03-25 18:27:13 +00:00

eaa8ece954 Fixed allocation of mobile channel bundles, as apparently a clone is unnecessary 2009-03-24 23:54:13 +00:00
Neil Brown
e269efe388 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.
