2a321d7910 Added a NameExternal item to NameSource, to stop using NamePredefined for externals 2009-04-04 14:56:00 +00:00

cfcf50297f Added the new tock include directory to the standard search path 2009-04-04 12:29:53 +00:00

45db9cdd27 Realised that my bits and bytes per word were somewhat mixed up 2009-04-03 20:19:48 +00:00
Neil Brown
c0ead7b5a8 Added some of the standard occam defines, such as TARGET.BITS.PER.WORD 
For the moment, TARGET.HAS.FPU is left out, because a lot of occam libraries seem to do ASM if it's defined, and we can't handle ASM

5f124636fb Fixed the name munged to be stable for #USE directives, but use the old name counter for #INCLUDE directives 
This is necessary because occam files often #INCLUDE something multiple times (e.g. cgtests) and want different names, but this is not the case for #USE.

427938039c Implemented a search path for Tock (for #INCLUDE and #USE directives) 2009-04-03 16:51:00 +00:00

d6ad0ba202 Made the name of record-copying PROCs different for each file that generates them, to avoid clashes at link time 2009-04-03 10:25:55 +00:00
Neil Brown
dbc1b461a4 Made makeNonce use the munged meta-tag, to stop wrapper PROCs from different files having name clashes at link-time 2009-04-02 20:02:11 +00:00
Neil Brown
460c3e287f Changed names to be uniquified based on their source position, and fixed the source position for things in pragmas 
The second part of the patch is essential, given the first.  Otherwise names in different pragmas in the same file can overlap -- this already happened in oak!

ca818d423c Made the munging of the names include the file name, to help with separate compilation 
This will allow (along with a few patches in a minute) different occam files to declare the same PROC, and have it resolved correctly based on the order of their declaration, just like if it was all in one file.

a307e39d47 Added a Read instance for Meta (taken from my benchmarks for the ICFP paper) 2009-04-02 15:07:17 +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.

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).

abce001bab Added a command line option to indicate that there is no main PROC 2009-04-01 15:29:22 +00:00
Neil Brown
b830b27066 Added a couple more settings to CompState to set the locations of the (C and occam) header files (but not made them available via the command-line, just yet) 2009-04-01 14:34:13 +00:00
Neil Brown
2edf5cc43d Fixed constant folding to resolve any user types involved 
Due to awkward module dependencies, some functions had to be moved around to accommodate this change.  Two from Types have gone to EvalLiterals, and two to CompState.  Everything still compiles just as before though.

dbf886996a Removed various bits of old code relating to the old sizes mechanism 2009-03-31 10:50:04 +00:00
Neil Brown
904d19a6a5 Added a new VariableSizes constructor to Variable that will supplant SizeVariable and AllSizesVariable 2009-03-30 15:28:38 +00:00
Neil Brown
b86ffbbf3b Added two new items to CompState, which will help to replace the _sizes suffix 2009-03-30 15:13:56 +00:00
Neil Brown
6e66cf7521 Added a command-line option to change how much stack the unknown functions are given 2009-03-26 22:49:38 +00:00

eb99480484 Finished off the support for external C functions 2009-03-26 22:37:28 +00:00

95d7144c7b Added the ability to specify linker flags separately from C compilation flags 2009-03-26 22:36:13 +00:00
Neil Brown
09093cff12 Added the ability to print out HTML-highlighted lexed occam 
This falls a bit outside the compiler's remit, but it will be the same code to print out the lexed occam without highlighting, which I plan to use for doing libraries with Tock in a bit.

633a3dbbc5 Quickly added a command line option to allow you to specify flags to pass to the C/C++ compiler 2009-03-25 22:35:49 +00:00
Neil Brown
45b22472c3 Changed the rest of tock to reflect the changes to the Is constructor 2009-03-24 23:57:24 +00:00
Neil Brown
53f7378988 Merged IsClaimed, IsChannelArray and IsExpr into Is, which now takes an Actual 2009-03-24 23:56:53 +00:00

5ffea3f78e Added a lex mode to Tock that shows how a program was lexed 2009-03-24 18:18:55 +00:00
Neil Brown
19e0fb0573 Added an AllocChannelBundle constructor in ExpressionList for assignments that allocate the two ends of a mobile channel bundle 2009-03-23 18:58:50 +00:00
Neil Brown
41805aaacf Changed the ChanEnd constructor to only keep information about its shared-ness, not about the whole channel 2009-03-23 18:40:28 +00:00
Neil Brown
1edabee2e7 Changed the AST claim element to be an abbreviation rather than a process 2009-03-23 15:52:19 +00:00
Neil Brown
5f9d0c6429 Added various keywords, AST elements and parser bits related to channel bundles, claim blocks and shared channels 2009-03-22 22:49:49 +00:00
Neil Brown
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
Neil Brown
03f1b2d115 Added a few more mobile things (DEFINED keyword, an intrinsic) 2009-03-20 20:53:51 +00:00
Neil Brown
1c0f4d17ca Changed the RecordType item to support multiple attributes (including mobility) 2009-03-20 15:17:15 +00:00
Neil Brown
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.

65550b705e Added an AllSizesVariable item to the AST so that the backend inserts the right code for mobiles and non-mobiles 2009-03-20 11:31:14 +00:00
Neil Brown
65875f523f Added mobile cloning rather than using dereferencing to copy mobiles 2009-03-19 16:47:31 +00:00
Neil Brown
b970b9df33 Added command line options for occam 2 mobility, and turned it off by default 2009-03-19 11:38:48 +00:00
Neil Brown
823592bd1d Added some passes to mobilise non-mobile arrays 2009-02-27 17:12:08 +00:00
Neil Brown
81959bd76b Added quick preliminary support for the PERMITALIASES pragma 2009-02-10 01:01:23 +00:00
Neil Brown
41cca68e4e Simplified the Rain parser by reintroducing a RangeLiteral item that will get replaced by an early pass 2009-02-03 12:24:10 +00:00
Neil Brown
957699313f Combined ArrayLiteral and ListLiteral into ArrayListLiteral, and dispensed with ArrayConstr in favour of having array literals as Structured Expression that can contain replicators 2009-02-01 21:50:39 +00:00

8a28d765e7 Implemented recursive procs 
This works fine in the C++ backend, not tested with the C backend yet
 2009-01-29 00:43:24 +00:00
Neil Brown
7722e95dfd Added support for recursive functions (not procs, yet) 
At the moment, the information is only needed in the parser, which must define recursive names before parsing the body of the function.  But in future, we should keep the information when the function becomes a proc, and then the C/C++ backends may need to use it (for example, when calculating stack space usage)
 2009-01-29 00:27:11 +00:00
Neil Brown
a68c871329 Added an expression to represent a STEP count to the For replicator constructor in the AST 2009-01-28 23:42:31 +00:00
Neil Brown
52459e7557 Turned on usage checking by default 
I think the Tock usage checking is now sufficiently advanced (it only rejects one or two parts of the cgtest at the moment) to turn it on by default
 2009-01-28 17:34:34 +00:00
Neil Brown
1410e80fb1 Added support for intrinsic functions with multiple return values 
Previously, such a function was an IntrinsicFunctionCall inside one expression of an ExpressionList, which the type-checker rejected.  I've had to add a new constructor to ExpressionList, and I've quickly hacked together the line in the C backend to make it work -- but it does seem to work.

541f7c1421 Turned the Chan type into a Chan type for full channels and a ChanEnd type for the directed ends 
This is the first patch in the series of many that implement this change throughout Tock.

Fixes #70.

f612b99a49 Added a map of name attributes (ready for things like PRAGMA SHARED) to the CompState 
This should possibly (and could in future) be combined into NameDef and the main csNames map

0a98db5295 Changed pshow on CompState (which caused errors) to plain show, by adding a Show instance to CompState 2009-01-15 20:59:37 +00:00
