bf365ee41a Fixed the pass that turns array constructors into replicated loops so that it handles nested array constructors and inner-procthens properly 
cgtest80 now compiles and passes

4b3090b66a Fixed the fixConstructorTypes pass to work properly and put it back into the pass list (having removed it earlier today) 2009-02-02 18:27:04 +00:00

1cde2bd959 Added a few useful error messages in the C backend 2009-02-02 18:26:12 +00:00

96934c871d Changed the transformation of array constructors so that it also pulls out all the specs that were pulled up to be just inside them 2009-02-02 17:36:14 +00:00
Neil Brown
ebf8ae2d83 Added a pull up context just inside the replicators for array constructors 2009-02-02 17:35:46 +00:00

51acf8abb5 Made sure to change the abbreviation for VAL array things that are now being assigned to via a loop as initialisation 2009-02-02 17:34:44 +00:00

88d6136dcf Stopped the expansion of inner array literals into subscripted elements 
This expansion was causing a big blow-up in the code, as things like:

VAL [2][1]INT as IS [[0,1]]

were getting transformed into:

VAL [2]INT n0 IS [0,1]:
VAL [2]INT n1 IS [0,1]:
VAL [2]INT n2 IS [n0[0], n1[1]]:
VAL [2][1]INT as IS [n2]:

Or something similar -- the inner arrays were pulled up into multiple definitions that were then subscripted, because the first pull-up did this:

VAL [2]INT n2 IS [[0,1][0], [0,1][1]]:

and then the inner arrays got pulled up again, separately.  The change hasn't immediately broken anything, but I haven't fully tested it yet

40b9a8b76b Fixed the generated PROCs for copying records not having their definition recorded 2009-02-02 17:23:28 +00:00
Neil Brown
460ee36247 Fixed the pulling up of array constructors into initialisers 
Previously, this was only pulling up constructors that contained single elements, and not constructors that contained multiple elements

1591940996 Removed the fixConstructorTypes pass for now 
This pass was responsible for screwing up the types of all arrays after type inference, and the compiler seems to work fine without it

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

10e6b4ce02 Updated all the tests to work with the new recursive functions 2009-01-29 00:34:12 +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)

a4f0e85c72 Fixed a bug involving abbreviation of arrays of channels into arrays of channel-ends in the C++ backend 
The array for the channel-ends was not being allocated storage, so the array (a pointer to some random location) was being written to and causing a seg-fault
 2009-01-28 23:16:31 +00:00

6ff8e3b163 Fixed a bug where records were being recorded with the wrong name type in the occam parser 2009-01-28 22:11:23 +00:00

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

We detect real unused variables from the occam program ourselves, but we don't want GCC warnings for all the unused _sizes variables and so on
