e457d82f0c Changed FUNCTIONs and PROCs to have optional bodies, and put all the externals into the AST (without bodies) 
This may seem like an odd change, but it simplifies the logic a lot.  I kept having problems with passes not operating on externals (e.g. functions-to-procs, adding array sizes, constant folding in array dimensions) and adding a special case every time to also process the externals was getting silly.

Putting the externals in the AST therefore made sense, but I didn't want to just add dummy bodies as this would cause them to throw up errors (e.g. in the type-checking for functions).  So I turned the bodies into a Maybe type, and that has worked out well.

I also stopped storing the formals in csExternals (since they are now in csNames, and the tree), which streamlined that nicely, and stopped me having to keep them up to date.

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

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.

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

2941cbd049 Fixed a problem with record abbreviations being pulled all the way up to the top (which C doesn't like) 2009-03-31 16:50:42 +00:00

9f5b685c02 Corrected a nasty problem with pulling up free names into arguments 
The problem was that the free name could involved in an array dimension (and hence a type) of something in the PROC.  When the name was then replaced in the type, CompState was not updated to have the new type, and instead kept the old type (potentially) all the way through to the backend, where it might be used for checking the bounds of an array index (against the old name taken from CompState, not the replaced name).

152f5fc252 Changed the abbreviation checking so that it doesn't check nonce names 
When we pull up names (which happens before abbreviation checking), we create a lot of nonces with greater scope than the original variables.  When we go to abbreviation check this, we therefore set off lots of false alarms about originally safe code.  So to fix this, the easiest method seems to be turning off checking on all the names introduced by the compiler.
