0a67b804bb Added more intrinsically-defined operators to the list 2009-04-07 16:01:44 +00:00
Neil Brown
f7e114f2fd Overhauled the Types module and ParseOccam to support the new system of operators-as-functions 
The idea behind this is to parse unary/binary operators into function calls with 1/2 operands.  So the AST actually has a FunctionCall with the name "+".  Function names may now be quoted operators, and thus you can also have function declarations with names such as "+".  Resolving is *not* done in the parser for these function names, but rather every "+" is left as "+" (no matter what types it operates on, or what is in scope) by the parser (see later patches to InferTypes instead).

When parsing an occam source file, we automatically insert a bunch of PRAGMA TOCKEXTERNAL that define the default occam operators (e.g. + on INT) as external C functions (which they are!).  The naming scheme for these C functions is standardised, and must be used by functions such as mulExprs (which bases the function on the type of its operands) and the new versions mulExprsInt (which are pegged to INT).

The Types module also has some new functions for dealing with operator-functions.

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.

1e538fc592 Fixed ShowCode to print direction specifiers in the right place after variable names, as it's important now that what we spit out for PROC headers is legitimate occam 2009-04-01 17:08:04 +00:00

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

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.
