b2d944974e - first stage of simplifying the type system.
Let's use inline checkers in PType instead of constantly having to do clumsy IsKindOf checks etc. Once complete this also means that the types can be taken out of the class hierarchy, freeing up some common names.

6599e2c425 - moved the VM types into their own file and only include it where really needed. 2017-04-13 01:12:04 +02:00

96631e8808 - make PClass not inherit from PStruct.
Having these two types related can cause problems with detection in the compiler because for some parts they need quite different handling.
Common handling for the fields has been moved into PSymbolTable but overall redundancy was quite minor as both types share surprisingly little functionality.

31223ca180 - remove all symbols that get linked into the symbol table from the garbage collector.
Symbols are very easy to manage once they are in a symbol table and there's lots of them so this reduces the amount of work the GC needs to do quite considerably.
After cleaning out compile-time-only symbols there will still be more than 2000 left, one for each function and one for each member variable of a class or struct.
This means more than 2000 object that won't need to tracked constantly by the garbage collector.

Note that loose fields which do occur during code generation will be GC'd just as before.

f1b3d60b2f - PSymbol does not need to inherit from PTypeBase. This also means that there are no remaining references to any symbol object outside of the symbol tables. 2017-02-08 13:37:13 +01:00

18c532c307 - moved the compiler symbols into their own file.
- removed all pointer declarations to types from the symbols. All types must be placed into the type table which means that they can be considered static.
