def5e1d61b Added proper handling for default parameter values of virtual overrides 
Due to how the VM handles default parameters, these must always be identical to the parent to prevent undefined behavior.
So now, if such parameters are encountered, the compiler will either abort (for script version >= 3.3) or print a warning (for older versions.)
Any defaults being specified for older versions will be ignored, though, and the defaults of the parent function be copied to the override.

bcc8972356 - fixed: A preincrement of a local variable generated wrong code if passed as a function parameter. 
Due to the special nature of this expression the code generator got stuck in 'address' mode and passed the address of the variable instead of its value.

425f1408f7 - fixed skip_super application fro ZScript. 
The order of processing is different here so when the property gets parsed there are no states to delete.
To fix this the property just flags the class and lets the ZScript state compiler deal with this as needed.

74357ced0c Fixed read of potentially junk values in ZScript parser 
The following ill-formed ZScript code might crash targets with sizeof(int) != sizeof(void*) like 64-bit Intel

b4fa95ab15 - handle state label resolution in a non-actor cpntext more gracefully. 
Note that this is merely a hotfix. Properly handling this to allow universal use of state scopes will require more work in cases where a scoped state is being accessed through a non-self pointer.

7983f6ea4f - fixed incorrect return variable. 2017-04-14 15:23:18 +02:00
Christoph Oelckers
cd180d29c7 - block direct use of 'new' for DObjects. 
This is to ensure that the Class pointer can be set right on creation. ZDoom had always depended on handling this lazily which poses some problems for the VM.
So now there is a variadic Create<classtype> function taking care of that, but to ensure that it gets used, direct access to the new operator has been blocked.

This also neccessitated making DArgs a regular object because they get created before the type system is up. Since the few uses of DArgs are easily controllable this wasn't a big issue.

- did a bit of optimization on the bots' decision making whether to pick up a health item or not.

Christoph Oelckers
2d098e99fb - fixed: WP_NOCHANGE had different values in native and script code, resulting in problems with weapon selection. 
This now explicitly allocates a single object it can safely point to instead of trying to hack around it.
 2017-04-13 18:59:45 +02:00
Christoph Oelckers
98dab9c4b9 - took PTypeBase and all its subclasses out of the DObject hierarchy. 
- moved scope flag to a new variable that is specific to PType instead of hijacking the ObjectFlags for this.
 2017-04-13 17:47:17 +02:00
Christoph Oelckers
988fe8d735 - removed all RTTI from the type table. 
Using names is just as good as using types so now this is what's done.

Christoph Oelckers
aeb455d705 - removed all RTTI checks for the types. 2017-04-13 15:38:06 +02:00
Christoph Oelckers
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.

85d8244d03 - fixed: With the reorganization of the class data the setup of actor replacements must be delayed until after InitializeDefaults has been called. 2017-04-13 02:18:06 +02:00
Christoph Oelckers
6599e2c425 - moved the VM types into their own file and only include it where really needed. 2017-04-13 01:12:04 +02:00
Christoph Oelckers
fc9e304189 - separated class descriptors from VM types. 
Combining these two groups of data has been the cause of many hard to detect errors because it allowed liberal casting between types that are used for completely different things.

afd6743965 - moved AddNativeField to PSymbolTable, too. 2017-04-12 18:29:58 +02:00

Christoph Oelckers
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.

0d7b7d6ab1 - merged PStruct and PNativeStruct. 
There were exactly 4 places in the code that checked for the difference, this is better done with a flag.
 2017-04-12 15:12:41 +02:00
Christoph Oelckers
6308251084 - added a FindSymbol wrapper to PClass so that other code does not need to access the symbol table directly. 
- added an isActor utility function to codegen.cpp to simplify a few constructs.
 2017-04-12 13:08:41 +02:00
Christoph Oelckers

Christoph Oelckers
80801d11b1 - removed some redundant static_casts. 2017-04-12 10:29:04 +02:00
Christoph Oelckers
9c9b2ccf6d - replaced more dyn_casts and checks for RUNTIME_CLASS(PClassActor) 
It is preferable to use IsDescendantOf wherever possible if we ever want to be able to separate PClass from PType.
 2017-04-12 10:20:58 +02:00
Christoph Oelckers
5350721ec5 - removed PClass::DeriveData because it is no longer needed. 
- fixed: IsVisibleToPlayer and optimized it a bit more.
- moved SourceLumpName to PClass, so that it can also be used for non-actors (there's a lot of non-Actor classes already.)
- separated the serializer for PClassPointer from PPointer. Even though not doable, a pointer to a class type is something entirely different than a class pointer with a restriction so each should handle its own case.
 2017-04-12 09:55:27 +02:00
Christoph Oelckers
e4d2380775 - moved all remaining fields from PClassActor to FActorInfo. 
- added a few access functions for FActorInfo variables.

With PClassActor now empty the class descriptors can finally be converted back to static data outside the class hierarchy, like they were before the scripting merge, and untangle the game data from VM internals.
 2017-04-12 00:07:41 +02:00
Christoph Oelckers
854053a14f - use TArrays instead of TMaps to store damage factors and pain chances. 
For these fields maps have no advantage. Linearly searching a small array with up to 10 entries is nearly always faster than generating a hash for finding the entry in the map.
 2017-04-11 23:29:37 +02:00
Christoph Oelckers
4afe2d4218 - moved OwnedStates and NumOwnedStates out of PClassActor. 2017-04-11 22:44:35 +02:00
Christoph Oelckers
05240ccbe5 - fixed redundant reallocation of constructable meta fields. 
- some optimization of access to OwnedStates in old DECORATE.
- consolidate all places that print a state name into a subfunction.
- allocate states from the ClassDataAllocator memory arena. States do not need to be freed separately from the rest of the static class data.
 2017-04-11 21:48:41 +02:00
Christoph Oelckers
311ce2362a - started moving stuff out of PClassActor into meta data. 
This reinstates the old FActorInfo as part of the meta data a class can have so that the class descriptor itself can be freed from any data not directly relevant for managing the class's type information.
 2017-04-11 19:37:56 +02:00
Christoph Oelckers
6a3ddaa8fa - moved Restricted/ForbiddenToPlayerClass fully to the script side. 
This required some fixes for allowing to read from metadata arrays.

Christoph Oelckers
7a6e70e777 - reenabled the part of OP_THROW that throws a VMAbortException. This part is still needed for a runtime variable access check. 2017-04-11 00:11:36 +02:00

 2017-04-10 22:18:43 +03:00
Christoph Oelckers
040c70714c - commented out the exception handling opcodes in the VM. 
They are currently not used and not planned to be used - and they are rather costly by increasing stack size per call quite significantly.
