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.

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.

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.

b17ab7a133 - put PObjectPointer to some use.
- fixed: There was no check for compatible class pointers.

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.

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.

4afe2d4218 - moved OwnedStates and NumOwnedStates out of PClassActor. 2017-04-11 22:44:35 +02:00
Christoph Oelckers
6a3ddaa8fa - moved Restricted/ForbiddenToPlayerClass fully to the script side.
This required some fixes for allowing to read from metadata arrays.

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

e551ef52f8 - removed atag parameter from GetConstantAddress. 2017-04-10 15:39:04 +02:00
Christoph Oelckers
ef77cbd295 - stop using the ATAGs for checking pointer types in asserts.
This is an incredibly costly way to do a debug check as it infests the entire VM design from top to bottom. These tags are basically useless for anything else but validating object pointers being passed to native functions (i.e. mismatches between definition and declaration) and that simply does not justify a feature that costs execution time in non-debug builds and added memory overhead everywhere.
Note that this commit does not remove the tags, it only discontinues their use.

74faacd218 - fixed: FxVMFunctionCall::GetDirectFunction did not perform any checks on the function's self pointer and failed to report a mismatch as an error.
- also fixed two places in the code where the above caused some incorrect definitions not to be detected.

41f2f61b94 - minor VM optimization: Precalculate a function's frame size when compiling it instead of doing it each time it gets called.
This made up ca. 10% of the 'call' instruction's execution time.

19e7d60275 - removed DSBarInfo::Scaled because it tended to disagree with StatusBar->Scaled. 2017-03-29 00:35:35 +02:00

a6bf93c624 - implemented the Heretic status bar. 2017-03-27 21:01:40 +02:00
Christoph Oelckers
a3ee3c287e - major progress on the status bar code: SBARINFO's DrawGraphic has been ported into a generic function of the base statusbar class and put to use for a few items on the Strife status bar.
- decided to ditch the widget system I had started to lay out. As it turns out that would make things far more complicated and slower than they need to be.

31ea33bfc4 - rewrote the condition nodes from SBARINFO in ZScript. This compiles but hasn't been tested yet. 2017-03-23 00:25:26 +01:00
Christoph Oelckers
0721aef218 - fixed: FxAssign used the wrong value type for emitting the store operation.
It used the expression's value type, but needs to use the variable's, which can be different when the assignment is synthesized from a builtin function.

Christoph Oelckers
403c5693a9 - cleaned out a large part of unused methods from VMValue.
- keep string registers which are being used as function parameters allocated until after the function call returns. This is for allowing to pass strings by reference which would avoid some costly constructor/destructor loops in the call instruction.

1e9ef2b1df - started scriptifying the level intermission screen. This compiles but is not active yet.
- allow treatment as one-character string constants as character constants. This became necessary because name constants already use single quotes and are much harder to repurpose due to a higher degree of ambiguity.
- fixed: protected methods in structs were not usable.

Christoph Oelckers
6037ecb6a1 - fixed: Getting the offset to the 'Size' field for static arrays should use a fixed offset, not the size of the defining variable, which, depending on where things are defined, can be different. 2017-03-13 20:27:46 +01:00
Christoph Oelckers
5fd86cf98c - added some syntactic help to the ZScript parser to allow defining the arrays with native structs on the script side instead of having to define them internally. 2017-03-13 12:51:09 +01:00

77bac4f6fa - fixed code generation for min/max when the first operand was a local variable or constant.
The code for constants was not optimal because the first operand of the instructions cannot be constant. This was solved by swapping it with the second choice which will always be non-constant.
The code for local variables did not allocate a new destination register and would overwrite the first parameter's variable.

e2f3a09dd0 - refactored the scope check for VirtualScope calls.
It now uses a dedicated opcode instead of piggybacking on OP_CALL and it passes data that is closer to the VM. Symbols should be avoided at this level.
It also will skip the scope instruction if the code generator detects that both calling function and the self pointer type have the same scope, this assumes that subclasses cannot flip between UI and Play.

0c686c593b - simplify the runtime checks for OP_NEW.
They are not needed for OP_NEW_K which can evaluate the class relations at compile time and for OP_NEW the calling function can also be checked at compile time, passing only the scope value itself.

456ac64723 - implemented version checks for compile-time type determination and for class inheritance.
