948ef62fcd - use the function defaults from the script instead of explicitly setting them again in the code. This is a needless cause of potential errors and since the values are readily available now it's better to use them in the functions.
- fixed: ZCCCompiler did not process array access nodes.
- fixed: Function argument names were not placed in the destination list by the compiler.
- scriptified several trivial functions from p_actionfunctions.cpp.

2da52cedc9 - restrict 8 and 16 bit integer types to struct and class members - and I am not really sure if they should even be allowed there, aside from legacy readonly properties. For 32 bit floats the same would hold, but those are already mapped to 64 bit doubles silently.
ZDoom only uses these types in a very few isolated places, and even those can be removed without problems, so it's very doubtful that having support for these types is of any benefit - on the other hand, having them will most likely introduce more code than is saved in the data by using them...

847b8c45ef - Changed ZCCCompiler::Simplify to allow running in constant and non-constant mode. The difference is that non-constant mode does not attempt to simplify function name expressions because these cannot be processed without destroying them, if some identifier in there is not referencing a symbol, which is quite common. 2016-10-16 01:33:36 +02:00

32a3f57a54 - more preparations to compile functions:
* Allow PFunction to work without a VMFunction being attached.
 * The Variant for a function must store the prototype itself instead of relying on the VMFunction it points to. Otherwise it would not be possible to reference a prototype during compilation of the function because it does not exist yet.
 * Give the variant a list of the function's argument's names, because these are also needed to compile the function.
 * create an anonymous function symbol when the function gets registered to the builder. At this point we have all the needed information to set it up correctly, but later this is no longer the case. This is the most convenient info to have here because it contains everything that's needed to compile the function in the proper context, so it has to be present when starting compilation.
 * added some preparations to implement special handling for weapons and custom inventory items, which can run action functions in another actor's context. This part is not active yet but the basics are present in SetImplicitArgs.

2cb5839c11 - count errors in the parser and abort afterward if there were some.
- use FScriptPosition's error counter throughout the compiler so that there is only one counter for everything, not two.

Parts of the compiler use FScriptPosition, so this is easier to handle than having a separate counter in the compiler class. It also avoids having to pass the compiler object to any function where an error may be output. The TreeNodes contain sufficient data to be converted to an FScriptPosition and using that for error message formatting.

7de683f9f5 - converted a few more DECORATE files.
- started with the AST converter. So far it only deals with direct function calls with simple constants as parameters.
- added an error condition for the defaults block to get rid of some asserts.

b1a83bfd26 - started with cleanup and separation of DECORATE code.
* everything related to scripting is now placed in a subdirectory 'scripting', which itself is separated into DECORATE, ZSCRIPT, the VM and code generation.
 * a few items have been moved to different headers so that the DECORATE parser definitions can mostly be kept local. The only exception at the moment is the flags interface on which 3 source files depend.
