- fixed: The state index comparison against 0 was broken.
- fixed: Resolving codegen nodes must set the strictness flag per function so that ZSCRIPT and DECORATE are done properly.
- added an 'exact' parameter to FThinkerIterator's Next function. This is mainly for scripting which allows to do a lot more checks natively when running the iterator while looking for one specific class.
This bypasses a declaration in the script in favor of a simpler implementation. In order to work it is always necessary to have an offset table to map the variables to, but doing it fully on the native side only requires adding the type to the declaration.
- fixed: divisions wasted one register for each operation due to a double allocation.
- changed math operations to use less registers. There was a well-intended change to allocate the destination first, but the better approach is to first allocate the operands and free then before allocating the destination register.
- added support for global variables to the code generator - not the compiler, though. For the handful of entries this is needed for it may just as well be done manually. So far FLevelLocals level is the only one being exported.
- fixed: The VM disassembler truncated 64 bit pointers to 15 digits because the output buffer was too small.
- resolve entire FxSequences instead of aborting on the first failed entry. This allows to output all errors at once.
* Revert "Modify CMPJMP to produce more compact code (as far as VC++ is concerned, anyway)"
This reverts commit 6ff973a06b.
This modification did not work and broke the comparisons. Actually this had three problems:
* the asserts checked the wrong instruction
* the mask was not applied to regular comparisons.
* incrementing PC before testing does not work because 'test' references the PC.

Daedalus triggers this with a 0x85 character which in Windows CP 1252 is the ellipsis (...) The converter will assume ISO-8859-1, though, but cannot do anything with these characters because they map to the font being used here.
- These require manual detection and overriding of the scaling factors to
0, because a right shift of (32-0) bits wraps around to 0 and results in
no shift at all rather than leaving the register zeroed out.
- dc_destorg is normally set to the upper-left corner of the view window.
If there is a border, then this won't coincide with the upper-left
corner of the screen, and DCanvas::FillSimplePoly would merrily write off
the end of the screen buffer.
- exported thinker iterator and drop item chain to scripting. Unlike its native counterpart the script-side iterator is wrapped into a DObject to allow proper handling for memory management.
- fixed: The VMFunctionBuilder only distinguished between member and action functions but failed on static ones.
- fixed: FxAssign did not add all needed type casts. Except for purely numeric types it will now wrap the expression in an FxTypeCast. Numeric handling remains unchanged for both performance reasons and not altering semantics for DECORATE.
- exported all internal flags as variables to scripting. They still cannot be used in an actor definition.
- make ATAG_STATE the same as ATAG_GENERIC. Since state pointers exist as actual variables they can take both values which on occasion can trigger some asserts.
- gave PClass a bExported flag, so that scripts cannot see purely internal classes. Especially the types like PInt can cause problems.
Todo: we need readonly references to safely expose the actor defaults. Right now some badly behaving code could overwrite them.
Added restriction of Require/Exclude to ZSDF (namespace = "ZDoom";).
A warning will be printed if a Require/Exclude block is detected in USDF (namespace = "Strife";).
Added two new sub-blocks for Choice blocks: Require and Exclude.
The syntax for both is the same as Cost blocks.
Require defines what item must be present in your inventory in order to show this choice/reply.
Exclude defines what item must not be present in your inventory in order to show this choice/reply.
If any Require/Exclude blocks are defined then this choice/reply will be hidden until all blocks of both types are satisfied.
- fixed: FxMinusSign trashed local variables that were used with negation.
- fixed: FxConditional only handled ints and floats, but not pointers and strings.
- fixed: A 'no states in non-actors' error was triggered, even for classes without any states.
- fixed several occurenced where vectors were treated as floats. NOTE: The entire codegen.cpp file needs to be carefully reviewed for bad use of the REGT_ constants, there's probably more places where using them has broken some type checks.
- fixed: committed test version of zscript.txt instead of changed actor.txt by accident.
Initialization and assignment for strings is working with this commit.
- removed the bogus optional value from the first A_Jump argument. A quick test with an older ZDoom revealed that this was never working - and implementing it would make things a lot more complicated, especially error checking in the code generator.
- fixed: The check for insufficient parameters to a function call was missing.
- removed mulv_kr and divv_kr instructions. The first are redundant and the second are useless. Maybe remove all other vector/const operations as well? They won't get used by the code generator.
- fixed disassembly of vector multiplication and division instructions.
- added initializer syntax for vectors. A vector can be set with vectorvar = (x,y,z); for a 3-dimensional vector and vectorvar = (x, y); for a 2-dimensional one.
- swapped parameters of two-parameter VelToAngle method, so that internal and script version are in line.
- fixed parameter asserts to handle NULL pointers properly.
- 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.
- disabled the assert in PType::GetRegType. This assert blocks any use to check for types that are incompatible with function parameters.
- pass the default parameter constants to the native functions. At the moment this is not used yet.
- use the function defaults to complete argument lists to script functions.
- fixed all default values that got flagged by the expression evaluator as non-constant. Most were state labels and colors which were defaulted to "". The proper value is null for states and 0 for colors.
- also replaced all "" defaults for names with "none".
