c2b37aeeea - fixed a conversion warning with the pointer-type AActor fields.
- added master and tracer to the list of exported variables.
- fixed: 'none' as class type must map to the real null pointer so that it won't get rejected by the stricter type checks.
- added handling for member function calls to zcc_compile.cpp.
- fixed: FxMemberFunctionCall may not delete the self expression if it gets passed on to the actual function call.

371712c53a - turned everything I could into non-action functions.
- fixed emission of the self pointer in FxVMFunctionCall. I did not realize that the self expression only sets up a register for the value, not pushing it onto the stack.

32ac1a8ad7 - moved the special weapon functions from Inventory to StateProvider.
This will restrict them to the only classes that may use them: Weapon and CustomInventory.
Note: Should a mod surface which uses them improperly the better solution would be a warning message and NULLing the bogus code pointer instead of leaving them in Inventory.

d714670acc - allow calling non-action functions directly from a state.
Ironically this only requires a very minor change in the calling code and an added member for the VMFunction to tell that code how many parameters to pass.
This change will allow to turn the vast majority of action functions into regular members, the only ones that still need to be an action function are the few that actually use the pointers.

d6047ae651 - added the required code genration nodes for member function calls.
This is not testable right now because finally the action function mess has come full circle. The current setup makes it impossible to call action functions from non-action functions because the needed info is local to the functions.
Long avoided, this needs to be refactored now so that the different semantics for action functions are no longer needed.

853e49a077 - fixed: R_InitSkyMap must check for the null texture which cannot be used as a sky because it has no bitmap and will cause an access violation in the sky cap color calculation. 2016-10-22 09:58:56 +02:00

43aec68559 - implemented ~== operator.
Turned out this was really simple because the functionality was already there.

5c596d3797 Change VM to increment PC after each instruction rather than before
- VC++ generated horribly stupid code for x64 when incrementing pc at the
  beginning of each instruction by storing hundreds of copies of it for
  every opcode executed. Incrementing pc at the end avoids this madness.
- It is possible I messed something up with this change. Hopefully not.

1e11042de0 - changed VM_EPSILON from 1/1024 to 1/65536 so that the ~== operator can actually be used.
1/1024 is far too coarse for ZDoom's purposes, this needs to be at least fixed point precision.

4b41e735f1 - added null pointer.
- fixed: FxMemberIdentifier checked for ClassPointers instead of object pointers to resolve the left hand side of the expression.
- allow comparison of pointers.

21b690a3c7 Fixed: Player.ViewBob should be multiplying the bobbing height in P_CalcHeight, not the velocity of the bobbing.
This mimics the act of the user altering their movebob CVar to compensate for non-standard player movement speeds.

3e995d7aac - changed assignment operators to be expressions, like they are in C and DECORATE.
This also means that for now Lua-style multi-assignments are disabled, those should be easy to enable by making some changes to the assignment_statement grammar so that it doesn't recognize single assignments, but for now this is low priority because it adds a significant amount of complexity to do this right with functions that have multiple return values.

1450c3dffb - tested and fixed the regular assignment statement for both local and member variables.
The generated object code can definitely use an optimization pass but that's something left for later when more things are working. Right now it creates one opcode more than necessary for all member accesses (instead of using the offset in the store command it calculates an actual address of the variable in another address register) and can create one too many for non-constant expressions being assigned to local variables (a move between two registers because the emitted expression on the right hand side does not know that it can emit to the actual variable's register.)

9f99ca4788 - process most of the remaining statement types.

24394dfc92 - tested and fixed FxLocalVariableDeclaration.
- create proper variable data from the function prototype instead of assuming that there's just 3 pointers.
- added a printable name to VMScriptFunction for error output during gameplay in case something goes wrong.

ffc38d422e - split up FxCompoundStatement into the old FxSequence and a new subclass. FxSequence is just a sequence of expressions, while FxCompoundStatement is the one that actually implements handling of local variables. The split was done so that ZCCCompiler::ConvertNode can return multiple statements as one object and for that FxCompoundStatement is not suitable.
- added conversion of local variable declarations. This is still untested

2d85efce2a - added processing of compound statements to the compiler. This means that anonymous functions without control statements are generating code now.

458c68775f - fixed handling of loop statements.
All break and continue statements were collected in one list, and each loop statement taking hold of that entire list, including the breaks and continues from previous outer loops.
Changed it so that loop statements contain the jump addresses themselves and set a pointer in FCompileContext, so that the jump point can be set directly in the loop statement - and an error printed if there is none in the resolving stage, not the emitting one.
Consolidated the identical backpatching code of the three loop statement nodes into a subfunction.

bef71f29e2 - make generation of the AST dump a command line parameter instead of having it depend on running a debug build.
- disable generation of the parser's trace file in debug builds.

This increases parsing time by a factor of 15 and is only needed when debugging a problem in the grammar.
