cfaa3e3fa9 - changed action function interface so that callers can be identified directly, instead of guessing it from looking at the parameters.
With arbitrary PSP layers the old method was no longer safe because the layer ID was not available in the action function.

05843d3b13 Use "%#g" when disassembly floating point constants
- With "%g", there would be no decimal point if the number had no
  fractional part, making the output indistinguishable from integers.

e83bc53678 Add atan2, which was conspicuously absent, to the VM
- DECORATE now has atan2(y,x) and VectorAngle(x,y) functions. They are
  identical except for the order of their parameters. The returned angle
  is in degrees (not radians).

a3b687bc4e - renamed PARAM_DANGLE macros to PARAM_ANGLE, now that the old angle_t type is no longer used in the VM interface. 2016-03-25 13:23:07 +01:00
Christoph Oelckers
21340c6eba - floatified the rest of thingdef_codeptr.cpp and got rid of the remaining fixed_t and angle_t parameters in VM-accessed function. The VM should now be free of those types completely. 2016-03-25 12:57:22 +01:00

aaae9f2e05 Store known but uncompiled nodes in the symbol table
- Don't bother keeping track of uncompiled nodes in a special table. Use
  the regular symbol table instead. This should in the future make
  compiling nodes referenced deeper than (and before) their definitions
  fairly straightforward.
- Also, break up the compiler's Message() function into Warn() and Error()
  and get rid of zcc_errors.h. I can't really see having a set of error
  numbers being useful.

f332a098cd - reworked calls to P_SpawnPlayerMissile, P_AimLineAttack and P_LineAttack to use floating point angles. 2016-03-18 00:43:05 +01:00
Christoph Oelckers
671291227e - first stage of converting actor angles to float complete
Patched up everything so that it compiles without errors again. This only addresses code related to some compile error. A large portion of the angle code still uses angle_t and converts back and forth.

4a295dfa3d Accept constant definitions in structs.

  be gained by not accepting constant definitions directly.

964ff46063 Add new state options to parser and actually enable them
- Added new state options that DECORATE got to the lemon parser.
- Enable token generation for state options. They were previously not
  generated, so the grammar treated them as function calls instead.

70c663b253 Revert "Add PARAM_STATE_NOT_NULL for the A_Jump* functions"
- This reverts commit cab39973df.
  I was wrong. DoJump never allowed jumping to NULL states.

cab39973df Add PARAM_STATE_NOT_NULL for the A_Jump* functions
- Now that state jumps are handled by returning a state, we still need a
  way for them to jump to a NULL state. If the parameter processed by this
  macro turns out to be NULL, Actor's 'Null' state will be substituted
  instead, since that's something that can be jumped to.

b2ccd0bd28 Use action function return value to make state jumps happen
- The A_Jump family of action functions now return the state to jump
  to (NULL if no jump is to be taken) instead of jumping directly.
  It is the caller's responsibility to handle the jump. This will
  make it possible to use their results in if statements and
  do something other than jump.
- DECORATE return statements can now return the result of a function
  (but not any random expression--it must be a function call). To
  make a jump happen from inside a multi-action block, you must
  return the value of an A_Jump function. e.g.:
    { return A_Jump(128, "SomeState"); }
- The VMFunction class now contains its prototype instead of storing
  it at a higher level in PFunction. This is so that
  FState::CallAction can easily tell if a function returns a state.
- Removed the FxTailable class because with explicit return
  statements, it's not useful anymore.

6d0ef7a9da - added conversion macros to convert floating point angles to angle_t, using xs_Float.h, and replaced all occurences in the code with them (let's hope I found everything.)
Converting a floating point value that is out of range for a signed integer will result in 0x80000000 with SSE math, which is used exclusively for this purpose on modern Visual C++ compilers, so this cannot be used anywhere.
On ARM there's problems with float to unsigned int conversions.

xs_Float does not depend on these

4c17bd65a4 - parameters for FRandomPick should not be added up.

5d2cbf4ecb Improve disassembly of branch instructions
- I kept getting confused trying to read these instructions, so now their
  disassembly looks more MIPS-like:
  * All mnemonics have had 'b' prepended to them for "branch".
  * The CMP_CHECK bit alters the displayed mnemonic for the inverted
    versions. e.g. BEQ can be displayed as BNE.
  * The following JMP instruction that encodes the branch destination has
    been folded into the disassembly of the branch instruction. Unlike
    MIPS, I chose to display it offset from the branch check with =>
    instead of another comma.

9b81e0e597 16-byte align frames on the VMFrameStack
- Fixed: Don't assume operator new will return a pointer with 16-byte
  alignment when allocating a block for the VMFrameStack. Because it seems
  it's actually guaranteed to be 8-byte aligned. Don't know where I got
  the idea it would always be 16-byte aligned.

c6c2b21901 Add FxVMFunctionCall class
- This replaces the general extensibility that had existed formerly
  in thingdef_function.cpp. Parameter parsing for function calls is
  shared with state parameter parsing. Functions are defined exactly in
  the same way as action functions, but without the 'action' keyword.

b14f768b68 Fix FxPick code emission
- Fixed: Integer constants passed to pick() need to manually generate load
  instructions, since FxConstant::Emit() will just return a constant
  register with its value.
- Fixed: VMFunctionBuilder::RegAvailability::Reuse() didn't actually
  calculate a proper mask. Also added another assert to this function.

- Added register reuse to VMFunctionBuilder for FxPick's code emitter.
- Note to self: Need to reimplement IsPointerEqual and CheckClass, which
  were added to thingdef_function.cpp over the past year, as this file no
  longer exists in this branch.
