That only leaves the Scale function which is still being used in a few places and which would create considerably worse code without assembly on 32 bit platforms. This is also far too primitive (2 or 3 assembly instructions) to claim any copyright on it, so I think m_fixed.h can now be considered free of Build-related issues. The deficated inline headers have been removed because that sole remaining function could be easily moved into m_fixed.h.
This was used in only 4 places, 3 of which could easily be replaced with a memset, and the fourth, in the Strife status bar, suffering from a pointless performance optimization, rendering the code unreadable - the code spent here per frame is utterly insignificant so clarity should win here.
- merged the FrontBlock searcher for the Bloodscourge into RoughMonsterSearch. This also fixes the bug that the searcher was not initialized properly for the MageBoss.
Interesting tidbit: The damage calculation in P_MinotaurSlam had been incorrect for the Heretic version since the friendly Hexen Dark Servant was added, but nobody ever noticed in 14 years...
- 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.
- 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.
This required some changes to the Trace function because it turned out that the original was incapable of collecting the required information:
* actors are now also linked into blockmap blocks on both sides if they occupy the boundary of a sector portal.
* Trace will no longer set up parallel traces in all parts connected with sector portal, but only use one trace and relocate that on the actual boundary.
This will fail when a trace starts directly on a block boundary in which case x is a whole number. It should always use 'floor(x)+1' to ensure that the calculated point is at the right or upper edge of a block.
* we do not really need compatibility PointOnLineSide here. Unlike the movement code it'd only affect some extreme edge cases.
* removed the special case for very short traces. This was a result of the original and very imprecise PointOnLine functions. Since those no longer get used here and floating point precision is a lot higher there is no need for this kind of treatment.
* PointOnLine checks for the sides of an actor's bounding box don't need a full PointOnLineSide call, a simple coordinate comparison is fully sufficient, and this can easily be done in the existing switch/case block.
* typo in calculating end position from a trace vector
* must use floor to convert from floating point block coordinate to block index to account for running off the negative side of the blockmap. (Int cast always rounds toward zero which is wrong here.)
* bad calculation of sight checking slopes - they has the actor's z coordinate duplicated.
- fixed scaling of automap markers.
- Converted P_MovePlayer and all associated variables to floating point because this wasn't working well with a mixture between float and fixed.
Like the angle commit this has just been patched up to compile, the bulk of work is yet to be done.
Links through sector portals are not done because nearly all the checks can be performed without doing this so if it works without there's no need to add more processing time.
Will have to see if there's cases left where such a link is needed and if so, whether there's better options to do it.
For line portals such links are necessary to have proper collision detection with actors that are currently transitioning the portal.
