66d287ea81 - fixed: Stepping through a ceiling portal on a two-sided line did not work. 
- fixed: Stepping up an actor checked against the sector's own ceiling, even if it was a crossable portal.

ed141943e1 - removed use of BestColor_MMX because there is no measurable improvement at all on a modern system. On top of that this function does not get called nearly often enough to justify the hassle. Like DoBlending this would require hundreds of calls per frame to make any impact that would be measurable. 2016-12-07 14:40:19 +01:00

5910067c44 - discontinue using the MMX assembly version of DoBlending. 
Some benchmarking shows that on SSE systems it only harms performance and compared to the intrinsics version the gains are too marginal for something this infrequently called.
Doing 100000 calls of DoBlending results in a 5 ms decrease of using assembly vs intrinsics on a 3.4 GHz Core i7, meaning that even on a computer that is 10x slower you can still do 1000 or so blends per frame without a speed hit.

42346c58d3 - disabled assembly entirely to make the MT drawer submission compile. 
This still requires a review of the two non-drawer functions that get 'lost'.

52645afb4b - for the time being, make ZScript command line switch locked so that everybody understands that it's not ready for use in released mods yet. 2016-12-06 22:42:10 +01:00

b2d1b0d7a6 - fixed: FTranslatedLineTarget::angleFromSource returned the attack angle, not the angle between actors when returned from P_LineAttack. 
For most attack functions this is wrong, it's only the Hexen fighter attack needing this particular value, so it has been split up into two return values now.

092461ed34 - make dynamic object casts a dedicated VM instruction instead of a builtin function. 
This can see some heavy use in iterators where saving several hundreds of function calls can be achieved. In these cases, using a function to do the job will become a significant time waster.

f722967abe - added automatic type deduction capabilities for local variables. If you type 'let variable = value;' the type of 'variable' will be deduced from the given value. This is mostly of interest for type casting pointers, because 'let p = Classtype(objectvar);' does not require writing the class type name twice. 2016-12-05 13:24:42 +01:00

f6fb27b683 - deleted rt_copy*col and rt_map*col assembly versions after running benchmarks that show inferior performance to the C++ versions on both older and newer CPUs. 2016-12-05 00:46:58 +01:00

86fcc3fd21 - added a heavily optimized version of vlinec4 for x64. The original loaded everything from the global variables. While this is acceptable in 32 bit code because it has an immediate register load instruction, for 64 bit this does not exist. Accessing these variables from the stack or a register doubles the execution speed of this function and on a Core i7-3770 from 2012 is even faster than the assembly version. Right now the assembly version is still there, pending a benchmark run on an older 64 bit system. 2016-12-04 23:53:36 +01:00

f4454d2e00 - minor, but very effective optimization for R_DrawSpanMasked: Do not store the texel value in a byte. Store it in a local int variable. This allows the compiler to read it with a zero extending instruction instead of using a byte reading instruction and then later having it to convert to an int anyway. This removes one instruction from the loop which results in a 10% performance increase on 32 bit. 2016-12-04 19:32:54 +01:00

c9caaf08c8 - removed asm version of R_DrawFuzzColumn, because even on my 9 year old laptop this was significantly slower than the C version. 2016-12-04 18:38:38 +01:00
Christoph Oelckers
13efb34964 - removed the asm version of R_DrawColumn because it doesn't provide any significant benefit. 
On modern systems it is actually slower than the C version, only on old ones it is marginally faster - but the overall execution time for this function is so low that even in the worst case scenario the minor loss of performance on older systems is still not relevant.

93163d12f1 - removed R_DrawColumnHorizP_ASM completely after discovering that the compiler generated code isn't really anything worse than the old assembly code. This looks like something that may have been relevant 10 years ago but today it looks like there's no need for hand optimization here anymore. And since it appears to be broken anyway, off this goes. 2016-12-04 15:31:08 +01:00

c99a051a2a - Added lambda feature to FString::(Strip|Replace)Chars. 
Use it in the other (Strip|Replace)Chars methods to show how it would work.

94287518e0 - added a virtual CanCollideWith script method that can be overridden to do class specific collision checks. 
This will get called for both actors taking part in a collision, if one of the two calls returns false it will immediately abort PIT_CheckThing with no collision taking place at all.

5117b32431 - fixed: The math for emulating the old slop overflow was not correct and made the affected sectors in void.wad display incorrectly. 
- set compat_polyobj for void.wad because its polyobjects glitch quite a bit with the normal setting.
 2016-12-03 14:42:06 +01:00

28604bad62 - fixed: The polyobject init specials must be cleared after Polyobject initialization is done, because they can block usage of regular lines colinear with the polyobject 2016-12-03 14:06:51 +01:00

0da233a664 changed ZScript include mechanism. 
* It will now use #include, just like most other definition formats and can be mixed with regular definitions. However, due to how the Lemon-generated parser works this will not recursively pull in all files, but store them in a list and process them sequentially. Functionally this shouldn't make a difference, because ZScript is mostly order-independent - the only thing where order is important is native classes, but these are completely internal to zdoom.pk3 where proper order is observed.

136e976b2a - added an error check for duplicate local variable definitions. 
Note that this only applies if both are in the same block. Just like in C++, it is perfectly legal to have the same variable name in two different nested scopes.

b3783a3850 redid the exception mechanism for script-side access violations to be of more use for diagnosing problems. 
The original implementation just printed a mostly information-free message and then went on as if nothing has happened, making it ridiculously easy to write broken code and release it. Changed it to:

* Any VMAbortException will now terminate the game session and go back to the console.
* It will also print a VM stack trace with all open functions, including source file and line numbers pointing to the problem spots. For this the relevant information had to be added to the VMScriptFunction class.

An interesting effect here was that just throwing the exception object increased the VM's Exec function's stack size from 900 bytes to 70kb, because the compiler allocates a separate local buffer for every single instance of the exception object.
The obvious solution was to put this part into a subfunction so that it won't pollute the Exec function's own stack frame. Interesting side effect of this: Exec's stack requirement went down from 900 bytes to 600 bytes. This is still on the high side but already a lot better.
