registers AMD64 provides, this routine still needs to be written as self-
modifying code for maximum performance. The additional registers do allow
for further optimization over the x86 version by allowing all four pixels
to be in flight at the same time. The end result is that AMD64 ASM is about
2.18 times faster than AMD64 C and about 1.06 times faster than x86 ASM.
(For further comparison, AMD64 C and x86 C are practically the same for
this function.) Should I port any more assembly to AMD64, mvlineasm4 is the
most likely candidate, but it's not used enough at this point to bother.
Also, this may or may not work with Linux at the moment, since it doesn't
have the eh_handler metadata. Win64 is easier, since I just need to
structure the function prologue and epilogue properly and use some
assembler directives/macros to automatically generate the metadata. And
that brings up another point: You need YASM to assemble the AMD64 code,
because NASM doesn't support the Win64 metadata directives.
- Added an SSE version of DoBlending. This is strictly C intrinsics.
VC++ still throws around unneccessary register moves. GCC seems to be
pretty close to optimal, requiring only about 2 cycles/color. They're
both faster than my hand-written MMX routine, so I don't need to feel
bad about not hand-optimizing this for x64 builds.
- Removed an extra instruction from DoBlending_MMX, transposed two
instructions, and unrolled it once, shaving off about 80 cycles from the
time required to blend 256 palette entries. Why? Because I tried writing
a C version of the routine using compiler intrinsics and was appalled by
all the extra movq's VC++ added to the code. GCC was better, but still
generated extra instructions. I only wanted a C version because I can't
use inline assembly with VC++'s x64 compiler, and x64 assembly is a bit
of a pain. (It's a pain because Linux and Windows have different calling
conventions, and you need to maintain extra metadata for functions.) So,
the assembly version stays and the C version stays out.
- Removed all the pixel doubling r_detail modes, since the one platform they
were intended to assist (486) actually sees very little benefit from them.
- Rewrote CheckMMX in C and renamed it to CheckCPU.
- Fixed: CPUID function 0x80000005 is specified to return detailed L1 cache
only for AMD processors, so we must not use it on other architectures, or
we end up overwriting the L1 cache line size with 0 or some other number
we don't actually understand.

that animated icons can be done with it.
- Changed FImageCollection to use a TArray to hold its data.
- Fixed: SetChanHeadSettings did an assignment instead of comparing
the channel ID witg CHAN_CEILING.
- Changed sound sequence names for animated doors to FNames.
- Automatically fixed: DCeiling didn't properly serialize its texture id.
- Replaced integers as texture ID representation with a specific new type
to track down all potentially incorrect uses and remaining WORDs used
for texture IDs so that more than 32767 or 65535 textures can be defined.
SVN r1036 (trunk)
They are not needed anywhere else.
- Changed the HackHack hack for corrupt 256 pixel high textures that
FMultiPatchTexture only calls a virtual function instead of doing any
type checks of the patch itself.
- Cleaned up the constant definitions in doomdata.h.
- Moved the TEXTUREx structures from doomdata.h to multipatchtexture.cpp
because they are used only in this one file.
- Removed some more typedefs from r_defs.h and doomdata.h
- Moved local polyobject data definitions from p_local.h to po_man.cpp.
SVN r1012 (trunk)
drawing function. The most improvement came from being able to turn some
constant variables into immediate values with self-modifying code, but I
also managed to reorder it to make it a little faster. It's about 9% faster
than VC++'s code and 19% faster than GCC's code. That's not a huge
improvement (for VC++), but at least it's measurable.
- Removed the solid fill "optimization" from rt_shaded4cols(), because in my
testing, it didn't help any and in fact, hurt just a little bit.
- In the name of simplification, all the rt_tlate* drawers were changed to do
the translation in one step and the drawing in another. This lets me call
the untranslated drawer to do the real drawing instead of mostly duplicating
them. Performance wise, there is practically no difference from before.
SVN r771 (trunk)
the exact same values as previous ZDoom versions
- Added a DECORATE 'stencilcolor' property so that the stencil render style
can be used.
- Added some NULL pointer checks to the font loading code.
SVN r713 (trunk)
- Added .txt files to the list of types (wad, zip, and pk3) that can be
loaded without listing them after -file.
- Fonts that are created by the ACS setfont command to wrap a texture now
support animated textures.
- FON2 fonts can now use their full palette for CR_UNTRANSLATED when drawn
with the hardware 2D path instead of being restricted to the game palette.
- Fixed: Toggling vid_vsync would reset the displayed fullscreen gamma to 1
on a Radeon 9000.
- Added back the off-by-one palette handling, but in a much more limited
scope than before. The skipped entry is assumed to always be at 248, and
it is assumed that all Shader Model 1.4 cards suffer from this. That's
because all SM1.4 cards are based on variants of the ATI R200 core, and the
RV250 in a Radeon 9000 craps up like this. I see no reason to assume that
other flavors of the R200 are any different. (Interesting note: With the
Radeon 9000, D3DTADDRESS_CLAMP is an invalid address mode when using the
debug Direct3D 9 runtime, but it works perfectly fine with the retail
Direct3D 9 runtime.) (Insight: The R200 probably uses bytes for all its
math inside pixel shaders. That would explain perfectly why I can't use
constants greater than 1 with PS1.4 and why it can't do an exact mapping to
every entry in the color palette.
- Fixed: The software shaded drawer did not work for 2D, because its selected
"color"map was replaced with the identitymap before being used.
- Fixed: I cannot use Printf to output messages before the framebuffer was
completely setup, meaning that Shader Model 1.4 cards could not change
resolution.
- I have decided to let remap palettes specify variable alpha values for
their colors. D3DFB no longer forces them to 255.
- Updated re2c to version 0.12.3.
- Fixed: A_Wander used threshold as a timer, when it should have used
reactiontime.
- Fixed: A_CustomRailgun would not fire at all for actors without a target
when the aim parameter was disabled.
- Made the warp command work in multiplayer, again courtesy of Karate Chris.
- Fixed: Trying to spawn a bot while not in a game made for a crashing time.
(Patch courtesy of Karate Chris.)
- Removed some floating point math from hu_scores.cpp that somebody's GCC
gave warnings for (not mine, though).
- Fixed: The SBarInfo drawbar command crashed if the sprite image was
unavailable.
- Fixed: FString::operator=(const char *) did not release its old buffer when
being assigned to the null string.
- The scanner no longer has an upper limit on the length of strings it
accepts, though short strings will be faster than long ones.
- Moved all the text scanning functions into a class. Mainly, this means that
multiple script scanner states can be stored without being forced to do so
recursively. I think I might be taking advantage of that in the near
future. Possibly. Maybe.
- Removed some potential buffer overflows from the decal parser.
- Applied Blzut3's SBARINFO update #9:
* Fixed: When using even length values in drawnumber it would cap to a 98
value instead of a 99 as intended.
* The SBarInfo parser can now accept negatives for coordinates. This
doesn't allow much right now, but later I plan to add better fullscreen
hud support in which the negatives will be more useful. This also cleans
up the source a bit since all calls for (x, y) coordinates are with the
function getCoordinates().
- Added support for stencilling actors.
- Added support for non-black colors specified with DTA_ColorOverlay to the
software renderer.
- Fixed: The inverse, gold, red, and green fixed colormaps each allocated
space for 32 different colormaps, even though each only used the first one.
- Added two new blending flags to make reverse subtract blending more useful:
STYLEF_InvertSource and STYLEF_InvertOverlay. These invert the color that
gets blended with the background, since that seems like a good idea for
reverse subtraction. They also work with the other two blending operations.
- Added subtract and reverse subtract blending operations to the renderer.
Since the ERenderStyle enumeration was getting rather unwieldy, I converted
it into a new FRenderStyle structure that lets each parameter of the
blending equation be set separately. This simplified the set up for the
blend quite a bit, and it means a number of new combinations are available
by setting the parameters properly.
SVN r710 (trunk)
- Modified M_DrawFrame() and R_DrawTopBorder() so that they call FlatFill() to
draw the edges of the frames. This at least seems a bit faster for hardware
2D.
- Implemented FlatFill() for D3DFB. It seems to be exactly as fast as the
default implementation that just calls DrawTexture() to tile the pieces onto
the screen, so I'm not sure it was worth the bother.
SVN r686 (trunk)
shader seems to be producing crappy output, so it's disabled for now.
Specifically, it produces distorted output at regular intervals for
textures that aren't power-of-2-sized, and it's still doing visible
filtering when the texture is rendered at its original size, so
obviously it's not doing something right.
- Fixed the use of power-of-2-sized native textures for smaller game
textures again.
- Fixed: D3DFB did not restore all the state it needed to after resetting
the device.
- Fixed: R_DrawTopBorder() must clip itself around the 3D view, since it's
now drawn later.
- With full software rendering, palette flashes once again effect the whole
screen.
Changes I neglected to put in the previous commit log:
- Moved the view border drawing into the 2D mode part. When using Begin2D()
now, the only part of the software buffer that gets updated to the screen
is the part with the actual 3D scene and only if you tell it to.
- Fixed a D3D memory leak on every frame in windowed mode and the same thing
for the screen wipes. Note to self: If it's an interface, be sure to
Release it, because it will be AddRef'ed before being returned to you.
- Moved the BlendView() call out of FBaseStatusBar::Draw() so that it can be
applied before copying the 3D scene to the screen underneath the 2D parts.
- Restored the console's darkening level to its old table-based amount.
- Fixed D3DFB::SetColorOverlay()'s incorrect calculations.
- Fixed the D3D screen wipes for letterboxed modes.
SVN r662 (trunk)
- Moved the common code of ACS and DECORATE translation generation into the
FRemapTable class.
- Fixed: The DECORATE translation code was not changed for the new data structures.
- Expanded range of ACS and DECORATE translations to 65535.
- Fixed: R_CopyTranslation was not altered for the new functionality.
I removed the function and replaced the one use with a simple assignment.
SVN r644 (trunk)
palettes smaller than 256 entries with the shader I wrote for it. Is there
a list of gotchas like this listed some where? I'd really like to see it.
Well, when compiled with SM2.0, the PalTex shader seems to be every-so-
slightly faster on my GF7950GT than the SM1.4 version, so I guess it's a
minor win for cards that support it.
- Fixed: ST_Endoom() failed to free the bitmap it used.
- Added the DTA_ColorOverlay attribute to blend a color with the texture
being drawn. For software, this (currently) only works with black. For
hardware, it works with any color. The motiviation for this was so I could
rewrite the status bar calls that passed DIM_MAP to DTA_Translation to
draw darker icons into something that didn't require making a whole new
remap table.
- After having an "OMG! How could I have been so stupid?" moment, I have
removed the off-by-one check from D3DFB. I had thought the off-by-one error
was caused by rounding errors by the shader hardware. Not so. Rather, I
wasn't sampling what I thought I was sampling. A texture that uses palette
index 255 passes the value 1.0 to the shader. The shader needs to adjust the
range of its palette indexes, or it will end up trying to read color 256
from the palette texture when it should be reading color 255. Doh!
- The TranslationToTable() function has been added to map from translation
numbers used by actors to the tables those numbers represent. This function
performs validation for the input and returns NULL if the input value
is invalid.
- Major changes to the way translation tables work: No longer are they each a
256-byte array. Instead, the FRemapTable structure is used to represent each
one. It includes a remap array for the software renderer, a palette array
for a hardware renderer, and a native texture pointer for D3DFB. The
translationtables array itself is now an array of TArrays that point to the
real tables. The DTA_Translation attribute must also be passed a pointer
to a FRemapTable, not a byte array as previously.
- Modified DFrameBuffer::DrawRateStuff() so that it can do its thing properly
for D3DFB's 2D mode. Before, any fullscreen graphics (like help images)
covered it up.
SVN r640 (trunk)
passing renderer specific data to the function. Also added DTA_Font so
that the renderer can fetch font translations from the proper font.
DIM_MAP/ConShade had to be made a regular translation table to make it
work.
- Added Karate Chris's fix for scoreboard displaying team play related data
in non teamplay games.
- Fixed: The team selection menu didn't work.
- Fixed: UpdateTeam passed an FString to Printf.
SVN r623 (trunk)
- Added a new color parameter to DCanvas::Clear() that specifies the
ARGB value of the color. This is used if the old color parameter,
which specifies a palette entry, is -1.
SVN r617 (trunk)
MAPINFO keyword 'bordertexture' and are settable per map.
- Fixed: When used in DECORATE A_Explode must use A_ExplodeParms.
- Added custom label support to A_Chase. To enable resurrection from the
customizable version I also moved all A_VileChase stuff into p_enemy.cpp.
SVN r437 (trunk)
- The stat meters now return an FString instead of sprintfing into a fixed
output buffer.
- NOASM is now automatically defined when compiling for a non-x86 target.
- Some changes have been made to the integral types in doomtype.h:
- For consistancy with the other integral types, byte is no longer a
synonym for BYTE.
- Most uses of BOOL have been change to the standard C++ bool type. Those
that weren't were changed to INTBOOL to indicate they may contain values
other than 0 or 1 but are still used as a boolean.
- Compiler-provided types with explicit bit sizes are now used. In
particular, DWORD is no longer a long so it will work with both 64-bit
Windows and Linux.
- Since some files need to include Windows headers, uint32 is a synonym
for the non-Windows version of DWORD.
- Removed d_textur.h. The pic_t struct it defined was used nowhere, and that
was all it contained.
SVN r326 (trunk)
- Fixed: Friendlies would not turn to face you when you engaged them in
conversation, nor would they reliably return to their original facing when
you stopped talking to them.
- Added deprecation warnings for the DontHurtShooter, ExplosionRadius, and
ExplosionDamage actor "properties." They were considered deprecated before;
now this is explicitly stated when they are used. The problem with them is
that they are not really properties and do not behave like other properties
and cannot be inherited, because they are really just an alternate way of
specifying parameters for A_Explode. (Anything that currently prints a
deprecation warning will be removed completely in 2.2.0, which will be the
version where custom state labels make their debut.)
SVN r272 (trunk)
so now it is available in all games.
- Replaced the call to A_FlameSnd in the HereticPlayer's burn death sequence
with A_FireScream and defined *burndeath for Heretic.
- Added Grubber's custom player class support.
SVN r250 (trunk)
- Added support for wrapping midtextures vertically.
- Since zdoom.wad is now zdoom.pk3, the default mapinfos can use full pathnames.
So now they do.
- Fixed: The DSimpleCanvas constructor used a pitch too narrow on screens wider
than 640 pixels when using a non-AMD processor and the processor's L1 cache
line size could not be determined. I think this should fix the issue of
weirdly rendered 8 pixel wide borders on the left and right of the screen that
some people experienced.
- Fixed: The secnodes were never freed.
SVN r93 (trunk)
- Fixed: FDoomEdMap needed a destructor.
- Fixed: Decal animators were never freed.
- Fixed: Colormaps were never freed.
- Fixed: Memory allocated in R_InitTranslationTables() was never freed.
- Fixed: R_InitParticles() allocated way more memory than it needed to. (And the
particle memory was never freed, either.)
- Fixed: FMetaTable::FreeMeta() should use delete[] to free string metadata.
- Fixed: FConfigFile::ClearCurrentSection() must cast the entry to a char *
before deleting it, because that's the way it was allocated.
- Fixed definitions of DeadZombieMan and DeadShotgunGuy in doom/deadthings.txt.
Skip_super resets the dropitem list, so having it after "DropItem None" is
pointless.
- Fixed: Decorate DropItem information was never freed.
- Fixed: FinishStates() allocated even 0-entry state arrays.
- Fixed: Default actor instances were never freed.
- Fixed: FRandomSoundList never freed its sound list.
- Fixed: Level and cluster strings read from MAPINFO were never freed.
- Fixed: Episode names were never freed.
- Fixed: InverseColormap and GoldColormap were never freed. Since they're always
allocated, they can just be arrays rather than pointers.
- Fixed: FFont destructor never freed any of the character data or the font's name.
- Fixed: Fonts were not freed at exit.
- Fixed: FStringTable::LoadLanguage() did not call SC_Close().
- Fixed: When using the -iwad parameter, IdentifyVersion() did not release the
buffer it created to hold the parameter's path.
