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.
SVN r1134 (trunk)
- Added: fullscreenoffsets flag for status bars. This changes the coordinate
system to be relative to the top left corner of the screen. This is useful
for full screen status bars.
- Changed: drawinventorybar will use the width of artibox or invcurs (strife)
to determine the spacing. Let me know if this breaks any released mods.
- Fixed: If a status bar height of 0 was specified in SBarInfo the wrong bar
would be shown.
- Fixed: If a static inventory bar was used the user still had to press invuse
in order to get rid of the "overlay".
- Fixed: forcescaled would not work if the height of the bar was 0.
- Added: keyslot to drawswitchableimage.
- Fixed: The transition effects for the log and keys popups were switched.
SVN r1116 (trunk)
surprised if this doesn't build in Linux right now. The CMakeLists.txt
were checked with MinGW and NMake, but how they fair under Linux is an
unknown to me at this time.
- Converted most sprintf (and all wsprintf) calls to either mysnprintf or
FStrings, depending on the situation.
- Changed the strings in the wbstartstruct to be FStrings.
- Changed myvsnprintf() to output nothing if count is greater than INT_MAX.
This is so that I can use a series of mysnprintf() calls and advance the
pointer for each one. Once the pointer goes beyond the end of the buffer,
the count will go negative, but since it's an unsigned type it will be
seen as excessively huge instead. This should not be a problem, as there's
no reason for ZDoom to be using text buffers larger than 2 GB anywhere.
- Ripped out the disabled bit from FGameConfigFile::MigrateOldConfig().
- Changed CalcMapName() to return an FString instead of a pointer to a static
buffer.
- Changed startmap in d_main.cpp into an FString.
- Changed CheckWarpTransMap() to take an FString& as the first argument.
- Changed d_mapname in g_level.cpp into an FString.
- Changed DoSubstitution() in ct_chat.cpp to place the substitutions in an
FString.
- Fixed: The MAPINFO parser wrote into the string buffer to construct a map
name when given a Hexen map number. This was fine with the old scanner
code, but only a happy coincidence prevents it from crashing with the new
code
- Added the 'B' conversion specifier to StringFormat::VWorker() for printing
binary numbers.
- Added CMake support for building with MinGW, MSYS, and NMake. Linux support
is probably broken until I get around to booting into Linux again. Niceties
provided over the existing Makefiles they're replacing:
* All command-line builds can use the same build system, rather than having
a separate one for MinGW and another for Linux.
* Microsoft's NMake tool is supported as a target.
* Progress meters.
* Parallel makes work from a fresh checkout without needing to be primed
first with a single-threaded make.
* Porting to other architectures should be simplified, whenever that day
comes.
- Replaced the makewad tool with zipdir. This handles the dependency tracking
itself instead of generating an external makefile to do it, since I couldn't
figure out how to generate a makefile with an external tool and include it
with a CMake-generated makefile. Where makewad used a master list of files
to generate the package file, zipdir just zips the entire contents of one or
more directories.
- Added the gdtoa package from netlib's fp library so that ZDoom's printf-style
formatting can be entirely independant of the CRT.
SVN r1082 (trunk)
- Changed: Players don't telefrag when they are spawned now but after all
actors have been spawned to avoid accidental voodoo doll telefragging.
- Fixed: ACS scripts for non-existent maps were started on the current one.
- Added a 'wallbouncefactor' property to AActor.
- Reverted forceunderwater change from r1026 and fixed the problem for real:
SECF_FORCEDUNDERWATER only has meaning when coming from the heightsec.
So the initial check of the current sector in AActor::UpdateWaterLevel
must only check for SECF_UNDERWATER, not SECF_UNDERWATERMASK.
SVN r1027 (trunk)
into a single place.
- Fixed: Setting an invalid mug shot state crashed the game.
- Fixed my attempts to be clever with strings yesterday.
SVN r1009 (trunk)
of type MiscPatch with the same name.
- Added UDMF line trigger types MonsterUse and MonsterPush.
- Separated skill and class filter bits from FMapThing::flags so that
UDMF can define up to 16 of each. Also separated easy/baby and
hard/nightmare and changed default MAPINFO definitions.
- Changed: Crosshair drawing uses the current player class's default health instead
of 100 to calculate the color for the crosshair.
- Added SECF_NOFALLINGDAMAGE flag plus Sector_ChangeFlags to set it. Also separated
all user settable flags from MoreFlags into their own Flags variable.
SVN r964 (trunk)
- reverted removal of AddPatch call in crosshair initialization.
- Modified makewad.c so that it doesn't write file names with '[]^' to the dependency file. Apparenly make
can't handle these names and an incomplete list is still better than something that doesn't work at all.
SVN r719 (trunk)
- Got rid of R_InitPatches because the new texture init code needs to preload
everything to work correctly.
- Rewrote texture manager initialization to order textures primarily by WAD
rather than by type. This way later textures will always override earlier
ones. The only exception is that TEX_MiscPatch are only used as a fallback
if nothing else can be found.
- Optimized the tryany case of FTextureManager::CheckForTexture. It is not
necessary to scan the hash chain twice. The required information can be
retrieved during the first pass as easily and even offers a little more
control.
- Made FFont destructor virtual.
- Added 'Ice' translation to DECORATE.
(Caution: Not fully tested yet!)
SVN r715 (trunk)
* Fixed: Drawbar had a few memory leaks.
- Added another temporary cvar called pc to play with the multipiler used by D3DFB::SetPaletteTexture().
SVN r704 (trunk)
truncate the coordinates to integers before sending them to the hardware.
Otherwise, there can be one pixel gaps compared to the software renderer,
because the hardware is rounding to nearest but the software renderer is
simply truncating the fractional part of the coordinate. This is the real
cause of the gap above the status bar at 1152x864 (and another gap to the
left of the status bar at 800x500).
- Fixed: When D3DFB::DrawTextureV had to clip a tile, it adjusted the
texture coordinates erroneously, still using the old calculations from
before texture packing was implemented.
SVN r695 (trunk)
will also double as the pistol's icon in the AltHUD.
- Added a generic log display that can show Strife's log messages in all games
regardless of the current game, active status bar and HUD mode.
- Added GZDoom's alt HUD.
SVN r693 (trunk)
can share the same hardware texture. This greatly reduces the number of
DrawPrimitive calls that need to be made when drawing text (or any 2D
graphics in general), so now hardware text is much faster than software text
all around. (As an example, one scenario went from 315 fps to over 1635 fps
for hardware, compared to 540 fps for software.)
SVN r687 (trunk)
- Bumped the maximum resolution up to 2560x1600.
- Fixed: DCanvas::DrawTexture() only expanded virtual screen sizes for widescreen
resolutions but left 5:4 modes alone. This fix neccessitated the addition of
DTA_Bottom320x200 for the status bar to use so that it could be flush with the
bottom of the screen rather than sitting slightly above it.
- Fixed: FConfigFile::ReadConfig()'s definition of whitespace was too broad.
- Fixed: Defining custom translation ranges in descending order and/or with gaps
made for crashes.
SVN r676 (trunk)
players are on teams.
- Set TEAM_None back to 255. Since a player's team has already been accessible
through ACS, needlessly redefining this is a bad thing to do, since it can
break existing maps. 255 different teams should still be more than enough.
- Fixed: At certain resolutions, there was a one pixel row between the status
bar and the rest of the screen, thanks to rounding error.
- Added automatic batching of quads to D3DFB. Screens with a lot of text are
ever-so-slightly faster now, though still only about half the speed of
sofware-only text. I suppose the only way to see a marked improvement is
going to be by stuffing multiple glyphs in a single texture.
- Fixed: Crosshairgrow's animation was not framerate-independent.
SVN r668 (trunk)
since I couldn't think of any reason why it should be grabbed at any other
time. (This only applies to windowed mode, where it makes sense to let the
OS have control of the pointer.)
SVN r661 (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)
DCanvas::DrawTexture() to calculate off the actual bottom of the image
instead of the height, improving precision. Now the scaled status bar is
flush with the bottom of the screen at 1280x1024, for instance.
SVN r458 (trunk)
warnings. At first, I was going to try and clean them all up. Then I decided
that was a worthless cause and went about just acting on the ones that
might actually be helpful:
C4189 (local variable is initialized but not referenced)
C4702 (unreachable code)
C4512 (assignment operator could not be generated)
SVN r420 (trunk)
with an FString now.
- Fixed: The music strings in the default level info were never freed and
caused memory leaks when used repeatedly.
- Fixed: The intermusic string in the level info was never freed.
- Fixed: The default fire obituary should only be printed if the damage
came from the environment. If it comes from a monster the monster specific
obituary should be used instead.
- Added custom damage types from the floating point test release.
- Changed Pain Elemental's massacre check. Now A_PainDie checks for the damage
type and doesn't spawn anything if it is NAME_Massacre. A_PainDie can also
be used by other actors so a more generalized approach is needed than hard
coding it into the Pain Elemental.
- Converted a few of Doom's monsters to DECORATE because I couldn't test the
first version of the custom state code with the corpses inheriting from them.
- Added custom states from last year's floating point test release and fixed
some bugs I found in that code. Unfortunately it wasn't all salvageable
and it was easier to recreate some parts from scratch.
SVN r368 (trunk)
on the automap instead. If its first argument is zero, the map marker itself
appears on the automap, otherwise it is drawn on top of any actor with a TID
matching that argument. If the second argument is one, then the map marker
will only be appear if the player has previously seen the sector it is one.
You can use Thing_Activate and Thing_Deactivate on markers to turn them on
and off. And if you subclass MapMarker with DECORATE, you can easily make
your own custom markers.
- Fixed: Map markers could not be drawn partially off the map. They were
drawn either fully or not at all.
- Fixed: Map markers appeared in the wrong place on a rotated overlay map if
screenblocks < 10.
SVN r356 (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)
ReplaceTextures (str old_texture, str new_texture, optional bool not_lower,
optional bool not_mid, optional bool not_upper, optional bool not_floor,
optional bool not_ceiling); and
SectorDamage (int tag, int amount, str type, bool players_only, bool in_air,
str protection_item, bool subclasses_okay);
- Added the vid_nowidescreen cvar to disable widescreen aspect ratio
correction. When this is enabled, the only display ratio available is 4:3
(and 5:4 if vid_tft is set).
- Added support for setting an actor's damage property to an expression
through decorate. Just enclose it within parentheses, and the expression
will be evaluated exactly as-is without the normal Doom damage calculation.
So if you want something that does exactly 6 damage, use a "Damage (6)"
property. To deal normal Doom missile damage, you can use
"Damage (random(1,8)*6)" instead of "Damage 6".
- Moved InvFirst and InvSel into APlayerPawn so that they can be consistantly
maintained by ObtainInventory.
SVN r288 (trunk)
ceiling and floor of the front sector, the renderer did not add it to the
solid clip list.
- Blends created with the ACS fade commands now degrade to transparent overlays
when the console is visible, just as they do for the menu.
SVN r240 (trunk)
for direct descendants of AWeapon and not for every weapon being defined.
- Changed parsing of actor names back to not use C-mode. This change breaks
any definition that contain periods in their name and apparently there's
more than anyone could expect. Also altered the parser to manually check
for colons inside the parsed string so that placing spaces around them
is no longer necessary.
- Fixed: Weapons could be picked up for ammo even if they gave none.
- Fixed: A_Beacon was missing a NULL pointer check for the beacon's owner.
- Fixed: The status bar tried to access CPlayer->camera without checking
its validity. In spy mode there is a possibility that it is NULL.
SVN r237 (trunk)
- Fixed map name checks in idclev, hxvisit, for +map and the titlemap.
- Changed handling of Zips so that the patches/, graphics/, sounds/ and
music/ subdirectories no longer are placed in the global namespace. Instead
new namespaces are defined. These namespaces aren't merged, however and
searching in them either returns a lump inside it or one from the global
namespace when it doesn't come from a Zip file. Proper order of files is
still observed though. As a result proper use of the directories inside Zips
is strictly enforced now so that for example anything used as a patch must be
in the patches/ directory and won't be found anywhere else.
SVN r199 (trunk)
your head has popped off your body.
- Fixed: When item respawning is on and you play on skill 1 or 5, picking
up ammo would permanently double the amount of ammo received from that
item the next time it gets picked up.
- Added a check to PlayerIsGone() for players who have already had their
actors destroyed before calling it.
- Fixed: G_CheckDemoStatus() only restored your name, autoaim, and color
settings after playing back a demo.
- Added DEM_SPRAY net command so that sprayed decals work in multiplayer
and demos.
- Changed DEM_GIVECHEAT to use a word for specifying the item quantity.
This is useful mainly for giving yourself more than 255 health at a time.
- Fixed: DEM_SUMMONFRIEND was not handled by Net_SkipCommand().
SVN r58 (trunk)
STlib_drawNum(), and FDoomStatusBarTexture::DrawToBar() should add
the textures left offset to the x coordinate before drawing.
These fix Twice Risen's status bar.
- Changed: VPrintf now uses string.VFormat(), instead of vsprintf().
SVN r53 (trunk)
