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.

Karate Chris.
- Added several type checks to the weapon slot code.
- Changed: Players no longer respawn in instant death sectors with
the 'Respawn where died' flag on.
SVN r1101 (trunk)
CMake 2.4, since the distros don't seem to consider 2.6 stable yet.
As a bonus, GTK+ is no longer a required dependency; now it's optional.
- Made dehsupp ignore CR characters, so it doesn't spew warnings on Linux.
SVN r1092 (trunk)
- Added a check for PUFFGETSOWNER to A_BFGSpray.
- Moved the PUFFGETSOWNER check into P_SpawnPuff and removed the limitation
to players only.
- Fixed: P_SpawnMapThing still checked FMapThing::flags for the class bits
instead of FMapThing::ClassFilter.
- Fixed: A_CustomMissile must not let P_SpawnMissile call P_CheckMissileSpawn.
It must do this itself after setting the proper owner.
- Fixed: CCMD(give) increased the total item count.
- Fixed: A_Stop didn't set the player specific variables to 0.
SVN r1066 (trunk)
not work
- Added: PowerupTime to drawnumber and drawbar. You must specify a
powerupgiver. Although drawnumber goes in seconds the powerup has left
drawbar will use ticks for extra accuracy.
- I have increased cross-port compatibility with Skulltag. If an unknown
game mode is provided for sbarinfo's gamemode command it will ignore it and
continue.
SVN r1015 (trunk)
capturing the mouse.
- Changed: Telefragging should not thrust the victim if it isn't in precisely the
same position as the killer.
- fixed: A_SpawnItemEx must call P_TeleportMove before checking the spawned
object's position.
SVN r1014 (trunk)
channel when restarting the song, rather than emitting a single note off
event which only has a 1 in 127 chance of being for a note that's playing
on that channel. Then I decided it would probably be a good idea to reset
all the controllers as well.
- Increasing the size of the internal Timidity stream buffer from 1/14 sec
(copied from the OPL player) improved its sound dramatically, so apparently
Timidity has issues with short stream buffers. It's now at 1/2 sec in
length. However, there seems to be something weird going on with
corazonazul_ff6boss.mid near the beginning where it stops and immediately
restarts a guitar on the exact same note.
- Added a new sound debugging cvar: snd_drawoutput, which can show various
oscilloscopes and spectrums.
- Internal TiMidity now plays music.
- Changed the progdir global variable into an FString.
SVN r900 (trunk)
DECORATE was wrong (2 instead of 1.)
- Changed: Hexen set every cluster to be a hub if it hadn't been defined before
a level using this cluster. Now it will only do that if HexenHack is true,
i.e. when original Hexen format MAPINFOs are parsed. For ZDoom format
MAPINFOs it will now be the same as for the other games which means that
'hub' has to be declared explicitly.
- Added an Idle state that is entered in place of the spawn state if a monster
has to return to its inactive state if it can't find any more targets.
- Added MF5_NOINTERACTION flag which completely disables all physics related
code for any actor with this flag. Mostly useful for particle effects where
the actors just move a certain distance and then disappear.
- Removed the last remains of the antialias precalculation code from
am_map.cpp because it was no longer used.
- Fixed: Two-sided lines bordering a secret sector were not drawn in the
proper color
- Fixed: The automap didn't check ACS_LockedExecuteDoor for its lock color.
SVN r876 (trunk)
set to NULL before performing the delete. Otherwise, in some abnormal
situations, it could happen that the destroyed screen object is still
being accessed.
- Fixed: V_Shutdown didn't set OF_YesReallyDelete before deleting screen.
SVN r870 (trunk)
that the drivers will treat a BackBufferCount of 0 as a request for
double buffering.
- Fixed: Unsetting a cvar did not remove it from the list of tab
completions.
- Added "" as a synonym for "nullimage" in SBARINFO.
- Fixed: MAKESAVESIG's stringifier in version.h did not work as expected.
It stringified the passed macro name, not the value of the macro.
- Moved DCajunMaster off the DObject hierarchy.
- Changed DCajunMaster::getspawned into a TArray of FStrings. It was
mysteriously being left pointing to uninitialized memory during the
final GC at exit and crashing.
- Fixed: The code that removed hexdd.wad from the list of IWADs when
hexen.wad was not present did not work.
SVN r861 (trunk)
- Removed movie volume from the sound menu and renamed some of the other
options to give the MIDI device name more room to display itself.
- Moved the midi device selection into the main sound menu.
- Added FMOD as MIDI device -1, to replace the MIDI mapper. This is still the
default device. By default, it uses exactly the same DLS instruments as the
Microsoft GS Wavetable Synth. If you have another set DLS level 1 patch set
you want to use, set the snd_midipatchfile cvar to specify where it should
load the instruments from.
- Changed the ProduceMIDI function to store its output into a TArray<BYTE>.
An overloaded version wraps around it to continue to supply file-writing
support for external Timidity++ usage.
- Added an FMOD credits banner to comply with their non-commercial license.
- Reimplemented the snd_buffersize cvar for the FMOD Ex sound system. Rather
than a time in ms, this is now the length in samples of the DSP buffer.
Also added the snd_buffercount cvar to offer complete control over the
call to FMOD::System::setDSPBufferSize(). Note that with any snd_samplerate
below about 44kHz, you will need to set snd_buffersize to avoid long
latencies.
- Reimplemented the snd_output cvar for the FMOD Ex sound system.
- Changed snd_samplerate default to 0. This now means to use the default
sample rate.
- Made snd_output, snd_output_format, snd_speakermode, snd_resampler, and
snd_hrtf available through the menu.
- Split the HRTF effect selection into its own cvar: snd_hrtf.
- Removed 96000 Hz option from the menu. It's still available through the
cvar, if desired.
- Fixed: If Windows sound init failed, retry with DirectSound. (Apparently,
WASAPI doesn't work with more than two speakers and PCM-Float output at the
same time.)
- Fixed: Area sounds only played from the front speakers once you got within
the 2D panning area.
SVN r854 (trunk)
of the frame buffer so I can get rid of the last remaining renderer check
outside the display code in GZDoom.
- made V_SetResolution a virtual function in IVideo. It's probably not a perfect
solution but at least it allows overriding it (which I need in GZDoom.)
Note: There's a lot of redundancy between hardware.cpp/h in the SDL and Win32
folders so some cleaning up might be a good idea.
SVN r692 (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)
- fixed: The brown Chaos Serpent in Hexen had an incorrect sprite for its
ice death sequence set.
- fixed: Ammo upon game start does not get multiplied when on easy skill.
Implementing this as an inventory flag IF_IGNORESKILL also allows to create
ammo/weapon/backpack types that don't multiply the ammo given when on this
skill.
- moved Doom exit sounds into SNDINFO as $random definitions.
- Fixed: Dying Lost Souls could be reset to their see state if they slammed into
something.
SVN r540 (trunk)
- Fixed: DECORATE color translations with explicit colors didn't work because the
code treated byte values as fixed point.
- Fixed: LEVEL_NOALLIES must clear MF_FRIENDLY off any spawned actor except players.
Otherwise it doesn't work properly.
- Fixed: Entering a backslash in the player's name box caused a crash because
the code analyzing the string was missing a NULL pointer check.
- Fixed: Thing_Hate and Teleport_ZombieChanger unconditionally made state jumps,
even for dead monsters.
- Fixed: The palette flash for item pickup was not reset upon a player's death.
- Fixed: P_DamageMobj tried to get damage multiplier information from the
damage inflictor, not the attacker.
- Fixed: PowerTimeFreezer::DoEffect did not call its superclass method.
- fixed: When morphed monsters died they tried to set MF3_STAYMORPHED for the
attacker, not themselves. This caused a crash when they were killed by a crusher.
SVN r539 (trunk)
of scrunching the startup screen up to make room for it.
- Added the red net notches for Hexen's startup screen.
- Added hprintf and status simulation for Heretic's startup screen.
SVN r495 (trunk)
const char * with a string inside its buffer, it released the buffer
before copying the string.
- Added a new FString constructor that creates the string from a lump.
- Fixed: G_DoReborn() calls G_InitNew() with mapname set to level.mapname.
G_InitNew() then copies it onto level.mapname, which is undefined
behavior (although it does work as we want it to).
- Modified FMemLump to store its data using FString. That class provides
a convenient method of storing reference counted data, so now FMemLump
doesn't need to muck about sneakily using const_casts and possibly
tricking its users into thinking that an old one is still valid after
being assigned to a new one.
- Fixed: The IMGZ, PNG, PCX, and JPEG loaders assumed the files were
large enough for their headers without actually checking.
SVN r463 (trunk)
- Fixed: The screen wipe must be disabled for Heretic's underwater ending. If
not, the wipe will try to mix pictures with different palettes.
SVN r435 (trunk)
- Added more resolution options when playing windowed under SDL.
- Changed SDL mouse handling to be basically identical to the (non-DirectInput)
Win32 code. The mouse is polled periodically and constantly warped to the
center of the window. Despite what the SDL docs specify, SDL_WM_GrabInput()
is apparently no longer a reliable means of obtaining continuous relative
mouse motion events.
- Fixed: The non-Windows implementation of I_FindClose() did not check for -1
handles.
SVN r432 (trunk)
wadsrc/Makefile, nor did it use the makefile for cleaning.
- Added ST_NetMessage() for mixing miscellaneous messages with the network
startup meter, since they get mixed in the same space on the Linux terminal
and must be handled properly to avoid looking bad.
SVN r429 (trunk)
- Fixed: The host would let more than the desired number of players connect.
- Decreased the frequency of packets in ST_NetLoop() to two per second.
- Fixed: During the i_net handshaking, guests never verified that the messages
they received were from the host.
- Removed the -net command line option. I'm not sure it even worked anymore.
SVN r421 (trunk)
be surprised if it doesn't work.
- Reorganized the network startup loops so now they are event driven. There is
a single function that gets called to drive it, and it uses callbacks to
perform the different stages of the synchronization. This lets me have a nice,
responsive abort button instead of the previous unannounced hit-escape-to-
abort behavior, and I think the rearranged code is slightly easier to
understand too.
- Increased the number of bytes for version info during D_ArbitrateNetStart(),
in preparation for the day when NETGAMEVERSION requires more than one byte.
- I noticed an issue with Vista RC1 and the new fatal error setup. Even after
releasing a DirectDraw or Direct3D interface, the DWM can still use the
last image drawn using them when it composites the window. It doesn't always
do it but it does often enough that it is a real problem. At this point, I
don't know if it's a problem with the release version of Vista or not.
After messing around, I discovered the problem was caused by ~Win32Video()
hiding the window and then having it immediately shown soon after. The DWM
kept an image of the window to do the transition effect with, and then when
it didn't get a chance to do the transition, it didn't properly forget about
its saved image and kept plastering it on top of everything else
underneath.
- Added a network synchronization panel to the window during netgame startup.
- Fixed: PClass::CreateDerivedClass() must initialize StateList to NULL.
Otherwise, classic DECORATE definitions generate a big, fat crash.
- Resurrected the R_Init progress bar, now as a standard Windows control.
- Removed the sound failure dialog. The FMOD setup already defaulted to no
sound if initialization failed, so this only applies when snd_output is set
to "alternate" which now also falls back to no sound. In addition, it wasn't
working right, and I didn't feel like fixing it for the probably 0% of users
it affected.
- Fixed: The edit control used for logging output added text in reverse order
on Win9x.
- Went back to the roots and made graphics initialization one of the last
things to happen during setup. Now the startup text is visible again. More
importantly, the main window is no longer created invisible, which seems
to cause trouble with it not always appearing in the taskbar. The fatal
error dialog is now also embedded in the main window instead of being a
separate modal dialog, so you can play with the log window to see any
problems that might be reported there.
Rather than completely restoring the original startup order, I tried to
keep things as close to the way they were with early graphics startup. In
particular, V_Init() now creates a dummy screen so that things that need
screen dimensions can get them. It gets replaced by the real screen later
in I_InitGraphics(). Will need to check this under Linux to make sure it
didn't cause any problems there.
- Removed the following stubs that just called functions in Video:
- I_StartModeIterator()
- I_NextMode()
- I_DisplayType()
I_FullscreenChanged() was also removed, and a new fullscreen parameter
was added to IVideo::StartModeIterator(), since that's all it controlled.
- Renamed I_InitHardware() back to I_InitGraphics(), since that's all it's
initialized post-1.22.
SVN r416 (trunk)
- Made the Ettin's and Centaur's howling sound an actor property.
- Added A_CustomComboAttack function to finally have something that can
replace the old A_ComboAttack function.
- Added A_SpawnItemEx function that removes the problems with A_SpawnItem
and which also should make most of the A_CustomMissile abuse unnecessary.
- Added A_QueueCorpse to the list of DECORATE code pointers.
- Made the size of Hexen's corpse queue configurable by CVAR
(sv_corpsequeuesize.) Setting this CVAR to -1 will disable corpse
queuing completely so that even in Hexen all corpses will stay forever.
SVN r392 (trunk)
could not be saved for some reason.
- Added the writeini console command to write the config file, optionally
specifying a specific file name for it.
- Fixed: "Multiplayer" demos that only had one player were not played back
properly because the demo playback code only checked the number of players
to determine if it should be played as a netdemo.
