a876ba55bd - Fixed: src/CMakeLists.txt did not pass -DNOASM to the compiler when assembly
is disabled.

ad96225213 - Changed Linux to use clock_gettime for profiling instead of rdtsc. This
avoids potential erroneous results on multicore and variable speed
  processors. Windows will need to be updated accordingly.

dda5ddd3c2 - Ported vlinetallasm4 to AMD64 assembly. Even with the increased number of
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.

b695330e90 - Removed FourthWeaponClass and based Hexen's fourth weapons on the generic weapon
pieces.
- Added DECORATE conversions for Hexen's Fighter weapons by Karate Chris.
- Added aWeaponGiver class to generalize the standing AssaultGun.
- converted a_Strifeweapons.cpp to DECORATE, except for the Sigil.

efb8ffc459 - The x87 precision control is now explicitly set for double precision, since
GCC defaults to extended precision instead, unlike Visual C++.
- Removed the useless src/Linux directory from the repository. This was a
  holdover from the long-gone 1.22 build system.

ff2680baa9 - Removed new warning when using CMake 2.6.
- Fixed compilation of snes_spc on GCC <4.3.
- Fixed compilation of zstring.h on 32-bit MinGW, where SIZE_MAX
  and UINT_MAX are not considered identical by the preprocessor.

2ce3e1dd6a - Corrected the revision_check target so that it always checks the revision,
not just when src/svnrevision.h is not present.

de5d4715c2 - Added Linux support for the CMakeLists. This meant downgrading them for
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.

fb50df2c63 About a week's worth of changes here. As a heads-up, I wouldn't be
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.
