Prepping for using MMX and SSE intrinsics instead of inline assembly.
.. except for memcpy equivalents which only get faster if they can
exploit the parallelism of loading into multiple SIMD registers. :)
- SDL_Surface is a system memory representation of pixel data
- SDL_Texture is a video memory representation of pixel data
The concept of SDL_Surface with SDL_HWSURFACE is no longer used.
Separated SDL_Texture types by usage rather than memory type
- SDL_TEXTUREACCESS_STATIC is for rarely changed pixel data,
can be placed in video memory.
- SDL_TEXTUREACCESS_STREAMING is for frequently changing pixel
data, usually placed in system memory or AGP memory.
Optimized the SDL_compat usage of the OpenGL renderer by only
using one copy of the framebuffer instead of two.
I'm not entirely happy with them. Maybe the right way to go is to leave
SDL_iconv() taking a non-const inbuf? How often are we converting const
strings anyway?
On tracing it turns out to fail from SDL_WM_SetCaption()
On going through the function it looks like the SDL_free() function is called
every alternate time with an invalid pointer that has already been freed.
display, which is a fast path used for the whole-surface SDL 1.2 API.
Solved the flicker problems by implementing a backbuffer in the GDI renderer.
Unfortunately, now using the GDI renderer with a backbuffer and HBITMAPs is
significantly slower than SDL's surface code. *sigh*
Added DirectInput joystick code, contributed by Glenn Maynard.
This fixes a problem with the Windows Multimedia joystick driver
not showing all 6 axes on a GameCube controller converter, which
was donated by Jacob Kolding.
Currently there are two Classic-only drivers defined in "SDL_config_macos.h",
and the ones in "SDL_config_macosx.h" are Mach-O/framework-only (i.e. not CFM)
As a workaround, I disabled CDROM and JOYSTICK when building SDL for CFM
Carbon.
The current SVN trunk is missing the SDLCALL specifier at numerous locations.
It has to be added for all (possibly user provided) callbacks.
I stumbled over this while creating a makefile for the OpenWatcom compiler for
Win32.
- A change to define CXX in fatbuild, which comforts the configure script a little, even if we don't use C++ anywhere.
- Some code to see how many CPU cores exist and parallelize make across them.
- CFLAGS that apply to both archs are specified seperately (-O3, -pipe, etc)
- -fvisibility=hidden for the gcc4 builds
- a "clean", "clean-ppc" and "clean-x86" command
- Fix to SDL_config_macosx.h for the HAVE_ALLOCA_H thing.
Now builds on an Intel Mac.
The SDL platform header shouldn't dictate the OS target API for other
applications. The build system should define the target API for building
SDL internally.
[I'm fixing this for the public headers, but I'm not going to bother for the SDL library code (yet)]
To clarify: Normaly, GCC (or, to be precise, the preprocessor) will ignore
this, and compile the code happily. However, one can specify -Wundef to get a
warning about this.
One can probably argue whether to consider this a bug or not; but I think that
(a) from a semantic point of view, using "#if FOO" when FOO is not defined is
strange, and (b) since it is possible to trigger a warning about this, and a
trivial fix exists, it should be corrected.
I can think of two alternative patches, BTW:
1) Simply use #define HAVE_FOO 0, instead of not defining HAVE_FOO at all
2) Change
#if HAVE_FOO
to
#if HAVE_FOO+0
which always does the right thing.
But I think I still prefer the attached patch :-).
The proper name of Apple's operating system is "Mac OS X" not "MacOS X", as can
bee seen in many places, for example http://www.apple.com/macosx/). This
contrasts the naming of the old operating system, which was called "MacOS" and
today is often refered to as "MacOS Classic".
The attached patches fixes the misuse of the name "MacOS X" in both the SDL12
and sdlweb CVS modules.
The current definition of int32_t, uint32_t, uintptr_t
doesn't match what the Mac system headers already have...
Since it's an old 16/32 bit platform, the system headers
expect the types to use "long" and not "int" like they do.
When switching to "UNIX-style paths" as needed for the new includes,
including <GL/gl.h> and <GL/glu.h> doesn't work anymore on Mac OS...
The two headers are really located in the OpenGL SDK 1.2 CFM like this:
OpenGL:Headers:gl.h
OpenGL:Headers:glu.h
There are also some compat copies, that *used* to work with Mac paths:
OpenGL:Headers:GL/gl.h
OpenGL:Headers:GL/glu.h
The easiest fix is to make SDL_opengl.h include the proper header names,
by adding a special case for the MACOS platform in addition to the MACOSX
