Ronald S. Bultje 6af2801088 swscale: split swscale.c in unscaled and generic conversion routines. 
This duplicates the function fillPlane().

Ronald S. Bultje 2762ee3034 swscale: cosmetics. 
Remove duplicate "inC" and "_c" functions that do the same thing;
give each function that handles data and acts as a function pointer
a "_c" suffix; remove "_c" suffix from functions that are inherently
not optimizable. Remove inline keyword from functions that are only
used through function pointers.

Ronald S. Bultje 0d793db1b0 swscale: remove unused COMPILE_TEMPLATE_ALTIVEC. 2011-06-02 21:29:59 -07:00
Ronald S. Bultje 808d8ff6bb swscale: allocate larger buffer to handle altivec overreads. 
Altivec sws code intentionally overreads buffers for better performance,
so we need to allocate larger buffers to handle that.

Ronald S. Bultje 389e2000eb swscale: delay allocation of formatConvBuffer(). 
That means it won't be allocated when not needed. Alongside
this, it fixes valgrind/fate-detected memory leaks.

Ronald S. Bultje b4a224c5e4 swscale: split chroma buffers into separate U/V planes. 
Preparatory step to implement support for sizes > VOFW.
 2011-05-26 09:31:27 -04:00
Ronald S. Bultje 69645c021a swscale: replace formatConvBuffer[VOF] by allocated array. 
This allows to convert between formats of arbitrary width,
regardless of the value of VOF/VOFW.

Ronald S. Bultje 522d65ba25 rgb2rgb: remove duplicate mmx/mmx2/3dnow/sse2 functions. 
Many functions have such a prefix, but do not actually use any
instructions or features from that set, thus giving the false
impression that swscale is highly optimized for a particular
system, whereas in reality it is not.

Ronald S. Bultje 836b82e3c9 swscale: reindent h[cy]scale_fast() and updateDitherTables(). 2011-05-26 09:31:02 -04:00
Ronald S. Bultje e2bad983b5 swscale: reformat x86/swscale_template.c. 
Interleave macros and code so that it's easier to find the
actual code that belongs to a function. Also reindent where
appropriate and remove dead code.

Ronald S. Bultje 71d9c33c86 swscale: remove duplicate mmx/mmx2 functions if they are identical. 2011-05-26 09:30:15 -04:00
Ronald S. Bultje acb96bc268 swscale: remove if (c->dstFormat) branch from yuv2packed[12X](). 
This allows cutting up the function in much smaller and easier-
to-maintain chunks.
 2011-05-26 09:30:14 -04:00
Ronald S. Bultje b6cac9b3bf swscale: remove if(full_chr_int) from yuv2packed1(). 
If that flag is set, swScale() already proxies the call to
yuv2rgbXinC_full(). Therefore, this flag is never set when
yuv2packed1() is called.

Ronald S. Bultje 1bb0f0c925 swscale: remove if(bitexact) branch from functions. 
Instead, only set the function pointers if bitexact flag is
not set during initialization. Since a change in flags triggers
a re-init anyway, this doesn't situations where flag values
change during runtime.
 2011-05-24 14:50:20 -04:00
Ronald S. Bultje 566b5fbbb3 swscale: remove if(canMMX2BeUsed) conditional. 
Instead, set function pointers conditionally during init. This
patch also reveals a whole branch of dead assembly code that is
therefore also removed.

Ronald S. Bultje 1dd4f4be5a swscale: remove AMD3DNOW "optimizations". 
The functions are identical to their MMX counterparts. Thus,
pretending that swscale is highly optimized for AMD3DNOW
extensions is a poorly executed practical joke at best.

Ronald S. Bultje 76f8a96e00 [PATCH] Update pixdesc_be fate refs after adding 9/10bit YUV420P formats. 
Also remove code that overwrites the C versions of functions in
sws_init_swScale_altivec(), so that it uses the C functions of files
if no altivec-optimized version exists.
