2012-06-11Fix pedantic compiler warningsJohn Koleszar
Allows building the library with the gcc -pedantic option, for improved portabilty. In particular, this commit removes usage of C99/C++ style single-line comments and dynamic struct initializers. This is a continuation of the work done in commit 97b766a46, which removed most of these warnings for decode only builds. Change-Id: Id453d9c1d9f44cc0381b10c3869fabb0184d5966

2012-01-30New RTCD implementationJohn Koleszar
This is a proof of concept RTCD implementation to replace the current system of nested includes, prototypes, INVOKE macros, etc. Currently only the decoder specific functions are implemented in the new system. Additional functions will be added in subsequent commits. Overview: RTCD "functions" are implemented as either a global function pointer or a macro (when only one eligible specialization available). Functions which have RTCD specializations are listed using a simple DSL identifying the function's base name, its prototype, and the architecture extensions that specializations are available for. Advantages over the old system: - No INVOKE macros. A call to an RTCD function looks like an ordinary function call. - No need to pass vtables around. - If there is only one eligible function to call, the function is called directly, rather than indirecting through a function pointer. - Supports the notion of "required" extensions, so in combination with the above, on x86_64 if the best function available is sse2 or lower it will be called directly, since all x86_64 platforms implement sse2. - Elides all references to functions which will never be called, which could reduce binary size. For example if sse2 is required and there are both mmx and sse2 implementations of a certain function, the code will have no link time references to the mmx code. - Significantly easier to add a new function, just one file to edit. Disadvantages: - Requires global writable data (though this is not a new requirement) - 1 new generated source file. Change-Id: Iae6edab65315f79c168485c96872641c5aa09d55

2012-01-20Disconnect ARM tgt_isa from dsp extensionsFritz Koenig
A processor with ARMv7 instructions does not necessarily have NEON dsp extensions. This CL has the added side effect of allowing the ability to enable/disable the dsp extensions cleanly. Change-Id: Ie1e879b8fe131885bc3d4138a0acc9ffe73a36df
2012-01-06Reduced the size of Y1Dequant and friends to [128][2]Scott LaVarnway
This patch removes the local copies of the dequantize constants and implements John's idea as described in "Make a local copy of the dequantized data" commit. Change-Id: Ic6b7d681f00bf63263f71ff1e39ab2f80729e8b2
2011-12-21Remove useless g_common.hJohn Koleszar
This file declared a bunch of nonexistent, unreferenced global function pointers. Change-Id: Ic26bb8c7712deba754c49fc01f383b53afc9e728
2011-12-15Moved dequant idct into commonScott LaVarnway
These functions are now used by the encoder. This is WIP with the goal of creating a common idct/add for the encoder and decoder. A boost of 1.8% was seen for the HD rt test clip used. [Tero] Added needed changes to ARM side. Change-Id: Ibbb8000be09034203d7adffc457d3c3f8b06a5bf
2011-11-25Modified the inverse walsh to output directlyScott LaVarnway
to the dqcoeff or qcoeff buffer. The encoder would populate the dc coeffs of the y blocks as a separate stage (recon_dcblock) and the decoder would use a special version of the idct. This change eliminates the extra copy and reduces the code footprint. [Tero] Added needed changes to armv6 and NEON assembly. Change-Id: I83202ffdbaf83f6e5dd69f4ba2519fcf0b13b3ba
2011-11-09ARMv6 optimized Intra4x4 predictionTero Rintaluoma
Added ARM optimized intra 4x4 prediction - 2x faster on Profiler compared to C-code compiled with -O3 - Function interface changed a little to improve BLOCKD structure access Change-Id: I9bc2b723155943fe0cf03dd9ca5f1760f7a81f54
2011-10-18Remove usage of predict buffer for decodeScott LaVarnway
Instead of using the predict buffer, the decoder now writes the predictor into the recon buffer. For blocks with eob=0, unnecessary idcts can be eliminated. This gave a performance boost of ~1.8% for the HD clips used. Tero: Added needed changes to ARM side and scheduled some assembly code to prevent interlocks. Patch Set 6: Merged (I1bcdca7a95aacc3a181b9faa6b10e3a71ee24df3) into this commit because of similarities in the idct functions. Patch Set 7: EC bug fix.

2011-06-28Merge "Avoid text relocations in ARM vp8 decoder"Johann
2011-06-28Avoid text relocations in ARM vp8 decoderMike Hommey
The current code stores pointers to coefficient tables and loads them to access the tables contents. As these pointers are stored in the code sections, it means we end up with text relocations. eu-findtextrel will thus complain about code not compiled with -fpic/-fPIC. Since the pointers are stored in the code sections, we can actually cheat and let the assembler generate relative addressing when accessing the coefficient tables, and just load their location with adr.

the decision to run the regular or simple loopfilter is made outside the function and managed with pointers stop tracking the option in two places. use filter_type exclusively Change-Id: I39d7b5d1352885efc632c0a94aaf56b72cc2fe15
2011-03-11Move build_intra_predictors_mby to RTCD frameworkJohn Koleszar
The vp8_build_intra_predictors_mby and vp8_build_intra_predictors_mby_s functions had global function pointers rather than using the RTCD framework. This can show up as a potential data race with tools such as helgrind. See https://bugzilla.mozilla.org/show_bug.cgi?id=640935 for an example. Change-Id: I29c407f828ac2bddfc039f852f138de5de888534
