2014-04-29Remove VP8 save_reg_neon functionYunqing Wang
This patch did a cleanup following the commit "Save NEON registers in VP8 NEON functions". The pushing/poping of callee-saved NEON registers was moved into individual NEON functions. Therefore, we don't need to save those registers at the beginning of codec. The related code was removed. Change-Id: I5648166514fc9beffb780aa138495597731f49ea
2014-04-28Save NEON registers in VP8 NEON functionsYunqing Wang
The recent compiler can generate optimized code that uses NEON registers for various operations besides floating-point operations. Therefore, only saving callee-saved registers d8 - d15 at the beginning of the encoder/decoder is not enough anymore. This patch added register saving code in VP8 NEON functions that use those registers. Change-Id: Ie9e44f5188cf410990c8aaaac68faceee9dffd31

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
2012-05-02Fix TEXTRELs in the ARM asm.Timothy B. Terriberry
Besides imposing a performance penalty at startup in most configurations, these relocations break the dynamic linker for native Fennec, since it does not support them at all. Change-Id: Id5dc768609354ebb4379966eb61a7313e6fd18de

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

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
2011-10-18Remove 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.

2011-06-28Avoid 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.

2011-01-28Adds "armvX-none-rvct" targetsTero Rintaluoma
Adds following targets to configure script to support RVCT compilation without operating system support (for Profiler or bare metal images). - armv5te-none-rvct - armv6-none-rvct - armv7-none-rvct To strip OS specific parts from the code "os_support"-config was added to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS specific parts such as OS specific includes and function calls for timers and threads etc. This was done to enable RVCT compilation for profiling purposes or running the image on bare metal target with Lauterbach. Removed separate AREA directives for READONLY data in armv6 and neon assembly files to fix the RVCT compilation. Otherwise "ldr <reg>, =label" syntax would have been needed to prevent linker errors. This syntax is not supported by older gnu assemblers. Change-Id: I14f4c68529e8c27397502fbc3010a54e505ddb43
2010-10-27Eliminate more warnings.Timothy B. Terriberry
This eliminates a large set of warnings exposed by the Mozilla build system (Use of C++ comments in ISO C90 source, commas at the end of enum lists, a couple incomplete initializers, and signed/unsigned comparisons). It also eliminates many (but not all) of the warnings expose by newer GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite without checking the return values). There are a few spurious warnings left on my system: ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used uninitialized in this function gcc seems to be unable to figure out that the value shortcut doesn't change between the two if blocks that test it here. ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned expression >= 0 is always true ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned expression >= 0 is always true This is true, so far as it goes, but it's comparing against an enum, and the C standard does not mandate that enums be unsigned, so the checks can't be removed.

2010-10-26make vp8_recon16x16mb{,y} RTCD functionsJohn Koleszar
ARM NEON has a platform specific version of vp8_recon16x16mb, though it's just a stub to extract the various parameters from the MACROBLOCKD struct and pass them to vp8_recon16x16mb_neon(). Using that function's prototype directly will be a better long term solution, but it's quite an invasive change. Change-Id: I04273149e2ade34749e2d09e7edb0c396e1dd620
2010-10-25reuse common loopfilter codeJohann
there were four versions for the regular and macroblock loopfilters: horizontal [y|uv] vertical [y|uv] this moves all the common code into 2 functions: vp8_loop_filter_neon vp8_mbloop_filter_neon this provides no gain in performance. there's a bit of jitter, but it trends down ~0.25-0.5%. however, this is a huge gain maintenance. also, there is the potential to drop some stack usage in the macroblock loopfilter. Change-Id: I91506f07d2f449631ff67ad6f1b3f3be63b81a92
2010-09-30Fix valgrind errors in the NEON loop filters.Timothy B. Terriberry
Like the ARMv6 code, these functions were accessing values below the stack pointer, which can be corrupted by signal delivery at any time.
2010-09-24combine max values and compare onceJohann
previous implementation compared each set of values to limit and then &'d them together, requiring a compare and & for each value. this does the accumulation first, requiring only one compare Change-Id: Ia5e3a1a50e47699c88470b8c41964f92a0dc1323

2010-07-26update arm idct functionsJohann
Jeff Muizelaar posted some changes to the idct/reconstruction c code. This is the equivalent update for the arm assembly. This shows a good boost on v6, and a minor boost on neon.
