ARM: VP8: fix build on systems with global symbol prefix

Signed-off-by: Mans Rullgard <>
(cherry picked from commit 0b32da90f893b3e04ead18a546252e241a6a0988)

cf9c227e 02/27/2011 11:34 PM Mans Rullgard

ARM: fix vp8 neon with pic enabled

The assembler emits literal pools too far from the load instructions,
so we must do it explicitly at a suitable location.

Signed-off-by: Mans Rullgard <>
(cherry picked from commit 8b454c352f49c2a61db37793d838b553db3da734)

11ab1e40 02/14/2011 10:58 PM Loren Merritt

FFT: factor a shuffle out of the inner loop and merge it into fft_permute.

6% faster SSE FFT on Conroe, 2.5% on Penryn.

Signed-off-by: Janne Grunau <>
(cherry picked from commit e6b1ed693ae4098e6b9eabf938fc31ec0b09b120)

4ae3ee4a 02/12/2011 11:52 PM Mans Rullgard

VP8: ARM optimised decode_block_coeffs_internal

Approximately 5% faster on Cortex-A8.

Signed-off-by: Mans Rullgard <>
(cherry picked from commit a7878c9f73c12cfa685bd8af8f3afcca85f56a8b)

5da7494d 02/12/2011 11:52 PM Mans Rullgard

ARM optimised vp56_rac_get_prob()

Approximately 3% faster on Cortex-A8.

Signed-off-by: Mans Rullgard <>
(cherry picked from commit 7da48fd0111adf504cfcfc5ebda7fd0681968041)

ef15d71c 02/09/2011 02:31 AM Mans Rullgard

VP8: ARM NEON optimisations for dsp functions

This adds NEON optimised versions of all functions in VP8DSPContext.
Based on initial work by Rob Clark.

Signed-off-by: Mans Rullgard <>
(cherry picked from commit a1c1d3c003b0ec16fdb6574913781313fb2c7ab6)

01b75fa9 02/04/2011 02:08 AM Mans Rullgard

ARM: add helper macro for declaring constant data

Signed-off-by: Mans Rullgard <>
(cherry picked from commit b9a639ddd6e102edbf94a26b5106386792e2e4c8)

fe2ff6d2 02/04/2011 02:08 AM Justin Ruggles

Separate format conversion DSP functions from DSPContext.

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

Signed-off-by: Mans Rullgard <>
(cherry picked from commit c73d99e672329c8f2df290736ffc474c360ac4ae)

a8ae4e0e 02/02/2011 02:40 AM Justin Ruggles

Remove unneeded add bias from 3 functions.

DSPContext.vector_fmul_window()
DCADSPContext.lfe_fir()
SynthFilterContext.synth_filter_float()

Signed-off-by: Mans Rullgard <>
(cherry picked from commit 80ba1ddb58b5923b9f36a6acd542affc4ca722eb)

451b4b86 01/30/2011 02:41 AM Mans Rullgard

Rearrange MpegEncContext to simplify access from asm

This moves the fields needed by asm near the top, before any
structs or other members which complicate the offset calculation.
Modifying other structs will no longer require updating the offsets,
and the asm code is slightly simpler due to the smaller offsets....
