* x86inc: Drop SECTION_TEXT macroHenrik Gramner2015-08-04
| | | | | The .text section is already 16-byte aligned by default on all supported platforms so `SECTION_TEXT` isn't any different from `SECTION .text`.
* avcodec/x86: add missing colon to labelsJames Almer2015-07-26
| | | | | | Silences warnings with Nasm Signed-off-by: James Almer <jamrial@gmail.com>
* x86: hevc_mc: fewer xmm regs used in epel h/vChristophe Gisquet2015-02-17
| | | | | | | 11 xmm regs seem only required for avx2. Reviewed-by: Mickaël Raulet <mraulet@insa-rennes.fr Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* x86: hevc_mc: save 1 gpr in epel filter loadingChristophe Gisquet2015-02-16
| | | | | | | The 3*stride value stored in r3src can be loaded much later, so use r3src instead of a dedicated gpr when possible. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* x86: hevc: remove a parameter to WP internalsChristophe Gisquet2015-02-14
| | | | | | | The second stride is always the internal buffer one, MAX_PB_SIZE (times 2 to get the value in bytes). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | The second parameter to the macro is always an immediate address, so no lea is needed. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* x86: hevc_mc: fewer gpr autoloads for _v filtersChristophe Gisquet2015-02-08
| | | | | | In that case, it's just to load my, but mx/r3src is not used. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | The width parameter is now completely at the back, and actually never used. This helps understanding the actual parameter list. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* x86: hevc_mc: better register allocationChristophe Gisquet2014-05-28
| | | | | | | | | | | | | | | | | | | | | The xmm reg count was incorrect, and manual loading of the gprs furthermore allows to noticeable reduce the number needed. The modified functions are used in weighted prediction, so only a few samples like WP_* exhibit a change.
