* Hide global symbols for macho32/64m31-baselineYunqing Wang2013-10-301-0/+4
| | | | | | | Added hiding global symbols for macho32 and macho64 in x86inc.asm. This was done to fix exported symbol issue in Chrome build. Change-Id: I08d5c559b985b82f655b537469fee125615e78c0

* changed to comply with strict aliasing ruleYaowu Xu2013-10-291-2/+2
| | | | | | | | | The clamp operation may not affect the values of the final assigned mv where compiler may make use of strict aliasing rule to optimize out the clamp operation. This change made the code segments to better comply the strict aliasing rule. Change-Id: I24502ff18bd4f9e62507a879cc8760a91a0fd07e

* Remove redundant mode update in sub8x8 decodingJingning Han2013-10-281-2/+3
| | | | | | | | | | | | | | The probability model used to code prediction mode is conditioned on the immediate above and left 8x8 blocks' prediction modes. When the above/left block is coded in sub8x8 mode, we use the prediction mode of the bottom-right sub8x8 block as the reference to generate the context. This commit moves the update of mbmi.mode out of the sub8x8 decoding loop, hence removing redundant update steps and keeping the bottom- right block's mode for the decoding process of next blocks.

| * Fix x86inc.asm to build PIC code correctlyYunqing Wang2013-09-183-35/+137
| | | | | | | | | | | | | | | | | | | | | | | | Current x86inc.asm didn't handle 32bit PIC build properly. TEXTRELs were seen in the library built. The PIC macros from libvpx's x86_abi_support.asm was used to fix this problem. The assembly code was modified to use the macros. Notes: We need this fix in for decoder building. Functions in encoder will be fixed later. Change-Id: Ifa548d37b1d0bc7d0528db75009cc18cd5eb1838

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jenkins was failing to detect the case where an existing file is recreated with new content. In this case, thinking that the file already existed, Jenkins did not re-copy the file as it should have. By adding the file test-data.sha1 as a dependendency to the LIBVPX_TEST_DATA build target the files will be recopied if the MD5 of an existing file changes. This could be further improved to only copy files that have changed rather than copying the whole set as done in this patch. (Thanks to jzern@ who diagnozed ithe problem and suggested this fix).
