files. During aosp builds with binutils-2.27, we're seeing linker error messages of this form: libvpx.a(subpixel_mmx.o): relocation R_386_GOTOFF against preemptible symbol vp8_bilinear_filters_x86_8 cannot be used when making a shared object subpixel_mmx.o is assembled from "vp8/common/x86/subpixel_mmx.asm". Other messages refer to symbol references from deblock_sse2.o and subpixel_sse2.o, also assembled from asm files. This change marks such symbols as having "protected" visibility. This satisfies the linker as the symbols are not preemptible from outside the shared library now, which I think is the original intent anyway. Change-Id: I2817f7a5f43041533d65ebf41aefd63f8581a452

The neon intrinsics are not able to load just the 4 values that are used. In vpx_dsp/arm/intrapred_neon.c:dc_4x4 it loads 8 values for both the 'above' and 'left' computations, but only uses the sum of the first 4 values. BUG=webm:1268 Change-Id: I937113d7e3a21e25bebde3593de0446bf6b0115a

2016-05-27vpx_ports/mem_ops.h: cast the lhs of bitwise shifts of 24.Tom Finegan
C does not allow for shifting into the sign bit of a signed integer, and the two instances here become signed ints via promotion. Explcitly cast them to unsigned MEM_VALUE_T to avoid the problem.

2015-05-27Don't #define snprintf in VS 2015 or higher.Johann
In VS 2015 and higher snprintf is supplied and therefore vsnprintf doesn't need to be defined. This also avoids problems caused by _snprintf being different from snprintf. This fixes a build break with VS 2015 and improves security. Originally submitted via chromium by brucedawson@chromium.org https://codereview.chromium.org/1055603003 Additionally break this MSVC-specific tweak to a new file, which will become the home of all such MSVC-specific things. This requires adding a dependency on msvc.h to every example which uses args.c and tools_common.h Change-Id: I35b5f8e7ea00f6627403aabc9ea79b0412557a99

2015-05-07replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNEDJames Zern
this macro was used inconsistently and only differs in behavior from DECLARE_ALIGNED when an alignment attribute is unavailable. this macro is used with calls to assembly, while generic c-code doesn't rely on it, so in a c-only build without an alignment attribute the code will function as expected.

2014-11-06Remove asm offset dependenciesJohann
The obj_int_extract code is no longer worth maintaining. It creates significant issues when adapting for different build systems and no longer offers as significant of a performance benefit due to improvements in intrinsics. Source files will remain until the various third-party builds are updated. The neon fast quantizer has been moved to intrinsics. The armv6 version has been removed because so few remaining targets require it. Compilers and processors have improved significantly since the pack_tokens code was written. The assembly is no longer faster than the C code. pack_tokens were the only optimizations for the armv5te targets so the targets will be removed after the test infrastructure has been updated.
