Frank Barchard fd3e676e91 android_full_debug x86 fix - use +rm for width count
Work around for android full debug build runnign out of registers.
5 functions were running out of registers causing the compiler error
error: 'asm' operand has impossible constraints
These functions mostly have 4 pointers, a counter (width) and a tempory
eax register.  With fpic and debug using stackframes, 2 registers are
unavailable.  So a total of 8 registers are used.
Although fpic and stack frame dont apply to assembly, the compiler
reserves 2 registers.  The optimized version builds, so its likely
freeing up the registers once it knows they are not used.
These functions used to build, so compile options and/or compiler may
have updated.. likely fpic was turned on.
An attribute can be done to disable each, and will avoid using the
2 GPR registers, but they are still reserved and unavailable in debug
builds on current compilers (gcc 4.9 and clang 3.8).

libyuv android_full_debug x86 fix - use +rm for width count 2016-06-14 15:25:28 -07:00
libyuv.h Remove bayer format support from libyuv. This format is very rare and used on legacy hardware. Its not well optimized and has bugs related to odd widths. Removing the format will allow tests to pass under more circumstances, run faster and allow focus on higher priority quality and performance issues. 2015-02-09 19:58:19 +00:00
