2015-05-28avutil/mips: Restructure of generic macrosShivraj Patil
This patch includes restructuring of existing macros and addition of more generic macros. This change was necessary to avoid repeated review comments in remaining patches which we were about to submit. Also this patch reduces number of code lines due to maximum use of generic macros, allows better code alignment & readability etc. These modifications in commonly used .libavutil/mips/generic_macros_msa.h. impacts the already accepted code, hence re-submitting it in 2/4,3/4 & 4/4. Overall, this patch set is just upgrading the code with styling changes and will bring it in sync with MIPS-SIMD optimized latest codebase at our end.

2015-05-28x86inc: Clear __SECT__Timothy Gu
This commit silences warning(s) like: libavcodec/x86/fft.asm:93: warning: section flags ignored on section redeclaration The cause of this warning is that because `struc` and `endstruc` attempts to revert to the previous section state [1]. The section state is stored in the macro __SECT__, defined by x86inc.asm to be `.note.GNU-stack ...`, through the `SECTION` directive [2]. Thus, the `.note.GNU-stack` section is defined twice (once in x86inc.asm, once during `endstruc`), causing the warning. That is the first part of the commit: using the primitive `[section]` format for .note.GNU-stack etc., which does not update `__SECT__` [2]. That fixes only half of the problem. Even without any `SECTION` directives, `__SECT__` is predefined as `.text`, which conflicting with the later `SECTION_TEXT` (which expands to `.text align=16`).

2015-05-14libavutil/softfloat: Add test case for av_add_sfNedeljko Babic
Recently normalization (av_normalize_sf) of output was added to av_add_sf. This normalization is used for better precision for small values and the purpose of this (quite simple) test case is to test difference between double and softfloat. The values used are tailored to maximally highlighte problem with precison when normalization is not used.

2015-05-13imgutils: initialize palette padding bytes in av_image_allocAndreas Cadhalpun
av_image_fill_pointers always aligns the palette, but the padding bytes don't (and can't) get initialized in av_image_copy. Thus initialize them in av_image_alloc. This fixes 'Syscall param write(buf) points to uninitialised byte(s)' valgrind warnings.
