Subject: [FFmpeg-devel] [PATCH 2/2] swscale: Fix AltiVec/VSX build with
|
||
|
recent GCC

The argument to vec_splat_u16 must be a literal. By making the
|
||
|
function always inline and marking the arguments const, gcc can
|
||
|
turn those into literals, and avoid build errors like:
|
||
|
|
||
|
swscale_vsx.c:165:53: error: argument 1 must be a 5-bit signed literal
