Subject: [FFmpeg-devel] [PATCH 2/2] swscale: Fix AltiVec/VSX build with
recent GCC
In-Reply-To: <20190806155537.25535-1-daniel@octaforge.org>
References: <20190806155537.25535-1-daniel@octaforge.org>
Message-ID: <20190806155537.25535-3-daniel@octaforge.org>
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
