Ticket #13914 – Description
initial v1 1 1 G5 based computers see a significant performance boost in x264 if the compiler is told to build specifically for it. I've created a simple variant for the G5. 2 2 3 {{{ 3 4 variant G5 { 4 5 configure.cflags-append "-mcpu=970 -mtune=970 -mpowerpc64 -mpowerpc-gpopt -fast -mabi=altivec -maltivec" 5 6 } 7 }}} 6 8 7 9 Most of the improvements come from the first four parameters. You could argue that -fast isn't really a G5 specific tag, so it shouldn't be here, but since this is trying to tune as tightly for performance, I think it is worth having. I can make a patch file if it is needed.
