On Valhall, we can end up with a lot of convertions for 8-bit and 16-bit values. However, since Valhall, we have access to a lot more swizzles on widen sources. The idea of this pass is to propagate replicate swizzle usages to simplify things. We do not attempt to propagate MKVEC.v2i16 as it is already handled by bi_lower_swizzle. This changes the following: 9 = V2S8_TO_V2S16 !7.b0 11 = IADD.v2s16 !9.h00, u4 88 = MKVEC.v2i8 11.b0, u256.b0, u256 13 = IMUL.v4i8 !88.b0, 8.b0 14 = V2S8_TO_V2S16 !13.b0 15 = IADD.v2s16 14.h00, !11.h00 89 = MKVEC.v2i8 !15.b0, u256.b0, u256 17 = IMUL.v4i8 !89.b0, !8.b0 Into this: 11 = IADD.v2s16 !7.b0, u4 13 = IMUL.v4i8 11.b0, 8.b0 15 = IADD.v2s16 13.b0, !11.h00 17 = IMUL.v4i8 !15.b0, !8.b0 Signed-off-by: Mary Guillemard <mary.guillemard@collabora.com> Reviewed-by: Olivia Lee <olivia.lee@collabora.com> Reviewed-by: Christoph Pillmayer <christoph.pillmayer@arm.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/37167>
