From 8b26a2d96d5806d698f827d5521cf75504dc3a85 Mon Sep 17 00:00:00 2001 From: Jose Maria Casanova Crespo Date: Sat, 9 Jun 2018 11:45:57 +0200 Subject: [PATCH] intel/fs: shuffle_from_32bit_read for 64-bit do_untyped_vector_read do_untyped_vector_read is used at load_ssbo and load_shared. The previous MOVs are removed because shuffle_from_32bit_read can handle storing the shuffle results in the expected destination just using the proper offset.
