From: Connor Abbott Date: Sat, 1 Jul 2017 02:10:43 +0000 (-0700) Subject: ac/nir: fix 64-bit shifts X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2ec77f7a3c95802cd54b015f613b044c0d135f72;p=mesa.git ac/nir: fix 64-bit shifts NIR always makes the shift amount 32 bits, but LLVM asserts if the two sources aren't the same type. Zero-extend the shift amount to make LLVM happy.
