From dd4b44efc04413453e4cbf78434b29392eb148a9 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Tue, 17 May 2016 03:27:02 -0400 Subject: nvc0/ir: fix shared atomic lowering to preserve shared memory location We were always doing atomics on shared memory location 0 instead of the originally supplied location. Make sure to pass through the original symbol and any indirection.
