[Mesa-dev] [PATCH] r600g: don't change the order of writes in merge_inst_group

Merge may produce incorrect order of operations for r600-eg: x: inst1 R0.x, ... ; //from current group ... t: inst0 R0.x, ... ; //from previous group, same destination Result of inst1 will be lost. So compare destinations and don't allow this. Signed-off-by: Vadim Girl
