From d1eea18a595a468dbc2267a8d14197a3b1a5a4b6 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Fri, 22 May 2015 16:40:08 -0400 Subject: [PATCH] nvc0/ir: set ftz when sources are floats, not just destinations In the case of a compare, the destination might be a predicate, but we still want to flush denorms.
