From 728d7bc85f1f101875349690bf1637037a5a1817 Mon Sep 17 00:00:00 2001 From: Neil Roberts Date: Mon, 5 Oct 2015 13:50:56 +0200 Subject: [PATCH] i965: Add a second successor to BRW_OPCODE_WHILE It is possible to directly predicate the WHILE instruction. In this case there will be a second successor block because the execution can resume from the instruction after the loop. This will be used in a subsequent patch.
