From 0ef8c5cb96f6b1fea7c18c25fbff2adb6d7d0736 Mon Sep 17 00:00:00 2001 From: Connor Abbott Date: Fri, 30 Oct 2015 18:19:34 -0400 Subject: [PATCH] i965/sched: don't calculate live intervals for post-RA scheduling For some reason, this causes assertions on gm965 only. In any case, it's unnecessary since we don't need liveness information in the post-RA scheduler.
