From 46417784d21c89446763f2047228977bdc267895 Mon Sep 17 00:00:00 2001 From: Andrew Jones Date: Fri, 2 Aug 2019 14:25:31 +0200 Subject: [PATCH] target/arm/cpu: Use div-round-up to determine predicate register array size Unless we're guaranteed to always increase ARM_MAX_VQ by a multiple of four, then we should use DIV_ROUND_UP to ensure we get an appropriate array size.
