[PULL 14/15] target/arm: Return correct IL bit in merge_syn_data_abort

From: Peter Maydell
Subject: [PULL 14/15] target/arm: Return correct IL bit in merge_syn_data_abort
Date: Fri, 17 Jan 2020 14:28:15 +0000

From: Jeff Kubascik <address@hidden>

The IL bit is set for 32-bit instructions, thus passing false
with the is_16bit parameter to syn_data_abort_with_iss() makes
a syn mask that always has the IL bit set.

Pass is_16bit as true to make the initial syn mask have IL=0,
so that the final IL value comes from or'ing template_syn.
