[Qemu-devel] [PATCH 3/3] target-arm: Fix IL bit reported for Thumb VFP and Neon traps

[Peter Maydell <peter.maydell@linaro.org>]

All Thumb Neon and VFP instructions are 32 bits, so the IL
bit in the syndrome register should be set. Pass false to the
syn_* function's is_16bit argument rather than s->thumb
so we report the correct IL bit.
