qemu-arm does not reject vrintz on non-v8 cpu
Status in QEMU:
It seems that qemu-arm does not reject some v8-only instructions as it
should, but executes them "correctly".
For instance, while compiling/running some of the GCC ARM instrinsics tests,
we noticed that
vrintz should be rejected on cortex-a9 for instance, while it is executed as
if the instruction was supported.
1074c: f3fa05a0 vrintz.f32 d16, d16
and qemu -d in_asm says:
0x0001074c: f3fa05a0 vabal.u<illegal width 64> q8, d26, d16
The problem is still present in qemu-2.6.0
