[webkit-dev] Data Memory Barrier ARMv6 question

Hi all.

I'm working in this patch
(https://bugs.webkit.org/show_bug.cgi?id=172767) and Mark Lam raised
some questions about the data memory barrier (DMB for short) in ARMv6
using "mcr 15 ...". The point is that we are having divergences in ARM
official reference manual about the semantics of this instruction. We
have it discussed in the bug above and I would like to know if there
is somebody with stronger ARM background that could help us there and
then approve the patch to be committed.

I thanks in advance and best regards,
Caio Lima.
