Looking through code I noticed that in target/arm/translate.c there
is the following comment in the decode for the load-acquire/store-release
instructions:
/* Since the emulation does not have barriers,
the acquire/release semantics need no special
handling */
This is out of date now we have MTTCG, isn't it?
The equivalent code in translate-a64.c has some calls to tcg_gen_mb()
to emit barriers...presumably we need to fix the a32 code to do
the same.
(We haven't noticed this because I think in practice nobody
much is compiling Armv8-specific AArch32 code.)
