I tested this patch in v1.6 and v1.7 on my Pi, and it seems to work
just fine. "make check" passes all the ASM tests.
Just to be perfectly clear: it wouldn't on ARMv5 though, and the ARMv6
ASM test executed with NOPs for barriers, although it would correctly
pass all other tests.
Mmm. Ok. So is this a correct list of what is supported right now (i.e., in
v1.6 with your patch)

ARM4: no
ARM5: no
ARM6: sorta (not multi-core, or anywhere we would need barriers)
ARM7: yes
?
Correct, that is what is supported with out-of-line assembler functions
- i.e. when explicitly building with -DOMPI_DISABLE_INLINE_ASM.
They are all supported (and correctly using barriers) otherwise.
How would George's patch have changed that list?
ARM4: no
ARM5: maybe, unvalidated
ARM6: yes
ARM7: yes
