I looked at code of atomic_cas32() and it uses the legacy built-in
__sync_val_compare_and_swap().
Can it be that that built-in isn't supported on ARM?
Is there a newer built-in which should be used?
It could be. Can you test if __atomic_compare_exchange avoids the TSAN
error?
inline boost::uint32_t atomic_cas32
( volatile boost::uint32_t *mem
, boost::uint32_t with, boost::uint32_t cmp)
{
__atomic_compare_exchange
(const_cast<boost::uint32_t*>(mem), &cmp, &with, false
,__ATOMIC_SEQ_CST, __ATOMIC_SEQ_CST);
return cmp;
}
I changed the code as you suggested, but I still get the same error.
Cheers,
Jens
Sorry to hear that. I'm afraid I've run out of ideas :-(
