Tested with GCC 7.2.1 on powerpc64le.
The copy of vs36 (v4) to vs32 (v0) shouldn't be required, i.e. I'd expect to
have xsmaddqp v4,v2,v3.

Depending on the level of optimization, GCC moves a memory access outside a
transaction which breaks the atomicity of the transaction

(In reply to Andrew Pinski from comment #3)
Since there are no stores, the load seems like it can be pulled out of the
loop too.
I disagree with you

Oooops. My bad.
What about this one?
$ cat tbegin-barrier.c
long
foo (long dest, long *src0, long src1, long tries)
{
long i;
for (i = 0; i tries; i
