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++)
{
__builtin_tbegin (0);
dest = *src0 + src1;
__builtin_tend (0);
}
return dest;
}
If we compile it the same way:
foo:
cmpdi 0,6,0
blelr 0
mtctr 6
ld 3,0(4)
.p2align 4,,15
.L3:
tbegin. 0
tend. 0
bdnz .L3
add 3,3,5
blr
