[Bug c++/37631] non-volatile asm passes volatile asm (-O3)

------- Comment #2 from pardo at google dot com  2008-09-29 17:48 -------
How can I prevent relative motion?  I tried adding a "memory" constraint to all
asms, but they are still moved past each other.  I expected any common
constraint would keep them from crossing.

(Adding "volatile" to all asms does prevent relative motion but inhibits other
optimizations so is undesirable.)
