[Bug rtl-optimization/23837] [4.0 regression] Wrong code with REG_NO_CONFLICT notes (caused by combine)

["amylaar at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #36 from amylaar at gcc dot gnu dot org  2005-12-19 12:01 -------
While the patch will stop the bug from being triggered by the test case,
it does not fix th underlying combiner bug.

Any REG_NO_CONFLICT block could potentially be rendered invalid by an
inappropriate instruction combination.  The REG_NO_CONFLICT note must be
removed
when such a combination is made.
