Could this be applied to gcc-4.6.4 please? A recently reported miscompilation
of a device driver in the Linux/ARM kernel by gcc-4.6.3 was traced to this bug.
Applying the trunk patch to 4.6.3 fixed that test case.
FWIW, I've been using and testing this fix in my own 4.6-based branch since
early March, on multiple targets, without regressions.
