[Bug middle-end/38428] [4.4 Regression] ice for Linux kernel code with -O2



------- Comment #4 from jakub at gcc dot gnu dot org  2008-12-06 13:06 -------
Apparently caused by my PR37248 patch.  We have a volatile bitfield, and the
patch (similarly to 4.3) creates a TREE_THIS_VOLATILE TREE_SIDE_EFFECTS
BIT_FIELD_REF, but apparently the trunk is upset about it.

Either we just don't try to optimize volatile bitfields at all (don't create
BIT_FIELD_REFs for them), or some changes are needed to handle volatile
BIT_FIELD_REFs.
