When I compile qt334 with the actual snapshot of gcc41 I get an ICE when I
enable autovectorisation.

Nope the types are correct. The bug is in the middle-end when expanding VECTOR << VECTOR.

No, the bug is in the vectorizer that produces a LSHIFT_EXPR rather than a
VEC_LSHIFT_EXPR. There must have been problems committing the patch. :-(

Not even that... the backend for i386 accepts an SI, not a V4SI, as the shift
count. This upsets the expander noticeably.

This causes a build failure if you turn on -ftree-vectorize when building the target libraries.
