hash_scan_insn has the comment:
Single sets in a PARALLEL could be handled, but it's an extra complication
that isn't dealt with right now. The trick is handling the CLOBBERs that
are also in the PARALLEL. Later.
Is this comment still valid .. it doesn't match the current implementation.
Actually the current implementation appears to be busted since it records
multiple sets which is preventing me from building an ARM cross compiler.
I'm about to put together a patch for that problem which I believe is
due to:

* gcse.c (hash_scan_insn): Clean up calls to hash_scan_set.
