Hello,

This patch changes find_reg_equal_equiv_note to be consistent with what
set_unique_reg_note does for REG_EQUAL/REG_EQUIV notes: Do not expect
to have them on insns with multiple sets.

Bootstrapped&tested on i686-pc-linux-gnu. OK for the trunk?

I suppose

gcc_assert (GET_CODE (PATTERN (insn)) != PARALLEL || !multiple_sets (insn));

doesn't work?

Richard.
