Old Synopsis: [arm-thumb] pre_insert_copy_insn
New Synopsis: [arm-thumb] [regression 3.2 3.3 3.4] pre_insert_copy_insn

State-Changed-From-To: open->analyzed
State-Changed-By: rearnsha
State-Changed-When: Fri Jan 31 15:15:57 2003
State-Changed-Why:
    pre_insert_copy_insn expects a single_set insn, but is being given a parallel with multiple sets.  This is clearly an internal logic failure somewhere in GCSE.
