Hello all,
I have now committed the attached patch, which postpones CFI debug 
labels occuring in the middle of a vliw insn. Thanks

Cheers
Hari

ChangeLog:
         * config/picochip/picochip.c (picochip_output_internal_label):
          This function can now be called for debug CFI labels, which 
can come in the middle of a vliw instruction. Postpone until end of vliw.
