Hi,

The attached patch should fix PR 101737.  It's a rather obvious oversight. 
Sanity tested with 'make all-gcc'.  Committed to master, gcc-13, gcc-12,
gcc-11.

Cheers,
Oleg


gcc/ChangeLog:
	PR target/101737
	* config/sh/sh.cc (sh_is_nott_insn): Handle case where the input
	is not an insn, but e.g. a code label.
