--- Comment #14 from Florian Fuchs <fuchsfl at gmail dot com> ---
fyi, maybe a workaround. sh_cannot_copy_insn_p() only checked the last element
of a PARALLEL, ashlsi3_d_call has a "clobbers" at this position of pattern, so
it missed. When I check all elements of pat, at least it fixed the compilation
of libgcc for sh2eb-linux-muslfdpic and didn't see more failures of sh
testsuite.
