        * expmed.c (expand_shift): On SHIFT_COUNT_TRUNCATED targets, we may
        have stripped a SUBREG from the shift count, so we may need to
        convert_to_mode back to the type's mode before calling make_tree.
        Use new_amount instead of amount to avoid expanding a tree twice.

        * gcc.dg/pr27861-1.c: New test case.
