But current pattern only accepts "ashiftrt": XX:SF=bitcast:SF(subreg(YY:DI>>32),0), but actually "lshiftrt" should also be ok. And current pattern only supports BE. Here, updating the pattern to support BE and "lshiftrt". PR target/108338 gcc/ChangeLog: * config/rs6000/predicates.md (lowpart_subreg_operator): New define_predicate. * config/rs6000/rs6000.md (any_rshift): New code_iterator. (movsf_from_si2): Rename to ... (movsf_from_si2_<code>): ... this. gcc/testsuite/ChangeLog: * gcc.target/powerpc/pr108338.c: New test.
