I couldn't figure out how to write a test for this. It looks like there are self tests but not a way to write standalone ones? I did create testcases in the patch 3/4 which tests the end result. gcc/ChangeLog: PR target/108583 * gimple-range-op.h (gimple_range_op_handler): Add maybe_non_standard. * gimple-range-op.cc (gimple_range_op_handler::gimple_range_op_handler): Use it.
