--- Comment #1 from Feng Xue <fxue at os dot amperecomputing.com> ---
Both cases will be simplified with new pattern, and this is correct. Will
change test code to make that not happen.

testsuite/97066 - minor change to bypass plusminus-with-convert rule
The following testcases will be simplified by the new rule
(T)(A) +- (T)(B) -> (T)(A +- B), so could not keep code pattern
expected by test-check. Adjust test code to suppress simplification.
