Subject: testsuite/97066 - minor change to bypass plusminus-with-convert rule
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f419a0158950034ed9996ae860b0c8df03731119;p=gcc.git

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.
