Just FYI. This test is just bogus and fixing it might be simple as using -fsanitize=undefined to check at runtime there is no undefined behavior being hit.
In this case even if we do the comparison in `signed` and do the negate in `unsigned` types. we can still remove the negate in this case since we know the only value that will be still negative in that branch is LONG_MIN. So my patch just simplifies the inner comparison to that instead of `a < 0` and then be able to remove the neg. Someone else will have to fix the testcase since it is a testcase issue ... ________________________________________ From: ci_not...@linaro.org <ci_not...@linaro.org> Sent: Friday, September 1, 2023 3:07 PM To: Andrew Pinski Subject: [EXT] [Linaro-TCWG-CI] 2 patches in gcc: FAIL: 1 regressions External Email ---------------------------------------------------------------------- Dear contributor, our automatic CI has detected problems related to your patch(es).
