Hi, Probably this error is false detections caused by precision errors in floating-point arithmetic. Please ignore the mail. We'll update the test. I apologize for the false detection.

I'm not sure yet another bug about these middle end warnings is useful! I'll let somebody else decide that. You can ignore it though, your patch isn't the problem here, it just revealed it.

It's not directly related to my patch (which optimizes moving a range, not filling it), but my patch changes the detection logic causing gcc to think the region is of size 0 (where it should be 4). Yes, these middle-end warnings are a plague, but I don't see why your patch (which I pushed yesterday) changes the __uninitialized_fill_n_a() path which uses memset.

Re: [Linaro-TCWG-CI] llvmorg-23-init-15424-g3def12d2a418: 1 regression on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, With the https://github.com/llvm/llvm-project/commit/3def12d2a418f8e49f0b88ddf9070af… , the result of `ieee_support_rounding()` for `ieee_other` has been corrected so that `.false.` is now the correct value. This test expects `.true.`, but following the correction above, the correct result is now `.false.`. Therefore, this test is incorrect. I apologize for the false detection. We'll correct this test. It may take some time due to our internal release process, sorry. Best regards, Yasuyuki Ohno Software Development Div., Advanced Technology Development Unit, Fujitsu Research, Fujitsu Limited, JAPAN. ________________________________ 差出人: ci_notify(a)linaro.org <ci_notify(a)linaro.org> 送信日時: 2026年5月16日 14:38 宛先: contact-ci-compiler-test-suite(a)cs.jp.fujitsu.com <contact-ci-compiler-test-suite(a)cs.jp.fujitsu.com> CC: maxim.kuvyrkov(a)linaro.org <maxim.kuvyrkov(a)linaro.org>; kwyatt.external(a)hpe.com <kwyatt.external(a)hpe.com> 件名: [Linaro-TCWG-CI] llvmorg-23-init-15424-g3def12d2a418: 1 regression on aarch64 Dear contributor, Our automatic CI has detected problems related to your patch(es).
