Re: [Linaro-TCWG-CI] llvmorg-24-init-10324-gfa939745e0ac: 1 regression on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, This test is incorrect. This is a test configuration issue caused by an inappropriate floating-point tolerance setting. Updating the test to use the standard FP32 tolerance resolves the failure while preserving the intended validation of single-precision numerical results. Please ignore the mail. We'll update the test. We apologize for the false detection.

Re: [Linaro-TCWG-CI] llvmorg-24-init-8067-gf40e465b112a: 13 regressions on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, These tests are incorrect. Therefore, we will correct the tests. The investigation concluded that all 13 failures are caused by expected floating-point precision differences introduced by reassociation enabled by commit #222302. No compiler malfunction was identified. The affected test cases contain overly strict or incorrect tolerance settings and should be updated accordingly. Please ignore the mail. We'll update the test. We apologize for the false detection.

Re: [Linaro-TCWG-CI] llvmorg-24-init-8067-gf40e465b112a: 13 regressions on aarch64

by Tom Eccles

Thank you for pointing out the issue. I believe this is a problem with the Fujistu test suite. I’ve created an issue there https://github.com/fujitsu/compiler-test-suite/issues/147 The fortran standard explicitly allows reassociation of floating point operations within a single programming language statement. The tests are too strict, passing only for strict left-to-write lowering of all floating point expressions. As discussed in the RFC, https://discourse.llvm.org/t/rfc-flang-reasssociate-within-real-and-complex… this was expected. The only difference was that with this more recent patch more tests than I anticipated were affected.

Re: [Linaro-TCWG-CI] llvmorg-24-init-7065-g70d088d10d20: 1 regression on aarch64

by Yasuyuki Ohno (Fujitsu)

Hi, This test is incorrect. Therefore, we will correct the test. The issue became visible after LLVM commit(70d088d) changed symbol resolution behavior to prefer a specific procedure defined in a generic interface over an explicitly declared intrinsic procedure. As a result, int(1,1), which had previously been resolved as the intrinsic function INT(A,KIND), is now resolved as ifunc01(1,1). Consequently, its result changes from 1 to 2. Because the test still assumes the previous behavior and retains the corresponding expected output, the failure is exposed. To address this issue, the test should be updated to verify the results of the intrinsic function INT and the specific procedure ifunc01 independently. Before: if (int(1).ne.int(1,1)) print *,'error' After: if (int(1).ne.1) print *,'erro*' if (*nt(1,1).ne.2) print *,'error' This change explicitly verifies that the intrinsic function INT returns 1 and that the specific procedure ifunc01 associated with the generic interface returns 2, eliminating the dependency on the previous symbol resolution behavior. Please ignore the mail. We'll update the test. We apologize for the false detection. 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: 2026 年 9 月 4 日 (金曜日) 21:34 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>; ali.bahrani94521036(a)gmail.com <ali.bahrani94521036(a)gmail.com> 件名: [Linaro-TCWG-CI] llvmorg-24-init-7065-g70d088d10d20: 1 regression on aarch64 Dear contributor, Our automatic CI has detected problems related to your patch(es).
