Fwd: [Linaro-TCWG-CI] gcc patch #133364: 113 regressions on aarch64

Hello there, According to the list of regressions below, all the failing tests are for the C compiler. I am at a bit of a loss to know how to proceed since the patch that you have fingered applies exclusively to fortran.

Re: [Linaro-TCWG-CI] 5 patches in gcc: 1 regression on arm

by Álvaro Begué

This test failure is pre-existing on master and is not introduced by this series. I verified that vanilla master (commit d3e7d81adc8, the baseline cited by the CI report) produces identical output to the patched build for the Egypt walk in test_egypt() — the diff is empty. The test's hardcoded expected output expects ambiguous local_info results at certain EEST→EET fall-back transitions (2003, 2005, 2007, 2009, 2010), but the current master code produces two consecutive unique EET intervals instead (a 1-hour interval followed by the long winter interval, same offset/save/abbrev). This looks like a pre-existing consequence of the merge block in _M_get_sys_info being #if 0'd out. --Álvaro.

Re: [Linaro-TCWG-CI] gcc-16-6952-g14cd2833b27a: 7 regressions on master-thumb_v8a_hard_eabi

by Alexandre Oliva

The test fails on arm-eabi when testing with the following settings: -mlittle-endian -mfloat-abi=hard -mcpu=cortex-a9 -mfpu=vfpv3 It only fails in the following torture option set: -O3 -fomit-frame-pointer -funroll-loops -fpeel-loops -ftracer -finline-functions It also fails on numerous other 32-bit targets, but it depends on how the memcpy-like loop gets vectorized and unrolled.

Potentially dodgy caching on flang-arm64-windows-msvc

by Luke Lau

Hi there, I got a notification about a build failure on the flang-arm64-windows-msvc buildbot earlier today, I’ve included the original email below. The commit in question that caused the failure added some new intrinsics, touching some tablegen files, which then caused some tests for unrelated intrinsics to fail: https://github.com/llvm/llvm-project/commit/9ba774566e27b76b9c7c2b2ddd108c1… https://lab.llvm.org/buildbot/#/builders/207/builds/15865 But the buildbot went back to green in https://lab.llvm.org/buildbot/#/builders/207/builds/15869 when another PR changed some other tablegen files in the llvm project. I didn’t revert or commit any fixes in the meantime. Is there maybe some issue with the build cache and how tablegen files interact with it? Just thought I’d flag this to you anyway.
