New IRC Channel for Linaro Toolchain Working Group

by Matthew Gretton-Dann

All, During Connect the suggestion was made that each working group should have its own IRC Channel for discussions and topics relating to the group in particular (as opposed to #linaro which is 'generic' Linaro conversations). Therefore I have just set up #linaro-tcwg on Freenode for the Toolchain Working Group. This channel is public and open to anyone who wants to talk with the TCWG group about anything toolchain related. Thanks, Matt -- Matthew Gretton-Dann Toolchain Working Group, Linaro

[ACTIVITY] report week ending 26 Mar

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - tagged rc0 - various bug investigation/patches for 6.0-ish stuff: + machines with a 'platform bus' incorrectly treated all sysbus devices as hotpluggable: wrote and sent patchseries + respin of gpex pci-host "don't fault for unmapped MMIO/PIO window accesses" patch + document how to use gdbstub/gdb for a multi-cluster machine where the clusters are different gdb inferiors + looked for workarounds for macos Appkit bug where Apple broke menubars for apps that start off as console apps and programmatically switch themselves to being GUI apps; various online suggestions don't seem to help, except for "when app starts, force the Dock to become active and then grab back focus 200ms later". Maybe we'll do that, but it's pretty ugly... thanks -- PMM

== Progress == * GCC upstream validation: - Small improvement to pre-commit testing scripts to allow running a subset of the tests (and thus save a lot of time) * GCC - MVE autovectorization: - vcmp support of FP types OK. - testsuite cleanup: looking at current failures, only found issues with tests so far. Testing several small testsuite patches is taking a long time due to the number of configurations * Misc == Next == * MVE auto-vectorization/intrinsics improvements * GCC/cortex-M testing improvements & fixes * Resume GDB/FDPIC work

Please use staging for your new bots; clang-cmake-aarch64-full is red for a month

by Galina Kistanova

Hello Linaro Toolchain Working Group, Please connect your new bots to the staging first and make them reliably green there: linaro-aarch64-flang-debug linaro-aarch64-flang-latest-clang linaro-aarch64-flang-latest-gcc clang-cmake-aarch64-full is red for a month. https://lab.llvm.org/buildbot/#/builders/7?numbuilds=700 Could you move linaro-aarch64-full to the staging and make it green again, please? Please let me know if I could help or you have questions. Thanks Galina

Re: Clang targetting x64 linker

by Maxim Kuvyrkov

Hi Joel, Indeed, LLD is not configured to be used by default in LLVM-12.0.0-rc1. You need to add -fuse-ld=lld option for it to work. We’ll fix this in the final LLVM-12 release for WoA, which is expected in around 2 weeks. Thanks for catching this! c:\Users\tcwg\source\maxim>..\llvm-12.0.0-rc1\bin\clang-cl.exe hello.c clang-cl: error: unable to execute command: Couldn't execute program 'C:\BuildTools\VC\Tools\MSVC\14.28.29333\bin\Hostx64\arm64\link.exe': Unknown error (0xD8) clang-cl: error: linker command failed with exit code 1 (use -v to see invocation) c:\Users\tcwg\source\maxim>..\llvm-12.0.0-rc1\bin\clang-cl.exe -fuse-ld=lld hello.c c:\Users\tcwg\source\maxim>hello.exe Hello c:\Users\tcwg\source\maxim>..\llvm-12.0.0-rc1\bin\clang.exe -fuse-ld=lld hello.c c:\Users\tcwg\source\maxim>hello.exe Hello -- Maxim Kuvyrkov https://www.linaro.org > On 4 Mar 2021, at 19:43, Joel Cox <Joel.Cox(a)arm.com> wrote: > > Hi > > I was trying "clang hello.c" from command line, but "clang-cl hello.c" gives me the same error.

It’s easiest to use clang-cl.exe as it aims to be a direct replacement for MSVC’s cl.exe, but will use LLVM tools.
