Progress: * UM-2 [QEMU upstream maintainership] - release work: rc5 Monday, and then 6.0 final release on Thursday. - sent a pullreq with some accumulated arm patches now 6.1 is open - fixed a trivial bug where WFI in the usermode emulator crashed * QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)] - Implemented more instructions: logic ops, VCLS, VCLZ, VREV, VMVN, VABS, VNEG, VADD, VDUP, VSUB, VMULH, and widening VLDR. (These are all simple "always call an out-of-line helper" versions. We'll want an optimised "we know we have no predication" version for many of them, but I plan to do that afterwards.) - Worked through the v8M Arm ARM identifying which insns we must implement. There are 210 insn patterns in total, of which I have currently implemented 23, so we can produce a rough-and-ready progress meter: 23/210 (11%) (There is of course work to do beyond just the insns, but they form the bulk of it, so the meter has some utility.) -- PMM

Progress: * UM-2 [QEMU upstream maintainership] - Finished and posted patches implementing remap support for AN524 - Release work for rc3 - Sent a set of refactoring patches that split out some files we were previously #including into translate.c so they are separate compilation units. - Thought a bit more about reset handling (in the course of writing the AN524 remap patches I again ran into some of the deficiencies of our current reset implementation; I really must take some time this release cycle to try to improve things here...) - Fixed bug where our AN547 board model accidentally disabled the FPU on the Cortex-M55... - ...and one where we were accidentally giving it an M33 rather than an M55 ! - Respun and extended some patches from Paolo which fix our use of QEMU and system headers in the 2 C++ files in the codebase (which were broken by a change in new versions of glib) - started looking at some of the for-6.1 patch review queue, which I had been postponing in favour of for-6.0 stuff * QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)] - re-read the MVE portions of the v8M Arm ARM, sketched out a plan of where to start with the QEMU implementation thanks -- PMM

qemu bfloat16 branch

by Richard Henderson

https://gitlab.com/rth7680/qemu/-/commits/tgt-arm-bf16 It isn't a large extension, so all done. I added aarch64 simd, aarch32 neon, and sve support all at once. I've tested it via risu vs FVP. I've based this on my SVE2 branch, since there are some cleanups that made that easier. I'll post patches to qemu-devel next week. r~

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

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.

Pre-commit CI with libc++

by Louis Dionne

Folks, I am pleased to announce the move of libc++ to pre-commit CI. Over the past few months, we have set up Buildkite jobs on top of the Phabricator integration built by Mikhail and Christian, and we now run almost all of the libc++ build bots whenever a Phabricator review is created. The bots also run when a commit is pushed to the master branch, similarly to the existing Buildbot setup. You can see the libc++ pipeline in action here: https://buildkite.com/llvm-project/libcxx-ci. This is great -- we’ve been waiting to set up pre-commit CI for a long time, and we’ve seen a giant productivity gain since it’s up. I think everyone who contributes to libc++ greatly benefits, seeing how reviews are now used to trigger CI and improve our confidence in changes. This change does have an impact on existing build bots that are not owned by one of the libc++ maintainers. While I transferred the build bots that we owned (which Eric had set up) to Buildkite, the remaining build bots will have to be moved to Buildkite by their respective owners. These builds bots are (owners in CC): libcxx-libcxxabi-x86_64-linux-debian libcxx-libcxxabi-x86_64-linux-debian-noexceptions libcxx-libcxxabi-libunwind-x86_64-linux-debian libcxx-libcxxabi-singlethreaded-x86_64-linux-debian libcxx-libcxxabi-libunwind-armv7-linux libcxx-libcxxabi-libunwind-armv8-linux libcxx-libcxxabi-libunwind-armv7-linux-noexceptions libcxx-libcxxabi-libunwind-armv8-linux-noexceptions libcxx-libcxxabi-libunwind-aarch64-linux libcxx-libcxxabi-libunwind-aarch64-linux-noexceptions The process of moving these bots over to Buildkite is really easy. Please take a look at the documentation at https://libcxx.llvm.org/docs/AddingNewCIJobs.html#addingnewcijobs and contact me if you need additional help. To make sure we get the full benefits of pre-commit CI soon, I would like to put a cutoff date on supporting the old libc++ builders at http://lab.llvm.org:8011/builders. I would propose that after January 1st 2021 (approx. 1 month from now), the libc++ specific build bots at lab.llvm.org be removed in favor of the Buildkite ones. If you currently own a bot, please make sure to add an equivalent Buildkite bot by that cutoff date to make sure your configuration is still supported, or let me know if you need an extension. Furthermore, with the ease of creating new CI jobs with this infrastructure, we will consider any libc++ configuration not covered by a pre-commit bot as not explicitly supported. It doesn’t mean that such configurations won’t work -- it just means that we won’t be making bold claims about supporting configurations we’re unable to actually test. So if you care about a configuration, please open a discussion and let’s see how we can make sure it's tested properly! I am thrilled to be moving into the pre-commit CI era. The benefits we see so far are huge, and we're loving it. Thanks, Louis PS: This has nothing to do with a potential move or non-move to GitHub. The current pre-commit CI works with Phabricator, and would work with GitHub if we decided to switch. Let’s try to keep those discussions separate :-). PPS: We’re still aiming to support non libc++ specific Buildbots. For example, if something in libc++ breaks a Clang bot, we’ll still be monitoring that. I’m just trying to move the libc++-specific configurations to pre-commit.

[VIRT-349 # QEMU SVE2 Support ] I have a working FVP SVE2 install! I used a new FVP version (11.13.36) from the last time that I tried (11.13.21 on Jan 27). I used a debian-testing snapshot from 1-MAR, which has linux 5.10 bundled, and fvp revc dtb installed. I used https://git.linaro.org/landing-teams/working/arm/arm-reference-platforms.gi… (which is linked to by one of the howtos that Peter forwarded) and chose the "pre-built uefi" version. I need to report a bug on this build script -- the "build from source" option does not work on a system that has all python3 and no python2.

What does suffix ' ... isra.0' mean in compiled symbols in GCC 10.2?

by Guodong Xu

Hi, all Does anybody know what does '.....isra.0' mean in GCC 10.2 compiled objects? I just noticed this issue when using bcc/eBPF tools. I submitted the detail into * https://github.com/iovisor/bcc/issues/3293 Simply put, when building a linux kernel with GCC 10.2, the symbol 'finish_task_switch' becomes 'finish_task_switch.isra.0' in the object (as reported by 'nm') Because a lot of kernel tracers (such as bcc) use 'finish_task_switch' as the probe point, this change in the compilation result can make all result such tools fail. Thanks. Best regards, Guodong Xu

Clang targetting x64 linker

by Joel Cox

Hi I've been trying to run clang on a Windows on Arm machine, but it keeps trying to using the link.exe located in "Visual studio/..../Host64/arm64", which is (seemingly) an x64 tool and as such doesn't run, and crashes the process. Is there a way to set clang to look at VS's x86 link.exe? Or if there is an arm64 version that clang should be using instead?

LLVM12 Clang doesn't start

Hi, I've been trying to use clang on Windows on Arm machine (Samsung Galaxy Book S), but whenever I try to use it, I get either nothing (in powershell) or an error popup: "The application was unable to start correctly (0x000007b)".

Many of your builders are red for long time

by Galina Kistanova

Hello Linaro Toolchain Working Group, libcxx-libcxxabi-libunwind-armv8-linux has been red for 5 days. clang-cmake-aarch64-global-isel has been red for 10 days. clang-cmake-aarch64-quick has been red for 10 days. clang-cmake-armv7-global-isel has been red for 10 days. clang-cmake-armv7-lnt has been red for 10 days. clang-cmake-aarch64-lld has been red for 11 days. clang-cmake-armv8-lld has been red for 11 days. clang-cmake-thumbv7-full-sh has been red for 11 days. clang-cmake-armv7-full has been red for 11 days. Is anybody looking at this? I also noticed that some of your workers are less reliable than others. For example, inaro-tk1-09 worker was last time producing a green build 2 months ago - http://lab.llvm.org:8011/#/workers/2?numbuilds=500 I'm removing the linaro-tk1-09 worker from the production buildbot for now. Please feel free to connect it to the staging and make the builder reliably green. Then it could be returned back to the production. linaro-armv8-windows-msvc-01 and linaro-armv8-windows-msvc-02 have been red for the least 4 months. I'm removing them from the production buildbot. You can return them back to production after they are reliably green in the staging. Please feel free to ask if you have questions. Thanks Galina

Progress: * UM-2 [QEMU upstream maintainership] + sent out a small code-cleanup patchset for some arm display device models to remove no-longer-needed support for non-32bpp outputs + tracked down (with the aid of Paolo) why our build system had started building the documentation every time you run 'make'; sent a fix + code review todo queue status: 12 items, but the oldest was only sent to the list on Monday... * QEMU-364 [QEMU support for ARMv8.1-M extensions] + An MPS3 Cortex-M55 FPGA image is now publicly available: the AN547. We'll provide a model of this in QEMU. Started working on the patchseries to implement it (relatively small changes on top of the SSE-300 work I've already done but not sent out, and the mps3-an524 series I sent out for review last week). This is basically code-complete but I need to do some more testing and ideally I'd like the AN524 series to get reviewed before I send out another 40-patch series that would have to be based on top of that one. thanks -- PMM

Re: [lldb-dev] 12.0.0-rc1 Release has been tagged

Hello, I've uploaded binaries for Windows on Arm: 081373cc76e88224020fea42eba2161d972f03bb83ebc055fb3cd4f2cfcdfb95 LLVM-12.0.0-rc1-woa64.exe It was built from the current release/12.x branch (commit b46924ee) with two patches applied on top: - https://reviews.llvm.org/D96259 - https://reviews.llvm.org/D96498 It contains "clang;clang-tools-extra;lld;compiler-rt” projects. Compiler-RT has sanitizers disabled (MEMPROF and XRAY use sanitizer infrastucture). I.e., === + -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra;lld;compiler-rt" ^ + -DCOMPILER_RT_BUILD_SANITIZERS=OFF ^ + -DCOMPILER_RT_BUILD_MEMPROF=OFF ^ + -DCOMPILER_RT_BUILD_XRAY=OFF ^ === I've attached the changes we had to make to llvm/utils/releases/build_llvm_package.bat. @Maxim Kuvyrkov is going to clean them up and post a patch in the next couple of weeks (he's been doing all the hard work, I'm just uploading). This is the first time we're trying to provide a release for Windows on Arm, so if anyone has any comments or questions, feel free to send an email :) Cheers, Diana On Thu, 28 Jan 2021 at 05:05, Tom Stellard via lldb-dev < lldb-dev(a)lists.llvm.org> wrote: > Hi, > > I've tagged the 12.0.0-rc1 release.
