[Activity] [TCWG-1319] Link AOSP with LLD. Closed this out as I've gone as far as I can profitably go without being an Android expert. - With trunk LLD I can now link and boot AOSP with LLD without any use_clang_lld=false on both Arm and AArch64 emulators. I also managed to get it to boot on a Hikey960 (aarch64). - Communicated recent additions to LLD in aid of building AOSP, and extra command line options needed to the Google team. Landed support for GCC inline assembly constraint S in LLVM. Some comments on LTO + linker script proposal on llvm-dev mailing list. Started thinking in more detail about ICF=safe. - Decided that LLVM was a better place to do this than clang after attempting to use libtooling. - There is an existing LLVM pass called merge functions that does what ICF does but at the LLVM IR level -- This is off by default, maybe worth looking at as part of LTO and code-size reductions. - Started to write a prototype pass that uses Function::isAddressTaken() although I think that this may give me too pessimistic a result.

Progress: [short week, 3 days] * VIRT-65 [QEMU upstream maintainership] + code review - make system registers visible via gdbstub - Richard's patches to fix various softfloat issues * VIRT-164 [improve Cortex-M emulation] + MPC emulation: - rebased and fixed up conflicts with a different series that touched the same parts of the memory system - realised that passing txattrs to IOMMUs means we need to change the notifier API; came up with a plan to handle this by using "IOMMU indexes" analogous to our existing TCG MMU indexes. Updated everything to the new API that comes out of that approach. - started on tidying up the final loose ends; hope to have something I can send to the list early next week thanks -- PMM

[VIRT-243 # ARMv8.1-Atomic instructions ] v3 posted and merged. [Upstream] (Upgraded my laptop to Fedora 28, which lead to...) Posted a patch for gcc 8 Werrors. Posted patches for clang 6 Werrors. Sent pull for Emilio's TranslateOps patches. Sent pull for my openrisc decodetree patches. Sent pull for tcg-next. Reviewed microblaze patches. Posted two rounds of softfloat snan patches. Posted two rounds of fp16 patches. [VIRT-198 # QEMU: SVE Emulation Support ] Most of this week's work was on indirectly related patch sets. In particular, fp16 and atomics. The last round of check-gcc testing had FAIL: gcc.dg/vect/slp-multitypes-2.c execution test FAIL: gcc.target/aarch64/advsimd-intrinsics/vldX.c -O0 execution test FAIL: gcc.target/aarch64/advsimd-intrinsics/vqtbX.c -O0 execution test as the only remaining (relevant) failures. I believe that the latter two are generic tcg failures that are cured by this week's tcg-next pull, but have not yet re-based everything to be sure. r~

Linaro provides only cross-toolchain binaries and we rely on distro to provide native toolchains. In particular, Ubuntu is using Linaro toolchain sources for their gcc-7 builds, so this is the closest one to linaro toolchain. Debian uses FSF sources. -- Maxim Kuvyrkov www.linaro.org

Do we have native aarch64 toolchain GCC 7.3 for Arm servers?

by Guodong Xu

Hi, Maxim Do we have any build for native aarch64 toolchain GCC 7.3? I checked snapshots.linaro.org: https://snapshots.linaro.org/components/toolchain/gcc-linaro/7.3-2018.04/ But it only has x86 versions. Somebody pinged me from the 96boards community to ask for that. He asked for GCC 7.3. What being used in ERP 17.12, as I checked, is GCC 6.3. Thank you very much. Best regards, Guodong Xu

[ACTIVITY] report week ending 4th May

by Peter Smith

[Activity] [TCWG-1384] - Implemented missing TLS LE relocations in LLD - Found out while testing that LLVM had the range check in locally resoloved fixups for Thumb2 BL wrong, and was not range checking B.w or Bcc.W at all. Patches submitted for review. [LLD] - Submitted extra test cases to improve code-coverage - Arm LLD 2 stage build-bot including test suite now configured (thanks Maxim!), will be active upstream soon. - Started to think about how ICF could be implemented in clang -- Should be able to make a prototype using clang libtooling [TCWG-1236] - Added aarch64 emulation used by Android to LLD - Tried and failed to get Android to boot when using LLD, narrowed down the number of modules that could be problematic but I think that the main symptom is dlopen failing on some modules. - Found that Google have added LLD support to the Android build system with a very slightly tweaked version of LLD. This will successfully boot Android. The main differences are: -- Google's LLD is a few weeks behind trunk. -- They have reverted a couple of patches that add undefined symbols from Shared Objects and allow these to resolve against static libraries. These patches are correct and I think it is just exposing some library dependency problems in Android. -- They are setting -zmax-page-size to 4K on AArch64, LLD defaults to 64K. --- Android dynamic linker does use 4K page size, but Gold still seems to use a 64K max page size and I can't see why overaligning would cause problems. -- A handful of modules have LLD disabled. [Plans] - Investigate differences in trunk and Google Android LLD to see if I can pinpoint why trunk is failing to boot Android. - Start to build a prototype with libtooling that records when the address of a function/member-function/lambda is taken.

[ACTIVITY] report week ending 4 May

by Peter Maydell

Progress: * VIRT-65 [QEMU upstream maintainership] + code review: - RTH's v8.1 atomics emulation patchset - bugfix to cmsdk UART model - bugfix to MPUIR access check for OMAP/StrongARM emulation - Alex's float-to-float conversion refactoring - SMMUv3 now fully reviewed and in target-arm.next + tracked down a bug in our handling of "DUP" vector instruction that turned out to be in the new x86 codegen backend that tries to use MMX instructions and wasn't quite getting it right. Patch sent. * VIRT-164 [improve Cortex-M emulation] + working on emulation of Memory Protection Controller; I think we can do this neatly using QEMU's IOMMU emulation framework, but it needs some improvements to the framework to make that work: - feed memory transaction attributes to the IOMMU translate function so it can use secure/nonsecure attribute to make decisions - allow TCG code to handle accessing data and executing from RAM that's on the far side of an IOMMU (currently it asserts if you set up a system with an IOMMU in the CPU's data path) I have some prototype patches that deal with these and use them in an MPC model, which need debugging. thanks -- PMM

[ANNOUNCE] Linaro GCC 6 and 7 2018.04 source snapshots

by Mark Murray

The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2018.04 snapshot of Linaro GCC 6 and 7 source packages. o The GCC 7 series introduced an ABI change for ARM targets by fixing a bug (present since GCC 5, see link below) that affects conformance to the procedure call standard (AAPCS). The bug affects some C++ code where class objects are passed by value to functions and could result in incorrect or inconsistent code being generated. If the option -Wpsabi is enabled (on by default) the compiler will emit a diagnostic note for code that might be affected by this ABI change. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77728 For an explanation of the changes please see the following website: https://gcc.gnu.org/gcc-7/changes.html o Linaro GCC 7 monthly snapshot[1] is based on FSF GCC 7.3+svn259627 and includes performance improvements and bug fixes backported from mainline GCC. The contents of this snapshot will be part of the 2018.05 stable[2] quarterly release. This snapshot tarball is available on: http://snapshots.linaro.org/components/toolchain/gcc-linaro/7.3-2018.04/ Interesting changes in this GCC source package snapshot include: * Updates to GCC 7.3+svn259627 o Linaro GCC 6 monthly snapshot[1] is based on FSF GCC 6.4+svn259634 and includes performance improvements and bug fixes backported from mainline GCC. This snapshot contents will be part of the next maintenance release. This snapshot tarball is available on: http://snapshots.linaro.org/components/toolchain/gcc-linaro/6.4-2018.04/ Interesting changes in this GCC source package snapshot include: * Updates to GCC 6.4+svn259634 o Subscribe to the important Linaro mailing lists and join our IRC channels to stay on top of Linaro development. ** Linaro Toolchain Development "mailing list": http://lists.linaro.org/mailman/listinfo/linaro-toolchain ** Linaro Toolchain IRC channel on irc.freenode.net at @#linaro-tcwg@ * Bug reports should be filed in Bugzilla against GCC product: http://bugs.linaro.org/enter_bug.cgi?product=GCC * Interested in commercial support? inquire at "Linaro support": mailto:support@linaro.org [1]. Source package snapshots are defined when the compiler is only put through unit-testing and full validation is not performed. [2]. Stable source package releases are defined as releases where the full Linaro Toolchain validation plan is executed.

* Short week - a public holiday * Return jump function - Writing up issues with test cases for upstream discussion based on the ipa-cp implementation * LLVM astar regression - Trying to reproduce with trunk LLVM vs trunk gcc - Clang build fails in tx1 (likely due to not enough memory ?) - Set it up on dev-01. I see about ~2% difference. The difference goes away when I use -fno-devirtualize-speculative. This suggests the issue is still present. Perf results are also consistent with this. - Reducing a self-contained test case

Activity: [TCWG-1384] Add support for missing TLS local exec relocations tl LLD Have an implementation ready to go upstream next week. In process found that Gold and BFD disagreed on test output. Turns out that there was a bug in BFD, reviewed Renlin Li's patch for it. Took rather more of my time than I expected. [TCWG-1375] Set 4 patches upstream to complete the removal of the global subtarget No response as yet. Raised https://bugs.llvm.org/show_bug.cgi?id=37212 clang and gcc are producing technically illegal ELF for debug information (references to local symbols defined in comdat groups), both gold and bfd have special case code to handle this case, lld does not. Leads to loss of debug illusion for templated and inlined C++ functions. Other - Some research into how spec files and multilib works in gcc to see how it could fit into clang's driver model. - Joined the ELF ABI google group to fulfil a promise I'd made at Euro LLVM to comment on a thread about debug information in comdat groups. Holiday on Tuesday Plans: - Ping reviews. - Push fix for TCWG-1384 upstream alongside some refactoring patches. - Add some more tests to LLD to close some holes in the code-coverage statistics. - Continue looking at laundry list of small LLD changes. - Get back to building Android.

Progress: * VIRT-65 [QEMU upstream maintainership] + 2.12 release kicked out the door; hopefully I can do a bit more actual development work for a bit now... + investigating problems with execute-in-place-from-MMIO-device functionality : the test case (for a Xilinx board model) crashes reliably for me. I cooked up an RFC patch and sent it, but it includes one weird hack and I'm not sure if it's the right approach... + we got a Coverity Scan run through after a couple of months of not having one, and a pile of issues have accumulated. Waded through some of them and flagged them up with the patch submitters who added the code that introduced them. Notes: * QEMU will have not one but two interns working on Cortex-M0 and micro:bit support (one from Google Summer of Code and one from Outreachy) ! * QEMU turns 15 years old this year. To celebrate we plan to make the next release be 3.0 (and perhaps to have birthday cake at KVM Forum?) thanks -- PMM

[QEMU Upstream] Fix for softfloat scalbn, broken during the 2.12 reorg. Code review for Alex's tcg/tests patchset. Produced a script describing how to build cross-compilers. [VIRT-198 # QEMU: SVE Emulation Support ] Fix an tcg generic vector assert hitting SVE w/ VQ=3. Rebase and post cleanup patch for TCGv_ptr operations. Finished round 2 of SVE cleanup and fixes. RISU now once again passes for VQ in [1-4] (which is the limitation of the FoundationModel against which we are generating trace files). I'll note that a lulesh binary that I generated for HKG18 does not work on the branch, but does under FoundationModel. Therefore there must be remaining emulation errors. However, it's a really complicated binary that is non-debuggable. Adding printfs interferes with vectorization and gdb does not yet let us print all of the relevant registers. My thoughts from here go toward running the gcc testsuite, and seeing what can be uncovered by those smaller examples. r~

Progress: Monday Tuesday at Euro LLVM, trip report at https://collaborate.linaro.org/display/CR/20180416+EuroLLVM+2018 Found an example that shows that both gold and ld attempt to fix up illegal "by strict interpretation of ELF" local debug references to discarded local symbols from rejected comdat groups. [TCWG-1375] LLVM should do relaxation per function. - Worked out what instruction bundling is (From NaCl) and how it relates to MCFragments. - Posted revised patch upstream to handle relaxation and fixups, now diagnoses attempt to change MCSubtargetInfo mid bundle. - I have a finished a large series of patches to pass the MCSubtargetInfo through to all the places it needs to be including writeNops. Will post upstream review next week. Next week: - Post revised patches to TCWG-1375 and ping reviews. - Work through a laundry list of small things to do in LLD. - Get back to trying to link Android AOSP with LLD.

[ACTIVITY] report week ending 13 Apr

by Peter Maydell

Progress: * VIRT-65 [QEMU upstream maintainership] + sent patch fixing problem where some aarch64 binaries would segfault under linux-user (changes for SVE accidentally caused them to get a too-small signal frame) + wrote an RFC kernel patch which sanitizes the ESR value reported to userspace for faults on kernel addresses, rather than dropping it entirely + wrote a patch to fix a reported QEMU compile failure for Arm guests on MIPS hosts + code review: - various bug fixes for 2.12 - another round of the patchset to implement the PMU properly - DS1338 RTC device emulation overhaul patches - QEMU side of changes to allow more than 123 CPUs with KVM (mostly involving allowing split GIC redistributor regions) - linux-user FDPIC ABI support Hopefully next week I'll be able to get back to non-release related work... thanks -- PMM

[TCWG-1375] Make sure MCSubtargetInfo is passed through to ARMAsmBackend functions Spent most of the week working on this and follow up patches. Have submitted a patch for the most important functions. Nearly have one ready for the correct Nop encoding, this is more complicated as Nops can be used as padding. [Plans] In office Monday Tuesday only. Progress [TCWG-1375] Planned Absences: - At ACCU conference Wednesday - Friday [Holiday] - At Euro LLVM following Monday Tuesday

[VIRT-198 # QEMU: SVE Emulation Support ] Cleaning up patches and fixing RISU failures. Most of these have thankfully been errors in last week's first pass reordering of the sve_access_check. Typically wrt when we find the address of a register vs the location of the check vs assert_fp_access_checked. [Upstream] Examined a bug affecting aa64 guest on ppc64 host, but only when using gcc 4.8.5 and not gcc 7.2. Fixed; in the end a minor typo on the code, but highly annoying to track down. r~

[ACTIVITY] report week ending 6 Apr

by Peter Maydell

Progress: (short week, 2 days) * VIRT-65 [QEMU upstream maintainership] + email/code review/etc catchup following holiday + the usual run of admin work for the release process for rc2 + investigated a problem where in 'icount' mode we weren't firing timer interrupts in a timely manner; with assistance from Paolo, tracked down the cause and sent a patch (https://bugs.launchpad.net/qemu/+bug/1754038) + investigated a problem with v7M emulation reported by the LITE team; this turned out to be a combination of a known limitation combined with a badly worded warning message; sent QEMU patch which rewords the message so it's clearer that it's telling you that you're running into the limitation. + tracked down why aarch64 guest binaries run in icount mode on a 32-bit host misbehave; I have a working but slightly ugly patch which I'll send out next week unless somebody has a neater approach thanks -- PMM
