[ACTIVITY] Week ending 24th May

by Peter Smith

Half of the week spent investigating identical code folding -icf=safe. Turns out that upstream have a proposal that is much further along so shifted focus on to doing as much as I can to help it along. Found out that for some use cases of AArch64 PIC the small code model is inappropriate as the code segments may not be 4k aligned. Started looking into what it would take to implement the tiny code model in LLVM (supports only small and large at the moment). Built a small prototype to handle the easiest absolute addressing case, much more work needed to handle PIC and TLS. Not a lot of tangible progress, but I think I have learned a bit more about LLVM. Planned Absences - Friday 25th May (holiday). - Monday 28th May (UK public holiday)

[ANNOUNCE] Linaro Binary Toolchain Release-Candidate GCC 7.3-2018.05-rc1

by Mark Murray

The Linaro Binary Toolchain ============================ The Linaro GCC 7.3-2018.05-rc1 Release-Candidate is now available. *Notice*: GCC 7.1 ABI change for arm*-*-* targets, and note for aarch64*-*-* targets From GCC 7.1 release notes: On ARM targets (arm*-*-*), a bug introduced in GCC 5 that affects conformance to the procedure call standard (AAPCS) has been fixed. 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. This is an ABI change. If the option -Wpsabi is enabled (on by default) the compiler will emit a diagnostic note for code that might be affected. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77728 GCC 5 and GCC 6 releases will continue to be affected by the ABI bug, since changing ABI in these releases is not practical. A warning enabled by -Wpsabi option was added to GCC 5 and GCC 6 toolchains to diagnose codebases that might be affected by the ABI bug. Additionally, this same bug was present in AArch64 backend in development versions of GCC 7. There was no releases of GCC with this bug present in AArch64 backend, therefore the release notes does not mention this. However, be advised that any code bases built with development versions of GCC 7 need to be recompiled with released version of GCC 7 to conform to ABI. For an explanation of GCC 7 series changes please see the following website: https://gcc.gnu.org/gcc-7/changes.html For help in porting to GCC 7 please see the following explanation: https://gcc.gnu.org/gcc-7/porting_to.html Download release-candidate packages from: (sources) http://snapshots.linaro.org/components/toolchain/gcc-linaro/7.3-2018.05-rc1/ (binaries) http://snapshots.linaro.org/components/toolchain/binaries/7.3-2018.05-rc1/ Previous snapshots and release-candidates are at: http://snapshots.linaro.org/components/toolchain/binaries/ Previous releases are at: http://releases.linaro.org/components/toolchain/binaries/ A description of the arm and AArch64 target triples can be found at: https://collaborate.linaro.org/display/TCWGPUB/ARM+and+AArch64+Target+Tripl… Host Requirements ================== Linaro officially supports the current and previous Ubuntu LTS releases (as of the time of this release).

Linaro bugzilla #3040 : CC1 and cc1plus cannot convert UTF-8. https://bugs.linaro.org/show_bug.cgi?id=3040 * The Linaro GCC 6.3-2017.05 snapshot added support for -mpure-code option to ARMv7-M and ARMv8-M targets. This option ensures functions are put into sections that contain only code and no data. * The GDB version was upgraded from GDB 8.0 to 8.1. * Previous versions of the Linaro GCC 6 toolchain, when -static -E/—dynamic-list are passed to the linker, might create executables with dynamic sections which aren’t supported by run-time. This was exhibited in Perf Tools build system and has been fixed upstream and backported into Linaro Binutils 2.27 branch. Linaro bugzilla #2926 : Perf tools compiled statically for AArch64 with Linaro release 6.1 and later ones was not statically linked. https://bugs.linaro.org/show_bug.cgi?id=2926 * The Linaro GCC 6.3-2017.03 snapshot fixed some ILP32 issues (TLS, exception handling, …) and these have been incorporated into this release. * Previous versions of the Linaro GCC 6 toolchain were incorrectly generating floating-point code for soft-float Linux targets (arm-linux-gnueabi, and armeb-linux-gnueabi). This escaped detection until recently because the soft-float targeted toolchains were configured to use general-purpose registers for passing floating-point values (which is what you would expect for soft-float toolchains) and the intra-routine floating-code was not noticed. The issue would only show up on targets that were run on hardware that truly didn't have floating-point hardware where the kernel did not trap and emulate floating-point routines. This has been solved in Linaro GCC 6.3-2017.02-rc2 by configuring the toolchain (using --with-float=soft) to generate code without any floating-point instructions at all (-mfloat-abi=soft). https://review.linaro.org/#/c/16968/2 This change should not break compatibility between existing binaries compiled with these toolchains since the float-point parameter passing ABI is still the same. * A bug/regression in the compiler has been identified whereby the target function that is invoked when calling a "weak" function directly is the "strong" override, whereas when calling the function via a pointer the "weak" implementation is used. This would be noticed as inconsistent function invocation when invoking directly vs. invoking via function pointer. This issue only affected 32-bit arm targets. This regression has been fixed upstream and backported into Linaro GCC 6.3-2017.02-rc2. GCC PR target/78253: [5/6/7 Regression] [ARM] call weak function instead of strong when called through pointer. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78253 Linaro bugzilla #2562: ARM GCC 5.2 call weak function instead of strong when called through pointer https://bugs.linaro.org/show_bug.cgi?id=2562 * MS Windows does not support symlinks and the MS Windows archive extractor does not properly deep copy the symlink target files/directories into the symlinked directory structure when unpacking the toolchain archive. This causes problems with missing dependencies when using the Linaro mingw toolchains, as identified in the following bugs: https://bugs.linaro.org/show_bug.cgi?id=2684 https://bugs.linaro.org/show_bug.cgi?id=2192 https://bugs.linaro.org/show_bug.cgi?id=2762 This has been solved by copying files rather than using symlinks when the mingw targetted toolchain archives are created. https://review.linaro.org/#/c/16415/ * Users of Linaro's toolchain have encountered problems when building projects with Autotools (specifically libtool): https://bugs.linaro.org/show_bug.cgi?id=2764 The Linaro binary toolchain release contained files with a .la suffix as artifacts of the toolchain build process. These .la files are helper files for libtool, but unlike a gcc install tree, they are not position independent and contain full paths. Since these artifacts contain absolute paths they can actually mislead user invocation of libtool into not finding required libraries (because they reference the build tree, not the install location) and hence breaking Autotools builds. These *.la file artifacts have been removed from Linaro toolchain binaries because they are unnecessary for users. * The Linaro GCC 6.3-2017.01 snapshot added further enablement for ARMv8-M and these have been incorporated into this release. * Compiling and statically linking some SPEC2006int tests against tcmalloc have been failing due to a problem with glibc's memory allocator function overrides. This was fixed upstream: https://sourceware.org/bugzilla/show_bug.cgi?id=20432 Backported into Linaro glibc 2.23: commit 058b5a41d56b9a8860dede14d97dd443792d064b Author: Florian Weimer <fweimer(a)redhat.com> Date: Fri Aug 26 22:40:27 2016 +0200 malloc: Simplify static malloc interposition [BZ #20432] * Host binaries for x86_64 linux hosts now have symbols and debug information stripped in order to reduce the size of the toolchain binary archives. This reduces the archive size from 1.5G to 600M for aarch64-linux-gnu target with the gcc-6-branch. * The GDB version was upgraded from GDB 7.11 in the Linaro GCC 6.1-2016.08 release to GDB 7.12 in the Linaro GCC 6.2-2016.11 release. * The Linaro GCC 6.2-2016.10 snapshot added AArch32 support for ARMv8.2 and ARMv8m, as well as some AArch64 fixes for ARMv8.2, and bug fixes merged from FSF GCC 6.2. This is available in the binary toolchain as of Linaro GCC 6.2-2016.11. * Basic tuning support for the Qualcomm qdf24xx was added to the Linaro GCC 6.2-2016.10 snapshot and is available in the binary toolchain as of Linaro GCC 6.2-2016.11. * IFUNC was disabled for baremetal targets, as it was causing test-suite failures, and is presently a Linux only feature. * The gold linker was added to this binary release. * Backported malloc_lock fix into Linaro newlib 2.4. commit 2665915cfc46aa6403bb2efd473c523d3167e0cb Author: Andre Vieira (lists) <Andre.SimoesDiasVieira(a)arm.com> Date: Thu Jun 16 12:23:51 2016 +0100 Re-enable malloc_lock for newlib-nano * Backported rawmemchr patch into Linaro newlib 2.4. commit e7b1ee2ea6aa3ee1da41976407410e6202a098c5 Author: Wilco Dijkstra <Wilco.Dijkstra(a)arm.com> Date: Thu May 12 16:16:58 2016 +0000 Add rawmemchr * Backported strlen fix when using Thumb-2 and -Os -marm into Linaro newlib 2.4. commit 5c02bcc086a96b174e1b9e1445a4a1770070107a Author: Thomas Preud'homme <thomas.preudhomme(a)arm.com> Date: Wed May 11 17:18:48 2016 -0400 Fix strlen using Thumb-2 with -Os -marm * Backported fix for semihosting ARM when heapinfo not provided by debugger into Linaro newlib 2.4. commit 5c9403eaf40951f8a4f55ed65f661b485ff44be7 Author: David Hoover <spm2(a)dangerous.li> Date: Thu Apr 21 07:12:24 2016 +0200 Fixed semihosting for ARM when heapinfo not provided by debugger. * Merged latest FSF glibc release/2.23/master into Linaro glibc 2.23. * Backported __ASSUME_REQUEUE_PI check Linaro glibc 2.23 branch. commit 2d20c3bf918cd94ebd4106693adb3a5c9272baba Author: Adhemerval Zanella <adhemerval.zanella(a)linaro.org> Date: Tue May 17 10:16:39 2016 -0300 Add runtime check for __ASSUME_REQUEUE_PI (BZ# 18463) * Backported removal of __ASSUME_SET_ROBUST_LIST from Linaro glibc 2.23 branch. commit bb8f09d72756186a3d82a1f7b2adcf8bc1fbaed1 Author: Adhemerval Zanella <adhemerval.zanella(a)linaro.org> Date: Mon May 16 19:01:10 2016 -0300 Remove __ASSUME_SET_ROBUST_LIST * Backported removal of __ASSUME_FUTEX_LOCK_PI from Linaro glibc 2.23 branch. commit e48b4e7fed0de06dd7832ead48bea8ebc813a204 Author: Adhemerval Zanella <adhemerval.zanella(a)linaro.org> Date: Mon May 16 10:35:25 2016 -0300 Remove __ASSUME_FUTEX_LOCK_PI * Merged latest FSF binutils-2_27-branch into linaro_binutils-2_27-branch. * The libwinpthread DLL is now copied into the host bin directory to satisfy mingw package dependencies. * Backported GNU Linker fix. commit fbc6c6763e70cb2376e2de990c7fc54c0ee44a59 Author: Nick Clifton <nickc(a)redhat.com> Date: Tue Aug 23 09:45:11 2016 +0100 Fix seg-fault in ARM linker when trying to parse a binary file. * Backported GNU Assembler fix for PR 20364 commit 5fe7ebe5ab43750abf8f490b785d99a1e598e7fd Author: Nick Clifton <nickc(a)redhat.com> Date: Fri Aug 5 10:37:57 2016 +0100 Fix the generation of alignment frags in code sections for AArch64. https://sourceware.org/bugzilla/show_bug.cgi?id=20364 * Performance related backports from the following snapshots have been included: Linaro GCC 6.1-2016.06, Linaro GCC 6.1-2016.07, Linaro GCC 6.1-2016.08, Linaro GCC 6.2-2016.09, Linaro GCC 6.2-2016.10, Linaro GCC 6.2-2016.11, Linaro GCC 6.2-2016.12, Linaro GCC 6.3-2017.01, Linaro GCC 6.3-2017.02, Linaro GCC 6.3-2017.03, Linaro GCC 6.3-2017.04, Linaro GCC 6.3-2017.05, Linaro GCC 6.3-2017.06, Linaro GCC 6.4-2017.07, Linaro GCC 6.4-2017.08, Linaro GCC 6.4-2017.09, Linaro GCC 6.4-2017.10 and Linaro GCC 6.4-2018.04.

[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

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] week ending 27th April 2018

by Peter Smith

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.

[ACTIVITY] Weekly report for week 17

by Thomas Preudhomme

=== Work done during this GCC week === * stack-protector failure on GCC ARM: need feedback from community + prevent CSE of stack protector's guard first by adding some extra UNSPEC then instead by making all memory accesses involved volatile + write 2 monstro regex (251 & 377 characters respectively) to catch the bug on ARM, Thumb-2 and Thumb-1 + testing and will submit for review later today once I have all test results + discuss raising a CVE * Misc: + Arm meetings + Meeting with ST to discuss how to implement something akin to multilib + spec files for LLVM + Linary syncs + review of "Implement getConstraintRegister for ARM and AArch64" patch by Mikhail Maltsev === Plan for weeks up to 25 === * Paternity leave * Get stack-protector failure fix committed * DSGHACK-25 (Support arithmetic on FileCheck regex variable): finish patch * Start looking into LLVM SPEC optimizations Linaro tickets

[ACTIVITY] report week ending 27 Apr

by Peter Maydell

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.

=== Work done during this GCC week === * TCWG-1379 (stack-protector failure on GCC ARM): need feedback from community + reproduce on trunk and find out why it happens on ARM and not AArch64 or x86 + find potential issue for all targets as well, though less likely + find discrepencies between code and documentation and wondered if code is not overly zealous in some case * 2 days doing Arm handover & meetings === Plan for next week (week 12) === * Progress on stack-protector failure * Support arithmetic on FileCheck regex variable: finish patch

by Peter Maydell

Progress: * VIRT-65 [QEMU upstream maintainership] + sent another patch related to linux-user signal frames (a wrinkle I had thought had no effect with SVE disabled turns out to be relevant in the no-SVE case too) + testing and applying patches for 2.12 rc4 + code review: - latest spin of the SMMUv3 emulation patches - some last-minute fixes to our softfloat refactoring - memory barrier handling in the 32-bit arm TCG backend was broken + tracked down a zephyr test failure on QEMU as the same bug in the Zephyr timer device driver as the one I reported 6 months ago... + sent a patch fixing linux-user emulation of getdents syscall for 64-bit guest on 32-bit host + sent a patchset that removes the long-standing "only 4 serial ports" limit in QEMU (various Arm boards really have 5 or 6) + some patches fixing errors in arm boards that don't properly register all their RAM regions for migration thanks -- PMM

Note1: working for Linaro every other week === Issues === * IT issues made me loose 1 day of work === Work done during this LLVM+GCC week === * LLVM PR34170 (crashes with inline asm with double output operand in GPR): internal review + improved patch to also support case with several output operands -> had to choose to relax test a bit to not put expectation on register allocator * Support arithmetic on FileCheck regex variables: in progress + an attempt to be able to express that 2 registers are related by some arithmetic expression (eg. vmov dY, rX, rX+1), seems doable Upstream work on Arm GCC side: cmse_nonsecure_caller return wrong answer: backported to GCC 7 * __builtin_arm_set_fpscr crashes with literal values input: committed to trunk, backport oked + do more testing and prepare backport to GCC 6 & 7 * PR85344 (GCC fails constraint check on valid code): in progress + 2 prototype patches done but inconclusive result + pondering what should be the expect behaviour + investigating the extent of the problem -> both immediate and register constraints can be surprising === Plan for next week (week 12) === * Investigate stack-protector failure with Linaro GCC 7 toolchains * DSGHACK-25 (Support arithmetic on FileCheck regex variable): finish patch === Planned leave === * 28th April -> 29th May Sabbatical (Trip to France, then China, then France again)

[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
