Progress: [short week, 3 days] * VIRT-65 [QEMU upstream maintainership] + code review - RTH's FP16 bugfixing patchset - Alex's float-to-float conversion patchset - fixes to SD card CRC checking - various minor linux-user cleanups * VIRT-164 [improve Cortex-M emulation] + working on emulation of Memory Protection Controller: have a working prototype that needs a few loose ends tidied up 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] [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
