[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
