== Progress == * GCC upstream validation: - reported a couple of failures/regressions * GCC: - Committed a few fixes to MVE/CDE tests to avoid failures on arm-linux-gnueabi toolchains - Sent a few more testcases fixes - PR94538 (pure-code/M23): Let Wilco handle it since he has more testcases - Looked at Linaro bug #5614, and forwarded it for upstream discussion as PR94743 (IRQ handler and Neon registers) * FDPIC/GDB: - rebased gdbserver patches, it still crashes at runtime. Code size bigger than my last attempt with gdb-8.x. - tried to link it statically, but that fails because of multiple defs in uclibc. * misc: - infra fixes / troubleshooting / reviews - lots of disruptions == Next == * FDPIC GDB * GCC/cortex-M

Re: buildbot failure in LLVM on clang-cmake-armv8-lld

by David Blaikie

Looks like there might be something wrong with this buildbot? (none of the commits seem to have changed lnt - or maybe lnt isn't monitored/blamed in the buildbot config?)

[ACTIVITY] 2 weeks ending 19 Apr 2020

by Richard Henderson

Short weeks around Easter. [VIRT-349 # QEMU SVE2 Support ] Lots of progress on insn implementation. Several patches from Stephen Long merged. He's coming up to speed nicely. Some good review from Laurent Desnogues. Spent some time writing a version of strspn for Arm optimized-routines, as a way of testing the NMATCH instruction. Found bugs in the tcg optimizer instead. Still in the process of rebasing the branch upon those fixes, and upon patch review from Peter. [VIRT-327 # Richard's upstream QEMU work ] Couple of patches for 5.0. [GCC] Posted v4 of aarch64 cmpti patch set. r~

[ACTIVITY] report week ending 17 Apr

by Peter Maydell

(short week, 3 days) Progress: * VIRT-65 [QEMU upstream maintainership] - getting rc3 out of the door, including sorting out some last minute bug fixes. As usual, we hope not to need an rc4 but I expect we will. - code review; a two-day blitz has got my to-review queue down to a slightly more manageable size... + rth's series refactoring SVE load/store implementation + Guenter's i.MX watchdog support series + brief pass over raspi USB host controller emulation series + patch adding /secure-chosen/kaslr-seed to the virt dtb + the Greensocs/Xilinx clock framework patchset [including doing an editing pass on the docs] thanks -- PMM

How to use 'runtime-linaro-...' and 'sysroot-linaro-...' archives ?

by Константин Аладышев

Hello! I know, this is probably a very stupid question, but I couldn't find an answer for it. On the page https://releases.linaro.org/components/toolchain/binaries/latest-5/arm-linu… there are 3 major download components: gcc/sysroot/runtime. I download 'gcc', add 'gcc-linaro-.../bin' to my PATH and cross compile my apps. On my target system, I need 'libc', and it is present in the 'sysroot-linaro-...'. Do I need to copy all of the contents of 'sysroot-linaro-...' folder to my target? 'linaro-sysroot' folder is kinda big. 'libc.so' library is 13MB. If there is a way to decrease its size, if I want to use Linaro compiled programs on an embedded target? And what is a purpose of 'runtime-linaro-..." component?
