[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?

Failing libcxx-libcxxabi-libunwind bots

by Louis Dionne

Hi, It looks like several bots assigned to you started failing after e6a39f00e8d0 was committed: http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv8-linux-no… http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv8-linux http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-aarch64-linux http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-aarch64-linux-… They all fail on the test libcxx/test/libcxx/modules/stds_include.sh.cpp with the following error: <...>/libcxx/test/libcxx/modules/stds_include.sh.cpp:28:2: fatal error: file '<...>/libcxx/include/type_traits' has been modified since the module file '<TMP>/ModuleCache/1E92AHT/std-1V9DLRO.pcm' was built #include <vector> ^ <...>/libcxx/test/libcxx/modules/stds_include.sh.cpp:28:2: note: please rebuild precompiled header '<TMP>/ModuleCache/1E92AHT/std-1V9DLRO.pcm' 1 error generated. Our other bots are not failing, so I very strongly suspect this is not because of the change itself, but rather some weirdness in your bot configuration. For that reason, I will *not* revert the change (that would likely not improve the situation anyway). Can you please collaborate with us to understand and fix the issue? Thanks, Louis
