Broken libcxx-libcxxabi-libunwind bots due to Filesystem tests

by Louis Dionne

Hi, It looks like the following bots assigned to you started failing recently: http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv7-linux http://lab.llvm.org:8011/builders/libcxx-libcxxabi-libunwind-armv7-linux-no… The failing tests are all filesystem tests: FAIL: libc++::assign.pass.cpp FAIL: libc++::path.pass.cpp FAIL: libc++::replace_filename.pass.cpp FAIL: libc++::refresh.pass.cpp FAIL: libc++::file_size.pass.cpp FAIL: libc++::file_type_obs.pass.cpp FAIL: libc++::hard_link_count.pass.cpp FAIL: libc++::last_write_time.pass.cpp FAIL: libc++::ctor.pass.cpp FAIL: libc++::ctor.pass.cpp FAIL: libc++::increment.pass.cpp FAIL: libc++::exists.pass.cpp FAIL: libc++::is_block_file.pass.cpp FAIL: libc++::is_character_file.pass.cpp FAIL: libc++::is_directory.pass.cpp FAIL: libc++::is_empty.pass.cpp FAIL: libc++::is_fifo.pass.cpp FAIL: libc++::is_other.pass.cpp FAIL: libc++::is_regular_file.pass.cpp FAIL: libc++::is_socket.pass.cpp Having seen some of these issues before, I strongly suspect this is due to the fact that your builder is running as root. Libc++'s filesystem tests are known to fail when run as root, because some of them need to check for failure to access some files for which there's no permission. This doesn't seem to work when run as root. Can you work with us to resolve this issue? Thanks, Louis

== Progress == * GCC upstream validation: - reported a couple of failures/regressions * GCC: - comparing testsuite results for cortex-m3 and cortex-m33 with cortex-a9 to check what cortex-M problem there are. Spent a long time isolating a regression in CMSE tests. Filed PR94445 which was then quickly fixed by upstream in ICF optimization. * misc: - infra fixes / troubleshooting / reviews == Next == * FDPIC GDB * GCC/cortex-M

[VIRT-349 # QEMU SVE2 Support ] Met with Qualcomm on Friday to discuss sharing the development work, and help start bringing their new-hire, Stephen Long, up to speed on qemu. Gave Stephen generic qemu development pointers, and a simple set of SVE2 instruction on which to wet his feet. [VIRT-327 # Richard's upstream QEMU work ] Better constant propagation and allocation for TCG. Worked on probe_guest_base as a follow-up to some of the work Alex was doing wrt init_guest_space. Misc patch review for 5.0. [GCC] Posted v3 of aarch64 cmpti patch set. r~

Progress: * VIRT-65 [QEMU upstream maintainership] - More freeze related wrangling... * VIRT-241 [QEMU ISA Support for A-profile] - pushed the ARMv8.2-TTS2UXN patchset out to the mailing list - found and fixed a bug in our PAN support where we were making PSTATE.PAN forbid execute access, not just data access * VIRT-364 [QEMU support for ARMv8.1-M extensions] - Started on some preliminary refactoring that we'll need so we can more conveniently modify the decoder for v8.1M: converting the A32/T32 Neon decoder to use decodetree. I've done the "post-v8.0 extensions" instructions, and started on the loads-and-stores. thanks -- PMM
