by Christophe Lyon

== 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. Updated cmse-15.c test. Analyzing / bisecting other failures. - Sent fixes to MVE tests to avoid failures on arm-linux-gnueabi toolchains - Updated a few bugzilla entries about cortex-m issues * misc: - infra fixes / troubleshooting / reviews == Next == * FDPIC GDB * GCC/cortex-M

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

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

by Christophe Lyon

== 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

by Richard Henderson

[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~
