Hello Tamar,
It looks like this failure happens because qemu-aarch64 segfaults when trying to run the testcase binary:
Running on qemu: timeout -k 30s 330s setarch x86_64 -R qemu-aarch64 -cpu any -R 0 -L /home/tcwg-buildslave/workspace/tcwg_gnu_1/abe/builds/destdir/x86_64-pc-linux-gnu/aarch64-linux-gnu/libc ./mask_struct_load_3_run.exe spawn [open ...] timeout: the monitored command dumped core FAIL: gcc.target/aarch64/sve/mask_struct_load_3_run.c execution test
Which would be a QEMU bug. I'm working on reproducing it and will report there if appropriate.
However, our CI also found some size and performance regressions with this commit, as detailed in https://linaro.atlassian.net/browse/GNU-1040:
- tcwg_bmk-code_size-cpu2017fast - gnu-aarch64-master-O2: grew in size by 3% - 508.namd_r - gnu-aarch64-master-O2_LTO: grew in size by 2% - 508.namd_r
