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
- tcwg_bmk-code_size-spec2k6
- gnu-aarch64-master-O2: grew in size by 2% - 447.dealII
- gnu-aarch64-master-Os: grew in size by 2% - 456.hmmer
- tcwg_bmk-code_speed-cpu2017rate
- gnu-aarch64-master-O2: slowed down by 5% - 519.lbm_r
- gnu-aarch64-master-O3: slowed down by 5% - 519.lbm_r
- tcwg_bmk-fujitsu_speed-cpu2017speed
- gnu-aarch64-master-O2: slowed down by 19% - 644.nab_s:[.] exp@@GLIBC_2.29
