Hello Filip Kastl,
Sorry for the delay in responding to your message.

I got an automated mail about this GCC regression related to one of my commits.
https://linaro.atlassian.net/browse/GNU-1578
The mail itself mentioned only a testsuite regression. I fixed that. However, this was also linked in the mail:
https://ci.linaro.org/job/tcwg_bootstrap_build--master-arm-bootstrap_profile...
That looks like a different regression. As far as I can tell, `make profiledbootstrap` is failing on arm. I have only very limited access to arm machines. I tried to reproduce this on an Aarch64 machine and didn't succeed.
I've been trying to reproduce this problem, but it's not so simple. I wasn't able to reproduce it on a Graviton 3 machine with armv8l userspace, but succeeded on a Mt Jade machine with armv8l. But then only using our CI's scripts not when building manually (even if I'm using the same configure and make commands). I'm still digging into it.
Could you check that this regression is still present on current trunk and/or help me reproduce it?
I can't say whether trunk has this regression because I'm hitting another issue when building this compiler configuration on trunk gimple-match-6.cc:
/path/to/gcc.git/./prev-gcc/xg++ <tons of options> -o gimple-match-6.o gimple-match-6.cc /tmp/ccR6Swju.s: Assembler messages: /tmp/ccR6Swju.s:241032: Error: conditional branch out of range /tmp/ccR6Swju.s:241115: Error: conditional branch out of range /tmp/ccR6Swju.s:254075: Error: conditional branch out of range /tmp/ccR6Swju.s:254339: Error: conditional branch out of range /tmp/ccR6Swju.s:254459: Error: conditional branch out of range
I'll see if I can find a recent commit without this problem.
Btw the "Instructions to reproduce the build" link doesn't work for me. I get "Request is not authorized". https://git-us.linaro.org/toolchain/ci/interesting-commits.git/plain/gcc/sha...
We're in the middle of migrating our CI's git repos to GitLab. Maybe that is related to your problem, but I have to check.
