Hi there,
I can only locate the error message like "/tmp/cc4i9dn1.s:151930: Error: conditional branch out of range". But failed to reproduce this when cross build, is there anywhere to get the build option for reproducing?
Thanks.

It's not possible to do a profiledbootstrap via cross. It might be possible for the Linaro CI to extract the bad preprocessed source and share the options used to build it (options at least should be in the log) but that won't help if the compiler is miscompiled...
I see, this error may require bootstrap build. There is no aarch64 machine currently. Let me try to find one somewhere.

It seems the problem is even more tricky than "just" bootstrap: AFAICS the "bootstrap" builds passed, the "bootstrap_profiled" and "bootstrap_profiled_lto_lean" failed.
So, you need to configure with --enable-bootstrap and build with 'make profiledbootstrap'.
In addition, the problem occurs on arm targets, as opposed to aarch64, so the easiest for you is probably to start a container in aarch32 (aka arm) mode on an aarch64 machine (provided its CPU supports that mode). Once in the container, you don't need to use --target XXX --with-arch=YYY configure options.
Good luck,
Christophe

You could use one of aarch64 machines in GCC's compiler farm. If that doesn't work -- send me a private email and I'll create a docker container for you on one of Linaro machines.

No response from the compiler farm.
But due to some more discussion for the simplification on SAT, this patch is reverted. Thus I bet this build error should be gone up to a point. Please feel free to ping me if any issues.
