--- Comment #12 from David Abdurachmanov <david.abdurachmanov at gmail dot com> --- I decided to re-enable -Os for OpenLoops. Then use powerful hardware with 32-physical-cores (x86_64) and 0.5TB of RAM to see if I could get lucky. Fired up QEMU user mode with Fedora for AArch64 chroot for compiling. It did resolve some of failures, but not everything. I have seen processes going as far as 25+GB of RSS and taking hours to finish. This is the reason package is compiled with -O0.
