Description
The option --regalloc-enable-priority-advisor and --regalloc-priority-interactive-channel-base cooperate to crash.
The value of --regalloc-enable-priority-advisor should be release, then it requires option --regalloc-priority-interactive-channel-base.
The value of --regalloc-priority-interactive-channel-base can be any inexistent string path, and it will crash due to Segmentation fault.
Crash has be reproduced in llvm-18.1.2.
Reproduced with:
/mnt/llvm-project-llvmorg-18.1.2/build/bin/llc --regalloc-enable-priority-advisor=release --regalloc-priority-interactive-channel-base=foo /mnt/data/acpi_listen.bc -o /mnt/data/acpi_listen.s
