Description
the option --stackmap-version with any int value but not default 3 will crash.
It reports Unsupported stackmap version! error, but some segmentation fault might occur which aslo triggers the crash backtrace.
Crash has be reproduced in llvm-18.1.2 and llvm-16.
Reproduced with:
/mnt/llvm-project-llvmorg-18.1.2/build/bin/llc --stackmap-version=13 /mnt/data/acpi_listen.bc -o /mnt/data/acpi_listen.s
trace:
Unsupported stackmap version!
UNREACHABLE executed at /mnt/llvm-project-llvmorg-18.1.2/llvm/lib/CodeGen/StackMaps.cpp:168!
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
