# Check that llvm-mca doesn't crash when analyzing this block of code.

# This test is related to PR38575.
# The crash was indirectly cause by an incorrectly truncation of a processor
# resource mask value (an uint64_t) to int value.
# The problem can only be observed on targets that declare more than 32
# resources (like exynos-m3).
