| # 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). |
