On Darwin, we want to limit the parallelism during test execution for sanitizer tests that use shadow memory. The reason is explained by this existing comment: > Only run up to 3 processes that require shadow memory simultaneously > on 64-bit Darwin. Using more scales badly and hogs the system due to > inefficient handling of large mmap'd regions (terabytes) by the > kernel. Previously we detected 3 cases: * on-device: limit to 1 process * 64-bit: macOS & simulators, limit to 3 processes * others (32-bit): no limitation We checked for the 64-bit case like this: `if arch in ['x86_64', 'x86_64h']` which misses macOS running on AS. Additionally, we don't care about 32-bit anymore, so I've simplified this to 2 cases: on-device and everything else. Differential Revision: https://reviews.llvm.org/D122751 |
