rdar://174265947 Recent changes to libpas (307140@main, 294862@main) have changed PAS_MIN_OBJECTS_PER_PAGE from 6 to 10, then 11, as well as changing the page-size of medium-bitfit pages from 128k to 512k. The first of those patches broke some libpas tests (particularly in ThingyAndUtilityHeapAllocationTests.cpp and IsoHeapPartialAndBaselineTests.cpp) which check for these page boundaries, which has masked the effect of further changes from subsequent patches. These tests should be re-baselined so that we can get back to green. The size-boundaries as of 310711@main are bmalloc: ``` Small Segregated: 1472B Medium Segregated: 11776B Small Bitfit: 1456B Medium Bitfit: 32768B Marge Bitfit : 380928B ``` jit: ``` Small Segregated: 1488B Small Bitfit: 1012B Medium Bitfit : 64768B ``` utility: ``` Small Segregated: 1400B ```
