However, macOS Safari and WebKit binaries still need to be able to run on the open source XNU, albeit without JIT. However, ExecutableAllocator::disableJIT() is still trying to allocated JIT memory if the JIT entitlement is present (which is defined by the WebKit binary, not the kernel), and currently, will assert that the allocation succeeds. We need to skip this allocation and assertion when running on open source XNU because the allocation is not necessary, and the assertion is invalid for the open source kernel and will fail every time. 1963093 1 mark.lam 2023-06-22 11:09:42 -0700 rdar://111170164 1963101 2 mark.lam 2023-06-22 11:29:48 -0700 Pull request: https://github.com/WebKit/WebKit/pull/15204 1963179 3 ews-feeder 2023-06-22 17:49:28 -0700 Committed 265435@main (6063bc484b4f): <https://commits.webkit.org/265435@main> Reviewed commits have been landed.
