PR #140758 added the undocumented
/arm64hazardfreeMSVC linker flag to work around a test failure where LLVM generated code that would trip a hazard in an outdated ARM processor.Adding this flag caused issues with LLD, as it doesn't recognize it.
Rethinking the issue, using the undocumented flag seems like the incorrect solution: there's no guarantee that the flag won't be removed in the future, or change its meaning.
Instead, I've disabled the problematic test for Arm64 Windows and have filed a bug with the MSVC team to have the check removed: https://developercommunity.microsoft.com/t/Remove-checking-for-and-fixing-Cortex-A/10905134
