[Lldb-commits] [lldb] [lldb][test][FreeBSD] Narrow vectorcall xfail to x86 platforms (PR #84024)

[David Spickett via lldb-commits]

https://github.com/DavidSpickett created https://github.com/llvm/llvm-project/pull/84024

vectorcall only works on x86 https://clang.llvm.org/docs/AttributeReference.html#vectorcall so elsewhere it fails to compile. Which is expected on AArch64 for example so is treated as a pass.
