llvm/**/*X86* seems like it’ll grab too much, if I’m following the pattern correctly. For example, it would match `llvm/test/tools/llvm-objdump/X86, and many of the tests there have little to do with x86, other than that they need a valid disassembly target to demonstrate generic features (e.g. the --start-address flag) in llvm-objdump.
More generally, those sort of patterns may match similar places for other targets in the test directories.
