[PATCH] D97504: [llvm-exegesis] Disable the LBR check on AMD

[Ondrej Sykora via Phabricator via llvm-commits]

ondrasej added inline comments.


================
Comment at: llvm/lib/Support/Host.cpp:507
+  if (!isCpuIdSupported())
+    return VendorSignatures::UNKNOWN;
+
----------------
As noted in the other patch - when MaxLeaf is nullptr we should set it to zero if this return statement is used.

Otherwise, it will keep its default value and for the caller it will be impossible to distinguish this branch from the return statement on line 520.
