================
Comment at: llvm/cmake/modules/HandleLLVMOptions.cmake:321
     # relocations due to -fno-pic.
-    if (CMAKE_COMPILER_IS_GNUCXX OR (CMAKE_CXX_COMPILER_ID MATCHES "Clang" AND
-        CMAKE_CXX_COMPILER_VERSION GREATER_EQUAL 13))
+    # GCC for SystemZ: Enable `-fno-semantic-interposition` when using
+    # GCC version >= 11. Old versions of GCC seems to have bugs.
----------------
GCC<11 has bugs on SystemZ, so don't use the option for older GCC.
