+# Wrapper script to remove clang compiler flags rejected by clang-tidy.
+# Inputs:
+#  Environment:
+#   CLANG_TIDY: path to the real clang-tidy program
+
+# clang-tidy doesn't recognize every flag that clang compiler does.
+# It gives clang-diagnostic-unused-command-line-argument warnings
+# to -Wa,* flags.
+# The -flto flags caused clang-tidy to ignore the -I flags,
+# see https://bugs.llvm.org/show_bug.cgi?id=38332.
+# -fsanitize and -fwhole-program-vtables need -flto.
