-# 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.
