| # 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. |
