* Some flags are accepted by clang but not clang-tidy. They could cause the diagnostic-unused-command-line-argument warning. Flag -flto messed up the -I flags. * Add clang-diagnostic-unused-command-line-argument to default clang-tidy checks. * Move CLANG_TIDY_UNKNOWN_CFLAGS to build/make/core/clang/tidy.mk. Bug: 111850071 Bug: 111885396 Test: build with WITH_TIDY=1 Change-Id: Iabeeb27715acf83ef6aafe3e77206b9a01a0d889

# 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.
