-# This file is meant to be included to set clang-specific compiler flags.
-# To use this the following variable can be defined:
-#   clang_warning_flags:       list: Compiler flags to pass to clang.
-#   clang_warning_flags_unset: list: Compiler flags to not pass to clang.
-#
-# Only use this in third-party code. In chromium_code, fix your code to not
-# warn instead!
-#
-# Note that the gypi file is included in target_defaults, so it does not need
-# to be explicitly included.
-#
-# Warning flags set by this will be used on all platforms. If you want to set
-# warning flags on only some platforms, you have to do so manually.
-#
-# To use this, create a gyp target with the following form:
-# {
-#   'target_name': 'my_target',
-#   'variables': {
-#     'clang_warning_flags': ['-Wno-awesome-warning'],
-#     'clang_warning_flags_unset': ['-Wpreviously-set-flag'],
-#   }
-# }
