# 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'],
# }
# }
{
'variables': {
'clang_warning_flags_unset%': [], # Provide a default value.
},
'conditions': [
['clang==1', {
# This uses >@ instead of @< to also see clang_warning_flags set in
# targets directly, not just the clang_warning_flags in target_defaults.
