# 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'],
