# This is a bazelrc file, documented in https://bazel.build/run/bazelrc and
# specifies default flags when BoringSSL is the root project. It has no effect
# on downstream projects, which define their own toolchains and configs.

# See https://bazel.build/run/bazelrc#enable_platform_specific_config.
# This expands to --config=osname which, in turn, expands to the options
# specified below.

# Bazel has no abstractions for setting C++ versions and expects the root
# project to use the compiler-specific options for their toolchains. (Bazel only
# wants the root to set the C++ version for the sake of projects like Abseil
# whose ABI depends on the C++ version.)
