# Release configs are defined in reflease_config_map files, which map
|
|
# the short name (e.g. -next) used in lunch to the starlark files
|
|
# defining the build flag values.
|
|
#
|
|
# (If you're thinking about aconfig flags, there is one build flag,
|
|
# RELEASE_ACONFIG_VALUE_SETS, that sets which aconfig_value_set
|
|
# module to use to set the aconfig flag values.)
|
|
#
|
|
# The short release config names *can* appear multiple times, to allow
|
|
# for AOSP and vendor specific flags under the same name, but the
|
|
# individual flag values must appear in exactly one config. Vendor
|
|
# does not override AOSP, or anything like that. This is because
|
|
# vendor code usually includes prebuilts, and having vendor compile
|
|
# with different flags from AOSP increases the likelihood of flag
|
|
# mismatch.
|
|
|
|
# Do this first, because we're going to unset TARGET_RELEASE before
|
|
# including anyone, so they don't start making conditionals based on it.
|
|
# This logic is in make because starlark doesn't understand optional
|
|
# vendor files.
|
|
|
|
# If this is a google source tree, restrict it to only the one file
|
|
# which has OWNERS control. If it isn't let others define their own.
