# The Full Debug Symbols (FDS) default for BUILD_FLAVOR == product
# builds is enabled with debug info files ZIP'ed to save space. For
# BUILD_FLAVOR != product builds, FDS is always enabled, after all a
# debug build without debug info isn't very useful.
# The ZIP_DEBUGINFO_FILES option only has meaning when FDS is enabled.
#
# If you invoke a build with FULL_DEBUG_SYMBOLS=0, then FDS will be
# disabled for a BUILD_FLAVOR == product build.
#
# Note: Use of a different variable name for the FDS override option
# versus the FDS enabled check is intentional (FULL_DEBUG_SYMBOLS
# versus ENABLE_FULL_DEBUG_SYMBOLS). For auto build systems that pass
# in options via environment variables, use of distinct variables
# prevents strange behaviours. For example, in a BUILD_FLAVOR !=
# product build, the FULL_DEBUG_SYMBOLS environment variable will be
# 0, but the ENABLE_FULL_DEBUG_SYMBOLS make variable will be 1. If
# the same variable name is used, then different values can be picked
# up by different parts of the build. Just to be clear, we only need
# two variable names because the incoming option value can be
# overridden in some situations, e.g., a BUILD_FLAVOR != product
# build.

# Due to the multiple sub-make processes that occur this logic gets
# executed multiple times. We reduce the noise by at least checking that
# BUILD_FLAVOR has been set.
