# bazel enables the --ffunction-sections, --gc-sections flags used to remove dead code by default
# on Linux opt builds. Enable the equivalent macOS flag -Wl,-dead_strip here to work around bazel
# idiosyncrasies.
# Note that the flag is defined for all non-debug builds of kj_test() and wd_cc_binary() on mac as
# it surprisingly appears to be faster, perhaps because the linker generates and writes binaries
# with much fewer symbols. This also helps reduce local and CI disk usage. If needed, dead code
# stripping can be limited to optimized builds.
