#
# This Makefile builds the upb library as well as associated tests, tools, and
# language extensions.
#
# It does not use autoconf/automake/libtool in order to stay lightweight and
# avoid the need for running ./configure.
#
# Summary of compiler flags you may want to use:
#
# * -UNDEBUG: enables assertions() (makes binary larger and slower)
# * -O0: disable optimizations
# * -g: enable debug symbols
# * -fomit-frame-pointer: makes code smaller and faster by freeing up a reg.
#
# Threading:
# * -DUPB_THREAD_UNSAFE: remove all thread-safety.
