#
# This Makefile builds the upb library as well as associated tests, tools, and
# language extensions.
#
# It does not use autoconf/automake/libtool because I can't stomach all the
# cruft. If you're not compiling for gcc, you may have to change some of the
# options.
#
# Summary of compiler flags you may want to use:
#
# * -DNDEBUG: makes binary smaller and faster by removing sanity checks.
# * -O3: optimize for maximum speed
# * -fomit-frame-pointer: makes code smaller and faster by freeing up a reg.
#
# Threading:
# * -DUPB_USE_PTHREADS: configures upb to use pthreads r/w lock.
# * -DUPB_THREAD_UNSAFE: remove all thread-safety.
# * -pthread: required on GCC to enable pthreads (but what does it do?)
#
# Other:
# * -DUPB_UNALIGNED_READS_OK: makes code smaller, but not standard compliant
# Function to expand a wildcard pattern recursively.
