# rules
#
# NOTE: the '.c' files are pregenerated sources, and must be compiled with
# -O1 optimization. that is why the rule for .c files is a bit different.
# why should it be compiled with O1? it is numerical code that is generated
# by fbuild. O1 optimization is used to preserve the operation orders that
# were discovered by fbuild to be the fastest on that platform. believe it or
# not, O2 makes this code run much slower for most compilers.
