# The library code is faster static than shared on some systems, so do
# tuning and measuring with static, since users who care about maximizing
# speed will be using that.  speed-dynamic exists to show the difference.
#
# On Solaris 8, gcc 2.95.2 -static is somehow broken (it creates executables
# that immediately seg fault), so -all-static is not used.  The only thing
# -all-static does is make libc static linked as well as libmpir, and that
# makes a difference only when measuring malloc and friends in the speed
# program.  This can always be forced with "make speed_LDFLAGS=-all-static
# ..." if desired, see tune/README.

#
# mpn/generic/tdiv_qr.c uses mpn_divrem_1 and mpn_divrem_2, but only for 1
# and 2 limb divisors, which are never used during tuning, so it doesn't
# matter whether it picks up a tuned or untuned version of those.
#
# divrem_1 and mod_1 are recompiled renamed to "_tune" to avoid a linking
# problem.  If a native divrem_1 provides an mpn_divrem_1c entrypoint then
# common.c will want that, but the generic divrem_1 doesn't provide it,
# likewise for mod_1.  The simplest way around this is to have the tune
# build versions renamed suitably.
#
# FIXME: Would like say mul_n.c to depend on $(top_builddir)/mul_n.c so the
# recompiled object will be rebuilt if that file changes.
