#
#
# NOTE on -ffast-math
#
# First, breaks strict IEEE compliance, e.g. allows re-ordering of
# instructions to a mathematical equivalent, which may not be IEEE
# floating-point equivalent.
#
# Second, disables setting errno after single-instruction math functions,
# avoiding a write to a thread-local variable (can produce 100% speedup on
# certain architectures).
#
# Third, assumes finite math only, meaning no checks for NaN (or 0) are
# made where they would normally be. It is assumed these values will never
# appear.
#
# Fourth, enables reciprocal approximations for division and reciprocal
# square root.
#
# Fifth, disables signed zero (even if the compile target supports it)
# and rounding math, which enables optimizations e.g. constant folding.
#
# Sixth, generates code assuming no hardware interrupts occur in math
# due to signal()/trap(). If these cannot be disabled on the compile
# target and consequently occur, they will not be handled.
