-# "Fast Half Float Conversions" by Jeroen van der Zijp, Nov 2008
-#
-# The table contents have been slightly changed so that the exponent
-# bias is now in the exponent table instead of the mantissa table (mostly
-# for cosmetic reasons, and because it theoretically allows a variant
-# that flushes denormal to zero but uses a mantissa table with 24-bit
-# entries).
-#
-# The tables are also constructed slightly differently.
-#
-
-# Note that using a 64K * 4 table is a terrible idea since it will not fit
-# in the L1 cache and will massively pollute the L2 cache as well
-#
-# These should instead fit in the L1 cache.
-#
-# TODO: we could use a denormal bias table instead of the mantissa/offset
-# tables: this would reduce the L1 cache usage from 8704 to 2304 bytes
-# but would involve more computation
-#
-# Note however that if denormals are never encountered, the L1 cache usage
-# is only about 4608 bytes anyway.
