introspec	d5d788946e	Added an option for unrolling long match copying ... Usually useless and costing +57 bytes, this option can bring dramatic performance improvements on very compressible data dominated by long matches	2019-10-22 20:11:46 +01:00
introspec	495a12216f	-1 byte ... Very slightly faster too	2019-10-11 00:23:43 +01:00
introspec	566e3a94e8	+0.2% speed ... also, added an option to unroll LDIR for longer matches (which adds 38 bytes, but can be significantly faster for files with many long matches)	2019-10-10 22:50:23 +01:00
