Emmanuel Marty	8551c3ff8a	Merge pull request #35 from MobyGamer/decompressor/8086_speed_jumptable ... Rewrite 8088 jumptable decompressor for maximum speed	2019-10-27 10:28:48 +01:00
mobygamer	30192238ea	Rewrite 8088 jumptable decompressor for maximum speed ... This is a rewrite of LZSA1JMP.ASM to use a 256-element jumptable, which allows the code to handle all of the hot paths (common cases) without any branching. This not only reduces branches (which are very costly on x86) to a bare minimum, but also grants us foreknowledge in a decode path of what steps can be skipped. The new code is 12.7% faster than the old code, and assembles to less than 3K of object code and data.	2019-10-26 23:34:24 -05:00

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
