Use these whenever possible. - - src_gas sources converted for portable gcc/gas syntax - src_masm sources converted for portable masm/tasm/wasm syntax - src_nasm sources converted for portable nasm syntax - - src assembler sources (you need the OpenSource nasm assembler) - - obj pre-assembled object files - -Also look 'src_XXX/all/asm_all.asm' which contains all assembler -functions conveniently arranged into a single file. - - -Notes: -====== - -- The assembler sources are designed for a flat 32-bit memory model - running in protected mode - they should work with all i386 - 32-bit compilers around. - -- All functions expect a 'cdecl' (C stack based) calling convention. - The function return value will be placed into 'eax'. - All other registers are preserved. - -- Prototypes for the assembler functions can be found in <lzo/lzo_asm.h>. - -- For reasons of speed all fast assembler decompressors (having '_fast' - in their name) can access (write to) up to 3 bytes past the end of - the decompressed (output) block. Data past the end of the compressed - (input) block is never accessed (read from). - [ technical note: because data is transferred in 32-bit units ] - -- Finally you should test if the assembler versions are actually faster - than the C version on your machine - some compilers can do a very good - optimization job, and they also can optimize the code for a specific - processor type. - |
