26: * machine, although it might work on other i386 Unices.
27: * This is supposed to speed up application programs. It will not work very
28: * well for hardware bangers like games and demos, in fact it will be much
29: * slower. It can also be slower for some applications and/or benchmarks.
30: * It needs a lot of tuning. Please let me know your results with this.
31: * The second define, RELY_ON_LOADSEG_DETECTION, decides how the compiler
32: * tries to detect self-modifying code. If it is not set, the first bytes
33: * of every compiled routine are used as checksum before executing the
34: * routine. If it is set, the UAE filesystem will perform some checks to
35: * detect whether an executable is being loaded. This is less reliable
36: * (it won't work if you don't use the harddisk emulation, so don't try to
37: * use floppies or even the RAM disk), but much faster.
