Fixing the memory leak bug Full implement of the Li Convert Li to my own asm langues, opcode move reg,imm Left todo is add the anyalying process and converting process, after that we can translate our frist public pe file for ppc to intel with one opcode, it must be Li svn path=/trunk/; revision=25447
