I have some questions. please let me know my understanding is correct ? 1) i386-tdep.c is the one which has been done for record-replay. which basically takes care of disassembling insns... but I see some code regarding MMX and x87FPU already available. may I know exactly, what support is missing ? 2) I also see SSE XMM0-XMM7 register stuufs in teh code too. we need to support XMM (SSE) or it is already done. please clarify above two points. please clarify to what support is missing and what is expected ? Anyway, I am going through i386-tdep.c thoroughly to understand it fully. Regards, Oza.
