Hi , Is there any way to modify code like adding junk code or mess up the order of a bunch of codes(in same basic block) which is no dependency? I saw some options like -dce -deadargelim for 'opt' , but what I want is to reverse to do it. I mean adding some dead code or junk code. Actually what I want is to implement a ploymorphic engine. Coud I do those by using llvm? Thanks. Qiuyu

..., modifying and adding to the LLVM IR is easy. Please read the > programmers manual for more info: > > http://llvm.org/docs/ProgrammersManual.html > > For example, "Creating and inserting new Instructions" might be useful: > http://llvm.org/docs/ProgrammersManual.html#schanges_creating >
