llvm dev - Dec 2012 - [LLVMdev] how to get and modify a local variable's value through executionEngine?

hi Óscar Fuentes,
i am new to llvm, so i still have several questions. thanks for you help.
(1)what is SSA form(static single assignment)?
(2)how to traverse the basic blocks? if the module is gained by parser, what
will the basic blocks contain?
i will be on the line, thank you very much

Yes.

Once the LLVM IR bytecode is loaded (or the LLVM assembler is parsed)
you have the same C++ objects that you previously generated when you
emitted the IR from your compiler. As for traversing those C++ objects
for examining the IR or transforming it, see

See http://www.llvm.org/docs/WritingAnLLVMPass.html

hi Óscar Fuentes ,
thanks for your reply, but there are still a lot of concepts i don't
understand. there seems to be some document to guide you but hard to
understand. can you show me some basic and easy to learn document or
websites?
thank you
