hi,all
* I want to translate ISA of LLVM to another kind of ISA one by
one,for example,I write a loader which can load ".o" file which
is generated by "llvm-gcc abc.c -emit-llvm -c",and then I want
to analysis it and translate it to another kind of ISA
dinamically!Unforunately,I have not found any binary encoding
information about LLVM's ISA,so it's impossible for me to
implement it now.
*
* Who can give me some instructions on it? Thanks!
