Recompile a x86 code with LLVM to some faster one x86

Question

Is it possible to run LLVM compiler with input of x86 32bit code? There is a huge algorithm which I have no source code and I want to make it run faster on the same hardware. Ca

Answer 1

From what I know, disassembling x86 code 100% correctly is impossible. As data and code is intermingled and also due to variable length instructions. The only way to properly disassemble is to interpret it on the fly.
