Is there any way to execute linux commands in llvm pass and parse the objdump in it.

For example in python we can do as follows:

os.system('gcc example.c -o example') 
os.system('objdump -o example > parsed.txt')

and parse it by using regular expression.So, similarly can we do it in llvm pass as well?

  • You could call out to the system using any normal C/C++ system programming tools, but that would probably be considered "weird". What are you actually trying to accomplish? Commented Dec 14, 2016 at 16:22
  • @echristo - It's for my project, already I have an llvm pass, so I have to create another llvm pass so that I can call system () to execute the old llvm pass from the new llvm pass and then parse the object file of it.So can i use getAnalysisUsage() to do this? Commented Dec 15, 2016 at 15:07
  • You should just add you new pass to the pass pipeline like you did with your previous pass. Commented Jan 3, 2017 at 6:35
