[LLVMdev] store the LLVM-bitcode from a pass

[RAAD B]

Hi Duncan,

thanks for the answer. But    "opt  -load  ..../Decorator.so -dec <prog.bc> new_prog.bc"
creates an invalid file. When i use "lli", i get "lli: error loading program 'new_prog.bc': Invalid bitcode signature"

I have done the followings:
1) used "opt  -p -load  ..../Decorator.so -dec <prog.bc> new_prog.bc"
2) copied the output from the screen and created the file "new_prog.s"
3) used "llvm-as   new_prog.s -o new_prog.bc"
4) and then  "lli   new_prog.bc"

And it works.

any idea?


thanks
Raad

  opt  -load  ..../Decorator.so -dec <prog.bc> new_prog.bc

Ciao,
