DependableSystemsLab / LLFI

LLFI is an LLVM based fault injection tool, that injects faults into the LLVM IR of the application source code. The faults can be injected into specific program points, and the effect can be easily tracked back to the source code. Please refer to the paper below. NOTE: If you publish a paper using LLFI, please add it to PaperLLFI.bib

Error with using customRegSelector #112

Closed saber1994 closed 6 years ago

saber1994 commented 6 years ago

I want to use a customRegSelector and I faced a error when running command "instrument": My input.yaml is below:

compileOption:
   instSelMethod:
     - customInstselector:
          include:
            - onlymain         
  regSelMethod: customregselector
  customRegSelector: onlyconstint

  includeInjectionTrace: 
    - forward
    - backward

  tracingPropagation: True # trace dynamic instruction values.

  tracingPropagationOption:
    maxTrace: 250 # max number of instructions to trace during fault injection run
    debugTrace: True/False
    generateCDFG: True

 runOption:
    - run:
       numOfRuns: 3
       fi_type: bitflip

The error message is below:

It's difficult for us to reproduce this error without further details of your setup and benchmark. Did your installation of LLFI pass the regression tests ? if not, I suggest checking that first.
