LLFI-Quick-Start

0. Change directory to fault injection base

# example
cd perInstFI                            # per-Instruction FI
cd randomFI                             # random FI

1. Compile sqrt.c to readable IR:

clang -emit-llvm -S *.c

2. Instrument IR-level codes to readable IR:

instrument --readable sqrt.ll

3. Profile: run a fault-free IR:

profile ./llfi/sqrt-profiling.exe

4. Fault Injection: run a fault-injected IR:

injectfault ./llfi/sqrt-faultinjection.exe

5. Analyze FI results:

python3 measure.py
