1. Build SVF

Please refer to SVF setup

2. Compile your project into LLVM bc files

clang -c -emit-llvm -g example.c -o example.bc

To compile a complicated real-world project you may wish to use WLLVM guide to install it.

Compile your example.c into an executable and extract it into example.bc

'wllvm example.c -c -emit-llvm -g -o example.bc

3. Run SVF's memory leak detector on the generated bc file

cd SVF
. ./setup
saber -leak -stat=false example.bc

4. The printed memory leak results when analyzing this test case

	 PartialLeak : memory allocation at : (ln: 23 fl: sp1.c)
		 conditional free path: 
		  --> (ln: 12 fl: sp1.c)
