Hi, I'm trying to instrument llvm bytecodes using opt. I performed the following commands: llvm-gcc -g -emit-llvm test.c -c -o test.bc opt -insert-edge-profiling test.bc -o output.bc llc output.bc -o output.s gcc output.s -o test.out However, it can't find symbol llvm_start_edge_profiling. /tmp/ccw7GH4c.o: In function `main': /home/raul/LLVM/tests//test.c:8: undefined reference
