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 to `llvm_start_edge_profiling' collect2: ld returned 1 exit status Does anybody know which is the problem? I'm using LLVM 2.1 and LLVM-GCC 4.2 (both were built from SVN source code). Thanks...

...n executable in the native program. I was trying an instrumentation transform with the following workflow opt -insert-edge-profiling input.bc -o output.bc and then try and execute output.bc using lli output.bc however the program gives the following error : Program used external function 'llvm_start_edge_profiling' which could not be resolved!. Could anyone guide me to the correct workflow for doing such transforms and then executing them? Thanks Nipun -------------- next part -------------- An HTML attachment was scrubbed...

I'm an LLVM newbie, trying to write a pass that adds instrumentation to a program, and have a couple of questions. For purposes of this discussion, suppose I'm trying to add a per-function counter that is incremented each time a function is called. At the end of the target program's execution, I would like to output the value of each counter. My questions are as follows: 1.

Hi, I am trying to test my project and get the code coverage with a version of clang compiler that was built from the latest llvm/clang codebase. It worked for a while. But today, after I updated my local checkout, and re-build llvm, clang and compiler-rt, when I test my project again, I got the errors with undefined reference to 'llvm_gcda_start_file', 'llvm_gcda_emit_arcs',

hi, I'm newer in llvm i would like to instrument a byte code with a pass and as a result i would like to get an instrumented byte code. i would like that a pass add a method (which calculate the number of instructions) in the end of each block. the instrumented code should contain in each block a method that calculate the number of instructions Please Help me thank you -- Nabila ABDESSAIED
