llvm-propeller test program (main.cc, callee.cc) fails after the optimizations. about llvm-propeller HOT 7 CLOSED

@rlavaee Can you help? TIA.

Thanks for filing the issue. Please make sure the output name is the same between perf.propeller file and the final binary name. Otherwise, the ordering will not take effect (as reported by create_llvm_prof). The segfault happens because of an out_of_bounds access in main.cc (argv[1]).
For sanity check, you may want to reproduce results from plo/sample.c (cd plo ; make sample.propeller.out)

@rlavaee Thanks for pointing out missing argument error (OOPS!). BTW, there seems to be few dependencies to build "sample.propeller.out" such as BOLT and perf2bolt. Do I need to build these tools?

$ make sample.propeller.out
Failed ....

$ make stage1-compiler # Worked

$ make sample.propeller.out
...
./stage1-compiler -fuse-ld=lld -Wl,-O2 -o sample.out sample_bblabels.o

make: *** No rule to make target '/mnt/sdb1/upawar/create_llvm_prof_dir/*.cc', needed by '/mnt/sdb1/upawar/create_llvm_prof_dir/create_llvm_prof'. Stop.

Note: I updated paths.mk for "create_llvm_prof_dir" directory.
Please let me know if any other build environment is missing.

Any help is appreciated. TIA.

@rlavaee Can you help with this issue please? Am I missing anything? TIA.

@uttampawar Please resync. I've pushed a fix to break the BOLT dependencies.

@rlavaee I'll update the issue with my findings. Thanks.

This fixes the build issue.
