...ence because we always shrink in the first round and always grow in the second. Data shows that our relaxation is efficient. For example, for clang, the aggressive shrinking affects ~995000 branches in 6 iterations and only 4 branches had to be grown back.

Hi, I have this call instruction to printf inserted which is causing an assertion failure. Any pointers to where I am wrong : Code Dump : Function *printFn=M.getNamedFunction(std::string("printf")); Constant *str=ConstantArray::get("Value : %d\n"); std::vector<Value *> Args(2); std::vector<Constant *> GEPIndices(2);

Hi, i ran the insert-function-profiling pass on my bytecode and when i jit it, i get ' cant resolve 'llvm_start_func_profiling'. How do I link the "instrument" library. ? Thanks -Sriraman.

You can also see the resulting module by using -disable-verify: $ opt -yourpass -disable-verify < file.bc | llvm-dis You may see what the problem is by looking at the LLVM assembly....

Hi, I want to get all the d-u pairs exercised at run-time. I am doing two things for this. I am useing the d-u iterator to instrument all uses. I also want to get an address trace. What are the instructions I should insttrument. Is load and store sufficient. Also, how do I go abt doing this ? Thanks -Sriraman.

...they do not increase at all. Krys talked about this earlier. 2) We do deduplication of common static CFI instructions in the FDE and move it to the CIE . Hence, moving to a new basic block does not mean a completely new set of CFI instructions is executed.

...chmarks we would appreciate it if you could share it. Further, if you have a recipe to use jemalloc with BOLT, please point it at us. We could try it out too and share our findings.
