[LLVMdev] Recent changes in -gmlt break sample profiling
I'm not sure if this was intended, but it's going to be a problem for sample profiles. When we compile with -gmlt, the profiler expects to find the line number for all the function headers so that it can compute relative line locations for the profile. The tool that reads the ELF binary is not finding them, so it writes out absolute line numbers, which are impossible to match during the
