Backtracing through eh_frame section is more effective allowing to reuse ebp register for other purposes within routine. GCC with turned on optimizations (-O1 and above) implicitly defines -fomit-frame-pointer anyway. eh_frame sections are generated by default with GCC on any optimization level. This change implements remote unwinding (separate process unwinding). Local unwinding is already implemented through _Unwind_Backtrace call which is implemented in libgcc.
