[PATCH 7/9] perf/jit: generate .eh_frame/.eh_frame_hdr in DSO

2016-10-13 Thread Stephane Eranian
From: Stefano Sanfilippo When the jit_buf_desc contains unwinding information, it is emitted as eh_frame unwinding sections in the DSOs generated by perf inject. The unwinding information is required to unwind of JITed code which do not maintain the frame pointer
