> Attached patch adds 64bit eh_frame section support.<br>
><br>
> In practice, 64bit eh_frame is not used even for x86_64 binaries. The main reason is in eh_frame we almost always use pc-relative addressing, so addresses are within 32bits and gcc just sticks to 32bit eh_frame.<br>

> I generated 64bit eh_frame for Android Java runtime and unwind successfully in gdb, and in lldb with this patch.<br>
