<p>Please don't. Every time I have seen that flag used the intention was to omit the eh_frame section completely.

<p>I think the two reasonable solutions are to always emit precise info (modulo bugs) or to have a *new* command line to enable imprecise mode.<o:p></o:p></p>

<p class="MsoNormal" style="line-height:115%">I agree, I've looked into the meaning of -fasynchronous-unwind-tables, and for GCC that just controls the emission of .eh_frame. Their CFI is always precise at every instruction, bugs aside. I think we should do
the same.<o:p></o:p></p>
