I’d like to get it working when requested by –fomit-frame-pointer first, then consider whether some target triples cause it to be enable it by default when optimizing. I’m aware of issues around debugger support and unwinding, but was wondering if anyone else had any thoughts/guidance that might be helpful. Specifically, I’d like to hear from any of the implementers of the current AArch64 frame lowering if they know of any pitfalls to be aware of.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal>-Geoff<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:dashed #2F6FAB 1.0pt;padding:12.0pt 12.0pt 12.0pt 12.0pt;background:#F9F9F9'><p class=MsoNormal style='line-height:15.6pt;background:#F9F9F9;border:none;padding:0in'>--<o:p></o:p></p><p class=MsoNormal style='line-height:15.6pt;background:#F9F9F9;border:none;padding:0in'>Geoff Berry<o:p></o:p></p><p class=MsoNormal style='line-height:15.6pt;background:#F9F9F9;border:none;padding:0in'>Employee of Qualcomm Innovation Center, Inc.<o:p></o:p></p><p class=MsoNormal style='line-height:15.6pt;background:#F9F9F9;border:none;padding:0in'> Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project<o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p></div></body></html>
