<div dir="ltr">DW_AT_frame_base is largely used as a beginning offset to find things for other expressions, for example it can be used to short cut location information for variables (+/- from the frame base which could be a complicated expression) or used to find captured variables that might be on another function's stack (largely nested functions). It can also help with giving a shortcut for inlined function stack frames if they're distinct, but afaik we don't do that :)<div><br></div><div>So unless we're going to start giving out variable contents with gmlt we don't need to worry.<div><br></div><div>-eric<br><div><br></div><div><br></div></div></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Wed, Aug 27, 2014 at 4:55 PM, Chandler Carruth <span dir="ltr"><<a href="mailto:chandlerc@google.com" target="_blank">chandlerc@google.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><br><div class="gmail_quote"><span class="">On Wed, Aug 27, 2014 at 4:40 PM, David Blaikie <span dir="ltr"><<a href="mailto:dblaikie@gmail.com" target="_blank">dblaikie@gmail.com</a>></span> wrote:<br>
