From 70c272004f727457e852ba5f2498754b07a7d995 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Fri, 24 Mar 2017 16:07:03 -0400 Subject: gallium/util: libunwind support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It's kinda sad that (a) we don't have debug_backtrace support on !X86 and that (b) we re-invent our own crude backtrace support in the first place. If available, use libunwind instead. The backtrace format is based on what xserver and weston use, since it is nice not to have to figure out a different format.
