From 476ea45c68223e4b2f9674d20f1aff8dd52fe1fb Mon Sep 17 00:00:00 2001 From: Hood Chatham Date: Wed, 16 Oct 2024 12:22:14 +0200 Subject: [PATCH] Emscripten: Xfail backtrace ui tests It is possible to link libunwind and use the normal backtrace code, but it fails to symbolize stack traces. I investigated and could get the list of instruction pointers and symbol names, but I'm not sure how to use the dwarf info to map from instruction pointer to source location. In any case, fixing this is probably not a high priority.
