If he doesn't have time, I am reasonably confident with the patch to merge it. If we think he won't have time, I think it's better to merge it earlier than later, that gives more time for any potential problem to surface. > * [] > [GNU/Linux, sparc64] GDB is unable to print full stack trace (got "previous frame inner to this frame" errors) > https://sourceware.org/bugzilla/show_bug.cgi?id=27147 > > As the subject says, it's an unwinder issue. > Simon was able to reproduce, and tied this issue to a specific > commit adding multi-target support. > > It's a 9->10 regression, so it would be nice to fix, but the risk > at the moment, is that the PR is currently not assigned, so there is > no "champion" to look after it. > > Simon also requested we consider: > > * [SimonM] > DW_FORM_rnglistx and DW_FORM_loclistx not fully supported > https://sourceware.org/bugzilla/show_bug.cgi?id=26813 > > Simon posted a patch series on Jan 20th: > [PATCH 00/13] DWARF 5 rnglists & loclists fixes (PR 26813) > https://sourceware.org/pipermail/gdb-patches/2021-January/175221.html This is now pushed on master. Do I have your OK to backport it? My argument for backporting it is that support for processing these DWARF5 attributes was new in GDB 10, but GDB chokes on any non-trivial use of them (like when there are two compile units using rnglists). Not all patches are tagged with PR 26813 (because they are cleanups/refactor), but the important ones, that contain the actual fixes, do have it. Is that ok for the release branch? Simon
