Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2025-01-03 13:26:34 UTC 
We could optionally run `gdb-add-index` on ELF when we're not stripping binaries to make gdb startup/parsing faster.

wrt bug 938763: If we adopt find-debuginfo, we can do this with find-debuginfo -i.
Comment 1 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2025-01-03 13:29:10 UTC 
https://fedoraproject.org/wiki/Changes/DebugInfoLldbIndex#Detailed_Description is a summary of the different index types, but we should check how up-to-date the information there is.
Comment 2 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2025-01-03 13:31:59 UTC 
We'd probably want `gdb-add-index -dwarf-5`.
Comment 3 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2025-01-03 20:07:53 UTC 
Given https://sourceware.org/bugzilla/show_bug.cgi?id=31363, we certainly do want -dwarf-5 to get .debug_names instead.
