David Lamparter	4894e9c12a	lib: stuff xrefs into a tree for lookup ... ... so we can actually access by UID without searching the entire list. Signed-off-by: David Lamparter <equinox@diac24.net>	2021-11-10 10:39:17 +01:00

David Lamparter	08a73c422d	lib/xref: work around GCC bug 41091 ... gcc fucks up global variables with section attributes when they're used in templated C++ code. The template instantiation "magic" kinda breaks down (it's implemented through COMDAT in the linker, which clashes with the section attribute.) The workaround provides full runtime functionality, but the xref extraction tool (xrelfo.py) won't work on C++ code compiled by GCC. FWIW, clang gets this right.

David Lamparter	8e427c2938	lib: "xref" identifier infrastructure ... This adds the machinery for cross reference points (hence "xref") for things to be annotated with source code location or other metadata and/or to be uniquely identified and found at runtime or by dissecting executable files. The extraction tool to walk down an ELF file is done and working but needs some more cleanup and will be added in a separate commit.
