Hooray!

----------------
first -> last I think, better explained as rightmost. See
SelectionTree::create().

actually, if this is really only used for macros and auto, you could pull out
those specific cases (define AutoLoc and IdentifierLoc and initialize them by
looping over the touching tokens). Seems a bit simpler/more direct/less risk of
reuse for other things?
================
Comment at: clang-tools-extra/clangd/Hover.cpp:540
+ for (const auto &Tok : TokensAroundCursor) {
+ if (Tok.kind() != tok::identifier)
+ continue;
----------------
This deserves a comment, it's a different strategy than SelectionTree that
should yield the same result.
("In general we prefer the touching token that works over the one that doesn't,
see SelectionTree::create(). This location is used only for triggering on
macros and auto, so simply choosing the lone identifier-or-keyword token is
equivalent")

you also need to check for keyword (or specifically kw auto)
