+ if (clang::Lexer::getRawToken(Loc, Tok, SM, LO))
+ return false;
----------------
You've changed this from tokenizing the file with a cache.
If I'm reading your benchmark spreadsheet right, this is ~3% speedup.
I'm not sure this is significant (I imagine not), but you don't actually have
to run the lexer here, since you already know what the string is going to be,
it's enough to grab the buffer pointer, check that it starts with the text,
check that the next character is not an identifier-continuer.

Comment at: clang-tools-extra/clangd/index/SymbolCollector.cpp:710
// FIXME: Populate container information for macro references.
- MacroRefs[ID].push_back({Loc, Roles, /*Container=*/nullptr});
+ // FIXME: All macro references are marked as Spelled now, but this should
be
+ // checked.

oops nevermind, you're only moving this comment from elsewhere
