ilya-biryukov added inline comments.
================
Comment at: clang-tools-extra/clangd/Hover.cpp:188
+// Returns the decl that should be used for querying comments, either from
index
+// or ast.
+const NamedDecl *getDeclForComment(const NamedDecl *D) {
----------------
NIT: AST
================
Comment at: clang-tools-extra/clangd/Hover.cpp:205
const SymbolIndex *Index) {
- if (!Index || !llvm::isa<NamedDecl>(D))
- return;
- const NamedDecl &ND = *cast<NamedDecl>(D);
// We only add documentation, so don't bother if we already have some.
+ if (!Hover.Documentation.empty() || !Index)
----------------
NIT: maybe add `assert(&ND == getDeclForComment(&ND))`?
================
Comment at: clang-tools-extra/clangd/Hover.cpp:377
- if (HI.Name.empty()) {
+ const auto *ND = getDeclForComment(D);
+ HI.Documentation = getDeclComment(ASTCtx, *ND);
----------------
NIT: `ND` suggests it's the same as `D` with a different type.
I'd use a different name, even if it's larger, e.g. `CommentD`
================
Comment at: clang-tools-extra/clangd/Hover.cpp:418
+const Decl *preferInstantiation(llvm::iterator_range<const Decl **> Range) {
+ if (Range.empty())
+ return nullptr;
----------------
This seems to be doing exactly the same thing as `explicitReferenceTargets`
from `FindTarget.cpp`
WDYT about exposing the latter in `FindTarget.h` and using it here?
It seems to be pretty well-defined and useful.
