aaron.ballman added inline comments.
================
Comment at: include/clang/AST/TypeLoc.h:513
struct BuiltinLocInfo {
- SourceLocation BuiltinLoc;
+ SourceRange BuiltinRange;
};
----------------
Since this doubles the size of the type loc for builtin types, do you happen to
have any data on what practical impact this has on RAM usage, say for
bootstrapping LLVM (or compiling any large source base, really)? Hopefully it's
not a lot, but it would be nice to know if it's a .1%, 1%, 10%, etc increase in
usage (or does the change get lost in the noise).
================
Comment at: unittests/AST/SourceLocationTest.cpp:228
+}
+
TEST(CXXConstructorDecl, NoRetFunTypeLocRange) {
----------------
Can you also add a test that the range is correct for something like `long
double` and `long double _Complex`?
