URL: https://github.com/llvm/llvm-project/commit/9c4a716c1292096fcbdf415b63b7b0122b03310f DIFF: https://github.com/llvm/llvm-project/commit/9c4a716c1292096fcbdf415b63b7b0122b03310f.diff LOG: [clang] Preserve Qualifiers and type sugar in TemplateNames (#93433) This patch improves the preservation of qualifiers and loss of type sugar in TemplateNames. This problem is analogous to https://reviews.llvm.org/D112374 and this patch takes a very similar approach to that patch, except the impact here is much lesser. When a TemplateName was written bare, without qualifications, we wouldn't produce a QualifiedTemplate which could be used to disambiguate it from a Canonical TemplateName. This had effects in the TemplateName printer, which had workarounds to deal with this, and wouldn't print the TemplateName as-written in most situations. There are also some related fixes to help preserve this type sugar along the way into diagnostics, so that this patch can be properly tested. - Fix dropping the template keyword. - Fix type deduction to preserve sugar in TST TemplateNames.
