Aha, I think I may have found an invalid ordering expectations in Clang's test
then. Here is the key difference between my fork and upstream in
DiagnosticGroups.inc:
--8<---------------cut here---------------start------------->8---
#ifdef GET_CATEGORY_TABLE
CATEGORY("", DiagCat_None)
CATEGORY("Lexical or Preprocessor Issue", DiagCat_Lexical_or_Preprocessor_Issue)
-CATEGORY("Parse Issue", DiagCat_Parse_Issue)
CATEGORY("Semantic Issue", DiagCat_Semantic_Issue)
+CATEGORY("Parse Issue", DiagCat_Parse_Issue)
CATEGORY("Automatic Reference Counting Issue", DiagCat_Automatic_Reference_Counting_Issue)
CATEGORY("Inline Assembly Issue", DiagCat_Inline_Assembly_Issue)
CATEGORY("Modules Issue", DiagCat_Modules_Issue)
--8<---------------cut here---------------end--------------->8---
The category indices for Parse Issue and Semantic Issue have been flipped.
Any idea what could cause this to happen? I haven't renamed, added or deleted
any files in include/clang/Basic...
Thanks,
