a4ca4ca2 - Fix -Wmismatched-tags to not warn on redeclarations of structs in system

Tue, 04 Dec 2018 02:45:28 +0000

Fix -Wmismatched-tags to not warn on redeclarations of structs in systemheaders.Previously, we would only check whether the new declaration is in asystem header, but that requires the user to be able to correctly guesswhether a declaration in a system header is declared as a struct or aclass when specializing standard library traits templates.We now entirely ignore declarations for which the warning was disabledwhen determining whether to warn on a tag mismatch.Also extend the diagnostic message to clarify that a) code containing such a tag mismatch is in fact valid and correct, and b) the (non-coding-style) reason to emit such a warning is that the Microsoft C++ ABI is broken and includes the tag kind in decorated names,as it seems a lot of users are confused by our diagnostic here (eithernot understanding why we produce it, or believing that it represents anactual language rule).llvm-svn: 348233 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/struct-class-redecl.cpp

738e5879 - Sema: Don't crash when an inject class name has a nested redefinition

Sun, 28 Dec 2014 09:18:54 +0000

Sema: Don't crash when an inject class name has a nested redefinitionWe expected the type of a TagDecl to be a TagType, not anInjectedClassNameType. Introduced a helper method, Type::getAsTagDecl,to abstract away the difference; redefine Type::getAsCXXRecordDecl to bein terms of it.llvm-svn: 224898 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/struct-class-redecl.cpp

925213b0 - Add 'not' to commands that are expected to fail.

Add 'not' to commands that are expected to fail.This is at least good documentation, but also opens the possibility ofusing pipefail.llvm-svn: 185652 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/struct-class-redecl.cpp

caa33d36 - Made changes to how 'struct'/'class' mismatches are handled in -Wmismatched-tags.

Fri, 10 Jun 2011 03:11:26 +0000

Made changes to how 'struct'/'class' mismatches are handled in -Wmismatched-tags.- Removed fix-it hints from template instaniations since changes to thetemplates are rarely helpful.- Changed the caret in template instaniations from the class/struct name to theclass/struct keyword, matching the other warnings.- Do not offer fix-it hints when multiple declarations disagree. Warnings arestill given.- Once a definition is found, offer a fix-it hint to all previous declarationswith wrong tag.- Declarations that disagree with a previous definition will get a fix-it hintto change the declaration.llvm-svn: 132831 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/struct-class-redecl.cpp

8fbe78f6 - Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.

Tue, 15 Dec 2009 20:14:24 +0000

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target).llvm-svn: 91446 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/struct-class-redecl.cpp

d9034f0b - In C++, warn when something previously declared as a "struct" is later

In C++, warn when something previously declared as a "struct" is laterdeclared as a "class", or vice-versa. This warning is under thecontrol of -Wmismatched-tags, which is off by default.llvm-svn: 71773 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/struct-class-redecl.cpp
