86330afd - SemaCXX: Don't crash when annotation tokens show up before the tag name

Mon, 29 Dec 2014 02:14:26 +0000

SemaCXX: Don't crash when annotation tokens show up before the tag nameClang has a hack to accept definitions of structs with tag names whichhave the same name as intrinsics. However, this hack didn't guardagainst annotation tokens showing up in the token stream.llvm-svn: 224909 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/libstdcxx_is_pod_hack.cpp

8bea83a8 - Extend the "__is_pod" hack, which demotes various type trait keywords

Thu, 30 Aug 2012 20:04:43 +0000

Extend the "__is_pod" hack, which demotes various type trait keywords(__is_pod, __is_signed, etc.) to normal identifiers if they areencountered in certain places in the grammar where we know that priorversions of libstdc++ or libc++ use them, to still allow the use ofthese keywords as type traits.

06873099 - libstdc++ 4.4 uses __is_signed as an identifier, while Clang treats it

Thu, 28 Apr 2011 15:48:45 +0000

libstdc++ 4.4 uses __is_signed as an identifier, while Clang treats itas a keyword for the __is_signed type trait. Cope with this conflictvia some hackish recovery: if we see a declaration of the form static const bool __is_signedthen we stop treating __is_signed as a keyword and instead treat it asan identifier. It's ugly, but it's better than making the __is_signedtype trait conditional on some language flag.

01e09d9d - Introduce an egregious hack to work around a bug in libstdc++ 4.2.x's

Thu, 08 Apr 2010 18:16:15 +0000

Introduce an egregious hack to work around a bug in libstdc++ 4.2.x's header, where a friend class templatestd::tr1::__detail::_Map_base is declared with the wrong templateparameters. GCC doesn't catch the problem, so Clang does a littleback-flip to avoid diagnosing just this one instance of the problem.llvm-svn: 100790 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/libstdcxx_is_pod_hack.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/libstdcxx_is_pod_hack.cpp

119b0c71 - Introduce an egregious hack to fix PR4828.

Fri, 04 Sep 2009 05:53:02 +0000

Introduce an egregious hack to fix PR4828.The problem this change addresses is that we treat __is_pod and__is_empty as keywords in C++, because they are built-in type traitsin GCC >= 4.3. However, GNU libstdc++ 4.2 (and possibly earlierversions) define implementation-detail struct templates named __is_podand __is_empty. This commit solves the problem by recognizing struct __is_podand struct __is_emptyas special token sequences. When one of these token sequences isencountered, the keyword (__is_pod or __is_empty) is implicitlydowngraded to an identifier so that parsing can continue. This is anegregious hack, but it has the virtue of "just working" whethersomeone is using libstdc++ 4.2 or not, without the need for specialflags.llvm-svn: 80988 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/libstdcxx_is_pod_hack.cpp
