2012-06-19Reapply r158700 and fixup patches, minus one hunk that slipped through andSean Hunt
caused a crash in an obscure case. On the plus side, it caused me to catch another bug by inspection. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158767 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Extend the support for cl-std to include 1.2.Tanya Lattner
Add error checking for the static qualifier which is now allowed in certain situations for OpenCL 1.2. Use the CL version to turn on this feature. Added test case for 1.2 static storage class feature. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158759 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Revert r158700 and dependent patches r158716, r158717, and r158731.Jakob Stoklund Olesen
The original r158700 caused crashes in the gcc test suite, g++.abi/vtable3a.C among others. It also caused failures in the libc++ test suite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158749 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Improve the specification of spellings in Attr.td.Sean Hunt
Note that this is mostly a structural patch that handles the change from the old spelling style to the new one. One consequence of this is that all AT_foo_bar enum values have changed to not be based off of the first spelling, but rather off of the class name, so they are now AT_FooBar and the like (a straw poll on IRC showed support for this). Apologies for code churn. Most attributes have GNU spellings as a temporary solution until everything else is sorted out (such as a Keyword spelling, which I intend to add if someone else doesn't beat me to it). This is definitely a WIP. I've also killed BaseCheckAttr since it was unused, and I had to go through every attribute anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158700 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-02Revert most of r154844, which was disabled in r155975. Keep around theRichard Smith
refactorings in that revision, and some of the subsequent bugfixes, which seem to be relevant even without delayed exception specification parsing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156031 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-16Implement the last part of C++ [class.mem]p2, delaying the parsing ofDouglas Gregor
exception specifications on member functions until after the closing '}' for the containing class. This allows, for example, a member function to throw an instance of its own class. Fixes PR12564 and a fairly embarassing oversight in our C++98/03 support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154844 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-04For PR11916: Add support for g++'s __int128 keyword. Unlike __int128_t, this isRichard Smith
a type specifier and can be combined with unsigned. This allows libstdc++4.7 to be used with clang in c++98 mode. Several other changes are still required for libstdc++4.7 to work with clang in c++11 mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153999 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-25Fix a couple more issues related to r133854:Richard Smith
When performing semantic analysis on a member declaration, fix the check for whether we are declaring a function to check for parenthesized declarators, declaration via decltype, etc. Also fix the semantic check to not treat FuncType* as a function type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@133862 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-25When deciding how to parse "= something" as part of a memberDouglas Gregor
declaration, determine whether the declaration will end up declaring a function using semantic criteria (e.g., it will have function type) rather than purely syntactic criteria (e.g., it has the form of a function declarator).

2011-03-03Fix PR9390 in not one, but two ways:Douglas Gregor
1) When we do an instantiation of the injected-class-name type, provide a proper source location. This is just plain good hygiene. 2) When we're building a NestedNameSpecifierLoc from a CXXScopeSpec, only return an empty NestedNameSpecifierLoc if there's no representation. Both problems contributed to the horrible test case in PR9390 that I couldn't reduce down to something palatable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126961 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-24Teach NestedNameSpecifier to keep track of namespace aliases the sameDouglas Gregor
way it keeps track of namespaces. Previously, we would map from the namespace alias to its underlying namespace when building a nested-name-specifier, losing source information in the process. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126358 91177308-0d34-0410-b5e6-96231b3b80d8
