2013-04-16Don't put too much thought into whether or not to capture aJohn McCall
type-dependent intermediate result in a postfix ++ pseudo- object operation. Test case by Tong Shen. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179637 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-16Basic support for Microsoft property declarations andJohn McCall
references thereto. Patch by Tong Shen! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179585 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-12Accept over-qualified constructor in MSVC emulation modeDmitri Gribenko
MSVC accepts this: class A { A::A(); }; Clang accepts regular member functions with extra qualification as an MS extension, but not constructors. This changes the parser to defer rejecting qualified constructors so that the same Sema logic can apply to constructors as regular member functions. This also improves the error message when MS extensions are disabled (in my opinion). Before it was: /Users/jason/Desktop/test.cpp:2:8: error: expected member name or ';' after declaration specifiers A::A(); ~~~~ ^ 1 error generated. After: /Users/jason/Desktop/test.cpp:2:6: error: extra qualification on member 'A' A::A(); ~~~^ 1 error generated. Patch by Jason Haslam. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174980 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-02Change diagnostics for enums with fixed underlying type so in C++98 mode, we ↵Eli Friedman

2012-09-13Promote the warning about extra qualification on a declaration from aDouglas Gregor
warning to an error. C++ bans it, and both GCC and EDG diagnose it as an error. Microsoft allows it, so we still warn in Microsoft mode. Fixes <rdar://problem/11135644>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163831 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-16Shift Microsoft enum extensions from -fms-extensions to -fms-compatibility, ↵Eli Friedman
so -fms-extensions doesn't affect enum semantics in incompatible ways. <rdar://problem/10657186>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150663 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-21In Microsoft Mode, disable the C++11 strict integral conversion rules for ↵Francois Pichet
enumerator that were introduced with r148439. Otherwise MSVC headers won't compile in C++ 11 mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148642 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-21Treat the Microsoft/Borland keyword "__except" as a context-sensitiveDouglas Gregor
keyword, because both libstdc++ and libc++ use "__except" as an identifier. Fixes <rdar://problem/10322555>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142636 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-17When we end up having to parse the initializer of a C++ member earlyDouglas Gregor
in -fms-extensions mode, make sure we actually use that initializer after having handled the declaration. Fixes PR11150. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142195 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-21[microsoft] Move missing typename warning from -fms-extensions to ↵Francois Pichet
-fms-compatibility. Also allow the missing typename warning at function scope. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140240 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-20Move Microsoft access specifier bug emulation from -fms-extensions to ↵Francois Pichet
-fm-compatibility. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140189 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-18Move the "jump bypasses variable initialization" error -> warning downgrade ↵Francois Pichet
from -fms-extensions to -fms-compatibility. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140008 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-16In Microsoft mode, warn if an indirect goto jump over a variable initialization.Francois Pichet
Also add a test case for the non Microsoft case because such test didn't exist. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139971 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13In Microsoft mode, downgrade "goto into protected scope" from error to ↵Francois Pichet
warning if we are jumping over a variable initialization via a goto. This fixes a few errors when parsing MFC code with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139595 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-18Add support for MSVC __unaligned attribute. Necessary to parse MSVC headers ↵Francois Pichet

2011-06-01Microsoft friend acting as a forward declaration; try#2. Now only 2 lines.Francois Pichet
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@132387 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-31Revert 132332 (Microsoft friend as a forward declaration), John McCall ↵Francois Pichet
pointed out a better/simpler way to do it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@132369 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-31For compatibility with MSVC, a friend declaration also act as a forward ↵Francois Pichet
declaration if the tag name is not already declared. The tag name is declared in the next outermost non record scope. Example: class A { friend class B; B* b; }; B* global_b; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@132332 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-24MSVC doesn't do any validation regarding exception specification.Francois Pichet
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131950 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-23Emulate a MSVC bug where if during an using declaration name lookup, the ↵Francois Pichet
declaration found is unaccessible (private) and that declaration was bring into scope via another using declaration whose target declaration is accessible (public) then no error is generated. Example: class A { public: int f(); }; class B : public A { private: using A::f; }; class C : public B { private: using B::f; }; Here, B::f is private so this should fail in Standard C++, but because B::f refers to A::f which is public MSVC accepts it. This fixes 1 error when parsing MFC code with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131896 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-14Revert 131347. It asserts if the specialization in within a class template:Francois Pichet
template<class U> struct X1 { template<class T> void f(T*); template<> void f(int*) { } }; Won't be so simple. I need to think more about it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131362 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-14In Microsoft mode, allow template function explicit specialization at class ↵Francois Pichet
scope. Necessary to parse MFC and MSVC standard lib code. Example: struct X { template<class T> void f(T) { } template<> void f(int) { } } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131347 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-11In Microsoft mode, allow conversion from pointer to integral type no matter ↵Francois Pichet
what size the integral type is. Necessary to parse MFC code. Example: void f(char *ptr) { char var = (char)ptr; } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131201 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-08Allow implicit conversion from function pointer to void* in Microsoft mode. Francois Pichet
Necessary to parse MFC code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131076 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-22Downgrade error "static declaration of 'foo' follows non-static declaration" ↵Francois Pichet
to a warning in Microsoft mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129985 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-13In Microsoft mode, within class scope, if a CXXScopeSpec's type is equal to ↵Francois Pichet
the type of one of the base classes then downgrade the missing typename error to a warning. Up to now this is the only case I found where MSVC doesn't require "typename" at class scope. Really strange! This fixes 1 error when parsing the MSVC 2008 header files. Example: template<class T> class A { public: typedef int TYPE; }; template<class T> class B : public A<T> { public: A<T>::TYPE a; // no typename required because A<T> is a base class. }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129425 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-10MSVC accepts that default parameters be redefined for member functionsFrancois Pichet
of template class. The new value is ignored. This fixes 1 error when parsing MSVC 2010 header files with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129240 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128459 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-29Accept __declspec(dllimport) for function defined at class scope in ↵Francois Pichet
Microsoft mode. This fixes a bunch of errors when compiling MSVC header files with the -DDLL flag. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128457 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-19Downgrade err_mismatched_exception_spec to a ExtWarning in Microsoft mode. ↵Francois Pichet
MSVC doesn't do any validation on exception specifications. This remove 1 error when parsing MSVC stl lib with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127961 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-02Semantic checking for exception specifications should be triggered byJohn McCall
whether C++ exceptions are enabled, not exceptions in general. PR9358. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126820 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-22Enable enumeration types with a fixed underlying type, e.g.,Douglas Gregor
enum X : long { Value = 0x100000000 }; when in Microsoft-extension mode (-fms-extensions). This (now C++0x) feature has been supported since Microsoft Visual Studio .NET 2003. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126243 91177308-0d34-0410-b5e6-96231b3b80d8
