2010-07-14Only filter out names reserved for the implementation (e.g., __blah orDouglas Gregor
_Foo) from code-completion results when they come from a system header. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108338 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-14Fix the mangling of template template arguments, which do not alwaysJohn McCall
follow <name>; instead they follow <type>, which has <name> as a subset. Fixes PR7446. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108326 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-14Wire up '-Wignored-qualifiers' to the warning on 'const' in 'const int f()'.Chandler Carruth
This flag and warning match GCC semantics. Also, move it to -Wextra as this is a largely cosmetic issue and doesn't seem to mask problems. Subsequent fixes to the tests which no longer by default emit the warning. Added explicit test cases for both C and C++ behavior with the warning turned on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108325 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-14Remove a few mangling FIXMEs:John McCall
- TSTs whose template is a template template parameter already work - we don't provide an imaginary type, so we can't mangle one - we don't need a generic FIXME for vendor type qualifiers git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108317 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-13Work around an obnoxious GCC warning by changing semantics in a hopefully-John McCall
harmless way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108295 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13Introduce a new cast kind for an "lvalue bitcast", which handlesDouglas Gregor
reinterpret_casts (possibly indirectly via C-style/functional casts) on values, e.g., int i; reinterpret_cast<short&>(i); The IR generated for this is essentially the same as for *reinterpret_cast<short*>(&i). Fixes PR6437, PR7593, and PR7344. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108294 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-13Set DeclContext of ParamVarDecl only. No needFariborz Jahanian
to set that of VarDecl for block variables (they are already set). Per Doug's comment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108273 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13Teach IR generation how to lazily emit cleanups. This has a lot of advantages,John McCall
mostly in avoiding unnecessary work at compile time but also in producing more sensible block orderings. Move the destructor cleanups for local variables over to use lazy cleanups. Eventually all cleanups will do this; for now we have some awkward code duplication. Tell IR generation just to never produce landing pads in -fno-exceptions. This is a much more comprehensive solution to a problem which previously was half-solved by checks in most cleanup-generation spots. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108270 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-13Whenever we're creating an expression that is typically an rvalueDouglas Gregor
(e.g., a call, cast, etc.), immediately adjust the expression's type to strip cv-qualifiers off of all non-class types (in C++) or all types (in C). This effectively extends my previous fix for PR7463, which was restricted to calls, to other kinds of expressions within similar characteristics. I've audited every use of getNonReferenceType() in the code base, switching to the newly-renamed getNonLValueExprType() where necessary. Big thanks to Eli for pointing out just how incomplete my original fix for PR7463 actually was. We've been handling cv-qualifiers on rvalues wrong for a very, very long time. Fixes PR7463. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108253 91177308-0d34-0410-b5e6-96231b3b80d8

size" error for code like new (int [size]) to a warning, add a Fix-It to remove the parentheses, and make this diagnostic work properly when it occurs in a template instantiation. <rdar://problem/8018245>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108242 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13Modify the pragma handlers to accept and use StringRefs instead of ↵Argyrios Kyrtzidis
IdentifierInfos. When loading the PCH, IdentifierInfos that are associated with pragmas cause declarations that use these identifiers to be deserialized (e.g. the "clang" pragma causes the "clang" namespace to be loaded). We can avoid this if we just use StringRefs for the pragmas. As a bonus, since we don't have to create and pass IdentifierInfos, the pragma interfaces get a bit more simplified. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108237 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-13When computing the canonical profile of a DeclRefExpr or MemberExpr,Douglas Gregor
don't include the nested-name-specifier or template arguments: they were only relevant when resolving the declaration. Fixes PR7460. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108235 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13When forming a function call or message send expression, be sure toDouglas Gregor
strip cv-qualifiers from the expression's type when the language calls for it: in C, that's all the time, while C++ only does it for non-class types. Centralized the computation of the call expression type in QualType::getCallResultType() and some helper functions in other nodes (FunctionDecl, ObjCMethodDecl, FunctionType), and updated all relevant callers of getResultType() to getCallResultType(). Fixes PR7598 and PR7463, along with a bunch of getResultType() call sites that weren't stripping references off the result type (nothing stripped cv-qualifiers properly before this change). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108234 91177308-0d34-0410-b5e6-96231b3b80d8
