2009-04-12mark the declspec as invalid when we recover instead of forcing to int,Chris Lattner
this allows downstream diags to be properly silenced. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68917 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-12Diagnose invalid uses of tagged types with a missing tag. For example, in:Chris Lattner
struct xyz { int y; }; enum abc { ZZZ }; static xyz b; abc c; we used to produce: t2.c:4:8: error: unknown type name 'xyz' static xyz b; ^ t2.c:5:1: error: unknown type name 'abc' abc c; ^ we now produce: t2.c:4:8: error: use of tagged type 'xyz' without 'struct' tag static xyz b; ^ struct t2.c:5:1: error: use of tagged type 'abc' without 'enum' tag abc c; ^ enum GCC produces the normal: t2.c:4: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘b’ t2.c:5: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘c’ rdar://6783347 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68914 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-12fix a valgrind problem I noticed while developing another patch,Chris Lattner
if a decl is invalid, it isn't added to the Decls array, so we need to pass in Decls.size() to avoid reading uninit memory. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68913 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-12Implement the first set of changes for PR3963 and rdar://6759604,Chris Lattner
which tries to do better error recovery when it is "obvious" that an identifier is a mis-typed typename. In this case, we try to parse it as a typename instead of as the identifier in a declarator, which gives us several options for better error recovery and immediately makes diagnostics more useful. For example, we now produce: t.c:4:8: error: unknown type name 'foo_t' static foo_t a = 4; ^ instead of: t.c:4:14: error: invalid token after top level declarator static foo_t a = 4; ^ Also, since we now parse "a" correctly, we make a decl for it, preventing later uses of 'a' from emitting things like: t.c:12:20: error: use of undeclared identifier 'a' int bar() { return a + b; } ^ I'd really appreciate any scrutiny possible on this, it is a tricky area. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68911 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-12a few cleanups to StatementCreatesScope: unnest the whole thing,Chris Lattner
exit at the first decl found that creates a scope, don't evaluate decl_end() every iteration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68908 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-12Add deleted functions and rvalue references to C++ status.Sebastian Redl
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68903 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-12Parse deleted member functions. Parsing member declarations goes through a ↵Sebastian Redl
different code path that I forgot previously. Implement the rvalue reference overload dance for returning local objects. Returning a local object first tries to find a move constructor now. The error message when no move constructor is defined (or is not applicable) and the copy constructor is deleted is quite ugly, though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68902 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-12Fix rdar://6771034: don't warn on use of forward declared protocol in protocolChris Lattner
list of another protocol definition. This warning is very noisy and GCC doesn't produce it so existing code doesn't expect it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68894 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-12call objc interfaces just "interfaces" in diagnostics, not "Objective-C types"Chris Lattner
or "Objective-C interface types" etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68892 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-11now that we have an identifier table in the PCH file, finish hooking upChris Lattner
macro deserialization. We now correctly install II's in tokens, handle function-like macros, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68882 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-11improve location info for property stuff. In a property like this:Chris Lattner
@property int x; associate the location of X with the property decl, not the location of the @. Also, pass this info along to the synthesized ParmVarDecls so that redefinition and other diagnostics can use it. This eliminates a fixme. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68880 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-11improve the 'conflicting types' diagnostics to include correct location ↵Chris Lattner
info, now that it is plumbed through Sema. On a file from growl, we used to emit: t.mi:107059:1: warning: conflicting types for 'removePluginHandler:forPluginTypes:' - (void) removePluginHandler:(id <GrowlPluginHandler>)handler forPluginTypes:(NSSet *)extensions { ^ t.mi:105280:1: note: previous definition is here - (void) removePluginHandler:(id <NSObject>)handler forPluginTypes:(NSSet *)types; ^ now we produce: t.mi:107059:55: warning: conflicting parameter types in implementation of 'removePluginHandler:forPluginTypes:': 'id<NSObject>' vs 'id<GrowlPluginHandler>' - (void) removePluginHandler:(id <GrowlPluginHandler>)handler forPluginTypes:(NSSet *)extensions { ^ t.mi:105280:45: note: previous definition is here - (void) removePluginHandler:(id <NSObject>)handler forPluginTypes:(NSSet *)types; ^ We still don't have proper loc info for properties, hence the FIXME. rdar://6782494 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68879 91177308-0d34-0410-b5e6-96231b3b80d8

a block without a prototype should still coerce a return in it to use the declared return type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68875 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-11Improve the 'cannot pass objc interface by value' diagnostic:Chris Lattner
1) improve localizability by not passing english strings in. 2) improve location for arguments. 3) print the objc type being passed. Before: method-bad-param.m:15:1: error: Objective-C type cannot be passed by value -(void) my_method:(foo) my_param ^ after: method-bad-param.m:15:25: error: Objective-C interface type 'foo' cannot be passed by value -(void) my_method:(foo) my_param ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68872 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-11Minor refactoring of my last patch.Fariborz Jahanian
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68870 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-11sink abstract typedefs like Action::ExprTy from the Action classChris Lattner
down to the ActionBase class. This eliminates dependencies of (e.g.) DeclSpec.h on Action.h, meaning that action.h can now include these headers and use their types directly in the actions interfaces. This is a refactoring to support a future change, no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68869 91177308-0d34-0410-b5e6-96231b3b80d8
