Initial skeleton of an AST "importer", which will take AST elements from one context and import them into another context, merging them according to language-specific rules. This is a skeleton. It doesn't work, it isn't testable, but I want it in version control. llvm-svn: 95395

Implement basic support for importing source locations from one AST into another AST, including their include history. Here's an example error that involves a conflict merging a variable with different types in two translation units (diagnosed in the third AST context into which everything is merged). /Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var2.c:3:5: error: external variable 'x2' declared with incompatible types in different translation units ('int' vs. 'double') int x2; ^ In file included from /Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var1.c:3: /Volumes/Data/dgregor/Projects/llvm/tools/clang/test/ASTMerge/Inputs/var1.h:1:8: note: declared here with type 'double' double x2; ^ Although we maintain include history, we do not maintain macro instantiation history across a merge.

When AST merging for record declarations fails, warn about the incompatibility and show where the structural differences are. For example: struct1.c:36:8: warning: type 'struct S7' has incompatible definitions in different translation units struct S7 { int i : 8; unsigned j : 8; } x7; ^ struct1.c:36:33: note: bit-field 'j' with type 'unsigned int' and length 8 here struct S7 { int i : 8; unsigned j : 8; } x7; ^ struct2.c:33:33: note: bit-field 'j' with type 'unsigned int' and length 16 here struct S7 { int i : 8; unsigned j : 16; } x7; ^ There are a few changes to make this work: - ASTImporter now has only a single Diagnostic object, not multiple diagnostic objects. Otherwise, having a warning/error printed via one Diagnostic and its note printed on the other Diagnostic could cause the note to be suppressed. - Implemented import functionality for IntegerLiteral (along with general support for statements and expressions) llvm-svn: 95900

Split DependentNameType into two types. DependentNameType represents the case of an elaborated-type-specifier like 'typename A<T>::foo', and DependentTemplateSpecializationType represents the case of an elaborated-type-specifier like 'typename A<T>::template B<T>'. The TypeLoc representation of a DependentTST conveniently exactly matches that of an ElaboratedType wrapping a TST.

Add a variant of GCC-style vector types for ARM NEON. NEON vector types need to be mangled in a special way to comply with ARM's ABI, similar to some of the AltiVec-specific vector types.

Substantially alter the design of the Objective C type AST by introducing ObjCObjectType, which is basically just a pair of one of {primitive-id, primitive-Class, user-defined @class} with a list of protocols. An ObjCObjectPointerType is therefore just a pointer which always points to one of these types (possibly sugared). ObjCInterfaceType is now just a kind of ObjCObjectType which happens to not carry any protocols. Alter a rather large number of use sites to use ObjCObjectType instead of ObjCInterfaceType. Store an ObjCInterfaceType as a pointer on the decl rather than hashing them in a FoldingSet. Remove some number of methods that are no longer used, at least after this patch. By simplifying ObjCObjectPointerType, we are now able to easily remove and apply pointers to Objective-C types, which is crucial for a certain kind of ObjC++ metaprogramming common in WebKit. llvm-svn: 103870

Cope with anonymous tags defined within declarators by structurally comparing their types under the assumption that they are equivalent, rather than importing the types and then checking for compatibility. A few minor tweaks here: - Teach structural matching to handle compatibility between function types with prototypes and those without prototypes. - Teach structural matching that an incomplete record decl is the same as any other record decl with the same name. - Keep track of pairs of declarations that we have already checked (but failed to find as structurally matching), so we don't emit diagnostics repeatedly. - When importing a typedef of an anonymous tag, be sure to link the imported tag type to its typedef. With these changes, we survive a repeated import of <stdlib.h> and <stdio.h>. Alas, the ASTNodeImporter is getting a little grotty. llvm-svn: 96298

This patch (thanks to Doug Gregor) fixes a problem where Clang was setting the hasExternalVisibleDecls() bit for all DeclContexts it imported. This caused Clang to make unnecessary calls to findExternalVisibleDecls() when an external AST source was installed. In fact, Clang sometimes interpreted a failure by one of these spurious calls to find a Decl as meaning the Decl didn't exist, even though findExternalLexicalDecls() did locate that decl. This produced amusing errors of the form: - error: no member named 'b' in 'A'; did you mean 'b'? - Now, if hasExternalVisibleDecls() or hasExternalLexicalDecls() should be set, the external AST source must do so itself. llvm-svn: 135824

Plug a long standing memory leak in TemplateArgument. The integral APSInt value is now stored in a decomposed form and the backing store for large values is allocated via the ASTContext. This way its not leaked as TemplateArguments are never destructed when they are allocated in the ASTContext. Since the integral data is immutable it is now shared between instances, making copying TemplateArguments a trivial operation. Currently getting the integral data out of a TemplateArgument requires creating a new APSInt object. This is cheap when the value is small but can be expensive if it's not. If this turns out to be an issue a more efficient accessor could be added. llvm-svn: 158150

I added a new function to DeclContext called addDeclInternal(). This function suppresses any calls to FindExternalVisibleDeclsByName() while a Decl is added to a DeclContext. This behavior is required for the ASTImporter, because in the case of the LLDB client the ASTImporter would be called recursively to import the visible decls, which leads to assertions because the recursive call is seeing partially-formed types. I also modified the ASTImporter to use addDeclInternal() in all places where it would otherwise use addDecl().

I added a new function to DeclContext called addDeclInternal(). This function suppresses any calls to FindExternalVisibleDeclsByName() while a Decl is added to a DeclContext. This behavior is required for the ASTImporter, because in the case of the LLDB client the ASTImporter would be called recursively to import the visible decls, which leads to assertions because the recursive call is seeing partially-formed types. I also modified the ASTImporter to use addDeclInternal() in all places where it would otherwise use addDecl(). This fix should not affect the rest of Clang, passes Clang's testsuite, and fixes several serious LLDB bugs. llvm-svn: 142634

Cope with anonymous tags defined within declarators by structurally comparing their types under the assumption that they are equivalent, rather than importing the types and then checking for compatibility. A few minor tweaks here: - Teach structural matching to handle compatibility between function types with prototypes and those without prototypes. - Teach structural matching that an incomplete record decl is the same as any other record decl with the same name. - Keep track of pairs of declarations that we have already checked (but failed to find as structurally matching), so we don't emit diagnostics repeatedly. - When importing a typedef of an anonymous tag, be sure to link the imported tag type to its typedef. With these changes, we survive a repeated import of <stdlib.h> and <stdio.h>. Alas, the ASTNodeImporter is getting a little grotty. llvm-svn: 96298

I added a new function to DeclContext called addDeclInternal(). This function suppresses any calls to FindExternalVisibleDeclsByName() while a Decl is added to a DeclContext. This behavior is required for the ASTImporter, because in the case of the LLDB client the ASTImporter would be called recursively to import the visible decls, which leads to assertions because the recursive call is seeing partially-formed types. I also modified the ASTImporter to use addDeclInternal() in all places where it would otherwise use addDecl(). This fix should not affect the rest of Clang, passes Clang's testsuite, and fixes several serious LLDB bugs. llvm-svn: 142634

Cope with anonymous tags defined within declarators by structurally comparing their types under the assumption that they are equivalent, rather than importing the types and then checking for compatibility. A few minor tweaks here: - Teach structural matching to handle compatibility between function types with prototypes and those without prototypes. - Teach structural matching that an incomplete record decl is the same as any other record decl with the same name. - Keep track of pairs of declarations that we have already checked (but failed to find as structurally matching), so we don't emit diagnostics repeatedly. - When importing a typedef of an anonymous tag, be sure to link the imported tag type to its typedef.

Cope with anonymous tags defined within declarators by structurally comparing their types under the assumption that they are equivalent, rather than importing the types and then checking for compatibility. A few minor tweaks here: - Teach structural matching to handle compatibility between function types with prototypes and those without prototypes. - Teach structural matching that an incomplete record decl is the same as any other record decl with the same name. - Keep track of pairs of declarations that we have already checked (but failed to find as structurally matching), so we don't emit diagnostics repeatedly. - When importing a typedef of an anonymous tag, be sure to link the imported tag type to its typedef. With these changes, we survive a repeated import of <stdlib.h> and <stdio.h>. Alas, the ASTNodeImporter is getting a little grotty. llvm-svn: 96298

constexpr handling improvements. Produce detailed diagnostics when a 'constexpr' variable is initialized by a non-constant expression, and pass in the variable being declared so that earlier-initialized fields' values can be used. Rearrange VarDecl init evaluation to make this possible, and in so doing fix a long-standing issue in our C++ constant expression handling, where we would mishandle cases like: extern const int a; const int n = a; const int a = 5; int arr[n]; Here, n is not initialized by a constant expression, so can't be used in an ICE, even though the initialization expression would be an ICE if it appeared later in the TU.

I added a new function to DeclContext called addDeclInternal(). This function suppresses any calls to FindExternalVisibleDeclsByName() while a Decl is added to a DeclContext. This behavior is required for the ASTImporter, because in the case of the LLDB client the ASTImporter would be called recursively to import the visible decls, which leads to assertions because the recursive call is seeing partially-formed types. I also modified the ASTImporter to use addDeclInternal() in all places where it would otherwise use addDecl(). This fix should not affect the rest of Clang, passes Clang's testsuite, and fixes several serious LLDB bugs. llvm-svn: 142634

I added a new function to DeclContext called addDeclInternal(). This function suppresses any calls to FindExternalVisibleDeclsByName() while a Decl is added to a DeclContext. This behavior is required for the ASTImporter, because in the case of the LLDB client the ASTImporter would be called recursively to import the visible decls, which leads to assertions because the recursive call is seeing partially-formed types. I also modified the ASTImporter to use addDeclInternal() in all places where it would otherwise use addDecl(). This fix should not affect the rest of Clang, passes Clang's testsuite, and fixes several serious LLDB bugs. llvm-svn: 142634

I added a new function to DeclContext called addDeclInternal(). This function suppresses any calls to FindExternalVisibleDeclsByName() while a Decl is added to a DeclContext. This behavior is required for the ASTImporter, because in the case of the LLDB client the ASTImporter would be called recursively to import the visible decls, which leads to assertions because the recursive call is seeing partially-formed types. I also modified the ASTImporter to use addDeclInternal() in all places where it would otherwise use addDecl(). This fix should not affect the rest of Clang, passes Clang's testsuite, and fixes several serious LLDB bugs. llvm-svn: 142634

I added a new function to DeclContext called addDeclInternal(). This function suppresses any calls to FindExternalVisibleDeclsByName() while a Decl is added to a DeclContext. This behavior is required for the ASTImporter, because in the case of the LLDB client the ASTImporter would be called recursively to import the visible decls, which leads to assertions because the recursive call is seeing partially-formed types. I also modified the ASTImporter to use addDeclInternal() in all places where it would otherwise use addDecl(). This fix should not affect the rest of Clang, passes Clang's testsuite, and fixes several serious LLDB bugs. llvm-svn: 142634

Add an optional field attached to a DeclRefExpr which points back to the Decl actually found via name lookup & overload resolution when that Decl is different from the ValueDecl which is actually referenced by the expression. This can be used by AST consumers to correctly attribute references to the spelling location of a using declaration, and otherwise gain insight into the name resolution performed by Clang. The public interface to DRE is kept as narrow as possible: we provide a getFoundDecl() which always returns a NamedDecl, either the ValueDecl referenced or the new, more precise NamedDecl if present. This way AST clients can code against getFoundDecl without know when exactly the AST has a split representation. For an example of the data this provides consider: % cat x.cc namespace N1 { struct S {}; void f(const S&); } void test(N1::S s) { f(s); using N1::f; f(s); } % ./bin/clang -fsyntax-only -Xclang -ast-dump x.cc [...] void test(N1::S s) (CompoundStmt 0x5b02010 <x.cc:5:20, line:9:1> (CallExpr 0x5b01df0 <line:6:3, col:6> 'void' (ImplicitCastExpr 0x5b01dd8 <col:3> 'void (*)(const struct N1::S &)' <FunctionToPointerDecay> (DeclRefExpr 0x5b01d80 <col:3> 'void (const struct N1::S &)' lvalue Function 0x5b01a20 'f' 'void (const struct N1::S &)')) (ImplicitCastExpr 0x5b01e20 <col:5> 'const struct N1::S' lvalue <NoOp> (DeclRefExpr 0x5b01d58 <col:5> 'N1::S':'struct N1::S' lvalue ParmVar 0x5b01b60 's' 'N1::S':'struct N1::S'))) (DeclStmt 0x5b01ee0 <line:7:3, col:14> 0x5b01e40 "UsingN1::;") (CallExpr 0x5b01fc8 <line:8:3, col:6> 'void' (ImplicitCastExpr 0x5b01fb0 <col:3> 'void (*)(const struct N1::S &)' <FunctionToPointerDecay> (DeclRefExpr 0x5b01f80 <col:3> 'void (const struct N1::S &)' lvalue Function 0x5b01a20 'f' 'void (const struct N1::S &)' (UsingShadow 0x5b01ea0 'f'))) (ImplicitCastExpr 0x5b01ff8 <col:5> 'const struct N1::S' lvalue <NoOp> (DeclRefExpr 0x5b01f58 <col:5> 'N1::S':'struct N1::S' lvalue ParmVar 0x5b01b60 's' 'N1::S':'struct N1::S')))) Now we can tell that the second call is 'using' (no pun intended) the using declaration, and *which* using declaration it sees. Without this, we can mistake calls that go through using declarations for ADL calls, and have no way to attribute names looked up with using declarations to the appropriate UsingDecl. llvm-svn: 130670

Avoids a separate allocation and another word of overhead in cases needing inheritance paths.

Introduce a new kind of TemplateName that captures a substituted template template parameter pack that cannot be fully expanded because its enclosing pack expansion could not be expanded. This form of TemplateName plays the same role as SubstTemplateTypeParmPackType and SubstNonTypeTemplateParmPackExpr do for template type parameter packs and non-type template parameter packs, respectively. We should now handle these multi-level pack expansion substitutions anywhere. The largest remaining gap in our variadic-templates support is that we cannot cope with non-type template parameter packs whose type is a pack expansion. llvm-svn: 123521

Implement basic importing and merging of variable declarations within the AST importer. This doesn't actually do anything (yet), because we don't have driver logic for merging ASTs. llvm-svn: 95570

Make sure that imported definitions get completed before we add anything into the corresponding DeclContext. Co-hacked with Sean; fixes <rdar://problem/10768928>. llvm-svn: 149535

Cope with anonymous tags defined within declarators by structurally comparing their types under the assumption that they are equivalent, rather than importing the types and then checking for compatibility. A few minor tweaks here: - Teach structural matching to handle compatibility between function types with prototypes and those without prototypes. - Teach structural matching that an incomplete record decl is the same as any other record decl with the same name. - Keep track of pairs of declarations that we have already checked (but failed to find as structurally matching), so we don't emit diagnostics repeatedly. - When importing a typedef of an anonymous tag, be sure to link the imported tag type to its typedef. With these changes, we survive a repeated import of <stdlib.h> and <stdio.h>. Alas, the ASTNodeImporter is getting a little grotty. llvm-svn: 96298
