* Cope with anonymous tags defined within declarators by structurallyDouglas Gregor2010-02-156-1/+29
| | | | | | | | | | | | | | | | | | | | 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
* Reimplement the structural-equality checks used to determine whetherDouglas Gregor2010-02-152-3/+13
| | | | | | | | | | | | | | two types in different AST contexts are equivalent. Rather than transforming the type from one context into the other context, we perform a deep structural comparison of the types. This change addresses a serious problem with recursive data types like struct ListNode { int value; struct ListNode *Next; } xList; llvm-svn: 96278

| | | | | | | | | | | | | | | | | | | | | | | | | | 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

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.
