Raw Normal View History

Introduce a testbed for merging multiple ASTs into a single AST context with the AST importer. WIP, still useless but at least it has a test. llvm-svn: 95683

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. Instead, we map down to the spelling location (for now!). llvm-svn: 95732

Teach AST merging that variables with incomplete array types can be merged with variables of constant array types. Also, make sure that we call DiagnosticClient's BeginSourceFile/EndSourceFile, so that it has a LangOptions to work with. llvm-svn: 95782
