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)

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.

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;
^

/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
that we get readable diagnostics such as:
error: external variable 'x1' declared with incompatible types in
different translation units ('double *' vs. 'float **')
However, there is no translation of source locations, yet.
