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)
