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) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95900 91177308-0d34-0410-b5e6-96231b3b80d8
