================
Comment at: clang/lib/Serialization/ASTWriterDecl.cpp:2313
void ASTDeclWriter::VisitOMPDeclareMapperDecl(OMPDeclareMapperDecl *D) {
+ static_assert(sizeof(OMPDeclareMapperDecl) == 120,
+ "You need to update the serializer after you change the fields "
----------------
How can this work? This includes an ArrayRef (http://llvm-cs.pcc.me.uk/tools/clang/include/clang/AST/DeclOpenMP.h#221) which contains a pointer and a size_t. That alone will be 16 bytes on 64-bit builds and 8 bytes on 32-bit builds.
