Push a new scope for constructs and statements that require one (DataStmt, DO CONCURRENT, ForallConstruct, ForallStmt -- there are more to do). Currently we use the Block kind of scope because there is no difference. Perhaps that kind should be renamed to Construct, though it does apply to statements as well as constructs. Add DeclareConstructEntity to create a construct or statement entity. When the type is not specified it can come from the type of a symbol in the enclosing scope with the same name. Change DeclareObjectEntity et al. to return the symbol declared, for the benefit of DeclareConstructEntity. Use DeclareConstructEntity for DO CONCURRENT index-name, LOCAL, and LOCAL_INIT variables and the data-i-do-variable in DataImpliedDo Names in SHARED locality spec need special handling: create a new kinds of symbol with HostAssocDetails to represent the host-association of the shared variables within the construct scope. That symbol gets the LocalityShared flag without affecting the symbol in the outer scope. HostAssoc symbols may be useful in other contexts, e.g. up-level references to local variables. Add parser::DoConstruct::IsDoConcurrent() because DO CONCURRENT loops introduce a construct scope while other DO loops do not. Move CanonicalizeDo to before name resolution so that name resolution doesn't have to deal with labeled DO CONCURRENT loops. Allow for type of index name to be specified in ConcurrentHeader. Resolve the derived type name in an AllocateStmt, StructureConstructor Original-commit: flang-compiler/f18@bc7b989136 Reviewed-on: https://github.com/flang-compiler/f18/pull/214 |
