Add a helper function getDebugInfoVersionFromModule to return the debug info version number for a module. "Verifier/module-flags-1.ll" checks for verification errors. It will seg fault when calling getDebugInfoVersionFromModule because of the incorrect format for module flags in the testing case. We make getModuleFlagsMetadata more robust by checking for error conditions.

| | | | | | | | | | | We used to depend on running processModule before the other public functions such as processDeclare, processValue and processLocation. We are now relaxing the constraint by adding a module argument to the three functions and letting the three functions to initialize the type map.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | is updated to use DITypeRef. Move isUnsignedDIType and getOriginalTypeSize from DebugInfo.h to be static helper functions in DwarfCompileUnit. We already have a static helper function "isTypeSigned" in DwarfCompileUnit, and a pointer to DwarfDebug is added to resolve the derived-from field. All three functions need to go across link for derived-from fields, so we need to get hold of a type identifier map. A pointer to DwarfDebug is also added to DbgVariable in order to resolve the derived-from field. Debug info verifier is updated to check a derived-from field is a TypeRef. Verifier will not go across link for derived-from fields, in debug info finder, we go across the link to add derived-from fields to types. Function getDICompositeType is only used by dragonegg and since dragonegg does not generate identifier for types, we use an empty map to resolve the derived-from field. When printing a derived-from field, we use DITypeRef::getName to either return the type identifier or getName of the DIType.

* Debug Info: move class definition of DIRef.Manman Ren2013-09-11
| | | | | | | | | | | | Definition of DIRef used to require the full definition of DIType because of usage of DIType::isType in DIRef::resolve. We now use DIDescriptor::isType instead to remove the requirement and move definition of DIRef before DIType. With this, we can move the definition of DIType::getContext to the header file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190540 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: define a DIRef template.Manman Ren2013-09-10
| | | | | | | | | | | | | | Specialize the constructors for DIRef<DIScope> and DIRef<DIType> to make sure the Value is indeed a scope ref and a type ref. Use DIScopeRef for DIScope::getContext and DIType::getContext and use DITypeRef for getContainingType and getClassType. DIScope::generateRef now returns a DIScopeRef instead of a "Value *" for readability and type safety. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190418 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: move DIScope::getContext back from DwarfDebug.Manman Ren2013-09-09
| | | | | | | | | This partially reverts r190330. DIScope::getContext now returns DIScopeRef instead of DIScope. We construct a DIScopeRef from DIScope when we are dealing with subprogram, lexical block or name space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190362 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: Use DIScopeRef for DIType::getContext.Manman Ren2013-09-09
| | | | | | | | | | | | | | | | | | In DIBuilder, the context field of a TAG_member is updated to use the scope reference. Verifier is updated accordingly. DebugInfoFinder now needs to generate a type identifier map to have access to the actual scope. Same applies for BreakpointPrinter. processModule of DebugInfoFinder is called during initialization phase of the verifier to make sure the type identifier map is constructed early enough. We are now able to unique a simple class as demonstrated by the added testing case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190334 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: move DIScope::getContext to DwarfDebug.Manman Ren2013-09-09
| | | | | | | | | | | | | DIScope::getContext is a wrapper function that calls the specific getContext method on each subclass. When we switch DIType::getContext to return DIScopeRef instead of DIScope, DIScope::getContext can no longer return a DIScope without a type identifier map. DIScope::getContext is only used by DwarfDebug, so we move it to DwarfDebug to have easy access to the type identifier map. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190330 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: Move isSubprogramContext from DebugInfo to DwarfDebug.Manman Ren2013-09-09
| | | | | | | | | | | This helper function needs the type identifier map when we switch DIType::getContext to return DIScopeRef instead of DIScope. Since isSubprogramContext is used by DwarfDebug only, We move it to DwarfDebug to have easy access to the map. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190325 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: Rename DITypeRef to DIScopeRef.Manman Ren2013-09-09
| | | | | | | | | | | | | | | | | | | | | | | A reference to a scope is more general than a reference to a type since DIType is a subclass of DIScope. A reference to a type can be either an identifier for the type or the DIType itself, while a reference to a scope can be either an identifier for the type (when the scope is indeed a type) or the DIScope itself. A reference to a type and a reference to a scope will be resolved in the same way. The only difference is in the verifier when a field is a reference to a type (i.e. the containing type field of a DICompositeType) or a field is a reference to a scope (i.e. the context field of a DIType). This is to get ready for switching DIType::getContext to return DIScopeRef instead of DIScope. Tighten up isTypeRef and isScopeRef to make sure the identifier is not empty and the MDNode is DIType for TypeRef and DIScope for ScopeRef. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190322 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info: Use identifier to reference DIType in base type field ofManman Ren2013-09-05
| | | | | | | | | | | | | | | | | | | | | | | ptr_to_member. We introduce a new class DITypeRef that represents a reference to a DIType. It wraps around a Value*, which can be either an identifier in MDString or an actual MDNode. The class has a helper function "resolve" that finds the actual MDNode for a given DITypeRef. We specialize getFieldAs to return a field that is a reference to a DIType. To correctly access the base type field of ptr_to_member, getClassType now calls getFieldAs<DITypeRef> to return a DITypeRef. Also add a typedef for DITypeIdentifierMap and a helper generateDITypeIdentifierMap in DebugInfo.h. In DwarfDebug.cpp, we keep a DITypeIdentifierMap and call generateDITypeIdentifierMap to actually populate the map. Verifier is updated accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190081 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info: add an identifier field to DICompositeType.Manman Ren2013-08-26
| | | | | | | | | | | | | | | | | | | DICompositeType will have an identifier field at position 14. For now, the field is set to null in DIBuilder. For DICompositeTypes where the template argument field (the 13th field) was optional, modify DIBuilder to make sure the template argument field is set. Now DICompositeType has 15 fields. Update DIBuilder to use NULL instead of "i32 0" for null value of a MDNode. Update verifier to check that DICompositeType has 15 fields and the last field is null or a MDString. Update testing cases to include an extra field for DICompositeType. The identifier field will be used by type uniquing so a front end can genearte a DICompositeType with a unique identifer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189282 91177308-0d34-0410-b5e6-96231b3b80d8
