* DebugInfo: provide the ability to add members to a class after it has been ↵David Blaikie2013-08-091-0/+1
| | | | | | | | | | constructed This is necessary to allow Clang to only emit implicit members when there is code generated for them, rather than whenever they are ODR used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188082 91177308-0d34-0410-b5e6-96231b3b80d8

* Debug Info Finder|Verifier: handle DbgLoc attached to instructions.Manman Ren2013-08-061-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also remove checking of llvm.dbg.sp since it is not used in generating dwarf. Current state of Finder: DebugInfoFinder tries to list all debug info MDNodes used in a module. To list debug info MDNodes used by an instruction, DebugInfoFinder provides processDeclare, processValue and processLocation to handle DbgDeclareInst, DbgValueInst and DbgLoc attached to instructions. processModule will go through all DICompileUnits in llvm.dbg.cu and list debug info MDNodes used by the CUs. TODO: 1> Finder has a list of CUs, SPs, Types, Scopes and global variables. We need to add a list of variables that are used by DbgDeclareInst and DbgValueInst. 2> MDString fields should be null or isa<MDString> and MDNode fields should be null or isa<MDNode>. We currently use empty string or int 0 to represent null. 3> Go though Verify functions and make sure that they check field types. 4> Clean up existing testing cases to remove llvm.dbg.sp and make sure each testing case has a llvm.dbg.cu. Re-apply r187609 with fix to pass ocaml binding. vmcore.ml generates a debug location with scope being metadata !{}, in verifier we treat this as a null scope. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187812 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | Adding another CU-wide list, in this case of imported_modules (since they should be relatively rare, it seemed better to add a list where each element had a "context" value, rather than add a (usually empty) list to every scope).

* Adding DIImportedModules to DIScopes.David Blaikie2013-03-271-52/+64
| | | | | | | | | | | | This is just the basic groundwork for supporting DW_TAG_imported_module but I wanted to commit this before pushing support further into Clang or LLVM so that this rather churny change is isolated from the rest of the work. The major churn here is obviously adding another field (within the common DIScope prefix) to all DIScopes (files, classes, namespaces, lexical scopes, etc). This should be the last big churny change needed for DW_TAG_imported_module/using directive support/PR14606. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178099 91177308-0d34-0410-b5e6-96231b3b80d8
