Manman Ren f40d578d7e Debug Info Finder|Verifier: handle DbgLoc attached to instructions. ... 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		2013-08-06 19:38:43 +00:00
