Debug Info: In DIBuilder, the derived-from field of a DW_TAG_pointer_type 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. A paired commit at clang is required due to changes to DIBuilder. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192018 91177308-0d34-0410-b5e6-96231b3b80d8 2013-10-05 01:43:03 +00:00			`; REQUIRES: object-emission`

Reland r200340 - 'Add line table debug info to COFF files when using a win32 triple' This incorporates a couple of fixes reviewed at http://llvm-reviews.chandlerc.com/D2651 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200440 91177308-0d34-0410-b5e6-96231b3b80d8 2014-01-30 01:39:17 +00:00			`; RUN: %llc_dwarf -filetype=obj -O0 < %t > %t2`
Debug Info: remove duplication of DIEs when a DIE can be shared across CUs. We add a map in DwarfDebug to map MDNodes that are shareable across CUs to the corresponding DIEs: MDTypeNodeToDieMap. These DIEs can be shared across CUs, that is why we keep the maps in DwarfDebug instead of CompileUnit. We make the assumption that if a DIE is not added to an owner yet, we assume it belongs to the current CU. Since DIEs for the type system are added to their owners immediately after creation, and other DIEs belong to the current CU, the assumption should be true. A testing case is added to show that we only create a single DIE for a type MDNode and we use ref_addr to refer to the type DIE. We also add a testing case to show ref_addr relocations for non-darwin platforms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193779 91177308-0d34-0410-b5e6-96231b3b80d8 2013-10-31 17:54:35 +00:00			`; RUN: llvm-dwarfdump -debug-dump=info %t2 \| FileCheck %S/Inputs/type-unique-simple2-a.ll`
