Module Debugging: Emit forward declarations for types that are defined in clang modules, if -dwarf-ext-refs (DebugTypesExtRefs) is specified. This reimplements r247369 in about a third of the amount of code. Thanks to David Blaikie pointing this out in post-commit review! llvm-svn: 247432

// Modules:
Stop messing with the 'g' group of options in CompilerInvocation. With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation. Also fix a bug in the Windows compatibility argument parsing in which the "rightmost argument wins" principle failed. Differential Revision: http://reviews.llvm.org/D13221 llvm-svn: 249655

DebugInfo: Make DICompositeTypes distinct most of the time Since elements of most kinds of DICompositeType have back references, most are involved in uniquing cycles. Except via the ODR 'identifier:' field, which doesn't care about the storage type (see r266549), they have no hope of being uniqued. Distinct nodes are far more efficient, so use them for most kinds of DICompositeType definitions (i.e., when DIType::isForwardDecl is false). The exceptions: - DW_TAG_array_type, since their elements never have back-references and they never have ODR 'identifier:' fields; - DW_TAG_enumeration_type when there is no ODR 'identifier:' field, since their elements usually don't have back-references. This breaks the last major uniquing cycle I'm aware of in the debug info graph. The impact won't be enormous for C++ because references to ODR-uniqued nodes still use string-based DITypeRefs; but this should prevent a regression in C++ when we drop the string-based references. This wouldn't have been reasonable until r266549, when composite types stopped relying on being uniqued by structural equivalence to prevent blow-ups at LTO time. llvm-svn: 266556
