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

Don't cache the artificial type for the this pointer, there's no difference in the qual type. This is a workaround for the fact that the type isn't artificial but the this decl is, however, we don't have any way of representing it in the current metadata. For now, however, just don't cache the full type. Fixes rdar://10831526 and probably a couple of others. llvm-svn: 150159

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

DebugInfo: Adapt to loss of DITypeRef in LLVM r267296 LLVM stopped using MDString-based type references, and DIBuilder no longer fills 'retainedTypes:' with every DICompositeType that has an 'identifier:' field. There are just minor changes to keep the same behaviour in CFE. Leaving 'retainedTypes:' unfilled has a dramatic impact on the output order of the IR though. There are a huge number of testcase changes, which were unfortunately not really scriptable. llvm-svn: 267297

DebugInfo: Metadata constructs now start with DI* LLVM r236120 renamed debug info IR constructs to use a `DI` prefix, now that the `DIDescriptor` hierarchy has been gone for about a week. This commit was generated using the rename-md-di-nodes.sh upgrade script attached to PR23080, followed by running clang-format-diff.py on the `lib/` portion of the patch. llvm-svn: 236121
