* DebugInfo: Adapt to loss of DITypeRef in LLVM r267296Duncan P. N. Exon Smith2016-04-231-21/+23
| | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@267297 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Make DICompositeTypes distinct most of the timeDuncan P. N. Exon Smith2016-04-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@266556 91177308-0d34-0410-b5e6-96231b3b80d8

* Stop messing with the 'g' group of options in CompilerInvocation.Douglas Katzman2015-10-081-2/+1
| | | | | | | | | | | | | | | | 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.

* DebugInfo: Metadata constructs now start with DI*Duncan P. N. Exon Smith2015-04-291-14/+14
| | | | | | | | | | LLVM r236120 renamed debug info IR constructs to use a `DI` prefix, now that the `DIDescriptor` hierarchy has been gone for about a week.

Newer (4.8.1 and ToT) GCC's don't produce this quirky debug info, and instead produce the full definition for the outer type (except in the case where that type is dynamic and its vtable is not emitted in this TU). During the creation of the context for a type, we may revisit that type (due to the need to visit template parameters, among other things) and used to end up visiting it first there. Then when we would reach the original code attempting to define that type, we would lose debug info by overwriting its members. By avoiding the possibility of latent "defined with no members" types, we can be sure than whenever we already have a type in a cache (either a definition or declaration), we can just return that. In the case of a full definition, our work is done. In the case of a partial definition, we must already be in the process of completing it. And in the case of a declaration, the completed/vtable/etc callbacks can handle converting it to a definition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@190122 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: generate a unique identifier for C++ struct, class, union, and enum.Manman Ren2013-08-291-8/+10
| | | | | | | | | | | | | | | | | We use CXX mangler to generate unique identifier for external C++ struct, union, class and enum. Types with unique identifier are added to retained types by DIBuilder. Testing cases are updated to reflect the unique identifier generated for types. The order of MDNodes is changed because of retained types and testing cases are updated accordingly. Testing case debug-info-uuid.cpp now emits error with Itanium mangler, since uuid is not yet handled in Itanium mangler. And it will check for the error message. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@189622 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | We use CXX mangler to generate unique identifier for external C++ struct, union, class and enum. Types with unique identifier are added to RetainedTypes to make sure they are treated as used even when all uses are replaced with the identifiers. A single type can be added to RetainedTypes multiple times. For example, both createForwardDecl and createLimitedType can add the same type to RetainedTypes. A set is used to avoid duplication when updating AllRetainTypes in DIBuilder. Testing cases are updated to reflect the unique identifier generated for types. The order of MDNodes is changed because of retained types and testing cases are updated accordingly. Testing case debug-info-uuid.cpp now emits error with Itanium mangler, since uuid is not yet handled in Itanium mangler. We choose to update RetainedTypes in clang, then at finalize(), we update AllRetainTypes in DIBuilder. The other choice is to update AllRetainTypes in DIBuilder when creating a DICompositeType with unique identifier. This option requires using ValueHandle for AllRetainTypes in DIBuilder since the created DICompositeType can be modified later on by setContainingType etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@189600 91177308-0d34-0410-b5e6-96231b3b80d8
