* [DebugInfo] Improvements to representation of enumeration types (PR36168)Momchil Velikov2018-02-071-1/+1
| | | | | | | | | | | | | | | This patch: * fixes an incorrect sign-extension of unsigned values, when emitting debug info metadata for enumerators * the enumerators metadata is created with a flag, which determines interpretation of the value bits (signed or unsigned) * the enumerations metadata contains the underlying integer type and a flag, indicating whether this is a C++ "fixed enum" Differential Revision: https://reviews.llvm.org/D42736 llvm-svn: 324490
* Stop messing with the 'g' group of options in CompilerInvocation.Douglas Katzman2015-10-081-1/+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. Differential Revision: http://reviews.llvm.org/D13221 llvm-svn: 249655
* DebugInfo: Metadata constructs now start with DI*Duncan P. N. Exon Smith2015-04-291-9/+9
| | | | | | | | | | 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
* DebugInfo: Move new hierarchy into place (clang)Duncan P. N. Exon Smith2015-03-031-9/+19
| | | | | | | Update testcases for LLVM change in r231082 to use the new debug info hierarchy. llvm-svn: 231083

* Revert "Revert "DI: LLVM schema change: fold constants into string""Duncan P. N. Exon Smith2014-10-031-6/+6
| | | | | | | | | | | | | | This reverts commit r218917, effectively reapplying r218913. Original commit message follows. -- Update debug info testcases for an LLVM metadata schema change to fold metadata constant operands into a single `MDString`. Part of PR17891. llvm-svn: 219011

* Reapply: DebugInfo: Emit the definition of enums when the definition ↵David Blaikie2014-05-061-0/+9
| | | | | | | | | | | | | | | | | | | preceeds the declaration and initial use. Reverting r208106 to reapply r208065 with a fix for the regression. The issue was that the enum tried to be built even if the declaration hadn't been constructed for debug info - presenting problems for enum templates and typedefs of enums with names for linkage purposes. Original commit message: This regressed a little further 208055 though it was already a little broken. While the requiresCompleteType optimization should be implemented here. Future (possibly near future) work. llvm-svn: 208114
* Remove the -cxx-abi command-line flag.Hans Wennborg2014-01-141-1/+1
| | | | | | | | | | | | | | | This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

* Debug Info: generate a unique identifier for C++ struct, class, union, and enum.Manman Ren2013-08-291-3/+3
| | | | | | | | | | | | | | | | 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. llvm-svn: 189622
* Debug Info: this reverts commit r189600.Manman Ren2013-08-291-3/+3
| | | | | | | | We had further discussions on how to retain types, whether to do it in front end or in DIBuilder. And we agree to do it in DIBuilder so front ends generating unique identifier do not need to worry about retaining them. llvm-svn: 189609
* Debug Info: generate a unique identifier for C++ struct, class, union, and enum.Manman Ren2013-08-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 189600
* Debug Info: follow-up patch to r189283.Manman Ren2013-08-261-3/+3
| | | | | | | Thanks David for his suggestion. This commit updates testing cases to have more specific CHECKs. llvm-svn: 189286
* Debug Info: add an identifier field to DICompositeType.Manman Ren2013-08-261-3/+3
| | | | | | | Paired with llvm r189282. Update testing cases to handle an extra field for DICompositeType. llvm-svn: 189283
* DebugInfo: ensure negative enumerators are emitted as suchDavid Blaikie2013-06-241-1/+12
| | | | | | | | | | There's still a problem here - since we're not appropriately using the signedness/range of the enum to chooset the encoding and emission of enumerators, but GCC has some bugs around this too so I assume that's not /such/ a high priority though I may get to it soon out of completeness. llvm-svn: 184695
* DebugInfo: Merge a bad debug info enum test into a good oneDavid Blaikie2013-06-241-6/+23
