| | | | | | | Use definition file for `DW_VIRTUALITY_*`. Add a `DW_VIRTUALITY_max` both for ease of testing and for future use by the `LLParser`. llvm-svn: 228473

* Support: Add string => unsigned mapping for DW_TAGDuncan P. N. Exon Smith2015-02-031-0/+8
| | | | | | Add `dwarf::getTag()` to translate from `StringRef` to `unsigned`. llvm-svn: 228031
* Support: Re-implement dwarf::TagString() using a .def file, NFCDuncan P. N. Exon Smith2015-02-031-78/+5
| | | | | | | | | Also re-implements the `dwarf::Tag` enumerator. I've moved the mock tags into the enumerator since there's no other way to do this. Really they shouldn't be used at all (they're just a hack to identify `MDNode`s, but we have a class hierarchy for that now). llvm-svn: 228030
* Support: Stop stringifying DW_TAG_{lo,hi}_userDuncan P. N. Exon Smith2015-02-031-2/+0
| | | | | | | | `dwarf::TagString()` shouldn't stringify `DW_TAG_lo_user` or `DW_TAG_hi_user`. These aren't actual tags; they're markers for the edge of vendor-specific tag regions. llvm-svn: 228029
* Modernize doxygen comments in Support/Dwarf.hFrederic Riss2014-10-231-45/+0
| | | | | | | | | | In post-commit review of r219442, Rafael pointed out that the comment style of the newly introduced helper didn't follow LLVM's coding standard. Modernize the whole file to the new standards. Differential Revision: http://reviews.llvm.org/D5918 llvm-svn: 220467

* Move the complex address expression out of DIVariable and into an extraAdrian Prantl2014-10-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | argument of the llvm.dbg.declare/llvm.dbg.value intrinsics. Previously, DIVariable was a variable-length field that has an optional reference to a Metadata array consisting of a variable number of complex address expressions. In the case of OpPiece expressions this is wasting a lot of storage in IR, because when an aggregate type is, e.g., SROA'd into all of its n individual members, the IR will contain n copies of the DIVariable, all alike, only differing in the complex address reference at the end. By making the complex address into an extra argument of the dbg.value/dbg.declare intrinsics, all of the pieces can reference the same variable and the complex address expressions can be uniqued across the CU, too. Down the road, this will allow us to move other flags, such as "indirection" out of the DIVariable, too. The new intrinsics look like this: declare void @llvm.dbg.declare(metadata %storage, metadata %var, metadata %expr) declare void @llvm.dbg.value(metadata %storage, i64 %offset, metadata %var, metadata %expr) This patch adds a new LLVM-local tag to DIExpressions, so we can detect and pretty-print DIExpression metadata nodes. What this patch doesn't do: This patch does not touch the "Indirect" field in DIVariable; but moving that into the expression would be a natural next step. http://reviews.llvm.org/D4919 rdar://problem/17994491 Thanks to dblaikie and dexonsmith for reviewing this patch! Note: I accidentally committed a bogus older version of this patch previously. llvm-svn: 218787

* Unshift the GDB index/GNU pubnames constants modified in r191025David Blaikie2013-09-191-23/+0
| | | | | | | | | | | | Based on code review feedback from Eric Christopher, unshifting these constants as they can appear in the gdb_index itself, shifted a further 24 bits. This means that keeping them preshifted is a bit inflexible, so let's not do that. Given the motivation, wrap up some nicer enums, more type safety, and some utility functions. llvm-svn: 191035

To keep it manageable, the patch omits some more advanced capabilities (accounted in TODOs): * Parsing of instructions with BLOCK arguments (expression lists) * Dumping of actual instruction arguments (currently only names are dumped). This is quite tricky since the dumper has to effectively "interpret" the instructions. llvm-svn: 175820
