* [Dsymutil][Debuginfo][NFC] #3 Refactor dsymutil to separate DWARF optimizing ↵Alexey Lapshin2020-01-131-26/+44
| | | | | | | | | | | | | | | | | | | | | | | | part. Summary: This is the next portion of patches for dsymutil. Create DwarfEmitter interface to generate all debug info tables. Put DwarfEmitter into DwarfLinker library and make tools/dsymutil/DwarfStreamer to be child of DwarfEmitter. It passes check-all testing. MD5 checksum for clang .dSYM bundle matches for the dsymutil with/without that patch.

* [Dsymutil][Debuginfo][NFC] Reland: Refactor dsymutil to separate DWARF ↵Alexey Lapshin2020-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | optimizing part. #2. Summary: This patch relands D71271. The problem with D71271 is that it has cyclic dependency: CodeGen->AsmPrinter->DebugInfoDWARF->CodeGen. To avoid cyclic dependency this patch puts implementation for DWARFOptimizer into separate library: lib/DWARFLinker. Thus the difference between this patch and D71271 is in that DWARFOptimizer renamed into DWARFLinker and it`s files are put into lib/DWARFLinker.

| | | | | | | | | | | part 2. That patch is extracted from the D70709. It moves CompileUnit, DeclContext into llvm/DebugInfo/DWARF. It also adds new file DWARFOptimizer with AddressesMap class. AddressesMap generalizes functionality from RelocationManager. Differential Revision: https://reviews.llvm.org/D71271
* [Dsymutil][NFC] Move NonRelocatableStringpool into common CodeGen folder.Alexey Lapshin2019-12-061-1/+1
| | | | | | | That refactoring moves NonRelocatableStringpool into common CodeGen folder. So that NonRelocatableStringpool could be used not only inside dsymutil. Differential Revision: https://reviews.llvm.org/D71068
* Switch LLVM to use 64-bit offsets (2/5)Igor Kudrin2019-08-061-3/+3
| | | | | | | | | This updates all libraries and tools in LLVM Core to use 64-bit offsets which directly or indirectly come to DataExtractor. Differential Revision: https://reviews.llvm.org/D65638 llvm-svn: 368014
* [Dsymutil] Remove redundant argument (NFC)Jonas Devlieghere2019-05-211-2/+1

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

* [DWARF] Revert r345546: Refactor range list extraction and dumpingWolfgang Pieb2018-10-311-2/+2
| | | | | | This patch caused some internal tests to break which are being investigated. llvm-svn: 345687
* [DWARF][NFC] Refactor range list extraction and dumpingWolfgang Pieb2018-10-291-2/+2
| | | | | | | | | | | | | | | | | The purpose of this patch is twofold: - Fold pre-DWARF v5 functionality into v5 to eliminate the need for 2 different versions of range list handling. We get rid of DWARFDebugRangelist{.cpp,.h}. - Templatize the handling of range list tables so that location list handling can take advantage of it as well. Location list and range list tables have the same basic layout. A non-NFC version of this patch was previously submitted with r342218, but it caused errors with some TSan tests. This patch has no functional changes. The difference to the non-NFC patch is that there are no changes to rangelist dumping in this patch.

| | | | | | | Also adjust some of dsymutil's headers to put the header guards at the top, otherwise the compiler will not recognize them as header guards. llvm-svn: 341323
* [dsymutil] Add support for generating DWARF5 accelerator tables.Jonas Devlieghere2018-07-251-0/+11
| | | | | | | | | | | | | | | | | | This patch add support for emitting DWARF5 accelerator tables (.debug_names) from dsymutil. Just as with the Apple style accelerator tables, it's possible to update existing dSYMs. This patch includes a test that show how you can convert back and forth between the two types. If no kind of table is specified, dsymutil will default to generating Apple-style accelerator tables whenever it finds those in its input. The same is true when there are no accelerator tables at all. Finally, in the remaining case, where there's at least one DWARF v5 table and no Apple ones, the output will contains a DWARF accelerator tables (.debug_names).

* [dsymutil] Add support for outputting assemblyJonas Devlieghere2018-07-091-4/+8
| | | | | | | | | | | | | When implementing the DWARF accelerator tables in dsymutil I ran into an assertion in the assembler. Debugging these kind of issues is a lot easier when looking at the assembly instead of debugging the assembler itself. Since it's only a matter of creating an AsmStreamer instead of a MCObjectStreamer it made sense to turn this into a (hidden) dsymutil feature.

* [dsymutil] Move abstractions into separate files (NFC)Jonas Devlieghere2018-06-271-0/+171
This patch splits off some abstractions used by dsymutil's dwarf linker and moves them into separate header and implementation files. This almost halves the number of LOC in DwarfLinker.cpp and makes it a lot easier to understand what functionality lives where. Differential revision: https://reviews.llvm.org/D48647 llvm-svn: 335749
