* [obj2yaml] [yaml2obj] Support for MachO nlist and string tableChris Bieneman2016-06-021-0/+11
| | | | | | This commit adds round tripping for MachO symbol data. Symbols are entries in the name list, that contain offsets into the string table which is at the end of the __LINKEDIT segment. llvm-svn: 271604
* [COFF] Expose the PE debug data directory and dump itReid Kleckner2016-06-021-1/+1
| | | | | | | | | | | | This directory is used to find if there is a PDB associated with an executable. I plan to use this functionality to teach llvm-symbolizer whether it should use DIA or DWARF to symbolize a given DLL. Reviewers: majnemer Differential Revision: http://reviews.llvm.org/D20885 llvm-svn: 271539
* [obj2yaml][yaml2obj] Support for reading and dumping the MachO export trieChris Bieneman2016-05-311-0/+19
| | | | | | The MachO export trie is a serially encoded trie keyed by symbol name. This code parses the trie and preserves the structure so that it can be dumped again. llvm-svn: 271300
* [obj2yaml][yaml2obj] Support for MachO lazy bindingsChris Bieneman2016-05-261-0/+1
| | | | | | This adds support for YAML round tripping dyld info lazy bindings. The storage and format of these is the same as regular bind opcodes, they are just interpreted differently by dyld, and can have DONE opcodes in the middle of the opcode lists. llvm-svn: 270920
* [obj2yaml][yaml2obj] Support for MachO weak bindingsChris Bieneman2016-05-261-0/+1
| | | | | | This adds support for YAML round tripping dyld info weak bindings. The storage and format of these is the same as regular bind opcodes, they are just interpreted differently by dyld. llvm-svn: 270911
* [obj2yaml][yaml2obj] Support for MachO bind opcodesChris Bieneman2016-05-261-4/+14
| | | | | | This adds support for YAML round tripping dyld info bind opcodes. Bind opcodes can have signed or unsigned LEB128 data, and they can have symbols associated with them. llvm-svn: 270901
* [obj2yaml] [yaml2obj] MachO support for rebase opcodesChris Bieneman2016-05-251-0/+13
| | | | | | This is the first bit of support for MachO __LINKEDIT segment data. llvm-svn: 270724
* [MachOYAML] Removing duplicated field from LC_UUID YAMLChris Bieneman2016-05-201-1/+0
| | | | | | The uuid_command was duplicating the load_command.cmdsize field. This removes the duplicate from the YAML mapping and from the test cases. llvm-svn: 270248
* [obj2yaml] [yaml2obj] Support for MachO Load Command dataChris Bieneman2016-05-191-4/+30
| | | | | | | | | | | | | | This re-applies r270115. Many of the MachO load commands can have data appended after the command structure. This data is frequently strings, but can actually be anything. This patch adds support for three optional fields on load command yaml descriptions. The new PayloadString YAML field is populated with the data after load commands known to have strings as extra data. The new ZeroPadBytes YAML field is a count of zero'd bytes after the end of the load command structure before the next command. This can apply anywhere in the file. MachO2YAML verifies that bytes are zero before populating this field, and YAML2MachO will add zero'd bytes. The new PayloadBytes YAML field stores all bytes after the end of the load command structure before the next command if they are non-zero. This is a catch all for all unhandled bytes. If MachO2Yaml populates PayloadBytes it will not populate ZeroPadBytes, instead zero'd bytes will be in the PayloadBytes structure. llvm-svn: 270124
* Revert "[obj2yaml] [yaml2obj] Support for MachO Load Command data"Chris Bieneman2016-05-191-30/+4
| | | | | | | | This reverts commit r270115. This failed on several builders using GCC. llvm-svn: 270121

* Re-apply: [obj2yaml] [yaml2obj] Support MachO section and section_64Chris Bieneman2016-05-181-4/+27
| | | | | | This re-applies r269845, r269846, and r269850 with an included fix for a crash reported by zturner. llvm-svn: 269953
* Revert "[obj2yaml] [yaml2obj] Support MachO section and section_64Zachary Turner2016-05-171-24/+2
| | | | | | | | | structs" This reverts commits r269845, r269846, and r269850 as they introduce a crash in obj2yaml when trying to do a roundtrip. llvm-svn: 269865
* [obj2yaml][yaml2obj] Fixing dyld_info_command mappingsChris Bieneman2016-05-171-2/+4
| | | | | | Apparently I mucked up the mappings here, which was causing some binary differences in round tripping. llvm-svn: 269846
* [obj2yaml] [yaml2obj] Support MachO section and section_64 structsChris Bieneman2016-05-171-0/+20
| | | | | | This patch adds round trip support for MachO section structs. llvm-svn: 269845
* Reapply r269782 "[obj2yaml] [yaml2obj] Support for MachO load command ↵Chris Bieneman2016-05-171-6/+353
| | | | | | | | structures"" This adds support for all the MachO *_command structures. The load_command payloads still are not represented, but that will come next. llvm-svn: 269808
* Revert "[obj2yaml] [yaml2obj] Support for MachO load command structures"Chris Bieneman2016-05-171-354/+6
| | | | | | This reverts commit r269782 because it broke bots with -fpermissive. llvm-svn: 269785
* [obj2yaml] [yaml2obj] Support for MachO load command structuresChris Bieneman2016-05-171-6/+354
| | | | | | This adds support for all the MachO *_command structures. The load_command payloads still are not represented, but that will come next. llvm-svn: 269782
* [obj2yaml] [yaml2obj] Basic support for MachO::load_commandChris Bieneman2016-05-131-0/+11
| | | | | | | | This patch adds basic support for MachO::load_command. Load command types and sizes are encoded in the YAML and expanded back into MachO. The YAML doesn't yet support load command structs, that is coming next. In the meantime as a temporary measure when writing MachO files the load commands are padded with zeros so that the generated binary is valid. llvm-svn: 269442
* [yaml2macho] Handle mach_header_64 reserved fieldChris Bieneman2016-05-121-0/+2
| | | | | | I've added the reserved field as an "optional" in YAML, but I've added asserts in the yaml2macho code to enforce that the field is present in mach_header_64, but not in mach_header. llvm-svn: 269320
* [ObjectYAML] filetype is a required field in MachO headersChris Bieneman2016-05-121-1/+1
| | | | | | Not sure how I managed to copy-pasta this wrong, but I did. llvm-svn: 269317
* [obj2yaml] Include all mach_header fields in yamlChris Bieneman2016-05-121-1/+3
| | | | | | Since we want to be able to use yaml to describe degenerate object files as well as valid ones, we need to be explicit of some fields in your yaml definitions. llvm-svn: 269313
* [ObjectYAML] Support Thin MachO headers to YAMLChris Bieneman2016-05-122-0/+45
| | | | | | This patch adds support to ObjectYAML for serializing mach_header structs. llvm-svn: 269303
* [lanai] Add Lanai backend.Jacques Pienaar2016-03-281-0/+4
| | | | | | | | | | Add the Lanai backend to lib/Target. General Lanai backend discussion on llvm-dev thread "[RFC] Lanai backend" (http://lists.llvm.org/pipermail/llvm-dev/2016-February/095118.html). Differential Revision: http://reviews.llvm.org/D17011 llvm-svn: 264578

* Move ObjectYAML code to a new library.Rafael Espindola2016-03-014-0/+1397
It is only ever used by obj2yaml and yaml2obj. No point in linking it everywhere. llvm-svn: 262368
