* [yaml2obj][ELF] Don't monkeypatch the YAML sections.Sean Silva2013-06-18
| | | | | | | | | | | | | Previously, we would monkeypatch the vector of YAML::Section's in order to ensure that the SHT_NULL entry is present. Now we just add it unconditionally. The proliferation of small numerical adjustments is beginning to frighten me, but I can't think of a way having a single point of truth for them without introducing a whole new layer of data structures (i.e. lots of code and complexity) between the YAML and binary ELF formats. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184260 91177308-0d34-0410-b5e6-96231b3b80d8

* [yaml2obj][ELF] Rudimentary symbol table support.Sean Silva2013-06-18
| | | | | | Currently, we only output the name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184255 91177308-0d34-0410-b5e6-96231b3b80d8
* [yaml2obj][ELF] Add dummy .strtab section.Sean Silva2013-06-18
| | | | | | | This will be needed later for holding symbol names, due to the libObject issue mentioned in the commit message of r184161. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184242 91177308-0d34-0410-b5e6-96231b3b80d8
* [yaml2obj][ELF] Factor out string table section creation.Sean Silva2013-06-18
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184162 91177308-0d34-0410-b5e6-96231b3b80d8
* [yaml2obj][ELF] Refer specifically to the section header string table.Sean Silva2013-06-18
| | | | | | | | | | | | | | | A bug in libObject will cause it to assert() if a symbol table's string table and the section header string table are the same section, so we need to ensure that we emit two different string tables (among other things). The problematic code is the hardcoded usage of ".strtab" (`dot_strtab_sec`) for looking up symbol names in ELFObjectFile<ELFT>::getSymbolName. I discussed this with Michael, and he has some local improvements to the ELF code in libObject that, among other things, should fix our handling of this scenario. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184161 91177308-0d34-0410-b5e6-96231b3b80d8
* [yaml2obj][ELF] Ensure more fields are zero'd.Sean Silva2013-06-18
| | | | | | | | | | | | I was spotting garbage in the output. I'd like to just zero the entire ELFYAML::Section to be sure, but it contains non-POD types. (I'm also trying to avoid bloating the ELFYAML::Foo classes with a bunch of constructor code). No test, since this is by its very nature unpredictable. I'm pretty sure that one of the sanitizers would catch it immediately though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184160 91177308-0d34-0410-b5e6-96231b3b80d8

* [yaml2obj] Add support for sh_addralign via `AddressAlign` key.Sean Silva2013-06-14
| | | | | | | For consistency, change the address in the test case from 0xDEADBEEF to 0xCAFEBABE since 0xCAFEBABE that actually has a 2-byte alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183962 91177308-0d34-0410-b5e6-96231b3b80d8

* [yaml2obj] Initial ELF section support.Sean Silva2013-06-13
| | | | | | | The current functionality is extremely basic and a bit rough around the edges, but it will flesh out in future commits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183953 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix dubious type name similar to member name.Sean Silva2013-06-11
| | | | | | Should bring bots back to life. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183715 91177308-0d34-0410-b5e6-96231b3b80d8
* [yaml2obj] Initial ELF support.Sean Silva2013-06-10
| | | | | | | | | Currently, only emitting the ELF header is supported (no sections or segments). The ELFYAML code organization is broadly similar to the COFFYAML code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183711 91177308-0d34-0410-b5e6-96231b3b80d8

* Add BinaryRef binary_size() method.Sean Silva2013-06-05
| | | | | | This avoids making assumptions about the data representation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183349 91177308-0d34-0410-b5e6-96231b3b80d8
* Add writeAsBinary(raw_ostream &) method to BinaryRef.Sean Silva2013-06-05
| | | | | | | | | | | Previously, yaml2coff.cpp had a writeHexData static helper function to do this, but it is generally useful functionality. Also, validate hex strings up-front to avoid running having to handle errors "deep inside" the yaml2obj code (it also gives better diagnostics than it used to). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183345 91177308-0d34-0410-b5e6-96231b3b80d8
* yaml2obj: split out COFF logic into separate fileSean Silva2013-06-05

* yaml2obj: add -format=<fmt> to choose input YAML interpretationSean Silva2013-06-05
| | | | | | | | | | | | See the comment in yaml2obj.cpp for why this is currently needed. Eventually we can get rid of this, but for now it is needed in order to make forward progress with adding ELF support, and should be straightforward to remove later. Also, preserve the default of COFF, to avoid breaking existing tests. This policy can easily be changed later though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183332 91177308-0d34-0410-b5e6-96231b3b80d8

* Split Alignment out of the Section Characteristics.Rafael Espindola2013-05-06
| | | | | | | | The alignment is just a byte in the middle of Characteristics, not an independent flag. Making it an independent field in the yaml representation makes it more yamlio friendly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181243 91177308-0d34-0410-b5e6-96231b3b80d8

* Simplify yaml2obj a bit.Rafael Espindola2013-04-23
| | | | | | | | | | | | The COFFParser now contains only a COFFYAML::Object and the string table (which is recomputed, not serialized). The structs in COFFParser now all begin with a Header field with what is actually on the COFF object. The other fields are things that are semantically part of the struct (relocations in a section for exmaple), but are not actually represented that way in the object file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180134 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove COFFYAML::Header.Rafael Espindola2013-04-20
| | | | | | | Instead, use MappingNormalization to directly parse COFF::header. Also change the naming convention of the helper classes to be a bit shorter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179917 91177308-0d34-0410-b5e6-96231b3b80d8
