* [DWARF] - Make collectAddressRanges() return section index in addition to ↵George Rimar2017-05-261-0/+4
| | | | | | | | | | | | | | | | | | | | | | Low/High PC This change is intended to use for LLD in D33183. Problem we have in LLD when building .gdb_index is that we need to know section which address range belongs to. Previously it was solved on LLD side by providing fake section addresses with use of llvm::LoadedObjectInfo interface. We assigned file offsets as addressed. Then after obtaining ranges lists, for each range we had to find section ID's. That not only was slow, but also complicated implementation and was the reason of incorrect behavior when sections share the same offsets, like D33176 shows. This patch makes DWARF parsers to return section index as well. That solves problem mentioned above. Differential revision: https://reviews.llvm.org/D33184 llvm-svn: 303978
* [WebAssembly] Improve libObject support for wasm imports and exportsSam Clegg2017-05-091-10/+29
| | | | | | | | | | | | Previously we had only supported the importing and exporting of functions and globals. Also, add usefull overload of getWasmSymbol() and getNumberOfSymbols() in support of lld port. Differential Revision: https://reviews.llvm.org/D33011 llvm-svn: 302601
* [WebAssembly] Fix validation of start functionSam Clegg2017-05-091-1/+1
| | | | | | | | | | The check for valid start function was inverted. Added a new test in test/Object to check this case and fixed the existing tests in for ObjectYAML. Differential Revision: https://reviews.llvm.org/D32986 llvm-svn: 302560

* [WebAssembly] Allow for signed relocation addendsSam Clegg2017-04-261-2/+3
| | | | | | | | | | | | | | Summary: Addends are used as offsets to addresses of globals and can be both positive and negative. This change prints libObject in line with the spec and the MC layer. Subscribers: jfb, dschuff Differential Revision: https://reviews.llvm.org/D32507 llvm-svn: 301369

* [WebAssembly] Improve support for WebAssembly binary formatDerek Schuff2017-03-301-61/+574
| | | | | | | | | | | | | | | | | | | Mostly this change adds support converting to and from YAML which will allow us to write more test cases for the WebAssembly MC and lld ports. Better support for objdump, readelf, and nm will be in followup CLs. I had to update the two wasm test binaries because they used the old style 'name' section which is no longer supported.
