* Remove PPC ELF targetGreg Fitzgerald2015-01-281-29/+0

* Fix the ELF shared library build targets - take 2Greg Fitzgerald2015-01-241-0/+13
| | | | | | | | | | lldELF is used by each ELF backend. lldELF's ELFLinkingContext also held a reference to each backend, creating a link-time cycle. This patch moves the backend references to lldDriver. Differential Revision: http://reviews.llvm.org/D7119 llvm-svn: 226976

* [ELF] Add Readers for all the ELF subtargets.Shankar Easwaran2014-10-181-2/+0
| | | | | | | | | This would permit the ELF reader to check the architecture that is being selected by the linking process. This patch also sorts the include files according to LLVM conventions. llvm-svn: 220129
* [lld] Introduce registry and Reference kind tupleNick Kledzik2013-12-191-28/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main changes are in: include/lld/Core/Reference.h include/lld/ReaderWriter/Reader.h Everything else is details to support the main change. 1) Registration based Readers Previously, lld had a tangled interdependency with all the Readers. It would have been impossible to make a streamlined linker (say for a JIT) which just supported one file format and one architecture (no yaml, no archives, etc). The old model also required a LinkingContext to read an object file, which would have made .o inspection tools awkward. The new model is that there is a global Registry object. You programmatically register the Readers you want with the registry object. Whenever you need to read/parse a file, you ask the registry to do it, and the registry tries each registered reader. For ease of use with the existing lld code base, there is one Registry object inside the LinkingContext object. 2) Changing kind value to be a tuple Beside Readers, the registry also keeps track of the mapping for Reference Kind values to and from strings. Along with that, this patch also fixes an ambiguity with the previous Reference::Kind values. The problem was that we wanted to reuse existing relocation type values as Reference::Kind values. But then how can the YAML write know how to convert a value to a string? The fix is to change the 32-bit Reference::Kind into a tuple with an 8-bit namespace (e.g. ELF, COFFF, etc), an 8-bit architecture (e.g. x86_64, PowerPC, etc), and a 16-bit value. This tuple system allows conversion to and from strings with no ambiguities. llvm-svn: 197727
* [PassManager] add ReaderWriter{Native,YAML} to the Driver.Shankar Easwaran2013-10-291-1/+2
| | | | | | | | | | | | | Enable this for the following flavors a) core b) gnu c) darwin Its disabled for the flavor PECOFF. Convenient markers are added with FIXME comments in the Driver that would be removed and code removed from each flavor. llvm-svn: 193585
* Put missing license header.Rui Ueyama2013-10-251-0/+9

* Update error classes from all lowercase to camel case.Rui Ueyama2013-10-091-2/+2

* Rename TargetInfo -> LinkingContext.Rui Ueyama2013-08-061-0/+36
Also change some local variable names: "ti" -> "context" and "_targetInfo" -> "_context". Differential Revision: http://llvm-reviews.chandlerc.com/D1301 llvm-svn: 187823
