* Fix pr19645.Rafael Espindola2014-05-03
| | | | | | | | | | | | | | | | The fix itself is fairly simple: move getAccessVariant to MCValue so that we replace the old weak expression evaluation with the far more general EvaluateAsRelocatable. This then requires that EvaluateAsRelocatable stop when it finds a non trivial reference kind. And that in turn requires the ELF writer to look harder for weak references. Last but not least, this found a case where we were being bug by bug compatible with gas and accepting an invalid input. I reported pr19647 to track it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207920 91177308-0d34-0410-b5e6-96231b3b80d8

* MC: add a RefKind field to MCValueTim Northover2014-03-29
| | | | | | | | This is principally to allow neater mapping of fixups to relocations in ARM64 ELF. Without this, there isn't enough information available to GetRelocType, leading to many more fixup_arm64_... enumerators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205085 91177308-0d34-0410-b5e6-96231b3b80d8
