2010-08-24Fix COFF x86-64 relocations. PR7960.Michael J. Spencer
Multiple symbol reloc handling part of the patch by Cameron Esfahani. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111963 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-24First bit of support for the dwarf .loc directive. This patch updates theKevin Enderby
needed parsing for the .loc directive and saves the current info from that into the context. The next patch will take the current loc info after an instruction is assembled and save that info into a vector for each section for use to build the line number tables. The patch after that will encode the info from those vectors into the output file as the dwarf line tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111956 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-24MC/Parser: Accept leading dollar signs in identifiers.Daniel Dunbar
- Implemented by manually splicing the tokens. If this turns out to be problematically platform specific, a more elegant solution would be to implement some context dependent lexing support. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111934 91177308-0d34-0410-b5e6-96231b3b80d8
