2012-11-24Give each MCCFIInstruction its own opcode.Rafael Espindola
This untangles the switch cases of the old Move and RelMove opcodes a bit and makes it clear how to add new instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168534 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-24Refactor how MCCFIInstructions are created.Rafael Espindola
Give MCCFIInstruction a single, private constructor and add helper static methods that create each type of cfi instruction. This is is preparation for changing its representation. The representation with a pair MachineLocations older than MC and has been abused quiet a bit to support more cfi instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168532 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-25Initial TOC support for PowerPC64 object creationAdhemerval Zanella
This patch adds initial PPC64 TOC MC object creation using the small mcmodel (a single 64K TOC) adding the some TOC relocations (R_PPC64_TOC, R_PPC64_TOC16, and R_PPC64_TOC16DS). The addition of 'undefinedExplicitRelSym' hook on 'MCELFObjectTargetWriter' is meant to avoid the creation of an unreferenced ".TOC." symbol (used in the .odp creation) as well to set the R_PPC64_TOC relocation target as the temporary ".TOC." symbol. On PPC64 ABI, the R_PPC64_TOC relocation should not point to any symbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166677 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-24[ms-inline asm] Create a register operand, rather than a memory operand when weChad Rosier
see the offsetof operator. Previously, we were matching something like MOVrm in the front-end and later matching MOVrr in the back-end. This change makes things more consistent. It also fixes cases where we can't match against a memory operand as the source (test cases coming).

2012-10-22Add support for annotated disassembly output for X86 and arm.Kevin Enderby
Per the October 12, 2012 Proposal for annotated disassembly output sent out by Jim Grosbach this set of changes implements this for X86 and arm. The llvm-mc tool now has a -mdis option to produced the marked up disassembly and a couple of small example test cases have been added. rdar://11764962 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166445 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-18[ms-inline asm] Have the LookupInlineAsmIdentifier() callback function return aChad Rosier

2012-10-18[ms-inline asm] Move most of the AsmParsing logic in clang back into the MCChad Rosier
layer. Add the ParseMSInlineAsm() function, which is the new interface to clang. Also expose the new MCAsmParserSemaCallback interface, which is used by the back-end to do name lookup in Sema. Finally, remove the now defunct APIs introduced in r165946. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166183 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-15[ms-inline asm] Add a few new APIs to the AsmParser class in support of MS-StyleChad Rosier
inline assembly. For the time being, these will be called directly by clang. However, in the near future I expect these to be sunk back into the MC layer and more basic APIs (e.g., getClobbers(), getConstraints(), etc.) will be called by clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165946 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-15PowerPC: add EmitTCEntry class for TOC creationAdhemerval Zanella

2012-10-13[ms-inline asm] Remove the MatchInstruction() function. Previously, this wasChad Rosier
the interface between the front-end and the MC layer when parsing inline assembly. Unfortunately, this is too deep into the parsing stack. Specifically, we're unable to handle target-independent assembly (i.e., assembly directives, labels, etc.). Note the MatchAndEmitInstruction() isn't the correct abstraction either. I'll be exposing target-independent hooks shortly, so this is really just a cleanup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165858 91177308-0d34-0410-b5e6-96231b3b80d8
