* Merging MIPS GOT changeset into 3.2 release branch.Pawel Wodnicki2012-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merging r168471: Mips direct object xgot support This patch provides support for the MIPS relocations: *) R_MIPS_GOT_HI16 *) R_MIPS_GOT_LO16 *) R_MIPS_CALL_HI16 *) R_MIPS_CALL_LO16 These are used for large GOT instruction sequences. Contributer: Jack Carter Merging r168460: [mips] Generate big GOT code. Merging r168458: [mips] Simplify lowering functions in MipsISelLowering.cpp by using the helper functions added in r168456. Merging r168456: [mips] Add helper functions that create nodes for computing address. Merging r168455: [mips] Add command line option "-mxgot". Merging r168453: [mips] When a node which loads from a GOT is created, pass a MachinePointerInfo referring to a GOT entry. Merging r168450: [mips] Add target operand flag enums for big GOT relocations. Merging r168448: Add relocations used for mips big GOT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@169294 91177308-0d34-0410-b5e6-96231b3b80d8

* Initial TOC support for PowerPC64 object creationAdhemerval Zanella2012-10-25
| | | | | | | | | | | | | | | | 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
* [ms-inline asm] Create a register operand, rather than a memory operand when weChad Rosier2012-10-24
| | | | | | | | | | | | 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).

| | | | | | | | | | | | 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 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
