* misched: TargetSchedule interface for machine resources.Andrew Trick2012-11-06
| | | | | | | | | | | Expose the processor resources defined by the machine model to the scheduler and other clients through the TargetSchedule interface. Normalize each resource count with respect to other kinds of resources. This allows scheduling heuristics to balance resources against other kinds of resources and latency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167444 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

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

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

* [ms-inline asm] Add basic support for wildcard MCParsedAsmOperands. This typeChad Rosier2012-10-02
| | | | | | | | | | | | | | of operand is specific to MS-style inline assembly and should not be generated when parsing normal assembly. The purpose of the wildcard operands are to allow the AsmParser to match multiple instructions (i.e., MCInsts) to a given ms-style asm statement. For the time being the matcher just returns the first match. This patch only implements wildcard matches for memory operands. Support for register wildcards will be added in the near future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165057 91177308-0d34-0410-b5e6-96231b3b80d8
