* Added MispredictPenalty to SchedMachineModel.Andrew Trick2012-08-084-9/+9
| | | | | | | This replaces an existing subtarget hook on ARM and allows standard CodeGen passes to potentially use the property. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161471 91177308-0d34-0410-b5e6-96231b3b80d8

* X86: enable CSE between CMP and SUBManman Ren2012-08-084-47/+98
| | | | | | | | | | | | | | | We perform the following: 1> Use SUB instead of CMP for i8,i16,i32 and i64 in ISel lowering. 2> Modify MachineCSE to correctly handle implicit defs. 3> Convert SUB back to CMP if possible at peephole. Removed pattern matching of (a>b) ? (a-b):0 and like, since they are handled by peephole now. rdar://11873276 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161462 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't scan physreg use-def chains looking for a PIC base.Jakob Stoklund Olesen2012-08-081-10/+4
| | | | | | | | | | We can't rematerialize a PIC base after register allocation anyway, and scanning physreg use-def chains is very expensive in a function with many calls. <rdar://problem/12047515> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161461 91177308-0d34-0410-b5e6-96231b3b80d8

* Allow x86 subtargets to use the GenericModel defined in X86Schedule.td.Andrew Trick2012-08-071-3/+3
| | | | | | | | | | | This allows codegen passes to query properties like InstrItins->SchedModel->IssueWidth. It also ensure's that computeOperandLatency returns the X86 defaults for loads and "high latency ops". This should have no significant impact on existing schedulers because X86 defaults happen to be the same as global defaults. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161370 91177308-0d34-0410-b5e6-96231b3b80d8

* The Mips64InstrInfo.td definitions DynAlloc64 LEA_ADDiu64 Jack Carter2012-08-062-14/+10
| | | | | | | | | | | were using a class defined for 32 bit instructions and thus the instruction was for addiu instead of daddiu. This was corrected by adding the instruction opcode as a field in the base class to be filled in by the defs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161359 91177308-0d34-0410-b5e6-96231b3b80d8

* MFTB on PPC64 should really be encoded using MFSPR.Hal Finkel2012-08-061-2/+2
| | | | | | | | | | | The MFTB instruction itself is being phased out, and its functionality is provided by MFSPR. According to the ISA docs, using MFSPR works on all known chips except for the 601 (which did not have a timebase register anyway) and the POWER3.

* Fall back to selection DAG isel for calls to builtin functions.Bob Wilson2012-08-036-15/+26
| | | | | | | | | | Fast isel doesn't currently have support for translating builtin function calls to target instructions. For embedded environments where the library functions are not available, this is a matter of correctness and not just optimization.
