2012-08-13Remove the LowerMMXCONCAT_VECTORS function. It could never execute because ↵Craig Topper

2012-08-09[ms-inline asm] Extend the MC AsmParser API to match MCInsts (but not emit).Chad Rosier
This new API will be used by clang to parse ms-style inline asms. One goal of this project is to use this style of inline asm for targets other then x86. Therefore, this API needs to be implemented for non-x86 targets at some point in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161624 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-08Don't use getNextOperandForReg().Jakob Stoklund Olesen
This way of using getNextOperandForReg() was unlikely to work as intended. We don't give any guarantees about the order of operands in the use-def chains, so looking only at operands following a given operand in the chain doesn't make sense. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161542 91177308-0d34-0410-b5e6-96231b3b80d8

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) ?

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

2012-08-07Allow x86 subtargets to use the GenericModel defined in X86Schedule.td.Andrew Trick
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

2012-08-06The Mips64InstrInfo.td definitions DynAlloc64 LEA_ADDiu64 Jack Carter
were using a class defined for 32 bit instructions and thus the instruction was for addiu instead of daddiu.

2012-08-06MFTB on PPC64 should really be encoded using MFSPR.Hal Finkel
The MFTB instruction itself is being phased out, and its functionality is provided by MFSPR.
