* Replace Count{Leading,Trailing}Zeros_{32,64} with count{Leading,Trailing}Zeros.Michael J. Spencer2013-05-242-3/+3
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182680 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the Copied parameter from MemoryObject::readBytes.Benjamin Kramer2013-05-241-2/+2
| | | | | | | | | | There was exactly one caller using this API right, the others were relying on specific behavior of the default implementation. Since it's too hard to use it right just remove it and standardize on the default behavior. Defines away PR16132. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182636 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't call addFrameMove on XCore.Rafael Espindola2013-05-161-34/+0
| | | | | | | | getExceptionHandlingType is not ExceptionHandling::DwarfCFI on xcore, so etFrameInstructions is never called. There is no point creating cfi instructions if they are never used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181979 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove the MachineMove class.Rafael Espindola2013-05-132-4/+5
| | | | | | | | | | | | It was just a less powerful and more confusing version of MCCFIInstruction. A side effect is that, since MCCFIInstruction uses dwarf register numbers, calls to getDwarfRegNum are pushed out, which should allow further simplifications. I left the MachineModuleInfo::addFrameMove interface unchanged since this patch was already fairly big. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181680 91177308-0d34-0410-b5e6-96231b3b80d8
* Change getFrameMoves to return a const reference.Rafael Espindola2013-05-111-8/+6
| | | | | | | To add a frame now there is a dedicated addFrameMove which also takes care of constructing the move itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181657 91177308-0d34-0410-b5e6-96231b3b80d8

* [XCore] Fix handling of functions where only the LR is spilled.Richard Osborne2013-05-091-27/+30
| | | | | | | | | | | | | | Previously we only checked if the LR required saving if the frame size was non zero. However because the caller reserves 1 word for the callee to use that doesn't count towards our frame size it is possible for the LR to need saving and for the frame size to be 0. We didn't hit when the LR needed saving because of a function calls because the 1 word of stack we must allocate for our callee means the frame size is always non zero in this case. However we can hit this case if the LR is clobbered in inline asm. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181520 91177308-0d34-0410-b5e6-96231b3b80d8

* [XCore] Make use of the target independent global address offset folding.Richard Osborne2013-05-046-98/+41
| | | | | | | | This let us to remove some custom code that matched constant offsets from globals at instruction selection time as a special addressing mode. No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181126 91177308-0d34-0410-b5e6-96231b3b80d8
* [XCore] Simplify code that checks for an aligned base plus a constant.Richard Osborne2013-05-042-81/+56
| | | | | | | | | The code now makes use of ComputeMaskedBits, SelectionDAG::isBaseWithConstantOffset and TargetLowering::isGAPlusOffset where appropriate reducing the amount of logic needed in XCoreISelLowering. No intended functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181125 91177308-0d34-0410-b5e6-96231b3b80d8
* [XCore] Move lowering of thread local storage to a separate pass.Richard Osborne2013-05-046-55/+158
| | | | | | | | | | | | | Thread local storage is not supported by the XMOS linker so we handle thread local variables by lowering the variable to an array of n elements (where n is the number of hardware threads per core, currently 8 for all XMOS devices) indexed by the the current thread ID. Previously this lowering was spread across the XCoreISelLowering and the XCoreAsmPrinter classes. Moving this to a separate pass should be much cleaner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181124 91177308-0d34-0410-b5e6-96231b3b80d8
* [XCore] Use static relocation model by default.Richard Osborne2013-05-044-5/+11
| | | | | | | This allows us to get get rid of a hack in XCoreTargetObjectFile where the the DataRel* sections were overridden. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181116 91177308-0d34-0410-b5e6-96231b3b80d8

* [XCore] The RRegs register class is a superset of GRRegs.Richard Osborne2013-04-044-34/+46
| | | | | | | | | | At the time when the XCore backend was added there were some issues with with overlapping register classes but these all seem to be fixed now. Describing the register classes correctly allow us to get rid of a codegen only instruction (LDAWSP_lru6_RRegs) and it means we can disassemble ru6 instructions that use registers above r11. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178782 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow the register scavenger to spill multiple registersHal Finkel2013-03-221-1/+1
| | | | | | | | | | | | | | | | | | This patch lets the register scavenger make use of multiple spill slots in order to guarantee that it will be able to provide multiple registers simultaneously. To support this, the RS's API has changed slightly: setScavengingFrameIndex / getScavengingFrameIndex have been replaced by addScavengingFrameIndex / isScavengingFrameIndex / getScavengingFrameIndices. In forthcoming commits, the PowerPC backend will use this capability in order to implement the spilling of condition registers, and some special-purpose registers, without relying on r0 being reserved. In some cases, spilling these registers requires two GPRs: one for addressing and one to hold the value being transferred. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177774 91177308-0d34-0410-b5e6-96231b3b80d8
* DAGCombiner: Use correct value type for checking legality of BR_CC v3Tom Stellard2013-03-081-1/+1
| | | | | | | | | | | | | LegalizeDAG.cpp uses the value of the comparison operands when checking the legality of BR_CC, so DAGCombiner should do the same. v2: - Expand more BR_CC value types for NVPTX v3: - Expand correct BR_CC value types for Hexagon, Mips, and XCore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176694 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix PR10475Michael Liao2013-03-011-1/+1
| | | | | | | | | | | | | | | | - ISD::SHL/SRL/SRA must have either both scalar or both vector operands but TLI.getShiftAmountTy() so far only return scalar type. As a result, backend logic assuming that breaks. - Rename the original TLI.getShiftAmountTy() to TLI.getScalarShiftAmountTy() and re-define TLI.getShiftAmountTy() to return target-specificed scalar type or the same vector type as the 1st operand. - Fix most TICG logic assuming TLI.getShiftAmountTy() a simple scalar type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176364 91177308-0d34-0410-b5e6-96231b3b80d8
* Move the eliminateCallFramePseudoInstr method from TargetRegisterInfoEli Bendersky2013-02-214-56/+56
| | | | | | | | | | | | | | | | | to TargetFrameLowering, where it belongs. Incidentally, this allows us to delete some duplicated (and slightly different!) code in TRI. There are potentially other layering problems that can be cleaned up as a result, or in a similar manner. The refactoring was OK'd by Anton Korobeynikov on llvmdev. Note: this touches the target interfaces, so out-of-tree targets may be affected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175788 91177308-0d34-0410-b5e6-96231b3b80d8
* Update TargetLowering ivars for name policy.Jim Grosbach2013-02-201-3/+3
| | | | | | | | | | | http://llvm.org/docs/CodingStandards.html#name-types-functions-variables-and-enumerators-properly ivars should be camel-case and start with an upper-case letter. A few in TargetLowering were starting with a lower-case letter. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175667 91177308-0d34-0410-b5e6-96231b3b80d8
