Fixes pr14751. Patch by Kai; Thanks! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171261 91177308-0d34-0410-b5e6-96231b3b80d8

methods instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171255 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-30Remove the Function::getFnAttributes method in favor of using the AttributeSetBill Wendling
directly. This is in preparation for removing the use of the 'Attribute' class as a collection of attributes. That will shift to the AttributeSet class instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171253 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-27Refactor DAGCombinerInfo. Change the different booleans that indicate if we ↵Nadav Rotem

2012-12-20Use MachineInstrBuilder for PHI nodes in SelectionDAGISel.Jakob Stoklund Olesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170716 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-20Use MachineInstrBuilder in InstrEmitter.Jakob Stoklund Olesen
This is supposed to be a mechanical change with no functional effects. InstrEmitter can generate all types of MachineOperands which revealed that MachineInstrBuilder was missing a few methods, added by this patch. Besides providing a context pointer to MI::addOperand(), MachineInstrBuilder seems like a better fit for this code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170712 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-19After reducing the size of an operation in the DAG we zero-extend the reducedNadav Rotem
bitwidth op back to the original size. If we reduce ANDs then this can cause an endless loop.

2012-12-18Check multiple register classes for inline asm tied registersHal Finkel
A register can be associated with several distinct register classes. For example, on PPC, the floating point registers are each associated with both F4RC (which holds f32) and F8RC (which holds f64). As a result, this code would fail when provided with a floating point register and an f64 operand because it would happen to find the register in the F4RC class first and return that. From the F4RC class, SDAG would extract f32 as the register type and then assert because of the invalid implied conversion between the f64 value and the f32 register. Instead, search all register classes. If a register class containing the the requested register has the requested type, then return that register class. Otherwise, as before, return the first register class found that contains the requested register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170436 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-17Revert/correct some FastISel changes in r170104 (EVT->MVT forPatrik Hagglund
TargetLowering::getRegClassFor). Some isSimple() guards were missing, or getSimpleVT() were hoisted too far, resulting in asserts on valid LLVM assembly input. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170336 91177308-0d34-0410-b5e6-96231b3b80d8

EVT. Accordingly, change RegDefIter to contain MVTs instead of EVTs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170140 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-13Change TargetLowering::getRegClassFor to take an MVT, instead of EVT.Patrik Hagglund
Accordingly, add helper funtions getSimpleValueType (in parallel to getValueType) in SDValue, SDNode, and TargetLowering. This is the first, in a series of patches. This is the second attempt. In the first attempt (r169837), a few getSimpleVT() were hoisted too far, detected by bootstrap failures. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170104 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-12Fix a logic bug in inline expansion of memcpy / memset with an overlappingEvan Cheng
load / store pair. It's not legal to use a wider load than the size of the remaining bytes if it's the first pair of load / store. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170018 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-12Sorry about the churn. One more change to getOptimalMemOpType() hook. Did IEvan Cheng
mention the inline memcpy / memset expansion code is a mess? This patch split the ZeroOrLdSrc argument into two: IsMemset and ZeroMemset. The first indicates whether it is expanding a memset or a memcpy / memmove. The later is whether the memset is a memset of zero. It's totally possible (likely even) that targets may want to do different things for memcpy and memset of zero. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169959 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-12- Rename isLegalMemOpType to isSafeMemOpType. "Legal" is a very overloade term.Evan Cheng
Also added more comments to explain why it is generally ok to return true. - Rename getOptimalMemOpType argument IsZeroVal to ZeroOrLdSrc. It's meant to be true for loaded source (memcpy) or zero constants (memset). The poor name choice is probably some kind of legacy issue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169954 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-12Avoid using lossy load / stores for memcpy / memset expansion. e.g.Evan Cheng
f64 load / store on non-SSE2 x86 targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169944 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-11Replace TargetLowering::isIntImmLegal() withEvan Cheng
ScalarTargetTransformInfo::getIntImmCost() instead. "Legal" is a poorly defined term for something like integer immediate materialization. It is always possible to materialize an integer immediate. Whether to use it for memcpy expansion is more a "cost" conceern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169929 91177308-0d34-0410-b5e6-96231b3b80d8
