2008-08-28Add support for JIT exceptions on Darwin. Since we're dealing with libgcc,Nicolas Geoffray
whose darwin code was written after the ability to dynamically register frames, we need to do special hacks to make things work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55507 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-28Optimize DAGCombiner's worklist processing. Previously it startedDan Gohman
its work by putting all nodes in the worklist, requiring a big dynamic allocation. Now, DAGCombiner just iterates over the AllNodes list and maintains a worklist for nodes that are newly created or need to be revisited. This allows the worklist to stay small in most cases, so it can be a SmallVector. This has the side effect of making DAGCombine not miss a folding opportunity in alloca-align-rounding.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55498 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Move CaseBlock, JumpTable, and BitTestBlock to be members ofDan Gohman
SelectionDAGLowering instead of being in an anonymous namespace. This fixes warnings about SelectionDAGLowering having fields using anonymous namespaces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55497 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Fix a FastISel bug where the instructions from lowering the argumentsDan Gohman
were being emitted after the first instructions of the entry block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55496 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55486 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-28Hook up support for fast-isel of trunc instructions, using the newly working ↵Owen Anderson
support for EXTRACT_SUBREG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55482 91177308-0d34-0410-b5e6-96231b3b80d8

Re-materialize the src to replace the copy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55467 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28FsFLD0S{S|D} and V_SETALLONES are as cheap as moves.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55466 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Make the verifier reject instructions which have null pointers Chris Lattner
for operands: rdar://6179606. no testcase, because I can't write a .ll file that is this broken ;-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55460 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Clear the intervals list in "destroy", patch by Chris Lattner
Prakash Prabhu! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55458 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-28Split the ATOMIC NodeType's to include the size, e.g.Dale Johannesen
ATOMIC_LOAD_ADD_{8,16,32,64} instead of ATOMIC_LOAD_ADD. Increased the Hardcoded Constant OpActionsCapacity to match. Large but boring; no functional change. This is to support partial-word atomics on ppc; i8 is not a valid type there, so by the time we get to lowering, the ATOMIC_LOAD nodes looks the same whether the type was i8 or i32. The information can be added to the AtomicSDNode, but that is the largest SDNode; I don't fully understand the SDNode allocation, but it is sensitive to the largest node size, so increasing that must be bad. This is the alternative. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55457 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-27Reorganize the lifetimes of the major objects SelectionDAGISelDan Gohman
works with. SelectionDAG, FunctionLoweringInfo, and SelectionDAGLowering objects now get created once per SelectionDAGISel instance, and can be reused across blocks and across functions. Previously, they were created and destroyed each time they were needed. This reorganization simplifies the handling of PHI nodes, and also SwitchCases, JumpTables, and BitTestBlocks. This simplification has the side effect of fixing a bug in FastISel where successor PHI nodes weren't being updated correctly. This is also a step towards making the transition from FastISel into and out of SelectionDAG faster, and also making plain SelectionDAG faster on code with lots of little blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55450 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-27Add a helper method that will be used to support EXTRACT_SUBREG for ↵Owen Anderson
selecting trunc's in fast-isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55439 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-27Make "movdq2q" and "movq2dq" dependent upon having SSE2 because they use theBill Wendling
SSE2 registers as well as the MMX registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55436 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-27Put file scoped constants in an anonymous namespace. Use the "using namespaceBill Wendling
llvm" for consistency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55435 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-27Use TargetLowering to get the types in fast isel, which handles pointer ↵Owen Anderson
types correctly for our purposes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55428 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-27Don't check TLI.getOperationAction. The FastISel way is toDan Gohman
just try to do the action and let the tablegen-generated code determine if there is target-support for an operation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55427 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-27Reinstate the x86-64 portion of r55190. When doing extloads intoDan Gohman
64-bit registers from 16-bit and smaller memory locations, prefer instructions that define the entire 64-bit register, to avoid partial-register updates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@55422 91177308-0d34-0410-b5e6-96231b3b80d8
