To support this, the RS's API has changed slightly: setScavengingFrameIndex / getScavengingFrameIndex have been replaced by addScavengingFrameIndex / isScavengingFrameIndex / getScavengingFrameIndices.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 2013-03-08T15:36:57Z Tom Stellard thomas.stellard@amd.com 2013-03-08T15:36:57Z urn:sha1:3ef5383b3537a420c5e2ab3e657c378e5185549d 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 2013-03-01T18:40:30Z Michael Liao michael.liao@intel.com 2013-03-01T18:40:30Z urn:sha1:a6b20ced765b67a85d9219d0c8547fc9c133e14f - 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 2013-02-21T20:05:00Z Eli Bendersky eliben@google.com 2013-02-21T20:05:00Z urn:sha1:700ed80d3da5e98e05ceb90e9bfb66058581a6db 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 2013-02-20T21:13:59Z Jim Grosbach grosbach@apple.com 2013-02-20T21:13:59Z urn:sha1:3450f800aa65c91f0496816ba6061a422a74c1fe 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.
