2011-06-19When promoting the vector elements in CopyToParts, use vector truncNadav Rotem
instead of scalarizing, and doing an element-by-element truncat. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133382 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-16Introduce MachineBranchProbabilityInfo class, which has similar API toJakub Staszak
BranchProbabilityInfo (expect setEdgeWeight which is not available here). Branch Weights are kept in MachineBasicBlocks. To turn off this analysis set -use-mbpi=false. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133184 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-16Add TargetRegisterInfo::getRawAllocationOrder().Jakob Stoklund Olesen
This virtual function will replace allocation_order_begin/end as the one to override when implementing custom allocation orders. It is simpler to have one function return an ArrayRef than having two virtual functions computing different ends of the same array. Use getRawAllocationOrder() in place of allocation_order_begin() where it makes sense, but leave some clients that look like they really want the filtered allocation orders from RegisterClassInfo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133170 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-12Improve the generated code by getCopyFromPartsVector for promoted integer types.Nadav Rotem
Instead of scalarizing, and doing an element-by-element truncat, use vector truncate. Add support for scalarization of vectors: i8 -> <1 x i1> (from Duncan's testcase). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132892 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-11Give the 'eh.sjlj.dispatchsetup' intrinsic call the value coming from the setjmpBill Wendling
intrinsic call. This prevents it from being reordered so that it appears *before* the setjmp intrinsic (thus making it completely useless). <rdar://problem/9409683> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131174 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-05Revamp the SjLj "dispatch setup" intrinsic.Bill Wendling
It needed to be moved closer to the setjmp statement, because the code directly after the setjmp needs to know about values that are on the stack. Also, the 'bitcast' of the function context was causing a dead load. This wouldn't be too horrible, except that at -O0 it wasn't optimized out, and because it wasn't using the correct base pointer (if there is a VLA), it would try to access a value from a garbage address. <rdar://problem/9130540> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128873 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-26Turn SelectionDAGBuilder::GetRegistersForValue into a local function.Benjamin Kramer
It couldn't be used outside of the file because SDISelAsmOperandInfo is local to SelectionDAGBuilder.cpp. Making it a static function avoids a weird linkage dance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128342 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-16The x86-64 ABI says that a bool is only guaranteed to be sign-extended to a byteCameron Zwarich
rather than an int. Thankfully, this only causes LLVM to miss optimizations, not generate incorrect code. This just fixes the zext at the return. We still insert an i32 ZextAssert when reading a function's arguments, but it is followed by a truncate and another i8 ZextAssert so it is not optimized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127766 91177308-0d34-0410-b5e6-96231b3b80d8
