2006-08-08Start eliminating temporary vectors used to create DAG nodes. Instead, passChris Lattner
in the start of an array and a count of operands where applicable. In many cases, the number of operands is known, so this static array can be allocated on the stack, avoiding the heap. In many other cases, a SmallVector can be used, which has the same benefit in the common cases. I updated a lot of code calling getNode that takes a vector, but ran out of time. The rest of the code should be updated, and these methods should be removed. We should also do the same thing to eliminate the methods that take a vector of MVT::ValueTypes. It would be extra nice to convert the dagiselemitter to avoid creating vectors for operands when calling getTargetNode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29566 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-03Refactor TargetMachine, pushing handling of TargetData into the ↵Owen Anderson
target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference. This fixes PR 759. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28074 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-22JumpTable support! What this represents is working asm and jit support forNate Begeman
x86 and ppc for 100% dense switch statements when relocations are non-PIC. This support will be extended and enhanced in the coming days to support PIC, and less dense forms of jump tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27947 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-27Translate llvm target registers to dwarf register numbers properly.Jim Laskey
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27180 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-27SelectionDAGISel can now natively handle Switch instructions, in the sameNate Begeman
manner that the LowerSwitch LLVM to LLVM pass does: emitting a binary search tree of basic blocks. The new approach has several advantages: it is faster, it generates significantly smaller code in many cases, and it paves the way for implementing dense switch tables as a jump table by handling switches directly in the instruction selector. This functionality is currently only enabled on x86, but should be safe for every target. In anticipation of making it the default, the cfg is now properly updated in the x86, ppc, and sparc select lowering code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27156 91177308-0d34-0410-b5e6-96231b3b80d8
