2008-10-27Add STL-style typedefs and default constructors to make it possible toDavid Greene

2008-10-27Fix PR2634. Create new virtual registers from spills early so that weDavid Greene
can give it the same stack slot as the spilled interval if it is folded. This prevents the fold/unfold code from pointing to the wrong register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58255 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-27Fix UpdateNodeOperands so that it does CSE of callsDuncan Sands
(and a bunch of other node types). While there, I added a doNotCSE predicate and used it to reduce code duplication (some of the duplicated code was wrong...). This fixes ARM/cse-libcalls.ll when using LegalizeTypes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58249 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-27Fix a bug in which a node could be added to theDuncan Sands
worklist twice: UpdateNodeOperands could morph a new node into a node already on the worklist. We would then recalculate the NodeId for this existing node and add it to the worklist. The testcase is ARM/cse-libcalls.ll, the problem showing up once UpdateNodeOperands is taught to do CSE for calls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58246 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-27For now, don't split live intervals around x87 stack register barriers. ↵Evan Cheng
FpGET_ST0_80 must be right after a call instruction (and ADJCALLSTACKUP) so we need to find a way to prevent reload of x87 registers between them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58230 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-27Rewrite all the 'PromoteLocallyUsedAlloca[s]' logic. With the power ofChris Lattner
LargeBlockInfo, we can now dramatically simplify their implementation and speed them up at the same time. Now the code has time proportional to the number of uses of the alloca, not the size of the block. This also eliminates code that tried to batch up different allocas which are used in the same blocks, and eliminates the 'retry list' logic which was baroque and no unneccesary. In addition to being a speedup for crazy cases, this is also a nice cleanup: PromoteMemoryToRegister.cpp | 270 +++++++++++++++----------------------------- 1 file changed, 96 insertions(+), 174 deletions(-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58229 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-27Add a new LargeBlockInfo helper, which is just a wrapper aroundChris Lattner
a trivial dense map. Use this in RewriteSingleStoreAlloca to avoid aggressively rescanning blocks over and over again. This fixes PR2925, speeding up mem2reg on the testcase in that bug from 4.56s to 0.02s in a debug build on my machine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58227 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-25Move the code that adds the DeadMachineInstructionElimPass fromDan Gohman
target-independent code to target-specific code. This prevents it from running on targets that aren't using fast-isel. In addition to saving compile time, this addresses the problem that not all targets are prepared for it. In order to use this pass, all instructions must declare all their fixed uses and defs of physical registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58144 91177308-0d34-0410-b5e6-96231b3b80d8
