2008-10-31Add a bunch of libcalls for ppcf128 that were somehowDuncan Sands
completely forgotten about when writing LegalizeTypes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58508 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-31Don't skip over all "terminator" instructions when determining where to put theBill Wendling
callee-saved restore code. It could skip over conditional jumps accidentally. Instead, just skip the "return" instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58489 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-30Fix PR2986: do not use a potentially illegalDuncan Sands
type for the shift amount type. Add a check that shifts and rotates use the type returned by getShiftAmountTy for the amount. This exposed some problems in CellSPU and PPC, which have already been fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58455 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-29Add sanity checking for BUILD_PAIR (I noticed theDuncan Sands
other day that PPC custom lowering could create a BUILD_PAIR of two f64 with a result type of... f64! - already fixed). Fix a place that triggers the sanity check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58378 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-29- More pre-split fixes: spill slot live interval computation bug; restore ↵Evan Cheng
point bug. - If a def is spilt, remember its spill index to allow its reuse. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58375 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-29Fix a FIXME: in ReplaceNodeWith, if the new nodeDuncan Sands
is morphed by AnalyzeNewNode into a previously processed node, and different result values of that node are remapped to values with different nodes, then we could end up using wrong values here [we were assuming that all results remap to values with the same underlying node]. This seems theoretically possible, but I don't have a testcase. The meat of the patch is in the changes to AnalyzeNewNode/AnalyzeNewValue and ReplaceNodeWith. While there, I changed names like RemapNode to RemapValue, since it really remaps values. To tell the truth, I would be much happier if we were only remapping nodes (it would simplify a bunch of logic, and allow for some cute speedups) but I haven't yet worked out how to do that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58372 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-29- Rewrite code that update register live interval that's split.Evan Cheng
- Create and update spill slot live intervals. - Lots of bug fixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58367 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-28Take Chris' suggestion and define EnableFastISelVerbose andDan Gohman

2008-10-28Fix darwin ppc llvm-gcc build breakage: interceptDuncan Sands
ppcf128 to i32 conversion and expand it into a code sequence like in LegalizeDAG. This needs custom ppc lowering of FP_ROUND_INREG, so turn that on and make it work with LegalizeTypes. Probably PPC should simply custom lower the original conversion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58329 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-28Fix a testcase provided by Bill in which the nodeDuncan Sands
id could end up being wrong mostly because of forgetting to remap new nodes that morphed into processed nodes through CSE. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58323 91177308-0d34-0410-b5e6-96231b3b80d8

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
2008-10-27Turn on LegalizeTypes, the new type legalizationDuncan Sands
codegen infrastructure, by default. Please report any breakage to the mailing lists. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58232 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

2008-10-25SDNodes may have at most one Flag result. Update this commentDan Gohman
to reflect that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58145 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
2008-10-25If val# def is ~0U, meaning it's defined by a PHI, and it's previously ↵Evan Cheng
split, spill before the barrier because it's impossible to determine if all the defs are spilled in the same spill slot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58129 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-23Committing a good chunk of the pre-register allocation live interval ↵Evan Cheng
splitting pass. It's handling simple cases and appear to do good things. Next: avoid splitting an interval multiple times; renumber registers when possible; record stack slot live intervals for coloring; rematerialize defs when possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58044 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-22Be nice to CellSPU: for this target getSetCCResultTypeDuncan Sands
may return i8, which can result in SELECT nodes for which the type of the condition is i8, but there are no patterns for select with i8 condition. Tweak the LegalizeTypes logic to avoid this as much as possible. This isn't a real fix because it is still perfectly possible to end up with such select nodes - CellSPU needs to be fixed IMHO. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57968 91177308-0d34-0410-b5e6-96231b3b80d8
