2008-07-05Fixed generating incorrect aligned stores that I backout of r53031Mon P Wang
that fixed problems in EmitStackConvert where the source and target type have different alignment by creating a stack slot with the max alignment of source and target type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53150 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-04Rather than having a different custom legalizationDuncan Sands
hook for each way in which a result type can be legalized (promotion, expansion, softening etc), just use one: ReplaceNodeResults, which returns a node with exactly the same result types as the node passed to it, but presumably with a bunch of custom code behind the scenes. No change if the new LegalizeTypes infrastructure is not turned on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53137 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-04Linux also does not require exception handlingDuncan Sands
moves in order to get correct debug info. Since I can't imagine how any target could possibly be any different, I've just stripped out the option: now all the world's like Darwin! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53134 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-03Don't return std::vector by value, but pass it in by reference to be filled.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53123 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-03Revert my previous check-in that split up MachineModuleInfo. It turns out toBill Wendling
slow the compiler down at -O0 some 30% or more. Ooops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53120 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-03Backed out 53031.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53110 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-03- Remove calls to copyKillDeadInfo which is an N^2 function. Instead, ↵Evan Cheng
propagate kill / dead markers as new instructions are constructed in foldMemoryOperand, convertToThressAddress, etc. - Also remove LiveVariables::instructionChanged, etc. Replace all calls with cheaper calls which update VarInfo kill list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53097 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-03Reapply r52988, "Simplify addRegisterKilled and addRegisterDead." TheDan Gohman
254.gap failure was not due to this mod. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53068 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-03Avoid unnecessarily copying APInt objects.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53065 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-03Use std::replace instead of std::find and push_back.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53063 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-03- Add LiveVariables::replaceKillInstruction. This does a subset of ↵Evan Cheng
instructionChanged. That is, it only update the VarInfo.kills if the new instruction is known to have the correct dead and kill markers. - CommuteInstruction copies kill / dead markers over to new instruction. So use replaceKillInstruction instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53061 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-02Make LiveVariables even more optional, by making it optional in the call to ↵Owen Anderson
TargetInstrInfo::convertToThreeAddressInstruction Also, if LV isn't around, then TwoAddr doesn't need to be updating flags, since they won't have been set in the first place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53058 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-02Replace a few uses of SelectionDAG::getTargetNode withDan Gohman
SelectionDAG::SelectNodeTo in the instruction selector. This updates existing nodes in place instead of creating new ones. Go back to selecting ISD::DBG_LABEL nodes into TargetInstrInfo::DBG_LABEL nodes instead of leaving them unselected, now that SelectNodeTo allows us to update them in place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53057 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-02Revert r52988. It broke 254.gap on x86-64.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53050 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-02TwoAddressInstructionPass doesn't really require LiveVariables, it just ↵Owen Anderson
needs to update it if it's already around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53049 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-02Add a new getMergeValues method that does not needDuncan Sands
to be passed the list of value types, and use this where appropriate. Inappropriate places are where the value type list is already known and may be long, in which case the existing method is more efficient. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53035 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-02instead of aborting on shifts of i1, just implicitly fold them.Chris Lattner
The dag combiner can produce a shift of i1 when folding icmp i1's. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53030 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-02Let AnalyzeNewNode take care of calling ExpungeNode.Duncan Sands
This makes sure that all new nodes are expunged, not just those the top node of a new subtree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53011 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-01Add a version of AsmPrinter::EOL that takes a const char* so that we don't ↵Owen Anderson
have to do as many implicit std::string constructions. Unfortunately, this doesn't appear to translate to a real speedup in practice. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52981 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52970 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-01Minimize duplicated code in AsmPrinter::printLabel.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52944 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-01Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminatingDan Gohman
the need for a flavor operand, and add a new SDNode subclass, LabelSDNode, for use with them to eliminate the need for a label id operand. Change instruction selection to let these label nodes through unmodified instead of creating copies of them. Teach the MachineInstr emitter how to emit a MachineInstr directly from an ISD label node. This avoids the need for allocating SDNodes for the label id and flavor value, as well as SDNodes for each of the post-isel label, label id, and label flavor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52943 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-30Use a simpler but equivalent form of RecordSource.Dan Gohman

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52930 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30std::ostream and std::string microoptimizations for asm printing.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52929 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30Use reserve.Dan Gohman
SelectionDAG::allnodes_size is linear, but that doesn't appear to outweigh the benefit of reducing heap traffic. If it does become a problem, we should teach SelectionDAG to keep a count of how many nodes are live, because there are several other places where that information would be useful as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52926 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30Rename ISD::LOCATION to ISD::DBG_STOPPOINT to better reflect itsDan Gohman
purpose, and give it a custom SDNode subclass so that it doesn't need to have line number, column number, filename string, and directory string, all existing as individual SDNodes to be the operands. This was the only user of ISD::STRING, StringSDNode, etc., so remove those and some associated code. This makes stop-points considerably easier to read in -view-legalize-dags output, and reduces overhead (creating new nodes and copying std::strings into them) on code containing debugging information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52924 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-30Replace some std::vectors that showed up in heap profiling withDan Gohman
SmallVectors. Change the signature of TargetLowering::LowerArguments to avoid returning a vector by value, and update the two targets which still use this directly, Sparc and IA64, accordingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52917 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-30Correct the allocation size for CCState's UsedRegs member, whichDan Gohman
only needs one bit for each register. UsedRegs is a SmallVector sized at 16, so this eliminates a heap allocation/free for every call and return processed by Legalize on most targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52915 91177308-0d34-0410-b5e6-96231b3b80d8
