2010-03-28now that (parallel) is gone and a variety of bugs in targetsChris Lattner
are cleaned up, we can remove an old fixme. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99741 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-28add an optimized form of OPC_EmitMergeInputChains for the 1, 0 and Chris Lattner
1, 1 cases which are by-far the most frequent. This shrinks the X86 isel table from 77014 -> 74657 bytes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99740 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-28don't add nodes to the now-dead nodes list multiple times, thisChris Lattner
can cause a crash on crazy situations in msp430 when morph-node-to is disabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99739 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-28Improve systemz to model cmp and ucmp nodes as returningChris Lattner
their flags correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99738 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-28fix some modelling problems exposed by a patch I'm working on. bsr/bsf/ptestChris Lattner
nodes all have an EFLAGS result when made by isel lowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99736 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-28don't add flag nodes with chain results to the NowDeadNodesChris Lattner
list multiple times when MorphNodeTo can't be applied. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99735 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-28Oops, r98447 dropped the reference to ForwardType in the wrong place inJeffrey Yasskin
Type::destroy(), so it got skipped for FunctionTypes, StructTypes, and UnionTypes. This fixes the resulting leaks in test/Feature/opaquetypes.ll and test/Integer/opaquetypes_bt.ll. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99732 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-27fix a long standing fixme, which required fixing a bunch of otherChris Lattner
issues to get here. We now trim the result type list of the CompleteMatch or MorphNodeTo operation to be the same size as the thing we're matching. this means that if you match (add GPR, GPR) with an instruction that produces a normal result and a flag that we now trim the result in tblgen instead of having to do it dynamically. This exposed a bunch of inconsistencies in result counting that happened to be getting lucky since the days of the old isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99728 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-27fix CodeGenTarget::getRegisterVTs to not return the Chris Lattner
same vt multiple times for a register. For example, ECX is in 5 different i32 reg classes, just return 1 i32 instead of 5. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99727 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-27hoist some funky logic into CodeGenInstructionChris Lattner
from two places in CodeGenDAGPatterns.cpp, and use it in DAGISelMatcherGen.cpp instead of using an incorrect predicate that happened to get lucky on our current targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99726 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-27continue pushing tblgen's support for nodes with multipleChris Lattner
results forward. We can now handle an instruction that produces one implicit def and one result instead of one or the other when not at the root of the pattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99725 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-27improve -debug-only=isel comments for cases when we don't enter aChris Lattner
scope due to obviously false predicate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99723 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-27fix a bug in my recent patch that increased opcode size to 2 bytes:Chris Lattner
the index comments nested under OPC_SwitchOpcode were off by one. This fixes the comments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99722 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-27Remove another memory leak from ABCD by using Edges by value instead ofJeffrey Yasskin
pointer. There was also a SmallPtrSet whose settiness wasn't being used, so I changed it to a SmallVector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99713 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-27When we promote a load of an argument make sure to take the alignmentEric Christopher
of the previous load - it's usually important. For example, we don't want to blindly turn an unaligned load into an aligned one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99699 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-27Add NVMulSLFrm to represent "3-register multiply with scalar" operations and setJohnny Chen
it as the format for the appropriate N3V*SL*<> classes. These instructions require special handling of the M:Vm field which encodes the restricted Dm and the lane index within Dm. Examples are A8.6.325 VMLA, VMLAL, VMLS, VMLSL (by scalar): vmlal.s32 q3, d2, d10[0] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99690 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-27Thumb2 storeFrom/LoadToStackSlot() need to handle tGPR regs directly, not passJim Grosbach
through to the generic version. The generic functions use STR/LDR, but T2 needs the t2STR/t2LDR instead so we get the addressing mode correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99678 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-26Remove the duplicate multiclass N3VSh_QHSD and use N3VInt_QHSD which is modifiedJohnny Chen
to now take a format argument. N3VDInt<> and N3VQInt<> are modified to take a format argument as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99676 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-26If we mark clean-ups as clean-ups, then it could break when inlining through anBill Wendling
'invoke' instruction. You will get a situation like this: bb: %ehptr = eh.exception() %sel = eh.selector(%ehptr, @per, 0); ... bb2: invoke _Unwind_Resume_or_Rethrow(%ehptr) %normal unwind to %lpad lpad: ... The unwinder will see the %sel call as a clean-up and, if it doesn't have a catch further up the call stack, it will skip running it. But there *is* another catch up the stack -- the catch for the %lpad. However, we can't see that. This is fixed in code-gen, where we detect this situation, and convert the "clean-up" selector call into a "catch-all" selector call. This gives us the correct semantics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99671 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-26Add NVExtFrm to represent NEON Vector Extract Instructions, that uses Inst{11-8}Johnny Chen
to encode the byte location of the extracted result in the concatenation of the operands, from the least significant end. Modify VEXTd and VEXTq classes to use the format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99659 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-26Add N3RegVShFrm to represent 3-Register Vector Shift Instructions, which do notJohnny Chen
follow the N3RegFrm's operand order of D:Vd N:Vn M:Vm. The operand order of N3RegVShFrm is D:Vd M:Vm N:Vn (notice that M:Vm is the first src operand). Add a parent class N3Vf which requires passing a Format argument and which the N3V class is modified to inherit from. N3V class represents the "normal" 3-Register NEON Instructions with N3RegFrm. Also add a multiclass N3VSh_QHSD to represent clusters of NEON 3-Register Shift Instructions and replace 8 invocations with it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99655 91177308-0d34-0410-b5e6-96231b3b80d8
