[zl-wang]

@midronij fpr13 is GRA assigned to a scalar single-precision FP. VMX vor was generated using that FPR.

[midronij]

I think the problem here isn't with GRA (although my recent changes are what exposed it). If you take a look at where fp13 gets allocated during GRA, it's for a FloatVector symbol, which isn't incorrect (since for FP-type vectors, we can use VSRs 0-31). Instead, the issue is that when a virtual register is originally allocated for this symbol, it is designated as a VMX register. If you go a little further up the generated assembly code, you can see the following:

 [    0x7b5c571544b0]   19      xscvdpsp        vsr40, vsr16
 [    0x7b5c57154550]   19      xxspltw         vsr40, vsr40, 0   <<< contents of vr8 set here (since vr8 = vsr40)
 [    0x7b5c571546d0]   0       li      gr3, 0000000000000008
 [    0x7b5c57154770]   0       stxvw4x         [gr8, gr3], vsr40
 .
 .
 .
 [    0x7b5c576bc9a0]   0       vor     fp13, vr8, vr8            <<< try to copy vr8 to fp13 (ASSERTION FAILS HERE)

These instructions are generated for this tree:

 n3357n   (  4)    vsplatsVector128Float (in VRF_0318) ()                                             [    0x7b5d7f320910] bci=[25,19,3692] rc=4 v

 n11828n  (  3)                ==>iRegLoad (in GPR_0275) (X>=0 cannotOverflow SeenRealReference )

And in particular, you can see that the xxspltw instruction, where the contents of vr8 are set, is expecting a VMX register:

 [    0x7b5c57154360]   19      xscvspdpn       FPR_0312, FPR_0312
 [    0x7b5c571544b0]   19      xscvdpsp        VRF_0318, FPR_0312
 [    0x7b5c57154550]   19      xxspltw         VRF_0318, VRF_0318, 0   <<< src/target reg is a VRF

Taking a look at vsplatsEvalutor() for Float, we can see that we allocate a VMX register for the resulting value:

    } else if (node->getDataType().getVectorElementType() == TR::Float) {
        TR::Register *srcReg = cg->evaluate(child);
        TR::Register *trgReg = cg->allocateRegister(TR_VRF);

        generateTrg1Src1Instruction(cg, TR::InstOpCode::xscvdpsp, node, trgReg, srcReg);
        generateTrg1Src1ImmInstruction(cg, TR::InstOpCode::xxspltw, node, trgReg, trgReg, 0);

        node->setRegister(trgReg);
        cg->decReferenceCount(child);
        return trgReg;
    }

(from omr/compiler/p/codegen/FPTreeEvaluator.cpp#L435-L445

As a result, when we need to copy the vsplats result value into fp13, we end up generating vor, since the register we're copying from (vr8) is designated as a VMX register. If you modify vsplatsEvalutor() to allocate a VSX register instead (i.e.: TR::Register *trgReg = cg->allocateRegister(TR_VSX_VECTOR);), the failure no longer occurs, since we now use xxlor to copy into fp13 (which is also vsr13):

 [    0x73d5d68bf830]   0       xxlor   vsr13, vsr16, vsr16

To ensure that this failure doesn't happen elsewhere, we'll need to make similar changes for any other vector evaluators when the element type is Float or Double. I'll link the PR once I've done that.

@gita-omr this may be of interest to you, since it's similar to the VSX/VMX register issue we were dealing with before

[zl-wang]

it sounds like more consistent anyway: floating types use VSX registers.
the other potential improvement is: who generates that vor? is it a side-effect of register assigning or codegen functionally gen it? looking into why it didn't choose wider-applicable (but equivalent) xxlor and fixing that as well.

[midronij]

As you said, I think it's a side affect of how the registers were assigned. In this case, the vor is generated during register assignment by registerCopy() (in omr/compiler/p/codegen/OMRMachine.cpp). I don't know if there's some particular reason vor was used here originally, but I don't see any reason why xxlor wouldn't work just as well and reduce the risk of problems like this happening again. I'll go ahead and fix that as well.

[0xdaryl]

We haven’t had an OMR promote in nearly two weeks. My understanding is that this is the remaining issue holding it up. Can the (seemingly minor) reviewer comments in eclipse-omr/omr#8304 be addressed today so this can be merged? @midronij Thanks.

[hzongaro]

We haven’t had an OMR promote in nearly two weeks.

FYI - started a new OMR acceptance build after merging eclipse-omr/omr#8304.
