With DOTNET_JitStress=2 and DOTNET_JitStressRegs=8 we hit this assert in some of the Swift tests.

ISSUE: <ASSERT> #16 C:\dev\dotnet\runtime\src\coreclr\jit\lsra.cpp (7418) - Assertion failed 'parent->OperGet() == oper' in 'SwiftRetAbiStress:TestSwiftRetFunc0()' during 'LSRA allocate' (IL size 95; hash 0xbcced63c; Tier0)

When we hit the assert, the LIR looks like the following:

N070 ( 14,  5) [000038] --CXG-----Z                   t38 = ▌  CALL unman struct SwiftRetAbiStress:SwiftRetFunc0():SwiftRetAbiStress+S0 REG rax,rdx,rcx

The refPosition has refPosition->reload == 1, but the parent node (of [000038]) is a GT_COPY.

I've attached an SPMI collection that repros the assertion on commit 0ea9b8f with clrjit_unix_x64_x64.dll -- pass -c 16.

Looks like it doesn't require JitStress, just JitStressRegs=8:

We define 3 multi-reg for SwiftRetAbiStress:SwiftRetFunc0():SwiftRetAbiStress+S0. At the use, we do not get same registers for all 3 of them and so we need to insert GT_COPY. 2 of the registers are not spilled and hence COPY suffice, but for 3rd, we spilled it and hence have to RELOAD it (to a different register) at the use.

At the use, we create this single tree node GenTreeCopyOrReload and set multiRegIdx for the 3 registers. However, for the 3rd register (which is RELOAD), we cannot use the logic of GT_COPY and emit the mov, but need to reload it from the stack. If we ignore the fact that GT_COPY is required for the 3rd register and let GT_RELOAD continue, I wanted to see where it goes wrong, but unfortunately the superpmi collection I have seems outdated and it failed with MISSING: Method context 16 failed to replay: SuperPMI assertion failed (missing key "key" in map GetHelperFtn): key 82. Probably I will need to try reproing on osx/x64 directly and test out few theories.

I am also wondering why we did not see similar situation in the past or perhaps the jitstressregs were restricting it from limiting the available regs under stress, making this situation less common or undiscovered.

If we ignore the fact that GT_COPY is required for the 3rd register and let GT_RELOAD continue

It turns out, we do mark the entire tree spilled when one or more allocated registers are spilled

runtime/src/coreclr/jit/lsra.cpp

Lines 8176 to 8185 in 28c39bc

// In case of multi-reg node, also set spill flag on the
// register specified by multi-reg index of current RefPosition.
// Note that the spill flag on treeNode indicates that one or
// more its allocated registers are in that state.
if (treeNode->IsMultiRegNode())
{
treeNode->SetRegSpillFlagByIdx(GTF_SPILL, currentRefPosition->getMultiRegIdx());
}
}

and during unspill, already take care of that.

runtime/src/coreclr/jit/codegenlinear.cpp

Lines 2117 to 2129 in 28c39bc

// In case of multi-reg node, spill flag on it indicates that one or more of its allocated regs need to
// be spilled, and it needs to be further queried to know which of its result regs needs to be spilled.
const unsigned regCount = tree->GetMultiRegCount(compiler);
for (unsigned i = 0; i < regCount; ++i)
{
GenTreeFlags flags = tree->GetRegSpillFlagByIdx(i);
if ((flags & GTF_SPILL) != 0)
{
regNumber reg = tree->GetRegByIndex(i);
regSet.rsSpillTree(reg, tree, i);
gcInfo.gcMarkRegSetNpt(genRegMask(reg));
}

As such the assert in the issue is not needed. I verified that the registers marked as COPY vs. RELOAD are retrieved accurately at the use:
