@IBMJimmyk please take a look ... looks like unexpected shift amount.

zl-wang commented 1 year ago

Actually, looks like IL problem. shift-right by 0.

In the recompilation for FileLock.lockFile, it looks like the problematic trees first appear during Tactical Global Register Allocation. After redundant goto elimination:

n11195n   istore  s3len<auto slot 6>[#916  Auto] [flags 0x3 0x0 ]                             [    0x74ba62449b00] bci=[32,44,1766] rc=0 vc=4904 vn=- li=- udi=121 nc=1
n11196n     iushr (normalizedShift )                                                          [    0x74ba62449b50] bci=[36,15,2120] rc=2 vc=4904 vn=- li=- udi=- nc=2 flg=0x8000

After GRA:

hzongaro commented 1 year ago

Annabelle @a7ehuo, may I ask you to take a look at this issue? It's not clear whether the iushr is being incorrectly marked with the normalizedShift flag by some earlier optimization, or GRA incorrectly thinks the shift amount is zero.

a7ehuo commented 1 year ago

looks like IL problem. shift-right by 0

I'm still going through the recompiled log file. Just trying to understand the issue itself. I came across the following comments on the shift amount range. @zl-wang It looks to me shifting by 0 is allowed. Or maybe I've misunderstood something? I'm still looking for the code that evaluates the right shift by 0 into the instruction with the immediate value 0x20.

zl-wang commented 1 year ago

@a7ehuo it will assert at binary encoding time. right-shift 0 is equal to rotate-left 32 (for 32bit data).

zl-wang commented 1 year ago

if 0 is allowed in language, we should take out the assertion. on the other hand, the IL should be simplified, isn't it?

a7ehuo commented 1 year ago

I'm still looking for the code that evaluates the right shift by 0 into the instruction with the immediate value 0x20.

I think I found the answer to my own question. iushr is evaluated in integerShiftRight. Because rhs is 0 since the second child of iushr is iconst 0, the first immediate value for rlwinm is 0x20 (32 - rhs). @zl-wang Is my understanding correct? I don't see any restriction in integerShiftRight that disallows the value of the second child to be 0 

      int32_t rhs = node->getSecondChild()->getInt() & (operandBits > 32 ? 0x3f : 0x1f);
...
            generateTrg1Src1Imm2Instruction(cg, TR::InstOpCode::rlwinm, node, trg, lhs, (32 - rhs), mask);
...

Ah! I had misread the only description of the meaning of normalizedShift that I could find from OMRSimplifierHelpers.cpp, which says

platforms like PPC need to normalize the shift amount to range (0, 31) before shifting

I took that to be an exclusive range, so 0 and 31 were not allowed - but now I see that doesn't make sense, and the range must be [0, 31]. So, yes, the assertion should go away. Julian @zl-wang, I assume you'll assign the issue.

Annabelle @a7ehuo, may I ask you to open a follow up issue for someone to investigate why the potential simplification is not detected?

zl-wang commented 1 year ago

@IBMJimmyk on a second thought, the binary encoding assertion is still valid, since the instruction itself only allows 5-bit masks. please fix it in the evaluator by special-casing shift-amount 0.

IBMJimmyk commented 1 year ago

Okay, I can do that.

a7ehuo commented 1 year ago

Annabelle @a7ehuo, may I ask you to open a follow up issue for someone to investigate why the potential simplification is not detected?

https://github.com/eclipse-openj9/openj9/issues/17740 is opened to investigate why right shift 0 IL trees are not removed

a7ehuo commented 1 year ago

I'm just wondering what might have changed recently could cause this assert to start happening now. The assert in fillFieldSH5 has been there for three years

IBMJimmyk commented 1 year ago

I opened a PR that should address this issue on the Power evaluator side: https://github.com/eclipse/omr/pull/7057

So a shift right by 0 should be properly encoded once that is merged in. On the optimizer side, it may still be worth looking into why the shift by 0 made it all the way to the end in the IL.

hzongaro commented 1 year ago

Both the results that are mentioned in the previous comment use versions of OMR prior to eclipse/omr#7057's being merged, so I believe they're expected failures.

Jimmy @IBMJimmyk, I believe this issue can be closed now. Do you agree?

IBMJimmyk commented 1 year ago

Yeah. The recently merged fix should address the issues seen so far.

hzongaro commented 1 year ago

Fixed under OMR pull request eclipse/omr#7057
