jeroen.dobbelaere added a comment to D91576: [MemCpyOpt] Correctly merge alias scopes during call slot optimization.

Unless there's something that makes this issue specific to the call slot optimization, wouldn't it be better to adjust the logic in MDNode::getMostGenericAliasScope() to ensure that any code performing alias scope merging is covered?

Hi Modi,

jeroen.dobbelaere added a comment to D91250: Support intrinsic overloading on unnamed types.

I think we would also need tests for combining multiple modules with intrinsics with unnamed type.

If the module owns the numbering, can encounter name/type clashes, e.g. if 2 modules have unnamed types that are different. i.e. both have declare %0* @llvm.ssa.copy.p0s_s.0(%0* returned) ,but %0 is defined as different types in both modules ?

This is indeed a good suggestion. I am adding a link test (and it does bring up a case that I did not foresee, so I am also fixing it).

I would like to propose this version for review. As far as I am aware, this version should not suffer from the objections made in D48541. Also a testcase has been included.

jeroen.dobbelaere updated the diff for D91250: Support intrinsic overloading on unnamed types.

This new version uses a different approach: we now work by 'uniquifying' the initial BaseName of an intrinsic mangled named when it is based on an anonymous struct.

jeroen.dobbelaere added a comment to D91250: Support intrinsic overloading on unnamed types.

Is this the same idea as in D48541 (linked from PR38117), where we use LLVMContext to keep track of IDs for anonymous types? If that's the case, the same objections as for D48541 probably apply here as well. I think one of the problems is that the names we assign depend on the order different modules are loaded.

jeroen.dobbelaere added a comment to D90104: [LoopUnroll] Duplicate noalias metadata.

@jeroen.dobbelaere: Yeah, I'm aware of that. However, the full restrict patches are a large change that has stalled for a long time, so I think we need to address the miscomples in a simple way in the meantime. I was also wondering if it might not make sense to split up the full restrict patches in a way that addresses individual problems without having to land the full machinery in one go. For example, by first introducing the noalias.decl function only, which is I believe the only part that's relevant for this particular problem.

jeroen.dobbelaere added a comment to D90104: [LoopUnroll] Duplicate noalias metadata.

It would make sense to add comments in the code to explain _why_ this is needed and why it is safe to do.
note: the transformation should be correct, as the unrolled version might now 'alias' with usages of the original scopes that are outside the loop.

  • aka, this will be a pessimization for some use cases (those where the cloning should not be needed)
  • for reference, D68510 is the patch in the 'full restrict patchset' (D68484) that adds similar, but more complete suport.

I think variant 1 is the obvious winner.
Though while i'm not familiar with the code, i'm not sure why you'd need to move args around - can't ptr_provenance be added as a new last 'argument'?

jeroen.dobbelaere added a comment to D68488: [PATCH 03/27] [noalias] [IR] Introduce ptr_provenance for LoadInst/StoreInst.

I have 3 variants of this patch:

  • variant 0 : always reserve place for the ptr_provenance; Introduce NumOfOperandsDelta to get the correct number of operands
    • extra space overhead for load/store instructions;
    • extra instruction overhead for ALL instructions ('getNumOperand()');
    • low overhead when adding/removing ptr_provenance
    • NOTE: this is the current provided patch
  • variant 1 : always reserve place for the ptr_provenance; Move arguments around when adding/removing ptr_provenance
    • extra space overhead for load/store instructions;
    • NO impact on other instructions;
    • slightly more overhead when accessing operands of load/store instructions;
    • medium overhead when adding/removing ptr_provenance
  • variant 2 : Have a LoadInst, LoadWithProvInst and StoreInst, StoreWithProvInst. Only the 'WithProv' variant reserves place for optional argument. When the ptr_provenance is added, it can involve creating a Load/StoreWithProv based on the original Load/Store. Adding/removing the ptr_provenance argument involves moving arguments around.
    • extra space only needed when we know we will need it.
    • NO impact on other instructions;
    • slightly more overhead when accessing operands of load/store instructions;
    • medium to high overhead when adding ptr_provenance. medium when removing it.
    • higher risk in keeping things correct in optimization: adding the ptr_provenance can require recreating the Load/Store instruction. This might be difficult if the optimization pass is tracking pointers to the original Load/Store instruction.
    • main benefit: almost no impact from this change if the feature is not used (aka -fno-full-restrict)

The performance impact of different parts of this patch can be seen here: https://llvm-compile-time-tracker.com/index.php?branch=dobbelaj-snps/perf/test_instructions_20200907-01

  • Introducing the 'NumUserOperandsDelta' has a measurable impact on the number of instructions as it affects every instruction. Maybe that can be avoided ?
  • Introducing the optional extra argument for LoadInst/StoreInst has (as expected) some effect on the RSS.

jeroen.dobbelaere added a comment to D62731: Add support for options -frounding-math, -ftrapping-math, -ffp-model=, and -ffp-exception-behavior=, : Specify floating point behavior.
