c731edb | Shuhei Kadowaki | 07 December 2023, 01:57:47 UTC | irinterp: skip `nothing` statement when analyzing `:nothrow` and `:noub` (#52417) This commit makes irinterp skip `nothing` statements when looking through `:nothrow` and `:noub` flags of all statements. This is necessary since `nothing` can be inserted as a dummy node, e.g. to prevent CFG change by `finish_current_bb!`, without explicitly marking it as `IR_FLAG_NOTHROW`. Alternatively, rather than altering irinterp, it might be better to mark `IR_FLAG_NOTHROW` (and maybe even `IR_FLAG_EFFECT_FREE` and other flags too) where those `nothing` statements are inserted. But I wasn't confident that this would address all scenarios or if it's the best way to go, so this commit opts for the previously mentioned symptomatic approach. | 07 December 2023, 01:57:47 UTC |

I have not seen proof of this reaching a failure, but we do appear to be missing this ordering specification in visual review. Should not make a difference to generated code on x86, which already has TSO guaranteed, but may alter optimizations and other CPUs with weaker memory orderings. | 06 December 2023, 15:35:44 UTC |

This fixes that by iteratively going through the characters of the hint until reaching that which marks the end of the input. | 06 December 2023, 05:10:09 UTC |
f96585b | Shuhei Kadowaki | 06 December 2023, 05:03:06 UTC | reflection: refactor `@assume_effects` implementation (#52399) I am working on implementing a support for callsite `@assume_effects` annotation, and this update is part of the preparation for that goal. Along this, I've modified the API from `pushmeta!(::Expr, ::Symbol, args...)` to `pushmeta!(::Expr, ::Union{Symbol,Expr})`. This change isn't breaking as long as the `args` are empty, which is the case for most use cases (actually there is only one usage of `pushmeta!` with non-empty `args` within Julia base). I've verified on JuliaHub, and there don't appear to be any packages using `pushmeta!` with non-empty `args`, so there shouldn't be any (big) issues. | 06 December 2023, 05:03:06 UTC |

d0e7ec0 | Jishnu Bhattacharya | 05 December 2023, 14:54:41 UTC | Adjoint for vectors may use trailing axes of the parent (#52379) Close #52373, or at least the part that may be addressed here. After this, the first axis for an `Adjoint(parent::AbstractVector)` will be the second axis of the `parent`. This will change the type of the axis where the parent array type specializes `axes(A, d)`. In the short term, this would improve type-stability in cases such as ```julia julia> A = OffsetArray([1,2], 2); julia> @code_typed axes(A')[1] CodeInfo( 1 ─ %1 = $(Expr(:boundscheck))::Bool │ %2 = Base.getfield(t, i, %1)::OffsetArrays.IdOffsetRange{Int64, Base.OneTo{Int64}} └── return %2 ) => OffsetArrays.IdOffsetRange{Int64, Base.OneTo{Int64}} ``` where the result is now concretely inferred instead of being a small `Union`. In principle, with https://github.com/JuliaArrays/StaticArrays.jl/pull/916, this would make the axes of the adjoint of a `StaticVector` statically sized. | 05 December 2023, 14:54:41 UTC |

b69398a | Jishnu Bhattacharya | 04 December 2023, 03:08:55 UTC | Integer matrix exponentiation in schurpow (#51992) This improves type-inference by avoiding recursion, as the `A^p` method calls `schurpow` if `p` is a float. After this, the result of `schurpow` is inferred as a small `Union`: ```julia julia> @inferred Union{Matrix{ComplexF64}, Matrix{Float64}} LinearAlgebra.schurpow([1.0 2; 3 4], 2.0) 2×2 Matrix{Float64}: 7.0 10.0 15.0 22.0 ``` One concern here might be that for large `p`, the `A^Int(p)` computation might be expensive by repeated multiplication, as opposed to diagonalization. However, this may only be the case for really large `p`, which may not be commonly encountered. I've added a test, but I'm unsure if `schurpow` is deemed to be an internal function, and this test is unwise. Unfortunately, the return type of `A^p` isn't concretely inferred yet as there are too many possible types that are returned, so I couldn't test for that. | 04 December 2023, 03:08:55 UTC |

58c1d51 | Shuhei Kadowaki | 01 December 2023, 00:12:35 UTC | [REPLCompletions] fix #52099 by adjusting effects of `HAMT` methods (#52331) After looking into #52099, I discovered that it has the same root cause as #51548. Essentially, when a method that's not `!effect_free` is applied to a `Const` value concretized by the `REPLInterpreter`'s aggressive inference, since the `!effect_free` method will not be concretized, it will eventually lead to the `Const` representing unexpected object being returned. This commit tries to fix the specific problem reported in #52099 by enhancing the effects of `Base.HAMT` methods, so they're concrete-evaled. Admittedly, this is more of a quick fix than a complete solution, and not the best one, but it was the simplest. A better solution might involve implementing EA's handling of `Memory`-objects that allows the compiler to automatically prove `:effect_free` in more scenarios. But this would need a bigger overhaul, so I plan to tackle it in another PR. | 01 December 2023, 00:12:35 UTC |

A pointer in a `"r"` constraint does not imply that the pointed-to memory is also an input. You could just use memory operands (or the `_mm_crc32_u64` intrinsic), but if you want to force the addressing mode you can use a dummy memory operand like `asm("crc32 (%1),%0 " : "+r"(crc0) : "r"(next), "m" (*(const char (*)[24]) pStr) )`;. Inlining or LTO could break this. See [at&t asm inline c++ problem](https://stackoverflow.com/posts/comments/81680441) (which needs an update: pointer-to-array is cleaner than a struct with a flexible array member).

df40bab | Hendrik Ranocha | 28 November 2023, 12:19:12 UTC | fix invalidations related to `ismutable` (#52170) Related to #52134. It would be nice if the underlying inference issue was fixed but this seems to be a hotfix for now. I have seen this inference problem occurring in Julia v1.9, v1.10, and current `master`. For example, on Julia v1.9.3, I get ```julia julia> code_warntype(ismutable, (Function,)) MethodInstance for ismutable(::Function) from ismutable(x) @ Base reflection.jl:521 Arguments #self#::Core.Const(ismutable) x::Function Body::Any 1 ─ nothing │ nothing │ %3 = Base.typeof(x)::Type{<:Function} │ %4 = Base.getproperty(%3, :name)::Any │ %5 = Base.getproperty(%4, :flags)::Any │ %6 = (%5 & 0x02)::Any │ %7 = (%6 == 0x02)::Any └── return %7 ``` This causes some invalidations when `using OrdinaryDiffEq`. | 28 November 2023, 12:19:12 UTC |

5b2fcb6 | Keno Fischer | 27 November 2023, 17:01:53 UTC | Compiler support for optimizing PersistentDict (#51993) This is part of the work to address #51352 by attempting to allow the compiler to perform SRAO on persistent data structures like `PersistentDict` as if they were regular immutable data structures. These sorts of data structures have very complicated internals (with lots of mutation, memory sharing, etc.), but a relatively simple interface. As such, it is unlikely that our compiler will have sufficient power to optimize this interface by analyzing the implementation. We thus need to come up with some other mechanism that gives the compiler license to perform the requisite optimization. One way would be to just hardcode `PersistentDict` into the compiler, optimizing it like any of the other builtin datatypes. However, this is of course very unsatisfying. At the other end of the spectrum would be something like a generic rewrite rule system (e-graphs anyone?) that would let the PersistentDict implementation declare its interface to the compiler and the compiler would use this for optimization (in a perfect world, the actual rewrite would then be checked using some sort of formal methods). I think that would be interesting, but we're very far from even being able to design something like that (at least in Base - experiments with external AbstractInterpreters in this direction are encouraged). This PR tries to come up with a reasonable middle ground, where the compiler gets some knowledge of the protocol hardcoded without having to know about the implementation details of the data structure. The basic ideas is that `Core` provides some magic generic functions that implementations can extend. Semantically, they are not special. They dispatch as usual, and implementations are expected to work properly even in the absence of any compiler optimizations. However, the compiler is semantically permitted to perform structural optimization using these magic generic functions. In the concrete case, this PR introduces the `KeyValue` interface which consists of two generic functions, `get` and `set`. The core optimization is that the compiler is allowed to rewrite any occurrence of `get(set(x, k, v), k)` into `v` without additional legality checks. In particular, the compiler performs no type checks, conversions, etc. The higher level implementation code is expected to do all that. This approach closely matches the general direction we've been taking in external AbstractInterpreters for embedding additional semantics and optimization opportunities into Julia code (although we generally use methods there, rather than full generic functions), so I think we have some evidence that this sort of approach works reasonably well. Nevertheless, this is certainly an experiment and the interface is explicitly declared unstable. ## Current Status This is fully working and implemented, but the optimization currently bails on anything but the simplest cases. Filling all those cases in is not particularly hard, but should be done along with a more invasive refactoring of SROA, so we should figure out the general direction here first and then we can finish all that up in a follow-up cleanup. ## Obligatory benchmark Before: ``` julia> using BenchmarkTools julia> function foo() a = Base.PersistentDict(:a => 1) return a[:a] end foo (generic function with 1 method) julia> @benchmark foo() BenchmarkTools.Trial: 10000 samples with 993 evaluations.

cd4f49a | Keno Fischer | 26 November 2023, 20:30:58 UTC | Give a better assertion failure for module serialization issues (#52306) This issue confused me for a few hours. Basically what happened was that I had some IR that verified fine, but did not survive a deserialization round-trip (related to mismatching pointer types, which of course are starting to lose their meaning in LLVM). In this situation, the first assertion hit was the failure to verify the LLVM module at the output, but I had a hard time figuring out where this IR was coming from, since it looked totally corrupted. If LLVM assertions had been enabled, I would have seen the cantFail give a proper error, but since I only had Julia assertions enabled, I did not see this error message. Try to improve this situation by also asserting the absence of serialization errors using Julia assertions, not just LLVM assertions. | 26 November 2023, 20:30:58 UTC |

6e23543 | Keno Fischer | 24 November 2023, 15:26:51 UTC | Fix off-by-2 in codegen (#52292) This is cherry-picked from #52245. This is an independent bugfix, and looks like #52245 might need another round of discussion. There were two separate off-by-1's in the codegen code that is trying to detect assignments to slots inside try/catch regions. First, it was asking to include the value of the catch label, which is actually the first statement *not* in the try region. Second, there was a confusion of 0 and 1 based indexing in the iteration bounds. The end result of this was that the code was also looking at the first two statements of the catch region. This wasn't a problem before #52245 (other than a potentially over-conservative marking of some slots as volatile), because our catch blocks always had at least two statements (a :leave and a terminator), but with the `:leave` change, it is possible to have catch blocks with only one statement. If these happened to be at the end of the function, things would blow up. As a side node, this code isn't particularly sound, because it assumes that try/catch regions are lexical, which they are not. The assumption happens to work out ok for the code we generate in the frontend and optimized IR doesn't have slots, so we don't use this code, but it is not in general sound. | 24 November 2023, 15:26:51 UTC |

0c46852 | Shuhei Kadowaki | 23 November 2023, 08:00:46 UTC | effects: refine `:nothrow` when `exct` is known to be `Bottom` (#52270) Implements effects refinement that goes in the reverse direction of what was implemented in 8dd0cf5. In the discussion at JuliaLang/julia#52268, there's a debate on how to deal with exceptions like `StackOverflowError` or `InterruptException` that are caused by environment. The original purpose of #52268 was to fix issues where methods that could cause a `StackOverflowError` were mistakenly refined to `:nothrow`. But now it feels like it's a bit weird to model such environment-dependent exceptions as `:nothrow` in the first place. If we can exclude environment-dependent errors from the `:nothrow` modeling, those methods might be safely considered `:nothrow`. To prevent the concrete evaluation of methods that may cause `StackOverflowError`, it's enough to taint its `:teminates` after all. This commit excludes environment-depending errors from the `:nothrow` modeling, reverting the changes from #52268 while making it explicit in the `Effects` and `Base.@assume_effects` docstrings. Anyway, now the compile is able to prove `:nothrow`-ness of the following frame: ```julia function getindex_nothrow(xs::Vector{Int}, i::Int) try return xs[i] catch err err isa BoundsError && return nothing rethrow(err) end end ``` | 23 November 2023, 08:00:46 UTC |

c8ca350 | Keno Fischer | 19 November 2023, 22:11:17 UTC | inference: Model type propagation through exceptions (#51754) Currently the type of a caught exception is always modeled as `Any`. This isn't a huge problem, because control flow in Julia is generally assumed to be somewhat slow, so the extra type imprecision of not knowing the return type does not matter all that much. However, there are a few situations where it matters. For example: ``` maybe_getindex(A, i) = try; A[i]; catch e; isa(e, BoundsError) && return nothing; rethrow(); end ``` At present, we cannot infer :nothrow for this method, even if that is the only error type that `A[i]` can throw. This is particularly noticable, since we can now optimize away `:nothrow` exception frames entirely (#51674). Note that this PR still does not make the above example particularly efficient (at least interprocedurally), though specialized codegen could be added on top of this to make that happen. It does however improve the inference result. A second major motivation of this change is that reasoning about exception types is likely to be a major aspect of any future work on interface checking (since interfaces imply the absence of MethodErrors), so this PR lays the groundwork for appropriate modeling of these error paths. Note that this PR adds all the required plumbing, but does not yet have a particularly precise model of error types for our builtins, bailing to `Any` for any builtin not known to be `:nothrow`. This can be improved in follow up PRs as required. | 19 November 2023, 22:11:17 UTC |

I believe, even without #52169, uninitialized field does not inherently leads to UB, but just causes inconsistency of the program, since what actually causes UB is `getfield` that accesses into whatever object, but not the allocation itself. | 19 November 2023, 15:50:33 UTC |
