* Update calling-c-and-fortran-code.md Drop mentioning Cxx.jl
profiling: add Task/GC/Inference/Codegen signposts for Tracy
Referencing control flow statements in value position is illegal
and will cause crashes in compilation or interpretation. Add this
to the verifier, so that downstream tooling that checks for valid
IR can catch this before it gets handed off to the compiler.
irverify: Catch invalid use of Goto{IfNot, Node}, ReturnNode
* gf: add `max_varargs` field to jl_method_t

This field is currently always configured to use the existing heuristic,
which is based on specializing to the max # of args appearing in other
methods for the same function.

This makes progress on #49172. It leaves for later:
  1. Go back and change the places we manually tweak `max_args` to set
     `max_varargs` on the relevant method(s) instead.
  2. Re-visit the original heuristic, to see if it can be better defined
     without "spooky action at a distance" based on other method defs.

* Initialize purity bits

* gf: re-factor `get_max_varargs` to separate function

* Update src/gf.c

* Revert "Update src/gf.c"

This reverts commit a12c4f9.

Removes some overly strict `@test_throws MethodError` for calls with
`Union{}` or `Any`, in preparation for making those errors more precise.
Make Type{Union{}} in method definitions always the most specific type
(normally these would end up being ambiguous). This ensures we do not
invalidate them, nor need to consider ambiguities that might arise from
intersections with them.
Based on the new morespecific rule for Union{} and method definitions of
the specific form `f(..., Type{Union{}}, Vararg)`. If a method
definition exists with that specific form, the intersection visitor will
ignore all intersections that have that as their only result, saving
significant effort when working with lookups involving `Type{<:T}`
(which usually ended up mostly ambiguous anyways).

Fixes: #33780

This pattern turns out to have still to been making package loading
slow. We could keep adding methods following the ambiguity pattern
#46000 for the couple specific
functions that need it (constructor, eltype, IteratorEltype,
IteratorSize, and maybe a couple others) so the internals can detect
those and optimize functions that have that method pair. But it seems
somewhat odd, convoluted, and non-obvious behavior there. Instead, this
breaks all ambiguities in which Union{} is present explicitly in favor
of the method with Union{}. This means that when computing method
matches, as soon as we see one method definition with Union{}, we can
record that the method is the only possible match for that slot.

This, in essence, permits creating a rule for dispatch that a TypeVar
lower bound must be strictly a supertype of Union{}, but this creates it
at the function level, instead of expecting the user to add it to every
TypeVar they use to define methods.

This also lets us improve the error message for these cases (generally
they should error to avoid polluting the inference result), since we can
be assured this method will be called, and not result in an ambiguous
MethodError instead!

Reverts the functional change of #46000
Since T cannot be Union{} here, the prior optimization would not get
detected post facto, but a priori this cannot be inhabited for
T=Union{}, so we can exclude it immediately. This does not happen during
inference, but shows up during edge validation somewhat often.
A fused multiply-add is available in MPFR as `mpfr_fma` and `Base.fma`
already uses it. Apart from being fused (more accurate), it's also more
performant than the generic `muladd` and allocates one less temporary
`BigFloat`.

Certain queries were searching for Type{T} instead of T due to a
mistaken tparam setting, resulting in missing methods in lookup.

Fix #49408
Ref #48925
add morespecific rule for Type{Union{}}
…ion{}} otherwise (#49393)

This was a primary motivation for #49111. Previously, we'd see some
some method specializations such as `convert(::Type{T}, ::T) where
T<:Float64` (apparently from inference of some tuple convert
specializations), which were not necessary to have.
Code should normally preserve values, not the types of values. This
ensures the user can define styles with metadata, and requires less
type-parameter-based programming, but rather can focus on the values.
Even if we have a new method that is more specific than the method it is
replacing, there still might exist an existing method that is more
specific than both which already covers their intersection.

An example of this pattern is adding
    Base.IteratorSize(::Type{<:NewType})
causing invalidations on
    Base.IteratorSize(::Type)
for specializations such as
    Base.IteratorSize(::Type{<:AbstractString})
even though the intersection of these is fully covered already by
    Base.IteratorSize(::Type{Union{}})
so our new method would never be selected there.

This won't detect ambiguities that already cover this intersection, but
that is why we are looking to move away from that pattern towards
explicit methods for detection in closer to O(n) instead of O(n^2): #49349.

Similarly, for this method, we were unnecessarily dropping it from the
MethodTable cache. This is not a significant latency problem (the cache
is cheap to rebuild), but it is also easy to avoid in the first place.

Refs #49350
…ure (#49404)

Inference should have already made this edge from this item, so we do
not want to add another wider edge. Even if this target object contains
some invalid code later, inference already showed that does not affect
our code-paths, so we don't need or want that wide edge.

#47154 mistakenly added `@_safeindex` macro on the
`_append!(a::AbstractVector, ::Union{HasLength,HasShape}, iter)` method,
although `@_safeindex` is only valid for builtin vectors i.e. `Vector`.

This commit adds `isa` check so that `@_safeindex` is only applied to
builtin vectors. The `isa` check should be removed at compile time, so
it should not affect the runtime performance.

closes #49748
This feature was already shipped with 1.9 so it probably shouldn't be mentioned a second time in the 1.10 NEWS.md.
…nt's load path (#49701)

This ordering of the algorithm abandons the elegant insertion in favor
of using another copy of Tarjan's SCC code. This enables us to abort the
algorithm in O(k*n) time, instead of always running full O(n*n) time,
where k is `min(lim,n)`.

For example, to sort 1338 methods:

Before:
julia> @time Base._methods_by_ftype(Tuple{typeof(Core.kwcall), NamedTuple, Any, Vararg{Any}}, 3, Base.get_world_counter());
  0.136609 seconds (22.74 k allocations: 1.104 MiB)
julia> @time Base._methods_by_ftype(Tuple{typeof(Core.kwcall), NamedTuple, Any, Vararg{Any}}, -1, Base.get_world_counter());
  0.046280 seconds (9.95 k allocations: 497.453 KiB)
julia> @time Base._methods_by_ftype(Tuple{typeof(Core.kwcall), NamedTuple, Any, Vararg{Any}}, 30000, Base.get_world_counter());
  0.132588 seconds (22.73 k allocations: 1.103 MiB)
julia> @time Base._methods_by_ftype(Tuple{typeof(Core.kwcall), NamedTuple, Any, Vararg{Any}}, 30000, Base.get_world_counter());
  0.135912 seconds (22.73 k allocations: 1.103 MiB)

After:
julia> @time Base._methods_by_ftype(Tuple{typeof(Core.kwcall), NamedTuple, Any, Vararg{Any}}, 3, Base.get_world_counter());
  0.001040 seconds (1.47 k allocations: 88.375 KiB)
julia> @time Base._methods_by_ftype(Tuple{typeof(Core.kwcall), NamedTuple, Any, Vararg{Any}}, -1, Base.get_world_counter());
  0.039167 seconds (8.24 k allocations: 423.984 KiB)
julia> @time Base._methods_by_ftype(Tuple{typeof(Core.kwcall), NamedTuple, Any, Vararg{Any}}, 30000, Base.get_world_counter());
  0.081354 seconds (8.26 k allocations: 424.734 KiB)
julia> @time Base._methods_by_ftype(Tuple{typeof(Core.kwcall), NamedTuple, Any, Vararg{Any}}, 30000, Base.get_world_counter());
  0.080849 seconds (8.26 k allocations: 424.734 KiB)

And makes inference faster in rare cases (this particular example came
up because the expression below occurs appears in `@test`
macroexpansion), both before loading loading more packages, such as
OmniPackage, and afterwards, where the cost is almost unchanged
afterwards, versus increasing about 50x.

julia> f() = x(args...; kwargs...); @time @code_typed optimize=false f();
  0.143523 seconds (23.25 k allocations: 1.128 MiB, 99.96% compilation time) # before
  0.001172 seconds (1.86 k allocations: 108.656 KiB, 97.71% compilation time) # after
This now chooses the optimal SCC set based on the size of lim, which
ensures we can assume this algorithm is now << O(n^2) in all reasonable
cases, even though the algorithm we are using is O(n + e), where e may
require up to n^2 work to compute in the worst case, but should require
only about n*min(lim, log(n)) work in the expected average case.

This also further pre-optimizes quick work (checking for existing
coverage) and delays unnecessary work (computing for *ambig return).
This commit includes a bit of refactoring of `Base.aligned_sizeof` to
make it more inference-friendly, especially in cases like
`Base.aligned_sizeof(::Union{DataType,Union})`.

In particular, it eliminates the chance of inference accounting for a
method error of `datatype_alignment(::Union)` in the second branch.

xref: <aviatesk/JET.jl#512>
This is yet another followup to #49692 and #49750.
With the introduced change, we kill the CFG edge
from the basic block with the discovered error to
its successors. However, we have an invariant in
the verifier that the CFG should always match the
IR. Turns out this is for good reason, as we assume
in a number of places (including, ironically in the
irinterp) that a GotoNode/GotoIfNot terminator means
that the BB has the corresponding number of successors
in the IR. Fix all this by killing the rest of the basic
block when we discover that it is unreachable and if
possible introducing an unreachable node at the end.
However, of course if the erroring statement is the
fallthrough terminator itself, there is no space for
an unreachable node. We fix this by tweaking the
verification to allow this case, as its really
no worse than the other problems with fall-through
terminators (#41476), but of course it would be good
to address that as part of a more general IR refactor.
- atexit(f) mutates global shared state.
- atexit(f) can be called anytime by any thread.
- Accesses & mutations to global shared state must be locked if they can
  be accessed from multiple threads.

Add unit test for thread safety of adding many atexit functions in
parallel
reorder ml-matches to avoid catastrophic performance case
jitlayers: move the local dylibs ahead of the global one
If a fall-through terminator was already Bottom, we should not attempt
to rekill the successor edge, because it was already deleted.
Yet another fix in the #49692, #49750, #49797 series, which is
turning out to be quite a rabit hole. Also fix a typo in the
verifer tweak where we were looking at the BB idx rather than
the terminator idx.

`@something` eagerly unwraps any `Some` given to it, while keeping the
variable between its arguments the same. This can be an issue if a
previously unpacked value is used as input to `@something`, leading to a
type instability on more than two arguments (e.g. because of a fallback
to `Some(nothing)`). By using different variables for each argument,
type inference has an easier time handling these cases that are isolated
to single branches anyway.

This also adds some comments to the macro, since it's non-obvious what
it does.

Benchmarking the specific case I encountered this in led to a ~2x
performance improvement on multiple machines.
