* Fix ctors for Realization (#6675)
For vector-of-Buffers, the ctor took a non-const ref to the argument, which was weird and nonsensical. Replaced with a const-ref version and and an rvalue-ref version; it turns out that literally *all* of the internal calls were able to use the latter, trivially saving some copies.

* Upgrade to clang-format 13 (#6689)
Goal here: eliminate the need for a local version of llvm/clang-12, and don't stay too far behind the toolchain.
As always, clang-format doesn't promise backwards compatibility, but the main differences in formatting are:
- more regularization of spaces at the start of comments (I like this change)
- minor difference of formatting of function-pointer-type declarations (not a fan of this, but I can't find a way to disable it and it's only really used in a handful of place in the Python bindings)

* Python: make Func implicitly convertible to Stage (#6702) (#6704)
This allows for `compute_with` and `rfactor` to work more seamlessly in Python.
Also:
- Move two compute_with() variant bindings from PyFunc and PyStage to PyScheduleMethods, as they are identical between the two
- drive-by removal of redundant `py::implicitly_convertible<ImageParam, Func>();` call

* Remove the last remaining call to getPointerElementType() (#6715)
* Remove the last remaining call to getPointerElementType()
LLVM is moving to opaque pointers, we must have missed this one in previous work
* ARM vst mangling needs to be conditional on opaque ptrs
The fixes from last week regarding mangling of arm vst intrinsics needs to be made conditional on whether the pointer is opaque or not; this will change based on whether `-D CLANG_ENABLE_OPAQUE_POINTERS=ON|OFF` is defined when LLVM is built, but should be sniffed via this API, according to my LLVM contact.
* Revert "ARM vst mangling needs to be conditional on opaque ptrs"
This reverts commit 9901314ff75dd0bf651b23d09c1d1f5f07d49ffd.

* Combine string constants in combine_strings() (#6717)
* Combine string constants in combine_strings()
This is a pretty trivial optimization, but when printing (or enabling `debug`), it cuts the number of `halide_string_to_string()` calls we generate by ~half.
* Update IROperator.cpp
* Update CodeGen_PTX_Dev to use new PassManager (#6718)
* Update CodeGen_PTX_Dev to use new PassManager
This was still using the LegacyPassManager for optimization, which will be going away at some point. (Code changes by @alinas; I'm just opening this PR on her behalf)
* Fixes after review
* Closure functions for parallel tasks should be internal, not external (#6720)
Minor optimization.
* Smarten type_of<> for fn ptrs; fix async_parallel for C backend (#6719)
* Smarten type_of<> for fn ptrs; fix async_parallel for C backend
(Fixes #2093)
This basically just adds the right type annotations to make the parallel code produced by the C backend compile properly. This could have been fixed by inserted some brute-force void* casting into the C backend, but this felt a lot cleaner.
The one thing here I'm a little unsure about is how I extended the Type code to be able to handle function-pointer types correctly; it works but doesn't feel very elegant.
* Update Makefile
* Update LowerParallelTasks.cpp
* FunctionTypedef
* Remove legacy::FunctionPassManager usage in Codegen_PTX_Dev (#6722)
LLVM devs indicate that none of the passes in this usage actually do anything and it can be safely removed.

I have *not* personally tested that these are detected correctly,

* Deprecate variadic-template version of Realization ctor (#6695)
* Deprecate variadic-template version of Realization ctor
The variadic-template approach was useful before C++11 (!) added brace initialization, but preferring an explicit vector-of-Buffer is arguably better, and provides better symmetry with the Python bindings.
Also, some drive-by tweaks to other Realization methods.
* Update PyPipeline.cpp

* Remove `rounding_halving_sub` and non-existent arm rhsub instructions (#6723)
* remove arm (s | u)rhsub instructions
* remove rounding_halving_sub intrinsic entirely
* Augment Halide::Func to allow for constraining Type and Dimensionality (#6734)
This enhances Func by allowing you to (optionally) constrain the type(s) of Exprs that the Func can contain, and/or the dimensionality of the Func. (Attempting to violate either of these will assert-fail.)
There are a few goals here:
- Enhanced code readability; in cases where a Func's values may not be obvious from the code flow, this can allow an in-code way of declaring it (rather than via comments)
- Enhanced type enforcement; specifying constraints allows us to fail in type-mismatched compilations somewhat sooner, with somewhat better error messages.
- Better symmetry for AOT/JIT code generation with ImageParam, in which the inputs (ImageParam) have a way to specify the required concrete type, but the outputs (Funcs) don't.
If this is accepted, then subsequent changes will likely add uses where it makes sense (e.g., the Func associated with an ImageParam should always have both type and dimensionality specified since it will always be well-known).
Note that this doesn't add any C++ template class for static declarations (e.g. `FuncT<float, 2>` -> `Func(Float(32), 2)`); these could be added later if desired.
* More typed-Func work (#6735)
- Allow Func output_type(s)(), outputs(), dimensions(), and output_buffer(s)() to be called on undefined Funcs if the Func has required_type and required_dimensions specified. This allows for greater flexibility in defining pipelines in which you may want to set or examine constraints on a Func that hasn't been defined yet; previously this required restructuring code or other awkwardness.
- Ensure that the Funcs that are defined for ImageParams and Generator fields define the types-and-dims when known.
- Add some tests.
* Add missing #include <functional> in ThreadPool.h (#6738)
* Add missing #include <function> in ThreadPool.h
* Update ThreadPool.h
* Fix regression from #6734 (#6739)
That change inadvertently required the RHS of an update stage that used `+=` (or similar operators) to match the LHS type, which should be required (implicit casting of the RHS is expected). Restructured to remove this, but still ensure that auto-injection of a pure definition matches the required types (if any), and updated tests.
* Add forwarding for the recently-added Func::output_type() method (#6741)
* Silence "unscheduled update stage" warnings in msan_generator.cpp (#6740)
* Add __pycache__ to toplevel .gitignore file (#6743)
* Revise PyStub calling convention for GeneratorParams (#6742)
This is a rethink of https://github.com/halide/Halide/pull/6661, trying to make it saner in anticipation of the ongoing Python Generator work.
TL;DR: instead of mixing GeneratorParams in with the rest of the keywords, segregate them into an optional `generator_params` keyword argument, which is a plain Python dict. This neatly solves a couple of problems:
- synthetic params with funky names aren't a problem anymore.
- error reporting is simpler because before an unknown keyword could have been intended to be a GP or an Input.
- GP values are now clear and distinct from Inputs, which is IMHO a good thing.
This is technically a breaking change, but I doubt anyone will notice; this is mainly here to get a sane convention in place for use with Python Generators as well.
Also, a drive-by change to Func::output_types() to fix the assertion error message.
* Silence "may be used uninitialized" in Buffer::for_each_element() (#6747)
In at least one version of GCC (Debian 11.2.0-16+build1), an optimized build using `Buffer::for_each_element(int *pos)` will give (incorrect) compiler warnings/errors that "pos may be used uninitialized).
From inspection of the code I feel pretty sure this is a false positive -- i.e., the optimizer is confused -- and since no other compiler we've encountered issues a similar warning (nor do we see actual misbehavior), I'm inclined not to worry -- but the warning does break some build configurations.
Rather than try to fight with selectively disabling this warning, I'm going to propose inserting a memset() here to reassure the compiler that the memory really is initialized; while it's unnnecessary, it's likely to be insignificant compared to the cost of usual calls to for_each_element().
(BTW, this is not a new issue, I've seen it for quite a while as this GCC is the default on one of my Linux machines... it just finally annoyed me enough to want to make it shut up.)
* Update WABT to 1.0.29 (#6748)
* Update hannk README link to hosted models page (#6749)
The current one is being sunsetted
* Add a `HalideError` base class to Python bindings (#6750)
* Add a `HalideError` base class to Python bindings
Per suggestion from @alexreinking, this remaps all exceptions thrown by the Halide Python bindings to be `halide.HalideError` (or a subclass thereof), rather than plain old `RuntimeError`.
* Remove scalpel left in patient
* Don't use a subclass for PyStub error handling
* Deprecate GeneratorContext getters with `get_` prefix (#6753)
Minor hygiene: most getters in Halide don't have a `get_` prefix. These are very rarely used (only one instance in our test suite I could find) but, hey, cleanliness.
* Add GeneratorFactoryProvider to generate_filter_main() (#6755)
* Add GeneratorFactoryProvider to generate_filter_main()
This provides hooks to allow overriding the Generator(s) that generate_filter_main() can use; normally it defaults to the global registry of C++ Generators, but this allows for (e.g.) alternate-language-bindings to selectively override this (e.g. to enumerate only Generators that are visible in that language, etc).
(No visible change in behavior from this PR; this is just cherry-picked from work-in-progress elsewhere to simplify review & merge)
* Update Generator.cpp
* Fix error handling
* Deprecate disable_llvm_loop_opt (#4113) (#6754)
This PR proposes to (finally) deprecate disable_llvm_loop_opt:
- make LLVM codegen default to no loop optimization; you must use enable_llvm_loop_opt explicitly to enable it
- disable_llvm_loop_opt still exists, but does nothing (except issue a user_warning that the feature is deprecated)
- Remove various uses of disable_llvm_loop_opt
- Add comments everywhere that the default is different in Halide 15 and that the disable_llvm_loop_opt feature will be removed entirely in Halide 16
Note that all Halide code at Google has defaulted to having disable_llvm_loop_opt set for ~years now, so this is a well-tested codepath, and consensus on the Issue seemed to be that this was a good move.
* Minor metadata-related cleanups (#6759)
(Harvested from #6757, which probably won't land)
- Add clarifying comment/reference in Generator
- Add assertion to compile_to_multitarget() function
- Fix misleading/wrong code in correctness_compile_to_multitarget
* Expand the x86 SIMD variants tested in correctness_vector_reductions (#6762)
A recent bug in LLVM codegen was missed because it only affected x86 architectures with earlier-than-AVX2 SIMD enabled; it didn't show up for AVX2 or later. This revamps correctness_vector_reductions to re-run multiple times when multiple SIMD architectures are available on x86 systems.
(correctness_vector_reductions was chosen here because it reliably demonstrated the specific failures in this case.)

* Fix fundamental confusion about target/tune CPU (#6765)
* Fix fundamental confusion about target/tune CPU
Sooo. Uh, remember when in https://github.com/halide/Halide/pull/6655
we've agreed that we want to add support to precisely specify
the CPU for which the code should be *tuned* for,
but not *targeted* for. Aka, similar to clang's `-mtune=` option,
that does not affect the ISA set selection?
So guess what, that's not what we did, apparently.
`CodeGen_LLVM::mcpu()` / `halide_mcpu` actually do specify
the *target* CPU. It was obvious in retrospect, because e.g.
`CodeGen_X86::mattrs()` does not, in fact, ever specify `+avx2`,
yet we get AVX2 :) So we've unintentionally added `-march=` support.
Oops.
While i'd like to add `-march=` support, that was not the goal here.
Fixing this is complicated by the fact that
`llvm::Target::createTargetMachine()` only takes `CPU Target` string,
you can't specify `CPU Tune`.
But this is actually a blessing in disguise,
because it allows us to fix another bug at the same time:
There is a problem with halide "compile to llvm ir assembly",
a lot of information from Halide Target is not //really// lowered
into LLVM Module, but is embedded as a metadata,
that is then extracted by halide `make_target_machine()`.
While that is not a problem in itself, it makes it *impossible*
to dump the LLVM IR, and manually play with it,
because e.g. the CPU [Target] and Attributes (ISA set)
are not actually lowered into the form LLVM understands,
but are in some halide-specific metadata.
So, to fix the first bug, we must lower the CPU Tune
into per-function `"tune-cpu"` metadata,
and while there we might as well lower `"target-cpu"`
and `"target-features"` similarly.
* Address review notes
* Hopefully silence bogus issue reported by ancient GCC
* Call `set_function_attributes_from_halide_target_options()` when JIT compiling
* Fix grammar
* Fix annoying typo in Func.h (#6774)
Update Func.h
* Add execute_generator() API (#6771)
This refactors the existing `generate_filter_main()` call in two, moving the interesting implementation of how to drive AOT into the new `execute_generator()` call (reducing `generate_filter_main()` to parsing argc/argv and error reporting).
The new `execute_generator()` is intended to be used (eventually) from Python, as a way to drive Generator compilation from a Python script more easily. The PR doesn't provide a Python wrapper for this call yet (that will come in a subsequent PR).
Also, a drive-by removal of the "error_output" arg to generate_filter_main() -- AFAICT, no one has ever used it for anything but stderr, and the refactoring now just directs all errors to `user_error` uniformly.

* [miscompile] Don't de-negate and change direction of shifts-by-unsigned (#6782)
I'm afraid the problem is really obvious:
https://github.com/halide/Halide/blob/b5f024fa83b6f1cfe5e83a459c9378b7c5bf096d/src/CodeGen_LLVM.cpp#L2628-L2649
^ the shift direction is treated as flippable by the codegen
iff the shift amount is signed :)
The newly-added test fails without the fix.
I've hit this when writing tests for https://github.com/halide/Halide/pull/6775
* Move some options from execute_generator back to generate_filter_main (#6787)
Loading plugins and setting the default autoscheduler name both change global state, which isn't a desirable fit for execute_generator(), since it's not intended to mutate global state. (Mutating the state from a main() function is of course a reasonable thing to do.)
* LLVM codegen: register AA pipeline if LLVM is older than 14 (#6785)
It's the default after https://reviews.llvm.org/D113210 / https://github.com/llvm/llvm-project/commit/13317286f8298eb3bafa9ddebd1c03bef4918948,
but still needs to be done for earlier LLVM's.

* slow tests should support sharding
The simd_op_check test suite is pretty slow (especially for wasm, where it is interpreted); at one point we tried to use ThreadPool to speed it up, but too many pieces of Halide IR aren't threadsafe and we disabled it long ago.
This removes the ThreadPool usage entirely, and instead adds support for the GoogleTest 'sharded test' protocol, which uses certain env vars to allow a test to opt in for splitting its test into smaller pieces.
At present our buildbot isn't attempting to make use of this feature, but it will be a big win for downstream usage in Google, where tests that run "too long" are problematic and splitting them into multiple shards makes various day to day activiites much more pleasant.

* Disable testing for apps/linear_algebra on x86-32-linux/Make
This wasn't biting us before because we were disabling *all* apps/ on x86-32-linux (oops); the recent change to remove python testing under Make also re-enabled this test.
TL;DR: this can probably be made to work somehow, but it's not worth debugging, since that case is both pretty nice, and already covered under CMake. It's literally not worth the time to fix.
* Update Makefile
* Rearrange subdirectories in python_bindings (#6835)
This is intended to facilitate a few things:
- Move all Generators used in tests, apps, etc to a single directory to simplify the build rules (this is especially useful for the work in https://github.com/halide/Halide/pull/6764)
- Put all the test and apps stuff under a single directory to facilitate adding some Python packaging that can make integration into Bazel/Blaze builds a bit less painful
@alexreinking, does this look like the layout we discussed before?
* Better lowering of halving_sub and rounding_halving_add (#6827)
* Better lowering of halving_sub and rounding_halving_add
Previously, lower_halving_sub and lower_rounding_halving_add both used 9
ops. This change redirects halving_sub to use rounding_halving_add, and
redirects rounding_halving_add to use halving_add. In the case that none
of these instructions exist natively, this reduces it to 7/8 ops for
signed/unsigned halving sub and 6 ops for rounding halving add.
More importantly, this lets halving_sub make use of pavgw/b on x86 to
reduce it to 3 ops for u8 and u16 inputs.
* Make signed rounding_halving_add on x86 use pavgb/w too
* Cast result back to signed

* Check RDom::where predicates for race conditions (#6842)

* Remove Generator::value_tracker and friends (#6845)
This is an internal-to-Generator helper that is used to try to detect certain classes of errors when using GeneratorStubs. To the best of my knowledge, it has ~never found a useful error in all of its existence; combined with the very limited usage of GeneratorStubs, I think this code no longer pays for itself, and should be removed.
(Note that this was never externally visible, thus no deprecation warnings should be necessary.)
* Deprecate/remove Generator::get_externs_map() and friends (#6844)
* Deprecate/remove Generator::get_externs_map() and friends
This is a feature of Generator that was added years ago to allow adding external code libraries in LLVM bitcode form (rather than simply as extern "C" or similar). In theory it allow for better codegen for external code modules (since LLVM has access to all the bitcode for optimization); in practice, we only know of one project that ever used it, and that project no longer exists. Additionally, it tended to be fairly flaky in terms of actual use -- e.g., missing symbols tended to crop up unpredictably.
The issues with this feature are likely fixable, but since it hasn't (AFAICT) been used in ~years, we're better off deprecating it for Halide 15 and removing for Halide 16.
(If anyone out there is still relying on this feature, obviously you should speak up ASAP.)

As discussed in https://github.com/halide/Halide/issues/6801#issuecomment-1152731683
I don't think this is complete, there are likely a few more places
that need to be taught about it still, altough i think this is mostly it.
Note that this only promotes the intrinsic,
this does not adjust it's handling, as hinted in:

1. LLVM IR `bitcast` happily bitcasts between vectors and scalars: https://godbolt.org/z/9zqx11rna
2. `ptrtoint` already implicitly truncates/zero-extends if the int is larger than the pointer type: https://llvm.org/docs/LangRef.html#ptrtoint-to-instruction
3. `inttoptr` already implicitly truncates/zero-extends if the int is larger than the pointer type: https://llvm.org/docs/LangRef.html#inttoptr-to-instruction
So we don't need to do any of that 'special' handling.
* [Codegen] Fail to codegen `Call::undef`, just like `Call::signed_integer_overflow` (#6871)
See discussion in https://github.com/halide/Halide/pull/6866.
It's not obvious if that codepath is ever hit,
let's optimistically assume that it is not.
If this turns out to be not true, we'll have to deal with
a more complicated question of the proper lowering for it,
can it be `poison`, or must it be a `freeze poison`.

* [Codegen_LLVM] Define all the things (#6866)
Long-term plan for LLVM is to get rid of `undef`,
and replace it with zero-initialization,
err, `poison`, because it has nicer semantics.
Everywhere we use `undef` as a placeholder in shuffle
(be it either for a second operand, or undef shuffle mask element),
or as a base 'empty' vector we are about to fully override
via insertelement, we can just switch those to poison nowadays.
The scary part is the `Call::undef` semantics/lowering,
perhaps it will need to be `freeze poison`.
* Add set-host-dirty/copy-to-host to PythonExtensionGen (#6869)
* Add set-host-dirty/copy-to-host to PythonExtensionGen
See https://github.com/halide/Halide/issues/6868: Python Buffers are host-memory-only, so if the AOT-compiled halide code runs on (say) GPU, it may fail to copy the inputs to device and/or the results back to host. This fixes that. (We still need a solution that allows for lazy copies, but that will require adding another protocol that supports it.)
* Update PythonExtensionGen.cpp
* Rewrite PythonExtensionGen to be C++ based (#6888)
* Rewrite PythonExtensionGen to be C++ based
This is intended as an alternative to #6885 -- this is even *more* gratuitous, but:
- We have ~always compiled Python extensions using C++ anyway
- This code is arguably terser, cleaner, and safer (the cleanups happen via dtors)
- The code size difference is negligible (~300 bytes out of 160k for addconstant.cpython-39-darwin.so)

* Add `auto_schedule` label to Adams2019 and Li2018 tests in CMake
These were ~never getting tested on the buildbots (and still aren't, I need to update it to run `auto_schedule` tests) but conceptually these tests should be in the same group as for Mullapudi.

* [Simplify] Drop no-op single-input identity shuffles (#6901)
* [Codegen_LLVM] Annotate LLVM IR functions with `nounwind`/`mustprogress` attributes (#6897)
My reasoning is as follows, please correct me if i'm wrong:
1. Halide-generated code never throws exceptions
2. Halide-generated code always `call`s (as opposed to `invoke`s) the functions, there is no exception-safety RAII
3. Halide loops are meant to have finite number of iterations, they aren't meant to be endless and side-effect free
4. Halide (IR) assertions *might* abort.
5. Likewise, external callees *might* abort. (???)
Therefore, when not in presence of external calls,
it is obvious that (1) no exception will be unwinded
out of the halide-generated function, (2) none of the loops
will end up being endless with no observable side-effects.
... which is the semantics that is being stated by the
LLVM IR function attributes `nounwind`+`mustprogress`.
I'm less clear as to what are the prerequisites on the behavior of
the external callees, but i do believe that they must also
at least not unwind. I guess they are also at least required to
either return or abort eventually.

* Fix broken Makefile rules for autoschedulers on OSX (#6906)
* Fix broken Makefile rules for autoschedulers on OSX
A few issues here:
- Make was building the plugins as .dylib on OSX, but they should have been .so to match Linux (and just on general principles)
- On OSX, explicitly linking libHalide.dylib into a plugin means that it will load its own copy of libHalide, which is bad, because it means the plugin doesn't share the same set of globals. We need to omit that explicit dependency and allow it to just find the exported symbols at load time.
- Add a test to verify the fix; run it everywhere even though it should only have been failing for Make-build OSX builds.
Finally, let me add that we really need to set a sunset date for supporting Make in Halide. The Makefiles aren't really maintained properly anymore, and when something subtle goes wrong, it takes an unreasonable amount of time to debug for something that is no longer our canonical build tool.

* Halide::Error should not extend std::runtime_error
Unfortunately, the std error/exception classes aren't marked for DLLEXPORT under MSVC; we need our Error classes to be DLLEXPORT for libHalide (and python bindings). The current situation basically causes MSVC to generator another version of `std::runtime_error` marked for DLLEXPORT, which can lead to ODR violations, which are bad. AFAICT we don't really rely on this inheritance anywhere, so this just eliminates the inheritance entirely.
(Note that I can't point to a specific malfunction resulting from this, but casual googling based on the many warnings MSVC emits about the current situation has me convinced that it needs addressing.)
