| 73c61c3 | Steven Johnson | 28 November 2022, 21:52:51 UTC | Add optional "function_info" header output (#7170) Add optional "function_info" header output At first glance, this looks like a subset of what is already provided by the `_metadata()` functionality: describing the argument attributes of an AOT-generated Halide function. However, _metadata() is suboptimal for some use cases: Because it's expressed as ordinary data, we can only process it at runtime; the new fuctionality is expressed as a `constexpr` data structure, meaning we can process it at *compile* time if we so choose. (This is quite useful for producing automatic call wrappers, etc). At first I considered adding this to the normal `.h` file, but moving it into a new file is cleaner in a few ways: - It maintains the 'C-only' nature of the existing .h files (adding this would have imposed a C++17-only section on them) - Splitting into a new file means no existing users are affected by this change at all Note also that this is deliberately not replicating all of the existing `_metadata()` functionality (it's just the argument signature, but no e.g. estimates or default values, etc). This approach means that it is probably more sensible to add several separate constexpr "getters" to this file, rather than trying to mash everything together into one clumsy structure. (With _metadata(), there was an incentive to keep the surface area of the API small, even if that meant combining somewhat-unrelated concerns; there is no such incentive here.) | 28 November 2022, 21:52:51 UTC |

| 2f1587e | Steven Johnson | 28 October 2022, 00:18:41 UTC | Fix Python buffer handling (#7125) * Fix Python buffer handling In the category of "how did this ever work"... TL;DR: in general, Halide Buffers have the opposite axis ordering from Python/NumPy buffers; in Halide, the most-frequently-varying dimension comes first, while in Python, it comes last. This isn't surprising, though, since Halide's indexing scheme is effectively column-major while NumPy's is row-major. Anyway: what we *should* have done was to reverse the order of dimensions when converting to/from Halide Buffers vs Python buffers; instead, we kept the same order, then jumped thru hoops to rearrange buffers to fit this setup. This PR does the appropriate axis reordering, fixing the apps and tests as needed. It also adds some helper code for image reading and writing; by default, we use `imageio` for this, but imageio ~always wants RGB/RGBA images to be interleaved (vs the planar that Halide prefers). So, I added the `halide.imageio` package, that has wrapper functions to quietly convert to/from planar as needed. Needless to say, this change is likely to break existing code that is using 3d buffers in Halide, but I think it's the right long-term thing to do. Opinions greatly welcomed here. * Update PyBuffer.cpp * -"for better vectorization" * public halide.imageio utilities should copy() buffers * PEP8 * Update imageio.py * Update imageio.py * add 'reverse_axes' options to Buffer conversions (#7127) * add 'reverse_axes' options to Buffer conversions | 28 October 2022, 00:18:41 UTC |

| 59353ab | Zalman Stern | 26 September 2022, 19:37:26 UTC | Allow CodeGen_LLVM::codegen_buffer_pointer to support vectors. (#7049) This is useful for scatter/gather in the vector predication intrinsics work. | 26 September 2022, 19:37:26 UTC |
| a817414 | Zalman Stern | 24 September 2022, 00:16:33 UTC | Allow call_intrin to call an LLVM intrinsic with void return type. (#7048) Have ```CodeGen_LLVM::get_vector_type``` return the void type if passed the void type as a scalar base. This makes it possible to call intrinsics returning void via ```CodeGenn_LLVM::call_intrin```. Should be very safe as currently this anything doing this would fail inside the routine. The change breaks the invariant that any thing returned from get_vector_type is a vector type, but propagating void for function return types is a pretty standard behavior and if this was not intended, it will very likely fail just outside this instead of having failed inside the use. I.e. very low chance of spurious errors from this. | 24 September 2022, 00:16:33 UTC |
| 6499ad1 | Zalman Stern | 23 September 2022, 22:58:27 UTC | Fix false positive use after free warning. (#7046) Latest clang is giving a use after free warning for printing a pointer value after it is freed. The compiler is not exactly wrong in that a pointer is being passed to something after it is freed, but the something is just printing the pointer's value for debugging purposes. Cast through an intptr_t to avoid the warning. | 23 September 2022, 22:58:27 UTC |

| 666b87d | Steven Johnson | 23 September 2022, 18:15:13 UTC | add_requirement() maintenance (#7045) * add_requirement() maintenance This PR started out as a quick fix to add Python bindings for the `add_requirements` methods on Pipeline and Generator (which were missing), but expanded a bit to fix other issues as well: - The implementation of `Generator::add_requirement` was subtly wrong, in that it only worked if you called the method after everything else in your `generate()` method. Now we accumulate requirements and insert them at the end, so you can call the method anywhere. - We had C++ methods that took both an explicit `vector<Expr>` and also a variadic-template version, but the former required a mutable vector... and fixing this to not require that ended up creating ambiguity about which overloaded call to use. Added an ugly enable_if thing to resolve this. (Side note #1: overloading methods to have both templated and non-templated versions with the same name is probably something to avoid in the future.) (Side note #2: we should probably thing more carefully about using variadic templates in our public API in the future; we currently use it pretty heavily, but it tends to be messy and hard to reason about IMHO.) * tidy * remove underscores | 23 September 2022, 18:15:13 UTC |

| 7286ec3 | Steven Johnson | 22 September 2022, 17:07:32 UTC | Fix PyExt error handling (#7042) The current PythonExtensionGen code attempts to provide verbose error (exception) messages by overriding halide_error and saving the message in a thread_local. This isn't safe or correct, however, and (in general) is wrong for any Halide code using multiple threads. #6994 proposes ways to mitigate this (and there are experiments in place to implement it), but unless/until those enhancements land, we can't leave the code in its current state. So: - Don't try to save the text at all. - Optionally log the text to stderr. - Just throw an exception with the numeric error code. This is suboptimal, but better than the existing usually-incorrect-message behavior. - Bonus: wrap both the error and print overloads with `PyGILState_Ensure()`, as we are supposed to, to ensure we don't die. | 22 September 2022, 17:07:32 UTC |
