7108864 | Steven Johnson | 15 February 2023, 19:47:43 UTC | Remove ParamMap (Fix #7121) This PR proposes to remove ParamMap entirely for Halide 16; it was added to provide a threadsafe way to provide parameteres to the JIT, but `compile_to_callable()` now does this in a much less intrusive way. Normally I'd propose deprecating something like this first (eg via ifdef), but in this case it would be extremely intrusive to do so, so this PR just rips off the band-aid and removes it entirely -- feedback welcome on this. | 15 February 2023, 19:47:43 UTC |

e5ed226 | Steven Johnson | 15 February 2023, 17:03:41 UTC | Fix Python error handling (#7352) * Fix Python error handling Error handling in the Python bindings wasn't quite right for JIT: We previously replaced halide_error() to throw a C++ exception. Sounds good, but unfortunately, doesn't work reliably: if called from jitted code (which doesn't know about C++ exceptions), the throw statement may be unable to find the enclosing try block (which is outside jitted code), meaning it will call std::terminate. Now, instead, we just leave the JIT error handler unset, and call with an explicit JITUserContext with a custom print handler; in theory, this meant that the code in JITFuncCallContext::finalize() would check for an error after the call into jitted code, and call `halide_runtime_error` if so (which would then trigger an all-in-C++-exception). Unfortunately... (2) JITFuncCallContext is broken by design; it mutates the input JITUserContext, so that trying to use the same JITUserContext for two calls in a row leaves you with a JITUserContext with (at least) the error_handler set. Since at least one of the realize() calls does this twice (once for bounds query, once for execution), this means that an error in the second call would never be seen, since finalize() only reported errors if there wasn't a custom error handler on input. Per @abadams suggestion, we work around this by treating 'JITErrorBuffer::handler' as 'no custom error handler', which is mostly true. (But really, JITFuncCallContext and JITUserContext are a hard-to-reason-about mess and arguably need to rethought entirely.) (3) Removed entirely-unnecessary overrides of runtime print and error handlers from PyStubImpl; despite the comments, this code is unnecessary. * format | 15 February 2023, 17:03:41 UTC |
7963cd4 | Steven Johnson | 14 February 2023, 17:14:05 UTC | Change early-bound default args in Python bindings to late-bound (#7347) In PyBind11, if you specify a default argument for a method, it is evaluated when the Python module is initialized, *not* when the method is called (as you might expect in C++). For defaults that are just constants/literals, this is no big deal, but when calling get_*_target_from_environment, this means it is called at module init time -- also normally not a big deal (since the values ~never change at runtime anyway), with one big exception (no pun intended): if the function throws an exception (e.g. via calling user_assert() or similar), that exception is thrown at Module-initialization time, which is a much more inscrutable crash, and one that is very hard to recover from. This may seem unlikely, but can happen pretty easily if you set (say) HL_JIT_TARGET=host-cuda (or other gpu) and the given GPU runtime isn't present on the given system; the current behavior is basically "make if impossible for the libHalidePython bindings to run", whereas what we want is "runtime exception thrown when you call the method". This changes the relevant methods to use `Target()` as the default value, and inside the method wrapper, if the value passed equals `Target()`, it replaces the value with the righ `get_*_target_from_environment()` call. (This turned up while doing some testing of https://github.com/halide/Halide/pull/6924 on a system without Vulkan available) | 14 February 2023, 17:14:05 UTC |

6c5ca8e | Steven Johnson | 11 February 2023, 00:34:41 UTC | Tiny improvements in codegen in C backend (#7337) * Tiny improvements in codegen in C backend (1) Emit `true` or `false` instead of `(bool)(0ull)` etc for bool literals (2) Avoid redundant temporaries in print_cast_expr(), which occur in a small but nonzero number of cases Basically this means that code currently like ``` bool _523 = (bool)(0ull); bool _524 = (bool)(_523); ... foo(_524); ``` becomes ``` foo(false); ``` ...I'm sure this has no output on final object code, but it makes the generated C code less weird to read. * Also avoid extra intermediates for typed nullptr * Also use std::isnan() and std::isinf() * Update CodeGen_C.cpp | 11 February 2023, 00:34:41 UTC |
a6c5be7 | Steven Johnson | 10 February 2023, 21:28:51 UTC | Add a hook to Codegen_C::compile() (#7335) At least one subclass of Codegen_C currently has to replicate ~all of the compile(LoweredFunc) method, with the result that it has often gone stale (and still is stale) wrt changes in the base; this adds an optional method to allow some modifications to the function body just before it is printed, to avoid redundant code. | 10 February 2023, 21:28:51 UTC |

35322c3 | Steven Johnson | 10 February 2023, 00:22:10 UTC | Fix a subtle uninitialized-memory-read in Buffer::for_each_value() (#7330) * Fix a subtle uninitialized-memory-read in Buffer::for_each_value() When we flattened dimensions in for_each_value_prep(), we would copy from one past the end, meaning the last element contained uninitialized garbage. (This wasn't noticed as an out-of-bounds read because we overallocated in structure in for_each_value_impl()). This garbage stride was later used to advance ptrs in for_each_value_helper()... but only on the final iteration, so even if the ptr was wrong, it didn't matter, as the ptr was never used again. Under certain MSAN configurations, though, the read would be (correctly) flagged as uninitialized. This fixes the MSAN bug, and also (slightly) improves the efficiency by returning the post-flattened number of dimensions, potentially reducing the number of iterations f for_each_value_helper() needed. * Oopsie * Update HalideBuffer.h * Update HalideBuffer.h | 10 February 2023, 00:22:10 UTC |

Since it's legal via spec for `malloc(0)` to return nullptr, we need to be cautious here: if we are compiling with assertions enabled, *and* have a malloc() (etc) implementation that returns nullptr for alloc(0), we need to skip the assertion check, since we know the result won't be used.

This PR also adds the requirement that the memory returned must be legal to access in an integral multple of alignment >= the requested size (in other words: you should be able to do vector load/stores "off the end" without causing any faults). * Currently, the `halide_malloc_alignment()` function is used to determine the default alignment; this cannot be overridden by user code (well, it can be, but the override will have no useful effect). It is intended to be "internal only" but is used in at least one place outside the runtime (apps/hannk). This change removes the call entirely, in favor of a call that is harder to access from outside the runtime and much less likely for end users to attempt to call.

This change completely disconnects these tests from HL_TARGET; instead, each test now tests for a range of targets appropriate to the architecture being tested.

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 |
