e3e169d | Steven Johnson | 27 July 2022, 16:21:44 UTC | 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) * Update PythonExtensionGen.cpp | 27 July 2022, 16:21:44 UTC |
7821212 | Steven Johnson | 25 July 2022, 16:32:24 UTC | 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 | 25 July 2022, 16:32:24 UTC |
5e69ad9 | Roman Lebedev | 25 July 2022, 16:24:56 UTC | [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`. | 25 July 2022, 16:24:56 UTC |
11a049c | Derek Gerstmann | 22 July 2022, 22:20:47 UTC | #6863 - Fixes to make address sanitizer happy for internal runtime classes (#6880) * Fixes to make address sanitizer happy.

06fcf94 | Steven Johnson | 21 July 2022, 19:14:39 UTC | Fix error in Makefile for Adams2019 on OSX (#6877) We erroneously link in the dylib and also dynamically load it, causing an error. We should skip the linkage and always load dynamically.. | 21 July 2022, 19:14:39 UTC |
04c465b | Roman Lebedev | 21 July 2022, 19:11:22 UTC | [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`. | 21 July 2022, 19:11:22 UTC |
8b5486b | Roman Lebedev | 21 July 2022, 16:35:40 UTC | [Codegen_LLVM] Radically simplify `visit(const Reinterpret *op)` (#6865) 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. | 21 July 2022, 16:35:40 UTC |

359026a | Roman Lebedev | 20 July 2022, 00:19:44 UTC | Promote Reinterpret Intrinsic into an Reinterpret IR Node (#6853) * Promote Reinterpret Intrinsic into an Reinterpret IR Node 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.

708a320 | Steven Johnson | 11 July 2022, 23:27:49 UTC | 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.) * Also remove ExternalCode.h & friends * Also remove correctness/external_code.cpp * HALIDE_ALLOW_GENERATOR_EXTERNS_MAP -> HALIDE_ALLOW_GENERATOR_EXTERNAL_CODE | 11 July 2022, 23:27:49 UTC |
d266e4e | Steven Johnson | 11 July 2022, 22:07:54 UTC | 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.) | 11 July 2022, 22:07:54 UTC |
8159dd3 | Alex Reinking | 11 July 2022, 18:39:14 UTC | Check RDom::where predicates for race conditions (#6842) Fixes #6808 | 11 July 2022, 18:39:14 UTC |
29ebde9 | Andrew Adams | 11 July 2022, 18:03:55 UTC | 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 * Add explanatory comment * Fix comment * Add explanation of signed case | 11 July 2022, 18:03:55 UTC |
23c4cf1 | Steven Johnson | 01 July 2022, 17:10:34 UTC | 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? | 01 July 2022, 17:10:34 UTC |

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.

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. | 23 May 2022, 18:31:03 UTC |

b5f024f | Roman Lebedev | 19 May 2022, 17:10:53 UTC | 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 | 19 May 2022, 17:10:53 UTC |

c8531a5 | Steven Johnson | 05 May 2022, 01:17:40 UTC | 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.) | 05 May 2022, 01:17:40 UTC |
1606039 | Steven Johnson | 04 May 2022, 00:16:26 UTC | 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.

799c546 | Steven Johnson | 27 April 2022, 20:48:27 UTC | 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. | 27 April 2022, 20:48:27 UTC |

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 | 20 April 2022, 17:01:39 UTC |
