e038765 Steven Johnson 18 April 2022, 18:20:51 UTC Codegen_C: check the result of snprintf() Technically, we should check the return code of sprintf() for failure conditions. This is a minimal fix designed to quietly ensure that encoding errors aren't overlooked. (Since our "C" output actually requires C++11 at this point, I was tempted to replace it with `ostringstream`, but decided to avoid bringing that in...) 18 April 2022, 18:20:51 UTC
60a909f Steven Johnson 14 April 2022, 16:49:38 UTC Fix type-mangling for vst on arm32 for LLVM15 (#6705) 14 April 2022, 16:49:38 UTC
77f7f5e Steven Johnson 13 April 2022, 21:31:17 UTC 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 13 April 2022, 21:31:17 UTC
87c0cc9 Andrew Adams 12 April 2022, 23:38:56 UTC llvm no longer wants a type suffix on vst intrinsics (#6701) * llvm no longer wants a type suffix on vst intrinsics * Fix silly mistake * Change 64-bit only Co-authored-by: Andrew Adams <anadams@adobe.com> 12 April 2022, 23:38:56 UTC
3d7b977 Steven Johnson 12 April 2022, 23:33:02 UTC Drop support for Matlab extensions (#6696) * Drop support for Matlab extensions Anecdotally, this hasn't been used in ~years, and the original author (@dsharletg) had suggested dropping it a while back. I'm going to propose we go ahead and drop it for Halide 15 and see who complains. * Fixes for top-of-tree LLVM * Update force_include_types.cpp * trigger buildbots * Update CodeGen_LLVM.cpp 12 April 2022, 23:33:02 UTC

f906eba Steven Johnson 11 April 2022, 16:47:39 UTC Silence "unknown warning" in Clang 13 (#6693) Clang 13 removed the `return-std-move-in-c++11` warning entirely, so specifying it now warns that the warning is unknown. 11 April 2022, 16:47:39 UTC

887d340 Steven Johnson 08 April 2022, 19:01:27 UTC 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) 08 April 2022, 19:01:27 UTC
b5840f7 Steven Johnson 08 April 2022, 00:59:14 UTC Drop support for LLVM12 (#6686) * Drop support for LLVM12 Halide 15 only needs to support LLVM13 and LLVM13.

9866df2 Steven Johnson 05 April 2022, 23:23:25 UTC 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. 05 April 2022, 23:23:25 UTC

6b9ed2a Steven Johnson 30 March 2022, 22:30:42 UTC Remove the nobuild/partialbuildmethod tests from python_bindings/ (#6668) They no longer serve a purpose and are redundant to other tests. 30 March 2022, 22:30:42 UTC
5d2abd3 Steven Johnson 29 March 2022, 23:33:42 UTC Add ldscript code for Python extensions in CMake (#6665) * Add ldscript code for Python extensions in CMake We added ldscripts to the Makefile for Python extensions (to restrict exported symbols to just the PyInit_foo symbol), but neglected to do so for CMake. This corrects that. 29 March 2022, 23:33:42 UTC
8aba364 Steven Johnson 29 March 2022, 18:56:33 UTC Allow `make test_apps` to work with ASAN (#6659) * Allow `make test_apps` to work with ASAN With asan or tsan in the target, there is a space in the OPTIMIZE var, so it needs to be quoted. * tickle buildbots * tickle buildbots * tickle buildbots 29 March 2022, 18:56:33 UTC
ed3f4a7 Steven Johnson 29 March 2022, 00:10:49 UTC Add optional runtime H::R::Buffer access checks (#6660) * Add optional runtime H::R::Buffer access checks This adds some optional `assert()` checks to HRB's `operator()` and friends. They are only enabled if `HALIDE_RUNTIME_BUFFER_CHECK_INDICES=1` is defined at compile time. Also fixes errors found by enabling these assertions and running tests. * Update fast_pow.cpp * clang-format * tickle buildbots * tickle buildbots 29 March 2022, 00:10:49 UTC
c2bebe2 Steven Johnson 29 March 2022, 00:10:37 UTC Python Bindings: fix Python `bool` -> `Expr` implicit conversion (#6657) * Python Bindings: fix Python `bool` -> `Expr` implicit conversion It was implicitly converting to a Halide `Int(32)` literal of value 1, but we want it to match Halide's boolean type of `UInt(1)` * Update basics.py * wip * tickle buildbots 29 March 2022, 00:10:37 UTC
14d89f3 Steven Johnson 25 March 2022, 23:38:46 UTC Fix 'variable set but not used` warning/error (#6658) Yes, some compilers complain about this. 25 March 2022, 23:38:46 UTC
17b537c Zalman Stern 22 March 2022, 19:04:53 UTC Timer based profiler (#6642) * Add support for timer interrupt based profiling, which is useful for bring up on embedded ("bare metal") systems that may not have a full OS with threads. * Update runtime_api file with new routines. * Turn locking back on in timer based profiling case as it can be used in multiprocessor situations. (Both as an option on systems where threads would be fine and on embedded systems which don't have time shared threads but cores are dedicated to the Halide threadpool.) * Add target flag for timer profiling and extend performance_profiler test to cover timer profiling. 22 March 2022, 19:04:53 UTC

07dddb7 Steven Johnson 10 March 2022, 18:57:29 UTC Allow profiler feature under wasm iff wasm_threads is enabled (#6643) The profiler requires threads, but works fine when wasm_threads are enabled. 10 March 2022, 18:57:29 UTC
f6628aa Steven Johnson 10 March 2022, 18:50:25 UTC Fix UB in hannk FillWithRandom operation. (#6645) A recent change to libc++ rejects std::uniform_int_distribution<uint8_t> explicitly (https://reviews.llvm.org/D114920). This change prevents this file to build with upcoming revisions of the C++ toolchain. 10 March 2022, 18:50:25 UTC
105f7e5 Steven Johnson 07 March 2022, 20:59:04 UTC Fix const-correctness in C/C++ backend (Issue #6636) (#6638) in the Load handler, we need to emit the cast in the form `TYPE const *` rather than `const TYPE *`, as TYPE could be `void *`, and the const would bind in a way we don't want. 07 March 2022, 20:59:04 UTC
5f37d50 Steven Johnson 07 March 2022, 20:58:12 UTC Convert most remaining Generators to prefer statically-dimensioned Inputs and Output where possible (#6641) This is the same as #6620, except that it omits autoschedulers/adams2019/cost_model_generator.cpp (which is unusually complex and not yet settled as to whether the changes are welcome). Basically an attempt to land the uncontroversial parts. 07 March 2022, 20:58:12 UTC
a55ae55 Alexander Root 06 March 2022, 20:21:32 UTC Clear bounds info on casts when value bounds are undefined (for overflow types) (#6640) 06 March 2022, 20:21:32 UTC

Cleaned up. Also vastly reduced build-time noise. * Update Makefile * Add linker scripts for Python extensions 06 March 2022, 00:24:29 UTC
3827279 Steven Johnson 04 March 2022, 00:49:18 UTC Python Bindings didn't allow for zero-D Funcs, ImageParams, Buffers (#6633) * Python Bindings didn't allow for zero-D Funcs, ImageParams, Buffers There were no overloads or tests for accessing the element of any of these in the zero-D case, and the obvious syntax (`[]`, to mirror C++ `()` in these cases) isn't legal in Python. To support this uncommon-but-necessary case, I'm proposing that we use the syntax `[None]`, which isn't pretty, but is less bad than other options I've considered so far. (Suggestions welcome.) * Use [()] instead of [None] 04 March 2022, 00:49:18 UTC
86728d7 Alexander Root 26 February 2022, 18:56:09 UTC Wild match object is not foldable (#6623) 26 February 2022, 18:56:09 UTC

6424aaa Andrew Adams 01 February 2022, 22:24:11 UTC Reenable warning about unscheduled update definitions and fix associated issues in the tests and apps. This is an old warning that stopped triggering because it wasn't tested. We should either remove it, fix the trigger conditions, or perhaps make it an error. This PR fixes the trigger conditions and fixes all instances of the warning in our tests and apps. The warning triggers if you schedule some but not all of the update definitions of a Func. It's to protect against the common error of only scheduling the pure definition of something like a summation. The warning can be suppressed by inserting a call to func.update(idx). 18 February 2022, 22:26:15 UTC

38032e8 Basile Clement 14 February 2022, 18:43:50 UTC Only commutative reductions can be parallelized (#6609) Because parallelization changes the order of computation within the reduction, parallelizing associative but non-commutative reductions can result in (non-deterministically) incorrect results in the same way `reorder`ing them can. For instance Halide currently accepts the following code, but generates non-deterministic outputs on GPU. On CPU with `.parallel(r.x)`, OpenMP rejects the generated code (correctly) stating that the `#pragma omp atomic` is invalid for the same reasons. ```c++ #include <stdio.h> #include "Halide.h" using namespace Halide; int main(int argc, char **argv) { Halide::Func A("A"), B("B"); Halide::Var i("i"); A(i) = i; B() = -1; Halide::RDom r(0, 1024); B() = A(r.x); A.compute_root(); B.update().atomic().gpu_blocks(r.x); B.compile_jit(get_host_target().with_feature(Target::CUDA)); Halide::Buffer<int32_t> b = B.realize(); printf("%d\n", b()); return 0; } ``` 14 February 2022, 18:43:50 UTC
832efeb Steven Johnson 11 February 2022, 22:46:23 UTC Update WasmExecutor for WABT API changes (#6612) * Update WasmExecutor for WABT API changes The API for WABT has changed in top-of-tree. This fixes the incompatibilities. It also (temporarily) changes to pulling WABT from top-of-tree (rather than a known release) as the most recent labeled release doesn't have these changes. (We'll change back to a fixed WABT release when the next one is released.) * Update CMakeLists.txt 11 February 2022, 22:46:23 UTC
dd32beb Zalman Stern 11 February 2022, 15:53:50 UTC Fixes to support LLVM with opaque pointers. (#6608) Removes uses of LLVM API routines that recover pointed to types from LLVM pointer types as that functionality is going away with opaque pointers. 11 February 2022, 15:53:50 UTC

2008f7c Steven Johnson 25 January 2022, 22:08:50 UTC Fix Win32-specific breakage in top-of-tree LLVM (#6581) (Second attempt at this; first version was landed and rolled back because the LLVM change was rolled back) 25 January 2022, 22:08:50 UTC
5f0da26 Steven Johnson 25 January 2022, 20:47:48 UTC Add support for wasm-simd ops for integer-integer widening (#6567) * Add simd-extend support * Update simd_op_check.cpp * clang-format * Update CodeGen_WebAssembly.cpp 25 January 2022, 20:47:48 UTC
4030a55 Andrew Adams 25 January 2022, 20:21:56 UTC Rename Output to OutputFileType and deprecated Output (#6568) * Rename Output to OutputFile and deprecated Output It would be nice in future if we could promote Generator::Input and Generator::Output to the Halide namespace. For that to happen, we need to rename the enum Output first. This adds a new name for it, and deprecates the old name. * OutputFile -> OutputType Also fix python bindings and use the right deprecation macro * OutputType -> OutputFileType * clang-format * Update python tutorials and tests 25 January 2022, 20:21:56 UTC

6a63609 Steven Johnson 21 January 2022, 23:20:41 UTC Allow calling scheduling methods on Output<Buffer[]> (#6577) The constness of the inherited operator[] meant you couldn't call scheduling methods on array-of-output-buffer in a Generator. Fixed and added a test case. 21 January 2022, 23:20:41 UTC

030fe5a Steven Johnson 18 January 2022, 21:23:49 UTC wasm simd cleanup (#6566) - f64x2.convert_low_i32x4_s/u is handled properly by LLVM 14, so remove the TODO stuff and leave the test special-cased for that version (don't bother trying to make it work in LLVM13) - our `float_to_double` glue is only needed for LLVM13, so update comments and ifdefs appropriately 18 January 2022, 21:23:49 UTC

1aa68fb Steven Johnson 16 January 2022, 20:58:36 UTC Enable simd_op_check test for wasm i8x16.popcnt (#6562) LLVM does in fact generate this correctly, but only for 8x16 sized vectors 16 January 2022, 20:58:36 UTC
e581669 Andrew Adams 14 January 2022, 17:48:42 UTC Make HALIDE_REGISTER_GENERATOR work with multiple template args (#6556) * Make HALIDE_REGISTER_GENERATOR work with multiple template args * Add missing generator to cmakefile * Can't put parens around this usage * Another attempt at stripping parens from a type Co-authored-by: Steven Johnson <srj@google.com> 14 January 2022, 17:48:42 UTC

b9e0e72 Steven Johnson 13 January 2022, 04:35:23 UTC Use add_halide_generator() everywhere in apps/ (#6554) * Use add_halide_generator() everywhere in apps/ Existing CMake code uses add_executable + target_link_libraries to create a Generator, but the somewhat-recently-added add_halide_generator() helper is a cleaner way to do this. Move to using it everywhere in apps/ instead. (Note that add_halide_generator()) doesn't yet work for in-tree builds, unfortunately.) * fixes * fully-qualify names * Update CMakeLists.txt * Fully Qualify * LINK_LIBRARIES * make add_halide_library() do some guessing * Update HalideGeneratorHelpers.cmake 13 January 2022, 04:35:23 UTC

bc5b557 Andrew Adams 09 January 2022, 02:55:57 UTC Better default lowering of absd (#6545) * Better default lowering of absd This produces 3 instructions on x86, whereas the previous version produced 5. * Switch to an x86-only solution * Fixes * Another fix. Add reference. * typo 09 January 2022, 02:55:57 UTC
4ec870d Dillon Sharlet 07 January 2022, 22:03:34 UTC Fix description of rounding_shift_left/rounding_shift_right (#6549) 07 January 2022, 22:03:34 UTC
b8a711a Andrew Adams 07 January 2022, 18:57:42 UTC Attempted redo of faster noise (#6539) * Make random 2x faster by putting the innermost var last * Improve period of low bits of random noise * Add new rewrite rules for quadratics By pulling constant additions outside of quadratics, we can shave off a few add instructions in the inner loop for random number generation, which uses a quadratic modulo 2^32 I also removed the !overflows predicates, because rules already fail to match if a fold overflows. New rules formally verified. * Make expensive_zero actually always zero * Partially revert new simplifier rules * Enable new rules * Revert test Co-authored-by: Steven Johnson <srj@google.com> 07 January 2022, 18:57:42 UTC
daa5b7c Steven Johnson 06 January 2022, 18:05:15 UTC Convert apps/hannk/Elementwise to use generate() (#6543) It's the only Generator in Halide that uses build() instead of generate() (aside from tests designed specifically to test build()); convert it to keep things nice and consistent. 06 January 2022, 18:05:15 UTC
