2cc0468 Steve Suzuki 20 January 2023, 17:39:41 UTC Fix issue in add_halide_runtime in cross-compilation (#7284) * Fix issue in add_halide_runtime in cross-compilation add_halide_runtime() tries to build generator executable, but it fails if we are working with cross-compiler toolchain. By using existing generator set as "FROM", we can work around this. 20 January 2023, 17:39:41 UTC
d44e99d Steve Suzuki 20 January 2023, 13:12:30 UTC Fix error of add_halide_generator in cross-compilation (#7283) In case the project name is CamelCase, add_halide_generator() was not able to find the generator package, because CMake searches <name>Config.cmake or <lower-case-name>-config.cmake 20 January 2023, 13:12:30 UTC

c9f3602 Steven Johnson 19 January 2023, 23:48:26 UTC Remove the watchdog timer from generator_main(). It was intended to k… (#7295) Remove the watchdog timer from generator_main(). It was intended to kill pathologically slow builds, but in the environment it was added for (Google build servers), it ended up being redundant to existing mechanisms, and removing it allows us to remove a dependency on threading libraries in libHalide. 19 January 2023, 23:48:26 UTC
51a4f6c Steven Johnson 19 January 2023, 23:36:47 UTC Emit prototypes for destructor functions in C Backend (#7296) We gathered up the destructors, but only emitted the prototypes if there was at least one non-C++ function declaration needed -- so if you built with cpp_name_mangling enabled, you might omit the right prototype. Fixed and added the right flag to a Generator test to tickle this behavior. 19 January 2023, 23:36:47 UTC
e8e1481 Steven Johnson 18 January 2023, 21:56:14 UTC Drop support for MIPS (#7287) (#7289) * Drop support for MIPS (#7287) * Update Target.cpp 18 January 2023, 21:56:14 UTC
888c41c Steven Johnson 18 January 2023, 00:47:52 UTC Add CMake support for C++ backend in test/generator (#7274) * Add support for C++ backend in test/generator When the CMake rules were rewritten a while back, the support for building/testing generators with the C++ backend (instead of the standard LLVM, etc) got lost. This adds it back in. Also made some drive-by fixes to the Makefile to enable some tests there that work correctly now. Also made a drive-by fix in in Codegen_C to fix allocation nodes that were just wrappers around buffer_get_host -- this prevented the cleanup_on_error test from building with the C++ backend. 18 January 2023, 00:47:52 UTC
0d43318 Steven Johnson 10 January 2023, 19:23:58 UTC Optimize Module::compile() for some edge cases (#7269) * Optimize Module::compile() for some edge cases Avoid redundant `compile_to_buffer()` calls for output requests that can't possibly ever need them. * Avoid mutation 10 January 2023, 19:23:58 UTC
a8d88bb Steven Johnson 10 January 2023, 17:51:38 UTC Use ::aligned_alloc() instead of std::aligned_alloc() in HalideBuffer.h (#7268) 10 January 2023, 17:51:38 UTC
eea7696 Steven Johnson 09 January 2023, 17:58:04 UTC Update README_python.md (#7266) 09 January 2023, 17:58:04 UTC
c070bb8 Alina Sbirlea 06 January 2023, 00:00:34 UTC Update change following LLVM WASM change f841ad30d77eeb4c51663e68efefdb734c7a3d07 (#7264) * Update change following LLVM WASM change https://github.com/llvm/llvm-project/commit/f841ad30d77eeb4c51663e68efefdb734c7a3d07 * Update checks conditional on LLVM version. 06 January 2023, 00:00:34 UTC
4b74049 Andrew Adams 05 January 2023, 21:12:50 UTC Inline into extern function args during bounds inference (#7261) * Inline into extern function args during bounds inference Fixes #7260 * Run CSE once at the end * Actually recursively inline * clang-tidy * trigger buildbots * Make test invariant to the number of times the warning is printed as long as it's at least once Co-authored-by: Steven Johnson <srj@google.com> 05 January 2023, 21:12:50 UTC
04bb986 Steven Johnson 28 December 2022, 17:31:01 UTC Conditional allocations shouldn't fail for size=0 in C++ backend (#7255) (#7256) * Conditional allocations shouldn't fail for size=0 in C++ backend (#7255) Allocations can be conditional; if the condition evaluates to false, we end up calling `halide_malloc(0)` (or `halide_tcm_malloc(0)` in the xtensa branch). 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. Note: a similar check will be inserted in the xtensa branch separately. Note 2: LLVM backend already has this check via Codegen_Posix.cpp * Update CodeGen_C.cpp 28 December 2022, 17:31:01 UTC
ade8b56 Steven Johnson 20 December 2022, 20:05:19 UTC Remove deprecated halide_target_feature_disable_llvm_loop_opt (#7247) * Remove deprecated halide_target_feature_disable_llvm_loop_opt Was deprecated in Halide 15; let's remove in Halide 16 * trigger buildbots * trigger buildbots * Update CodeGen_LLVM.cpp 20 December 2022, 20:05:19 UTC
10345d4 Andrew Adams 16 December 2022, 17:56:08 UTC Explicitly stage strided loads (#7230) * Add a pass to do explicit densification of strided loads * densify more types of strided load * Reorder downsample in local laplacian for slightly better performance * Move allocation padding into the IR. Still WIP. * Simplify concat_bits handling * Use evidence from parent scopes to densify * Disallow padding allocations with custom new expressions * Add test for parent scopes * Remove debugging prints. Avoid nested ramps. * Avoid parent scope loops * Update cmakefiles * Fix for large_buffers * Pad stack allocations too * Restore vld2/3/4 generation on non-Apple ARM chips * Appease clang-format and clang-tidy * Silence clang-tidy * Better comments * Comment improvements * Nuke code that reads out of bounds * Fix stage_strided_loads test * Change strategy for loads from external buffers Some backends don't like non-power-of-two vectors. Do two overlapping half-sized loads and shuffle instead of one funny-sized load. * Add explanatory comment to ARM backend * Fix cpp backend shuffling * Fix missing msan annotations * Magnify heap cost effect in stack_vs_heap performance test * Address review comments * clang-tidy * Fix for when same load node occurs in two different allocate nodes 16 December 2022, 17:56:08 UTC
382f813 Steven Johnson 16 December 2022, 17:54:21 UTC Fix "may be used uninitialized" warnings in Codegen_C::print_scalarized_expr() (#7244) 16 December 2022, 17:54:21 UTC
da6746e Steven Johnson 14 December 2022, 05:29:45 UTC correctness/exception.cpp needs to check HALIDE_WITH_EXCEPTIONS (fixes #7240) (#7241) correctness/exception.cpp needs to check HALIDE_WITH_EXCEPTIONS 14 December 2022, 05:29:45 UTC
1a4a469 Andrew Adams 13 December 2022, 16:11:54 UTC Fix some sources of signed integer overflow in the compiler (#7231) * Fix some sources of signed integer overflow in the compiler Also, use compiler intrinsics when possible to handle overflow, as it generates faster code. * Fix msvc macro * Must use result * Actually perform the requested operation 13 December 2022, 16:11:54 UTC
533e6e5 Steven Johnson 12 December 2022, 20:54:46 UTC Remove rogue string suffix in simd_op_check_arm.cpp (#7227) * Remove rogue string suffix in simd_op_check_arm.cpp Interestingly, it compiles here, but in some compilers it will fail with "unexpected token". * Update simd_op_check_arm.cpp 12 December 2022, 20:54:46 UTC
6ecdcbd Steven Johnson 11 December 2022, 18:05:55 UTC Tighten alignment promises for halide_malloc() (#7222) This makes a couple of changes to the behavior/implementation of `halide_malloc()`: * Currently, halide_malloc must return a pointer aligned to the maximum meaningful alignment for the platform for the purpose of vector loads and stores. 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. (It also changes apps/hannk to stop using it.) 11 December 2022, 18:05:55 UTC
16421a7 Steven Johnson 09 December 2022, 17:21:30 UTC Revise simd_op_check tests to ignore HL_TARGET (#7207) (#7216) * Revise simd_op_check tests to ignore HL_TARGET (#7207) The simd_op_check tests have historically only run using the value of HL_TARGET, which mean that the coverage they had was low (since HL_TARGET is only set to values that are runnable on at least one buildbot). 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. On all platforms, they still compile to assembly and verify that the correct instructions are generated; additionally, if the host platform can JIT for the given target, it verifies that the results are as expected. * Update simd_op_check_riscv.cpp * Update simd_op_check_x86.cpp * Update simd_op_check_x86.cpp * Update simd_op_check_arm.cpp * Add more features that must match; re-enable the bfloat instructions * Update simd_op_check_x86.cpp * Update simd_op_check_riscv.cpp * trigger buildbots * Fix simd_op_check_wasm 09 December 2022, 17:21:30 UTC
ba31688 Steven Johnson 09 December 2022, 01:22:54 UTC Increase __clang_major__ check in Float16.h to 16 (#7224) 09 December 2022, 01:22:54 UTC
066559b Steven Johnson 08 December 2022, 23:35:01 UTC Remove check_jit_user_context() from V8 bindings (#7220) Obsolete code from early V8 work, it can trigger inappropriately in some corner-case scenarios. Remove it entirely to avoid false errors. 08 December 2022, 23:35:01 UTC
8fa8221 Steven Johnson 08 December 2022, 04:34:13 UTC Fix bonehead version-checking test in HalideBuffer.h for Apple (#7218) 08 December 2022, 04:34:13 UTC
e8615bb Steven Johnson 08 December 2022, 01:22:38 UTC clang-tidy: add [[maybe-unused]] to the DECLARE_NO_INITMOD stubs. (#7215) 08 December 2022, 01:22:38 UTC
a7fa32e Steven Johnson 07 December 2022, 17:31:01 UTC Use aligned_alloc() as default allocator for HalideBuffer.h on most platforms (#7190) Use aligned_alloc() as default allocator for HalideBuffer.h on most platforms (See also https://github.com/halide/Halide/pull/7189) Modify H::R::Buffer to default to using `aligned_alloc()` instead of `malloc()`, except: - If user code passes a non-null `allocate_fn` or `deallocate_fn`, we always use those (and/or malloc/free) - If the code is compiling under MSVC, never use `aligned_alloc` (Windows doesn't support it) - If HALIDE_RUNTIME_BUFFER_USE_ALIGNED_ALLOC is defined to be 0, never use `aligned_alloc` (this is to allow for usage on e.g. older Android and OSX versions which don't provide `aligned_alloc()` in the stdlib, regardless of C++ versions.) Also, as with #7189, this ensures that the allocated space has the start of the host data as 128-aligned, and also now ensures that the size allocated 128-aligned (rounding up as needed). 07 December 2022, 17:31:01 UTC
8ce1212 Steven Johnson 07 December 2022, 17:29:19 UTC Fix bitrot in PowerPC testing (#7211) * Fix bitrot in PowerPC testing (See #7208) - DataLayout was wrong (and has been for a long time) - simd_op_check_powerpc had errors. Some were easy to fix; the rest I commented out with a TODO since this backend doesn't appear to be in active use. (Want to fix this in preparation for fixing #7207) * Move x86 absd tests to the right place Co-authored-by: Andrew Adams <andrew.b.adams@gmail.com> 07 December 2022, 17:29:19 UTC
35020c5 Zalman Stern 07 December 2022, 07:15:46 UTC Extend LLVM IR type mangling to handle scalars. (#7212) Extend LLVM IR type mangling to handle scalars and use this in vector predication intrinsic codegen. Fixes an error denerating vector predicated strided stores. 07 December 2022, 07:15:46 UTC
d4b4c50 Zalman Stern 07 December 2022, 07:15:10 UTC Add RISC V zvl flag for LLVM version 16 or greater. (#7209) 07 December 2022, 07:15:10 UTC
e0d1e15 Zalman Stern 07 December 2022, 00:58:28 UTC Fix issue with vector predicated comparison and select instructions. (#7205) Fix invalid LLVM IR issues with vector predicated comparison and select instructions. Add start of RISC V simd_op_check test. 07 December 2022, 00:58:28 UTC
59f5412 Zalman Stern 06 December 2022, 22:57:24 UTC Add bridging for clang _Float16 type. (#7201) Add type bridging between Halide::float16_t and _Float16 if the compiler supports the latter. Testing is done using clang specific logic and may need to be extended for other compilers. I chose not to add support for __fp16 and __bf16 right now as __fp16 is less useful in being storage only and __bf16 also only supports a subset of operations and was running into undefined symbols during compilation that did not look promising.

90459b0 Steven Johnson 06 December 2022, 00:53:05 UTC Revert "Fix for top-of-tree LLVM" (#7200) Revert "Fix for top-of-tree LLVM (#7194)" This reverts commit a9ea9b565018774e52bb4028cbc91e14cb86959e. 06 December 2022, 00:53:05 UTC
345cf18 Steven Johnson 02 December 2022, 20:48:57 UTC Don't attempt to use makecontext()/swapcontext() on Android (#7196) Despite being 'posixy', it doesn't actually implement these calls. 02 December 2022, 20:48:57 UTC
a9ea9b5 Steven Johnson 02 December 2022, 00:17:48 UTC Fix for top-of-tree LLVM (#7194) 02 December 2022, 00:17:48 UTC
43911f4 Steven Johnson 01 December 2022, 18:20:03 UTC Add a -v flag to generator_main() (#7193) This is a simple thing that just logs the path to all generated file(s) to stdout if `-v=1` is specified. It's intended for people running Generators directly from the commandline, and is intended as a more user-friendly alternative to HL_DEBUG_CODEGEN=1. No makefiles, etc specify it at present, but I anticipate using it in some tooling in the future. Example usage: ``` $ resize_image_bilinear.generator_binary -v 1 -o /tmp -g resize_image_bilinear -n resize_image_bilinear_uint16 -f resize_image_bilinear_uint16 -e assembly,c_header,llvm_assembly,registration,static_library,stmt 'target=arm-64-android' 'input.type=uint16' 'output.type=uint16' Generated file: /tmp/resize_image_bilinear_uint16.s Generated file: /tmp/resize_image_bilinear_uint16.h Generated file: /tmp/resize_image_bilinear_uint16.ll Generated file: /tmp/resize_image_bilinear_uint16.registration.cpp Generated file: /tmp/resize_image_bilinear_uint16.a Generated file: /tmp/resize_image_bilinear_uint16.stmt ``` 01 December 2022, 18:20:03 UTC
5a8c324 Steven Johnson 30 November 2022, 01:44:30 UTC Fix metadata generation for multitarget Generators (#7181) Fix metadata generation for multitarget Generators We had a mechanism in place to ensure that Outputs that got renamed during lowering still emitted the proper names in the metadata... but this didn't work reliably for Multitarget generation. Now it does. 30 November 2022, 01:44:30 UTC
caf4b71 Steven Johnson 29 November 2022, 17:45:49 UTC Disable unreachable-code clang-tidy warnings (#7182) Some configurations of clang-tidy will (correctly) complain that the code inside the `if` clauses here will never be executed, since it ends up as something like `if (strcmp("foo", "foo"))`... but for testing purposes, we want to keep it, for obvious reasons. It's hard to construct a string-compare here as constexpr, so I'm just going to NOLINT it. Also changed the `count_buffers()` check to a static_assert for simplicity. 29 November 2022, 17:45:49 UTC
2cfc315 Steven Johnson 28 November 2022, 22:11:35 UTC Tweak the import paths in Python apps & tests (#7179) * Tweak the import paths in Python apps & tests This change makes it a bit easier for me to transform the import paths when merging into Google: we can't set PYTHONPATH, and calling `sys.path.append()` is frowned upon. This should have no effect on the GitHub repo but will make my life easier downstream. * More tweaks * force builds * Update Generator.cpp 28 November 2022, 22:11:35 UTC
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

58421be Steven Johnson 08 November 2022, 16:54:15 UTC Call cache.clear between internal functions in CG_C (#7155) We didn't call cache.clear() between internal functions in the C backend, so the cache could try to re-use something declared in a previous (internal, closure) function and would fail to compile. Easy fix. (I'm surprised we haven't seen this fail before now.) 08 November 2022, 16:54:15 UTC
c6815b0 Steven Johnson 08 November 2022, 16:53:43 UTC C Backend should call halide_buffer_to_string() (#7156) Just assume that this is present and call it for stringify() on buffers in the C backend. (If it's missing, the user will be expected to provide an implementation, as is usual for runtime with the C backend.) 08 November 2022, 16:53:43 UTC
102c059 Andrew Adams 08 November 2022, 00:38:44 UTC Fix readnone attribute for llvm 16 (#7152) * Fix readnone attribute for llvm 16 The readnone flag was changed to memory(none) when applied to functions. llvm-as dynamically upgrades readnone applied to functions, so our .ll is fine for now, but there were places in the compiler we were manually sticking 'readnone' on a function.

8f8edeb Steven Johnson 03 November 2022, 20:37:51 UTC Don't use TF_LITE_KERNEL_LOG in apps/hannk (#7147) TF_LITE_KERNEL_LOG was intended for TFLite Micro but usage leaked out into example code; we should use ReportError instead. 03 November 2022, 20:37:51 UTC
1230042 Steven Johnson 02 November 2022, 00:10:51 UTC Fix Python wheel-building (#7144) Various bits of code rearrangement had invalidated some of the build scripts for Python wheels for our bindings; this fixes that, and also subtracts some other irrelevant stuff that was getting included (e.g. the stub directory). Also updated the "long description" to use README_python.md rather than README.md. 02 November 2022, 00:10:51 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

(Note that in C++ we don't always range-check for these operations -- it's limited to `assert()` checks -- but in Python the expectations are clearly different.) 27 October 2022, 02:22:38 UTC

This is particularly useful for RISC V, but it may be a simpler, better optimized path, for Halide vector operations in general. Add support for a maximum vector size that might be larger than the native vector size. RISC V vector LMUL support is an example of an architecture supporting this. 25 October 2022, 05:24:32 UTC

Specifically: (1) if we are building a JIT shared runtime (ie, we are jitting), and we are compiling with MSAN enabled (detected via preprocessor), we should always use the real MSAN stubs, even if the Target::MSan feature has been cleared (because JITModule::make_module() clears it).
