8e34a35 | Steven Johnson | 09 November 2021, 23:10:40 UTC | Remove halide_abort_if_false() usage in runtime/metal (#6398) * Remove halide_abort_if_false() usage in runtime/metal This converts all the usage of `halide_abort_if_false()` in runtime/metal into either an explicit runtime check-and-return-error-code (if the check looks plausible), or `halide_debug_assert()` (if the check seems to be stating an invariant that shouldn't be possible in well-structured code). These changes are admittedly subjective, so feedback is especially welcome. Also, driveby change to sync-common.h to use `halide_debug_assert()` rather than a local equivalent. * nits | 09 November 2021, 23:10:40 UTC |
4f70271 | Steven Johnson | 09 November 2021, 22:51:05 UTC | Add defensive checks to halide_buffer_copy_already_locked (#6401) Found while debugging crashes with performance_async_gpu for OpenGLCompute: the 'if' tree wasn't robust enough for malformed buffers being passed, and could attempt to deref and use a null src->device_interface or dst->device_interface in some cases. This patch just improves this function to return an error in these cases (rather than crashing); the fact that we are getting malformed buffers passed to us is likely a separate bug. | 09 November 2021, 22:51:05 UTC |

Also simplified to use only public API, updated the expected correctness, and avoided the need to have cuda present on the system to test for cuda output (since we can cross-compile to generate the C++ output anywhere). * fixes * Fix Windows text file endings * Update pytorch.cpp * Update pytorch.cpp | 09 November 2021, 21:25:26 UTC |
4286c78 | Steven Johnson | 09 November 2021, 17:13:09 UTC | Drop support for LLVM11 (#6396) * Drop support for LLVM11 With Halide 13 released, we should drop support for LLVM11 in Halide trunk, since we only promise to support LLVM trunk + two releases. * Update packaging.yml * Update config.cmake * Update CMakeLists.txt | 09 November 2021, 17:13:09 UTC |
d3ea755 | Steven Johnson | 09 November 2021, 17:03:17 UTC | Fix OGLC debug builds (#6399) If you try to build and run something with `openglcompute` and `debug`, you may crash with a div-by-zero, because the openglcompute runtime never calls `halide_start_clock()`, and all implementations of `halide_current_time_ns()` assume that it has been called. On (e.g.) OSX, this results in div by zero. This fixes it by inserting the correct call into openglruntime.cpp, and also adding debug-only asserts to all the `halide_current_time_ns()` implementations. (I was tempted to fix this by removing `halide_start_clock()` entirely and just lazily initing the initial value in `halide_current_time_ns()`, but I figured that would likely get pushback...) | 09 November 2021, 17:03:17 UTC |
d6f1345 | Steven Johnson | 08 November 2021, 23:13:13 UTC | Rename halide_assert -> halide_abort_if_false (#6382) * Rename halide_assert -> HALIDDE_CHECK A crashing bug got mistakenly inserted because a new contributor (reasonably) assumed that the `halide_assert()` macro in our runtime code was like a C `assert()` (i.e., something that would vanish in optimized builds). This is not the case; it is a check that happens in all build modes and always triggers an `abort()` if it fires. We should remove any ambiguity about it, so this proposes to rename it to somethingmore like the Google/Abseil-style CHECK() macro, to make it stand out more. (We may want to do a followup to verify that all of the uses really are unrecoverable errors that aren't better handled by returning an error.) * clang-format * Fix for top-of-tree LLVM * Fix for older versions * HALIDE_CHECK -> halide_abort_if_false * Update runtime_internal.h | 08 November 2021, 23:13:13 UTC |

26ccb54 | Omar Emara | 04 November 2021, 00:35:13 UTC | Support vectorized Select in OpenGLCompute backend (#6371) The ternary operator in GLSL does not work with vector types. While the mix function have overloads to boolean vectors, it is only supported in version 4.5, so it is not exactly portable. To work around this, we use the ternary operator on all elements of the vector type. Necessary for #6348. | 04 November 2021, 00:35:13 UTC |
c005b9f | Omar Emara | 04 November 2021, 00:32:20 UTC | Support vectorization in OpenGLCompute backend (#6348) * Support vectorization in OpenGLCompute backend This patch adds support for vector load and store operations. First, a pass identifies the buffers whose loads and stores are all dense, aligned, and have the same number of lanes. Such buffers are declared with a vector base type and accessed accordingly. Loads and stores that do not satisfy those criteria are implemented as gathers and scatters from buffers whose base type is scalar. Resolves #4976. Partially resolves #1687. * Move buffer name instead of copy (clang-tidy) | 04 November 2021, 00:32:20 UTC |

76315a2 | Omar Emara | 03 November 2021, 22:54:44 UTC | Vectorize Ramp in OpenGLCompute backend (#6372) Currently, ramps are generated as a number of independent scalar expressions that are finally gathered into a vector. For instance, indexing in vectorized code is filled with ramps like the following: ``` int _11 = int(1) * int(1); int _12 = _10 + _11; int _13 = int(2) * int(1); int _14 = _10 + _13; int _15 = int(3) * int(1); int _16 = _10 + _15; ivec4 _17 = ivec4(_10, _12, _14, _16); ``` This patch simplifies the generated code using a multiply add expression on a vector containing an arithmetic expression, such that the code is as follows: ``` ivec4 _11 = ivec4(0, 1, 2, 3) * int(1) + _10; ``` This is more performant due to vectorization, more compact, and more readable because the base and the stride are easily identifiable. | 03 November 2021, 22:54:44 UTC |
2cf3afb | Steven Johnson | 03 November 2021, 22:47:03 UTC | [hannk] Fix MeanOp (#6336) * [hannk] Fix MeanOp The `reducing()` method didn't handle negative values for indices, and didn't reverse the value of the axis as we do elsewhere, so results were incorrect. Also, we now parse and save the value of `keep_dims`, though I can't find evidence that it does much of anything: test cases pass different values for it but none of them fail (even though we ignore it), and at least one reference implementation I see doesn't seem to do anything with it. * Remove keep_dims handling for MeanOp | 03 November 2021, 22:47:03 UTC |
7ec8d70 | Steven Johnson | 03 November 2021, 22:19:15 UTC | Convert various halide_assert -> static_assert (#6383) The type-size checks in d3d12compute.cpp don't need to be runtime checks. | 03 November 2021, 22:19:15 UTC |
a227440 | Steven Johnson | 03 November 2021, 20:55:28 UTC | Remove halide_assert() from halide_default_device_wrap_native (#6381) This was inserted in https://github.com/halide/Halide/pull/6310, probably mistakenly, since `halide_assert()` in the Halide runtime is *not* a debug-only assertion). Instead of a controlled runtime failure, we just abort, which is not OK. | 03 November 2021, 20:55:28 UTC |

4225eba | Alex Reinking | 01 November 2021, 23:03:09 UTC | Add helper for cross-compiling Halide generators. (#6366) * Add helper for cross-compiling Halide generators. Created a new function, `add_halide_generator`, that helps users write correct cross-compiling builds by establishing the following convention for creating a generator named `TARGET`: 1. Define Halide generators and libraries in the same project 2. Assume two builds: a host build and a cross build. 3. When creating a generator, check to see if we can load a pre-built version of the target. 4. If so, just use it. 5. If not, make sure the full Halide package is loaded and create a target for the generator. a. If `CMAKE_CROSSCOMPILING` is set, then _warn_ the user (the variable is unreliable on macOS) that something seems fishy. b. Create export rules for the generator. It creates a package `PACKAGE_NAME` and appends to its `EXPORT_FILE`. c. Create a custom target also named `PACKAGE_NAME` for building the generators. d. Create an alias `${PACKAGE_NAMESPACE}${TARGET}`. 6. Users are expected to use the alias in conjunction `add_halide_library`. Users can test the existence of `TARGET` to determine whether a pre-built one was loaded (and set additional properties if not). 7. Setting `${PACKAGE_NAME}_ROOT` is enough to load pre-built generators. `PACKAGE_NAME` is `${PROJECT_NAME}-halide_generators` by default. `PACKAGE_NAMESPACE` is `${PROJECT_NAME}::halide_generators::` by default. `EXPORT_FILE` is `${PROJECT_BINARY_DIR}/cmake/${PACKAGE_NAME}-config.cmake` by default. Users are free to avoid the helper if it would not fit their workflow. * Make HANNK use the new add_halide_generator helper | 01 November 2021, 23:03:09 UTC |

This cleans it up and makes a clear distinction between aliasing done to overlay buffers with crop-and-translate, vs the aliasing done when we reshape tensors. We no longer allow a given tensor to do both of these, and we give preference to Reshape aliasing first.

Rather than shelling out via execute_process and potentially guessing the toolchain options wrong, expect to find our host tools (i.e. generators) in a package called "hannk_tools". The package is created by the host build via the CMake export() command. Importing this package in the cross build creates IMPORTED targets with the same names as our generators. We then use these generators rather than creating generators for the target build. * Rework cross-compiling script. * Respond to (easy) reviewer comments. * Add HANNK_AOT_HOST_ONLY option.

47fa87f | Steven Johnson | 26 October 2021, 17:22:49 UTC | [hannk] Add a prepare() method for ops and interp (#6338) * [hannk] Add a prepare() method for ops and interp This adds a new method to the Interpreter, and to all ops, which allows the interpreter (and each op) to do any one-time preparation for future executions. Previously this was lumped into either the Interpreter's ctor, or the Ops various other methods, but this has some nice advantages at minimal cost: - Since the new prepare() returns an error value, it allows the Interpreter to do sanity checking at startup and return an error to the caller (rather than simply crashing); this makes using it in some runtime environments less painful. - Ops can use this to prep and cache information for multiple subsequent runs; initially, Conv and DepthwiseConv use this to calculate and cache the alignment requirements they need later on. This is unlikely to be a huge performance hit, but it is likely nonzero, and As an added bonus, this means that e.g. the map_bounds() method is no longer susceptible to runtime failures from Halide bounds queries. * Update interpreter.cpp * Update transforms.cpp * Update transforms.cpp | 26 October 2021, 17:22:49 UTC |

It also makes it tractable to to do a `switch` on a series of `halide_type_t`, since we can now use halide_type_t::as_u32() as a constexpr. There were a number of places that did this in an ad-hoc manner previously; I updated those, and also converted at least one more repeated-if clause into a switch. (TBH, I'm not sure if I'm wild about the syntax, though; it is a bit weedy to scan. Suggestions welcome.) * Ensure there are no uninited vars in constexpr funcs * Update HalideRuntime.h | 26 October 2021, 17:05:48 UTC |

5e374bc | Omar Emara | 25 October 2021, 20:34:07 UTC | Fix default device wrap native function (#6310) * Fix default device wrap native function Currently, an attempt to call device_wrap_native on a target that uses the default device wrap native function will result in an error of type halide_error_device_interface_no_device, namely in the OpenGLCompute and the Hexagon targets. This happens because the default wrap native function calls debug_log_and_validate_buf after the device_interface is set in halide_device_wrap_native but before the device handle is set, which is validated as a bad state. This patch removes the validation call and adds an assert for the handle much like the other wrap_native implementations in other targets. * Use approperiate error code | 25 October 2021, 20:34:07 UTC |

Should be easy to fill in when we do. - TFLite's GatherNd op (and NNAPI's GATHER op) allow for the indices arg to be multidimensional; I rewrote the code to handle this and it's passing the acceptance tests for NNAPI's cases.

This is a general problem for patterns that widen, do some math, and then narrow. They will always get cut at the widening operation, so this PR just substitutes in all widening operations. This can't cause combinatorial blow-up, because each substitution has a wider type than the values that it depends on, so the chains can be at most 2-3 lets deep. * Make substituting in widening lets a prepass instead * Move find_intrinsics a little earlier in lowering * Handle impure subexpressions by leaving them behind at the original let site * FindIntrinsics must be after the last simplification pass | 12 October 2021, 20:52:24 UTC |

81ad45e | Andrew Adams | 01 October 2021, 21:41:29 UTC | compiler stack usage improvements (#6239) * Reduce compiler stack usage, and grant more control over stack usage I found some code in the wild that needs 9mb of stack to lower. It's a pain to even diagnose the problem definitively, because it requires plumbing platform-specific linker flags to grant more stack. This commit: - Reduces peak stack usage of similar code in the repo (the FFT) - Increases the stack size for lowering and codegen to 32mb on all platforms, using stack switching techniques. We started doing this on Windows a while ago and it hasn't bitten us, so let's try on more platforms. - Gives user control over the amount of stack used for lowering and codegen. It shouldn't be necessary except when diagnosing problems like this in future. Using the control I was able to determine that the correctness tests all pass with 500k of stack, and the apps all pass with 1MB, so 32MB ought to be enough for anybody. I found a never-checked-in test for the mux helper which uses 10MB of stack and really shouldn't need to, so I added that (and opened an issue) as an example of how to grant more stack when necessary, even though 10MB is less than our default now. Also fixed an incorrect comment on the Block node. * Fixes for macos * Add test to cmake * Fix type of temporary * Reduce number of exprs in the mux * Fix quadratic memory usage in new test * Better comment * Variable name fix * Try giving windows a little more stack * Clarify why we want a live Stmt in scope * Review comments * Check some return values * tickle buildbots * Fixes for arm macos * Remove stray character * clang-tidy had some reasonable concerns * Comment fix * Maybe windows needs yet more stack Co-authored-by: Steven Johnson <srj@google.com> | 01 October 2021, 21:41:29 UTC |

e092c01 | Steven Johnson | 29 September 2021, 23:08:38 UTC | Fix alignment issues in synchronization_common.h (#6272) * Fix alignment issues in synchronization_common.h To work around old COMDAT issues, we allocated the table as a char array and cast it to what we want; unfortunately this doesn't guarantee the right alignment for the table and in some environments (eg wasm) we can get unaligned-access failures. We could fix this by forcing the right alignment, but since we fixed COMDAT issues in another way a while back (adding smarts to LLVM_Runtime_Linker), let's just remove the hack and declare it normally. Also added some drive-by changes to ensure that the hashtable size and HASH_TABLE_BITS were safe (this happened to be the case before but wasn't enforced), and also to init all the fields in hash_bucket. (Q: do we really need `check_hash()` to exist? With the mods in place above, is it possible for addr_hash() to return a bad index?) * Always use HASH_TABLE_BITS in addr_hash() * Only use check_hash() in DEBUG_RUNTIME builds | 29 September 2021, 23:08:38 UTC |
