(There was a todo about "find a better place for generate_closure_ir()"; this PR eliminates it entirely, just inlining it into the caller, which I think is reasonable given thhe number of assumptions the caller has to make in the first place...) * Update LowerParallelTasks.cpp | 16 December 2021, 19:30:06 UTC |

c3ff4d2 | Steven Johnson | 14 December 2021, 00:32:31 UTC | Restore support for using V8 as the Wasm JIT interpreter (#6478) * Support using V8 as the Wasm JIT interpreter This is a partial revert of https://github.com/halide/Halide/pull/5097. It brings back a bunch of the code in WasmExecutor to set up and use V8 to run Wasm code. All of the code is copy-pasted. There are some small cleanups to move common code (like BDMalloc, structs, asserts) to a common area guarded by `if WITH_WABT || WITH_V8`. Enabling V8 requires setting 2 CMake options: - V8_INCLUDE_PATH - V8_LIB_PATH The first is a path to v8 include folder, to find headers, the second is the monolithic v8 library. This is because it's pretty difficult to build v8, and there are various flags you can set. Comments around those options provide some instructions for building v8. By default, we still use the wabt for running Wasm code, but we can use V8 by setting WITH_WABT=OFF WITH_V8=ON. Maybe in the future, with more testing, we can flip this. Right now this requires a locally patched build of V8 due to https://crbug.com/v8/10461, but once that is resolved, the version of V8 that includes the fix will be fine. Also enable a single test, block_transpose, to run on V8, with these results: $ HL_JIT_TARGET=wasm-32-wasmrt-wasm_simd128 \ ./test/performance/performance_block_transpose Dummy Func version: Scalar transpose bandwidth 3.45061e+08 byte/s.

46d8ca8 | Zalman Stern | 14 December 2021, 00:31:45 UTC | Move parallel/async lowering from LLVM codegen to a standard Halide IR lowering pass. (#6195) * First cut at factoring parallel task compilation, including closure generating and calling, into a normal IR to IR lowering pass. Includes adding struct handling intrinsics to LLVM and C++ backends. Still a work in progress. * Fix formating that got munged by emacs somehow. * Checkpoint progress. * Small fixes. * Checkpoint progress. * Checkpoint preogress. * Checkpoint progress. * Checkpoint progress. Debugging code will be removed. * Try a fix for make_typed_struct in C++ codegen. * Another attempt to fix C++ codegen. * Another C codegen fix. * Checkpoint progress. * Use make_typed_struct rather than make_struct to construct closure.

First, this should have been a rounding_shift_right. Some patterns were missing in FindIntrinsics. Second, rounding_shift_right had suboptimal codegen in the case where the second arg is a positive const. On archs without a rounding shift right instruction you can further rewrite this to: shift_right(rounding_halving_add(x, 7), 3) which is just two instructions on x86. | 13 December 2021, 20:00:52 UTC |

This is a bad assumption, as it can call device_crop(), which can fail due to unexpected runtime errors, or from a backend simply leaving the device_crop field at the default (unimplemented) case (as is currently the case for the OGLC backend). When this happens, the dst buffer was left in an inconsistent, invalid state (which was what led to the crashes fixed by #6401). This change modifies _halide_buffer_crop() to return nullptr in the event of an error, and ensure that all cropped buffers are checked for null at the right point. (This is not optimal, of course, since the specific error returned by device_crop is getting dropped on the floor, but the existence of an error is no longer ignored.)

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 |

While the mix function have overloads to boolean vectors, it is only supported in version 4.5, so it is not exactly portable.

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.

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 |

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 |

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 |

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.
