02046ac Steven Johnson 19 July 2021, 17:09:25 UTC Merge branch 'master' into srj/hannk-mmap 19 July 2021, 17:09:25 UTC
557c8e4 Dillon Sharlet 16 July 2021, 17:56:05 UTC Fix Hexagon vrmpy with 16-bit results (#4248) (#6137) * Fix #4248 * clang-format 16 July 2021, 17:56:05 UTC
769b855 Dillon Sharlet 15 July 2021, 16:22:28 UTC Add optimization for corner case in conv (#6139) * Add silly optimization for weird cases. * Use transpose 15 July 2021, 16:22:28 UTC
42e1d45 Steven Johnson 15 July 2021, 16:02:00 UTC [hannk] Allow aliasing of Reshape tensors (#6138) * Allow aliasing of Reshape tensors Previously we didn't allow this because aliased tensors had to have the same rank, which is ~never the case for Reshape. Aliasing for Reshape is a huge win because it essentially becomes a no-op rather than a memcpy. Running against standard set of models shows no regression in differences vs. tflite. 15 July 2021, 16:02:00 UTC
19f2bc7 Dillon Sharlet 14 July 2021, 00:20:25 UTC Reduce verbosity of compare_vs_tflite further (#6136) 14 July 2021, 00:20:25 UTC
802c22a Andrew Adams 13 July 2021, 23:13:02 UTC Don't reinterpret cast when codegenning vector concat (#6125) It confuses the HVX LLVM backend, and shouldn't be necessary anyway. 13 July 2021, 23:13:02 UTC
77207a5 Dillon Sharlet 13 July 2021, 23:04:21 UTC Optimize shallow depthwise convolutions (#6134) * Add TailStrategy::PredicateLoads and TailStrategy::PredicateStores * Different compilers * PredicateStores is faster than specialize + ShiftInwards * Update comments. * Allow PredicateStores for RVars * Fix test to avoid realize bounds query issues. * Add comments. * clang-format * predicate* is not pure * Fix documentation bugs * Don't allow PredicateStores for reductions. * Substitute more strongly around Provide * Change these back to pure for now to satisfy some logic in ScheduleFunctions * Fix use after free of pred. * Update comments. * Refactor implementation of predication * Visit predicates * Partition loops with predicated loads/stores. * Clean up ApplySplit * Fix inappropriate predicated vectorization of VectorReduce * De-dup GuardWithIf and Predicate * These also handle scalar predicated loads/stores. * Print provide predicates * Don't allow predicated non-innermost splits. * Remove debugging code * Forgot to add new file * Add test to CMake build * Fix bug in simplification of extract_element * Fix issue with mixing uses of guarded expressions inside and outside calls. * Don't lift impure exprs. * clang-format * clang-format again * Add "shallow" version of depthwise for small numbers of channels. * Better name for input_stride_x * Fix performance regression in deep case. * Update performance * Missed rename * Enable tiling of shallow case. * Require x be a dummy dim for shallow depthwise * Small cleanup to avoid ternary * clang-format * Can't use shallow depthwise when stride_x != 1 13 July 2021, 23:04:21 UTC
a762c34 Dillon Sharlet 13 July 2021, 21:54:11 UTC Add TailStrategy::PredicateLoads and TailStrategy::PredicateStores (#6126) * Add TailStrategy::PredicateLoads and TailStrategy::PredicateStores * Different compilers * PredicateStores is faster than specialize + ShiftInwards * Update comments. * Allow PredicateStores for RVars * Fix test to avoid realize bounds query issues. * Add comments. * clang-format * predicate* is not pure * Fix documentation bugs * Don't allow PredicateStores for reductions. * Substitute more strongly around Provide * Change these back to pure for now to satisfy some logic in ScheduleFunctions * Fix use after free of pred. * Update comments. * Refactor implementation of predication * Visit predicates * Partition loops with predicated loads/stores. * Clean up ApplySplit * Fix inappropriate predicated vectorization of VectorReduce * De-dup GuardWithIf and Predicate * These also handle scalar predicated loads/stores. * Print provide predicates * Don't allow predicated non-innermost splits. * Remove debugging code * Forgot to add new file * Add test to CMake build * Fix bug in simplification of extract_element * Fix issue with mixing uses of guarded expressions inside and outside calls. * Don't lift impure exprs. * clang-format * clang-format again 13 July 2021, 21:54:11 UTC
867b6c8 Steven Johnson 13 July 2021, 20:01:21 UTC [hannk] Make compare_vs_tflite with --verbose 0 less noisy (#6135) Minor fixes to eliminate noise. 13 July 2021, 20:01:21 UTC
e705253 Steven Johnson 13 July 2021, 01:17:41 UTC [hannk] Implement greedy algorithm in AllocationPlanner (#6117) * [hannk] Rework most of hannk's Tensor storage to be arena-based. * Update interpreter.cpp * Restore get_tensor * clang-format * Add missing include * Fix arena alignment issues * Remove redundant assert * Rework AllocationPlanner API a bit * [hannk] Implement greedy algorithm in AllocationPlanner This uses a basic greedy approach to doing an allocation plan for tensors in hannk. Initial testing shows exact result matches between old and new code. Drive-by changes: - Change Interpreter's `verbose` -> `verbosity` to allow more output granularity, and update callers as needed. - Fix two places in ModelRunner that should have called the function hooks rather than the functions directly. * clang-format * Add missing includes * Add missing includes * trigger buildbots * Minor fixes and comments in AllocationPlanner * Suggested fixes 13 July 2021, 01:17:41 UTC

3e9cb4f Steven Johnson 12 July 2021, 23:22:05 UTC Fix wasm regression at ToT LLVM (#6132) llvm.wasm.promote.low was removed. Calling fpext directly is the preferred approach now. 12 July 2021, 23:22:05 UTC
5bfa686 Steven Johnson 12 July 2021, 18:08:18 UTC Merge branch 'master' into srj/hannk-mmap 12 July 2021, 18:08:18 UTC
a2c47a9 aankit-ca 08 July 2021, 19:22:22 UTC [Hexagon] Use LLVM masked stores. (#6129) * [Hexagon] Use LLVM masked stores. Letting CodeGen_LLVM handle predicated stores for Hexagon allows us to generate HVX predicated stores instead of scalar predicated stores. * Corrections to run haank on hexagon-sim Co-authored-by: Ankit Aggarwal <aankit@quicinc.com> 08 July 2021, 19:22:22 UTC
f48a8da Zalman Stern 07 July 2021, 23:33:53 UTC Adding padding byte size to outermost header byte count in MATLAB5 file format.

240f6a3 Alexander Root 01 July 2021, 14:55:28 UTC Use bound_correlated_differences in find_constant_bounds (#6059) * move PartiallyCancelDifferences to outside of SimplifyCorrelatedDifferences * add a rule to address #6044 correlation * use bound_correlated_differences in find_constant_bounds 01 July 2021, 14:55:28 UTC
f7aa53b Steven Johnson 30 June 2021, 19:24:19 UTC Remove deprecated realize() variants from Func and PIpeline (#6122) These were deprecated in Halide 12. Let's remove them for Halide 13. 30 June 2021, 19:24:19 UTC
d1d7359 Andrew Adams 29 June 2021, 23:15:12 UTC Relax overzealous pruning rule (#6115) We don't allow schedules that fuse to the extent that we can no longer vectorize. This was implemented incorrectly though. The check assumed that something was going to be compute_at inside the innermost loop, and neglected the possibility that we were about to tile that loop. 29 June 2021, 23:15:12 UTC
84b78da Svenn-Arne Dragly 29 June 2021, 22:27:00 UTC Fix potential undefined behavior in `set_flag` (#6118) Previously, the Clang UndefinedBehaviorSanitizer (UBSan) complained about potential undefined behavior in `halide_buffer_t::set_flag` because the enum `halide_buffer_flags` is interpreted as an int32_t and implicitly converted to a uint64_t: ``` runtime error: implicit conversion from type 'int' of value -2 (32-bit, signed) to type 'unsigned long' changed the value to 18446744073709551614 (64-bit, unsigned) ``` On most compilers and hardware, this causes no issues, since the conversion and implementation of `set_flag` together produce the expected behavior still. However, it is better to be on the safe side and make the explicit conversion to a uint64_t before doing the bitwise negation. This change makes sure the conversion from int32_t is made before the bitwise negation, which fixes the potential undefined behavior and keeps UBSan from complaining. 29 June 2021, 22:27:00 UTC
a4652e7 Steven Johnson 29 June 2021, 22:26:08 UTC trigger buildbots 29 June 2021, 22:26:08 UTC

408a277 Steve Suzuki 28 June 2021, 17:57:29 UTC Float16 support in CodeGen_ARM (#6102) * Add definition of Target::ARMFp16 Add the definition of the feature for ARMv8.2-a half-precision floating point data processing * Added test to generate 'float16' neon assembly; * Add check for data type in float16 NEON test The test simd_op_check doesn't check the suffix of operand which indicates the data type in case of AArch64 NEON instruction. e.g. FADD V0.4S, V0.4S, V0.4S In order to distinguish instruction of fp16 from fp32, the suffix such as ".4S" in the above needs to be checked. * Generate float16 Arm aarch64 LLVM-IR Armv8-a extension of Half-precision floating point data processing is supported by CodeGen_ARM. The target needs to be set as 64-bit with "arm_fp16" feature. 32-bit is not supported in this commit. Upgrading fp16 to fp32 with emulated conversion is replaced with either fp16 native instruction or fp32 operation with native type conversion of fp16-fp32 * Fix format and comments for arm_fp16 feature Co-authored-by: Liam O'Neil <liam.oneil@arm.com> 28 June 2021, 17:57:29 UTC

2816567 Alex Reinking 26 June 2021, 00:39:42 UTC Enable ubuntu packaging (#6113) * Revert "Disable Ubuntu Packaging Action (Issue #6111) (#6112)" This reverts commit 3f3dd702 * Explicitly update to avoid out of date package lists. Fixes #6111 26 June 2021, 00:39:42 UTC
0da1354 Steven Johnson 25 June 2021, 23:24:33 UTC Avoid pathological cases in halide_benchmark() (#6110) In the variant that tries to compute a good samples/iters value based on min_time, there's a pathological case if the environment's timer is relatively coarse, and the op being profiled is relatively fast; in this case, you can end up with timings that are very close to zero (or *literally* zero), and our attempt to calculate the number of iterations can explode into the billions, making the benchmark appear to hang (as it may take an absurd length of time to run). To fix this, add a maximum value for iters_per_sample, and smarten the calculation for when the measured time is tiny. 25 June 2021, 23:24:33 UTC

93292a2 Steven Johnson 22 June 2021, 20:51:20 UTC [hannk] Add --keep_going flag to ModelRunner (#6101) This allows you to run a compare operation against a bunch of graphs without exiting at the first one that is out-of-spec for comparison. (Useful when you want to verify that no *new* differences are introduced by a change.) 22 June 2021, 20:51:20 UTC

af628a7 Steven Johnson 03 June 2021, 23:39:03 UTC Fix dubious "gather" intrinsic for hvx (#6069) I'm not sure if this is a bug (per se) or not, but: We define an intrinsic for `Call::hvx_gather`, and at several points check for `is_intrinsic(Call::hvx_gather)`, but we never actually create such a Call. Instead, `make_gather` just uses the naked string `"gather"`, which is not the same thing. How is this working? (Is it working?) Opening this as a PR to gather input (no pun intended) about what's going on here. 03 June 2021, 23:39:03 UTC

445ddd0 Steven Johnson 27 May 2021, 23:14:21 UTC Allow hannk-delegate input and output tensors to share memory with tflite (#6030) * Allow hannk-delegate input and output tensors to share memory with tflite We previously allocated duplicate memory buffers for the input and output tensors, and just copied them back and forth as needed, which wastes memory and cycles. Now, we declare the input and output tensors to be 'external', and update the host pointer before every interpreter run. Note that dynamic tensors are still a bit of a special case: we still do duplicate allocations there (plus memcpy), because in the most general case we can't know the final size needed until we run the pipeline, but we need to allocate that output to run the pipeline. There are ways we could finesse this -- e.g., give dynamic tensors a lambda callback to allow them to resize the TFLite tensor and then use that storage -- but since dynamic tensors don't seem to be common or large in our test cases, I'm doing it this way for now. (I may circle back and try the lambda approach later.) Note that this moves the implicit init of `is_constant_` out of the Tensor ctor, and instead always requires an explicit call to `set_constant()`, which I think makes the situation much clearer. * Update hannk_delegate.cpp 27 May 2021, 23:14:21 UTC
