8864e8a Roman Lebedev 18 March 2024, 23:09:09 UTC Python bindings: `add_python_test()`: do set `HL_JIT_TARGET` too (#8156) This one took quite a bit of digging. I wanted to enable opencl tests on debian package, and `boundary_conditions.py`+`division.py` were failing when run with `HL_TARGET=host OCL_ICD_VENDORS=no-opencl-please.missing` env variables with `clGetPlatformIDs failed`, which made no sense to me. Empty `HL_JIT_TARGET` results in `opencl` being detected, unsurprisingly. 18 March 2024, 23:09:09 UTC
a132246 Andrew Adams 15 March 2024, 21:04:44 UTC Fix two compute_with bugs. (#8152) * Fix two compute_with bugs. This PR fixes a bug in compute_with, and another bug I found while fixing it (we could really use a compute_with fuzzer). The first bug is that you can get into situations where the bounds of a producer func will refer directly to the loop variable of a consumer func, where the consumer is in a compute_with fused group. In main, that loop variable may not be defined because fused loop names have been rewritten to include the token ".fused.". This PR adds let stmts to define it just inside the fused loop body. The second bug is that not all parent loops in compute_with fused groups were having their bounds expanded to cover the region to be computed of all children, because the logic for deciding which loops to expand only considered the non-specialized pure definition. So e.g. compute_with applied to an update stage would fail to compute values of the child Func where they do not overlap with the parent Func. This PR visits all definitions of the parent Func of the fused group, instead of just the unspecialized pure definition of the parent Func. Fixes #8149 * clang-tidy 15 March 2024, 21:04:44 UTC
76a7dd4 Zalman Stern 15 March 2024, 20:01:51 UTC Support for ARM SVE2. (#8051) * Checkpoint SVE2 restart. * Remove dead code. Add new test. * Update cmake for new file. * Checkpoint progress on SVE2. * Checkpoint ARM SVE2 support. Passes correctness_simd_op_check_sve2 test at 128 and 256 bits. * Remove an opportunity for RISC V codegen to change due to SVE2 support. * Ensure SVE intrinsics get vscale vectors and non-SVE ones get fixed vectors. Use proper prefix for neon intrinsics. Comment cleanups. * Checkpoint SVE2 work. Generally passes test, though using both NEON and SVE2 with simd_op_check_sve2 fails as both posibilities need to be allowed for 128-bit or smaller operations. * Remove an unfavored implementation possibility. * Fix opcode recognition in test to handle some cases that show up. Change name of test class to avoid confusion. * Formatting fixes. Replace internal_error with nop return for CodeGen_LLVM::match_vector_type_scalable called on scalar. * Formatting fix. * Limit SVE2 test to LLVM 19. Remove dead code. * Fix a degenerate case asking for zero sized vectors via a HAlide type with lanes of zero, which is not correct. * Fix confusion about Neon64/Neon128 and make it clear this is just the width multiplier applied to intrinsics. * REmove extraneous commented out line. * Address some review feedback. Mostly comment fixes. * Fix missed conflict resolution. * Fix some TODOs in SVE code. Move utility function to Util.h and common code the other obvious use. * Formatting. * Add missed refactor change. * Add issue to TODO comment. * Remove TODOs that don't seem necessary. * Add issue for TODO. * Add issue for TODO. * Remove dubious looking FP to int code that was ifdef'ed out. Doesn't look like a TODO is needed anymore. * Add issues for TODOs. * Update simd_op_check_sve2.cpp * Make a deep copy of each piece of test IR so that we can parallelize * Fix two clang-tidy warnings * Remove try/catch block from simd-op-check-sve2 * Don't try to run SVE2 code if vector_bits doesn't match host. * Add support for fcvtm/p, make scalars go through pattern matching too (#8151) * Don't do arm neon instruction selection on scalars This revealed a bug. FindIntrinsics was not enabled for scalars anyway, so it was semi-pointless. --------- Co-authored-by: Zalman Stern <zalman@macbook-pro.lan> Co-authored-by: Steven Johnson <srj@google.com> Co-authored-by: Andrew Adams <andrew.b.adams@gmail.com> 15 March 2024, 20:01:51 UTC

83616f2 Andrew Adams 13 March 2024, 00:00:49 UTC Fix three nits (#8137) 1) has_gpu_feature already includes Vulkan, so there's no need to check for it. 2) Use emplace(...) instead of insert(make_pair(...)) 3) Fixed a place that should be using a ScopedValue 13 March 2024, 00:00:49 UTC
4988ab5 Martijn Courteaux 12 March 2024, 23:58:14 UTC Feature: mark a Func as no_profiling, to prevent injection of profiling. (2nd implementation) (#8143) * Small feature to allow you to specify that a (typically small inner loop) Func should not be profiled. * Simplified the tuple name handling. * Optimize tuple name normalization in Profiling.cpp * Clang-format * Feedback on Function already being a pointer.

bf0d611 Andrew Adams 12 March 2024, 16:49:26 UTC Rewrite the pass that adds mutexes for atomic nodes (#8105) * Avoid redundant scope lookups This pattern has been bugging me for a long time: ``` if (scope.contains(key)) { Foo f = scope.get(key); } ``` This redundantly looks up the key in the scope twice. I've finally gotten around to fixing it. I've introduced a find method that either returns a const pointer to the value, if it exists, or null. It also searches any containing scopes, which are held by const pointer, so the method has to return a const pointer. ``` if (const Foo *f = scope.find(key)) { } ``` For cases where you want to get and then mutate, I added shallow_find, which doesn't search enclosing scopes, but returns a mutable pointer. We were also doing redundant scope lookups in ScopedBinding. We stored the key in the helper object, and then did a pop on that key in the ScopedBinding destructor. This commit changes Scope so that Scope::push returns an opaque token that you can pass to Scope::pop to have it remove that element without doing a fresh lookup. ScopedBinding now uses this. Under the hood it's just an iterator on the underlying map (map iterators are not invalidated on inserting or removing other stuff). The net effect is to speed up local laplacian lowering by about 5% I also considered making it look more like an stl class, and having find return an iterator, but it doesn't really work. The iterator it returns might point to an entry in an enclosing scope, in which case you can't compare it to the .end() method of the scope you have. Scopes are different enough from maps that the interface really needs to be distinct. * Pacify clang-tidy * Rewrite the pass that injects mutexes to support atomics For O(n) nested allocate nodes, this pass was quadratic in n, even if there was no use of atomics. This commit rewrites it to use a linear-time algorithm, and skips it entirely after the first validation pass if there aren't any atomic nodes. It also needlessly used IRGraphMutators, which slowed things down, didn't handle LargeBuffers (could overflow in the allocation), incorrectly thought every producer/consumer node was associated with an output buffer, and didn't print the realization name when printing the atomic node (the body of an atomic node is only atomic w.r.t. a specific realization). I noticed all this because it stuck out in a profile. For resnet 50, the rewrite that changed to a linear algorithm took this stage from 185ms down to 6.7ms, and then skipping it entirely when it doesn't find any atomic nodes added 1.5 for the single IRVisitor check. For local laplacian with 100 pyramid levels (which contains many nested allocate nodes due to a large number of skip connections), the times are 5846 ms -> 16 ms -> 4.6 ms This is built on top of #8103 * Fix unintentional mutation of interval in scope --------- Co-authored-by: Steven Johnson <srj@google.com> 12 March 2024, 16:49:26 UTC

009fe7a Andrew Adams 08 March 2024, 16:50:20 UTC Handle loads of broadcasts in FlattenNestedRamps (#8139) With sufficiently perverse schedules, it's possible to end up with a load of a broadcast index (rather than a broadcast of a scalar load). This made FlattenNestedRamps divide by zero. Unfortunately this happened in a complex production pipeline, so I'm not entirely sure how to reproduce it. For that pipeline, this change fixes it and produces correct output. 08 March 2024, 16:50:20 UTC

The latter is only available in v65 or later. This commit ensures compatibility with v65 and later versions. * Minor fix to address the issue. --------- Co-authored-by: Steven Johnson <srj@google.com> 06 March 2024, 21:40:00 UTC

05ae15a Andrew Adams 05 March 2024, 17:50:19 UTC Make gpu thread and block for loop names opaque (#8133) This is one of our largest remaining type of magic name. These were explicitly constructed in lots of places and then explicitly checked for with ends_with in lots of places. This PR makes the names opaque. Only CanonicalizeGPUVars.cpp knows what they are, and they don't have to be a single fixed thing as long as they're consistent within a process. Also reduced the number of GPU dimensions to three more uniformly. We were already asserting this, but there was lots of dead code in lowering passes after gpu loop validation that allowed for four. Also fixed a bug I found in is_block_uniform. It didn't consider that the dependence on a gpu thread variable in a load index could be because a let variable encountered depends on a gpu thread variable. 05 March 2024, 17:50:19 UTC

Scopes are different enough from maps that the interface really needs to be distinct. * Pacify clang-tidy * Fix unintentional mutation of interval in scope * Fix accidental Scope::get * Rewrite the skip stages lowering pass Skip stages was slow due to crappy computational complexity (quadratic?) I reworked it into a two-pass linear-time algorithm. The first part remembers which pieces of IR are actually relevant to the task, and the second pass performs the task using a bounds-inference-like algorithm. On main resnet50 spends 519 ms in this pass. This commit reduces it to 40 ms. Local laplacian with 100 pyramid levels spends 7.4 seconds in this pass. This commit reduces it to ~3 ms. This commit also moves the cache store for memoized Funcs into the produce node, instead of at the top of the consume node, because it naturally places it inside a condition you inject into the produce node. * clang-tidy fixes * Fix skip stages interaction with compute_with * Unify let visitors, and use fewer stack frames for them * Fix accidental leakage of .used into .loaded * Visit the bodies of uninteresting let chains * Another used -> loaded * Fix hoist_storage not handling condition correctly. --------- Co-authored-by: Steven Johnson <srj@google.com> 27 February 2024, 01:56:59 UTC

aae84f6 Andrew Adams 26 February 2024, 17:56:17 UTC Use a caching version of stmt_uses_vars in TightenProducerConsumer nodes (#8102) We were making a very large number stmt_uses_vars queries that covered the same sub-stmts. I solved it by adding a cache. Speeds up local laplacian lowering by 10% by basically removing this pass from the profile. Also a drive-by typo fix in Lower.cpp 26 February 2024, 17:56:17 UTC

ef31bf9 Andrew Adams 22 February 2024, 17:13:43 UTC Do less redundant work in UnpackBuffers (#8104) We were redundantly creating a handle Variable every time we encountered something like foo.stride.0, instead of just the first time we encounter a Variable that refers to an input Parameter/Buffer. Speeds up this already-fast lowering pass by 10% or so. No measurable impact on total lowering time. 22 February 2024, 17:13:43 UTC

4fc1e57 Zalman Stern 16 February 2024, 21:58:23 UTC Fix an issue where the Halide compiler hits an internal error for bool types in widening intrinsics. (#8099) * Fix an issue where the Halide compiler hits an internal error when bool types are used with e.g. widening_mul. This situation did not arise from user code doing this directly, but rather through some chain o lowering with float16 types. The test cases added to correctness_intrinsics target the issue directly and do fail without the fix. I did not add broader coverage for bool types and intrinsics as it would require more thinking. Most of them overflow for the true/true case and thus are of questionable use, however widening operations cannot overflow... Certainly we could define the language to forbid this, but currently the frontend does not do so. As indicated above, the use case driving this was not using bool arithmetic to begin with. * Formatting. 16 February 2024, 21:58:23 UTC

2855ca3 Andrew Adams 15 February 2024, 17:06:36 UTC Strip asserts right at the end of lowering (#8094) The simplifier exploits asserts to make simplification. When compiling with NoAsserts, certain assertions aren't ever introduced, which means that the simplifier can't exploit certain things that we know to be true. Mostly this has a negative effect on code size. E.g. tail cases get generated even though they are actually dead code. This PR keeps all the assertions right until the end of lowering, when it strips them in a dedicated pass. This reduces object file size for a large production blob of Halide code by ~10%, without measurably affecting runtime. 15 February 2024, 17:06:36 UTC

ada6345 Andrew Adams 12 February 2024, 18:10:00 UTC Fix rfactor adding too many pure loops (#8086) When you rfactor an update definition, the new update definition must use all the pure vars of the Func, even though the one you're rfactoring may not have used them all. We also want to preserve any scheduling already done to the pure vars, so we want to preserve the dims list and splits list from the original definition. The code accounted for this by checking the dims list for any missing pure vars and adding them at the end (just before Var::outermost()), but this didn't account for the fact that they may no longer exist in the dims list due to splits that didn't reuse the outer name. In these circumstances we could end up with too many pure loops. E.g. if x has been split into xo and xi, then the code was adding a loop for x even though there were already loops for xo and xi, which of course produces garbage output. This PR instead just checks which pure vars are actually used in the update definition up front, and then uses that to tell which ones should be added. Fixes #7890 12 February 2024, 18:10:00 UTC
9c3615b Andrew Adams 11 February 2024, 18:41:01 UTC Add checks to prevent people from using negative split factors (#8076) * Add checks to prevent people from using negative split factors Our analysis passes assume that loop maxes are greater than loop mins, so negative split factors cause sufficient havoc that not even output bounds queries are safe. These are therefore checked on pipeline entry. This is a new way for output bounds queries to throw errors (in addition to the buffer pointers themselves being null, and maybe some buffer constraints). Testing this, I realized these errors were getting thrown twice, because the output buffer bounds query in Pipeline::realize was built around two recursive calls to realize, and both were calling the custom error handler. In addition to reporting errors in this class twice, this implies several other inefficiencies, e.g. jit call args were being prepped twice. I reworked it to be built around two calls to call_jit_code instead.

de8e39d Steven Johnson 09 February 2024, 16:55:00 UTC Bump serialization version to 18.0.0 (#8080) * Bump serialization version to 18.0.0 As a matter of policy, we should probably bump the version of the serialization format for every version of Halide -- even if changes are minimal-to-nonexistent -- to reinforce the fact that this isn't intended in any way as a long-term archival format.

Checking them in ScheduleFunctions was incorrect because it didn't consider update definitions and specializations. Checking them in FuseGPUThreadLoops was too late, because the Var names have gone (they've been renamed to things like __thread_id_x). Furthermore, some problems were internal errors or runtime errors when they should have been user errors. We allowed 4d thread and block dimensions, but then hit an internal error. This PR centralizes checking of GPU loop structure in CanonicalizeGPUVars and adds more helpful error messages that print the problematic loop structure. E.g: ``` Error: GPU thread loop over f$8.s0.v0 is inside three other GPU thread loops. The maximum number of nested GPU thread loops is 3. The loop nest is: compute_at for g$8: for g$8.s0.v7: for g$8.s0.v6: for g$8.s0.v5: for g$8.s0.v4: gpu_block g$8.s0.v3: gpu_block g$8.s0.v2: gpu_thread g$8.s0.v1: gpu_thread g$8.s0.v0: store_at for f$8: compute_at for f$8: gpu_thread f$8.s0.v1: gpu_thread f$8.s0.v0: ``` Fixes the bug found in #7946 * Delete dead code * Actually clear the ostringstream 07 February 2024, 17:49:06 UTC

Initing them from different locations is enough to outsmart the compiler.

45d7850 Andrew Adams 26 January 2024, 20:01:41 UTC Track whether or not let expressions failed to solve in solver (#7982) * Track whether or not let expressions failed to solve in solver After mutating an expression, the solver needs to know two things: 1) Did the expression contain the variable we're solving for 2) Was the expression successfully "solved" for the variable. I.e. the variable only appears once in the leftmost position. We need to know this to know property 1 of any subexpressions (i.e. does the right child of the expression contain the variable). This drives what transformations we do in ways that are guaranteed to terminate and not take exponential time. We were tracking property 1 through lets but not property 2, and this meant we were doing unhelpful transformations in some cases. I found a case in the wild where this made a pipeline take > 1 hour to compile (I killed it after an hour). It may have been in an infinite transformation loop, or it might have just been exponential. Not sure. * Remove surplus comma * Fix use of uninitialized value that could cause bad transformation 26 January 2024, 20:01:41 UTC

When faced with the expression: min(ramp(x8(a), x8(b), 5), x40(27)) It panicked, because on the left hand side it reduced the bounds to x8(a) ... x8(a) + x8(b) * 4, and on the right hand side it reduced the bounds to 27. It then attempted to take a min of mismatched types. In general we can't assume that binary operators on nested vectors have the same nesting structure on both sides, so I just rewrote it to reduce directly to a scalar.
