As a partial mitigation for that issue, this PR adds a pass to hoist all prefetch instructions to the top of their loop. This is still a bit experimental; it definitely addresses the codegen issues we see, but makes the use of prefetch potentially less effective (since the hoisted prefetch may be too far from the eventual use to be effective). * appease clang-tidy * Avoid quadratic behavior * Use template instead of std::function * Require prefetch offset to be pure | 29 August 2021, 20:02:34 UTC |

| d507b9a | Steven Johnson | 23 August 2021, 21:46:26 UTC | Fix bug in prefetch() (#6225) In #6155, we incorrectly assume that we can qualify the 'from' prefetch var by just adding 'prefix'; this isn't true if (e.g.) there are any splits involved. Instead, we need to walk through the active loops to find a suitable match. In addition, if no match is found, we now fail with an error (rather than quietly doing something undefined), as the 'from' var is required to be from an active loop.

| 30040cd | Steven Johnson | 23 August 2021, 16:31:16 UTC | Prefetch cleanup (#6220) * Use std::move where appropriate * Prefetch cleanup This is (mostly) a cleanup pass to make the flow of Prefetch injection & lowering more obvious to the reader of the code (via commenting and minor code restructuring). Notable exception: the HVX backend processing of Call::prefetch (and relevant runtime code) was refactored to make it (IMHO) less janky.

(Note, this uses C++17 structured-binding syntax, which we previously weren't using in Halide. Objections?) This adds a shared utility method (well, two, thanks to VariadicVisitor) and plus in the usage in all the places that seemed obvious.

| b457d3c | Steven Johnson | 20 July 2021, 02:16:25 UTC | Add support for int16 output in Conv2D (#6145) This allows us to convert all (currently supported) FC ops into Conv2D ops. Remove all the FC-specific Halide and Op code. | 20 July 2021, 02:16:25 UTC |
| 9d1e1e3 | Steven Johnson | 20 July 2021, 00:33:52 UTC | [hannk] Rewrite FC in terms of Conv2D (#6144) * [hannk] Rewrite FC in terms of Conv2D FullyConnected is very similar to Conv2D, so rather than maintaining multiple similar implementations, let's translate a FullyConnected node into a Conv2D node (with some Reshape nodes as necessary). Note that we keep the old FC logic for int16 outputs, as Conv2D doesn't support those yet; if this PR is landed, a followup PR will add that ability to Conv2D, and the existing FC support will be removed entirely. | 20 July 2021, 00:33:52 UTC |

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 |
