Probably other places we could/should use this too. (Does C++20 have join/split strings in the std library yet?

4fc2a7d Steven Johnson 01 December 2023, 00:31:48 UTC Handle many more intrinsics in Bounds.cpp (#7823) * Handle many more intrinsics in Bounds.cpp This addresses many (but not all) of the `signed integer overflow` issues we're seeing in Google due to https://github.com/halide/Halide/pull/7814 -- a lot of the issues seems to be in code that uses intrinsics that had no handling in value bounds checking, so the bounds were naively large and overflowed. - Most of the intrinsics from FindIntrinsics.h weren't handled; now they all are (most by lowering to other IR, though the halving_add variants were modeled directly because the bitwise ops don't mesh well) - strict_float() is just a pass-through - round() is a best guess (basically, if bounds exist, expand by one as a worst-case) There are definitely others we should handle here... trunc/floor/ceil probably? * Fix round() and strict_float() handling * Update Bounds.cpp * Fixes? * trigger buildbots * Revert saturating_cast handling * Update Bounds.cpp --------- Co-authored-by: Andrew Adams <andrew.b.adams@gmail.com> 01 December 2023, 00:31:48 UTC

8c28a73 Andrew Adams 21 November 2023, 23:27:21 UTC Improve code size and compile time for local laplacian app (#7927) Improve code size and compile time for local laplacian and interpolate apps This reduces compile time for the manual local laplacian schedule from 4.9s to 2.2s, and reduces code size from 126k to 82k Most of the reduction comes from avoiding a pointless boundary condition in the output Func. A smaller amount comes from avoiding loop partitioning using RoundUp and Partition::Never. The Partition::Never calls are responsible for a 3% reduction in code size and compile times by themselves. This has basically no effect on runtime. It seems to reduce it very slightly, but it's in the noise. 21 November 2023, 23:27:21 UTC

(#7934) * Make sure all Halide arithmetic scalar types can be named from the Generator interface. Specifically adding 64-bit signed and unsigned integers and making sure float16 and bfloat16 are fully supported and documented. Add a simple test for all the type names. (Don't use float16 and bfloat16 in the arithmetic as they do not compile with the C++ backend. The name mapping should still be tested but the types passed do not seem to be checked as the values are not used.) 07 November 2023, 21:23:31 UTC

fffb8bd Andrew Adams 24 October 2023, 17:23:49 UTC Fix read-after-write hazard analysis in storage folding (#7910) Explicitly mark which loops get loop-carry-dependencies inserted by sliding window to assist storage folding. Storage folding needs to know about this so it doesn't try to fold in a way that invalidates these read-after-write dependencies. It currently tries to prove the absence of hazards with box_contains(box_provided, box_required), but this is sometimes incorrect because box_provided could be conservatively large, and the code it analyses might not actually provide (store to) all the required (loaded from) values. It's simpler for sliding window to just tell storage folding when it inserts loop-carry-dependencies, and this is most simply done directly in the IR itself. Fixes #7909 24 October 2023, 17:23:49 UTC
