📈 Improvements
- Exception strings no longer contain the entry-point name of the job/function-pointer that caused the throw. This change was required because the Burst compiler has to produce deterministic results from any given compile, which is fundamentally opposed to per-entry-point function derivations.
- Changed how exceptions throw types and messages are stored in our Burst binaries to reduce binary size.
- Upgraded Burst to use LLVM Version 11.0.1 by default, bringing the latest optimization improvements from the LLVM project.
🔧 Bug Fixes
- Fixed alignment issues associated with xxHash3 on ArmV7 (case 1288992)
- Fixed managed implementation of sub\_ss intrinsic
- Fixes DOTS Runtime JobProducer Bursting code to support JobProducers with multiple generic arguments, complex job wrapper and generic jobs.
- Fixed a bug that occurred when an explicitly laid out struct was used by a `dup` instruction, which caused an internal compiler error.
- Fixed a bug where if a user had defined multiple implicit or explicit casts, the compiler could resolve to the wrong cast.
- Fixed a bug where explicitly casting from an int to `IntPtr` would not sign extend the value.
- Fixed a bug where loading from a vector within a struct, that was got from a `NativeArray` using an indexer, would cause the compiler to crash.
- Fixed managed implementations of blend\_epi32 and mm256\_blend\_epi32 intrinsics on Mono
- Fixed an issue where Burst would erroneously error on `BurstCompile.CompileFunctionPointer ` calls when building for the DOTS Runtime.
- clang segmentation fault on iOS when member function debug information was emitted, it is disabled for this platform now.
- Intrinsics: Neon - fixed vget\_low and vget\_high producing suboptimal code
- Private `[BurstCompile]` methods no longer throw `MethodAccessException`
✨ Features
- Intrinsics: Neon - Added support for basic vld1 APIs
