1.5.2

[1.5.2] - 2021-04-14

Added

• Added support for having [return: MarshalAs(UnmanagedType.U1)] or [return: MarshalAs(UnmanagedType.I1)] on a bool return external function.

Removed

Changed

• In order to prevent conflicts with the main Unity process, Burst is now inactive in secondary Unity processes, including the asset import worker and out-of-process profiler. This means that in those secondary processes, code that would normally be Burst-compiled will now run under Mono. In a future release of Burst, we hope to lift this restriction and allow Burst-compiled code to run in secondary Unity processes.

Fixed

• Gracefully handle failing to find a particular assembly in the ILPP to prevent an ICE.
• Fixed a bug where if a user had Managed Stripping mode set to High, our injected Direct Call delegate would be accidentally stripped out.
• function calls using in modifiers on blittable structs where being treated as non blittable.
• Crash when extracting sequence point information for error reporting/debug information generation.
• The Direct Call injected delegate now has a unique suffix to avoid type-name clashes.
• Direct Call extension methods that only differ on argument types are now supported (previously Burst's AssemblyLoader would complain about multiple matches).
