Feature: SSMD Control Flow Support

Controlflow support for SSMD packagemode:

Allows for constructs that alter controlflow for each ssmd record processed, in effect it will allow:

• if then else
• switch statements
• variable while and for loops

Designtime Compilation of script into native function pointers

Designtime transpiler for normal blastscript packages:

• no difference in performance between native c# and normally packaged blast script execution
• allows for simpler workflows dueue to not having a performance drawback by using script for known actions

Safe Managed Only compiler defines: no unsafe, fully managed

Safe Managed Only compiler defines, allow for managed mode compilation of blast through compiler defines.

• do not use burst
• do not use native memory
• do not use unsafe compilation
• allow full access to gameobjects through delegates

Compute Shader execution of controlflow free SSMD scripts

Execution of blast script on bitmapped data using compute shaders.

• extreme parallel performance in ssmd mode
• float only
• controlflow support: please request if wanted

SSMD: Full integer support

Full integer vector support for the SSMD packaging mode.

• Enables int, int2, int3, int4 in all operations for ssmd scripts
• Allows for mixing of integer and float datatypes in operations

Together with controlflow support this would allow all normal scripts to execute in ssmd mode given all external functions have a vectorized equivalent. In order for that to work the interpretors need more information about the registered external function signatures.

Managed Mode .NET: use of SSE4/AVX intrinsics (ssmd)

Use System.Numerics.Intrinsics when compiling outside unity for .net. While a burst/il2cpp toolchain is used to compile blast in unity with use of intrinsics for .net we need to do this manually for large sections of the code illegable for such optimizations.

• Add SSE4 & AVX2 Support to all array operations

Dueue to the nature of this optimization for windows mainly the ssmd interpretors will benifit as they work on large arrays of data.
