Quick summary

When I trying to build and package Play! for linux on riscv64 architecture, I got No SIMD instrinsics available for this platform.

System Details

• Operating system: Arch Linux risc-v port
• Hardware: rv64gc target
• Version of Play!: Commit ca98a3ca28a863469861400da2b220aa45cb1243

Issue Details

SIMD checking might should be in runtime, but not compile?

As yes, we could probably lower it down to a warning and have fallbacks for code that use the intrinsics (I think GSH_OpenGL is gonna be a problem for example).

Though unfortunately, even if you get it to compile, you won't get much further since we don't have a JIT for RISC-V.

Does that mean Play haven't support RISC-V?

Not as of now.
