Shader Macros, check IOS CPU version?

Unity Engine
1

I have one shader that work perfect on many iOS devices, Snapdragon, Kirin and Mali.

but for some strange reason on A9 Chip the shader show bugs.

is there any macro like SHADER_API_METAL, for checking the Chip? I want to disable the feature only on A9 chipset.

regards
Fran

Hi!
No, there is no such macro.
You can, however, make two variants of your shader and use a keyword based on A9 to select a different variant.
