Could OpenGL have feature change shaders code like bindlless textures ?

First interesting could GNC GPU change shaders code or piece of shader code, from texture or special (lets say ShaderBuffer) ?

How exactly GNC GPU change shaders ?


My proposition apply to OpenGL new feature, change shaders code from bindlless textures or from special ShaderBufferArray.


And when we draw one mesh 3 times (glDrawElementsInstanced ) , in main shader we do somthing like this  ShaderBufferArray([gl_InstanceID])


This mechanism will allow change on GPU shaders or  piece of shader code without CPU driver.


I know Shader Subroutine but dynamic subroutines slow and decrease FPS on 11%.



Very funny look ShaderBufferArray when we in Compute Shader could change on fly shader code in ShaderBufferArray !

Generated cool effects on fly.
