Detailed Description

Registration of alternate projections, for tests whose device consumes a projection the build does not link. Declared in a test-only library, so no production target can register one.

Function Documentation

RegisterAlternateProjection()

void donner::gpu::shader::RegisterAlternateProjection	(	const CompiledShaderView &	linked,
		ShaderSourceKind	kind,
		const CompiledShaderView &	alternate )

Registers alternate as the view of linked's family for devices that consume kind.

Registration must happen before any device that consumes kind selects linked; the test-only alternates library does it from a static initializer. Registering the same alternate again is a no-op, and registering a different one for the same family and kind is a fatal error. Both views must outlive the process; artifact views do.

Parameters

linked	The family's linked artifact, identified by address.
kind	Source kind alternate carries.
alternate	The family's artifact for kind.
