SPIR-V Built-In
CoalescedInputCountAMDX
Number of inputs coalesced for a coalescing node in a work graph
CoalescedInputCountAMDX
Decorating a variable with the CoalescedInputCountAMDX built-in
decoration will make that variable contain the number of node dispatches
that the implementation coalesced into the input for the current shader.
This variable will take a value in the range [1, arraySize), where
arraySize is the maximum size of the input payload array for the
shader.
