Antonio Maiorano	b293f51f83	Implement FXC workaround for vector access in loops resulting in failed loop unrolling When indexing into vectors in a loop, FXC sometimes fails to determine the max number of iterations when attempting to unroll the loop, resulting in "error X3511: forced to unroll loop, but unrolling failed.". We work around this by calling a function that sets the input value at the input index into an inout vector. This seems to nudge FXC enough for it to determine the number of loop iterations to unroll.

Implement FXC workaround for vector access in loops resulting in failed loop unrolling

When indexing into vectors in a loop, FXC sometimes fails to determine
the max number of iterations when attempting to unroll the loop,
resulting in "error X3511: forced to unroll loop, but unrolling
failed.". We work around this by calling a function that sets the input
value at the input index into an inout vector. This seems to nudge FXC
enough for it to determine the number of loop iterations to unroll.
