Build arrays of constants if necessary. The HLSL compiler sometimes does relative addressing over an array of DEF'd constants, as a lookup table. We now consider what DEFs we can group into contiguous arrays, and if a relative address would touch it, we generate a proper array of the reasonable range. This seems to be clever; I'm hoping it's not TOO clever, though.
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:
