Consider the following C function, where EXPR is a macro defined with #define:

Below, we show the AVX2 code generated for different definitions of EXPR, where value x is held in %xmm0. All of them correspond to some useful operation on floating-point values. Identify what the operations are. Your answers will require you to understand the bit patterns of the constant words being retrieved from memory.
