Detailed Description

Flatten header union into its individual element. All occurrences of the header union variables are replaced by the new header type variables. For ex: header_union U { Hdr1 h1; Hdr2 h2; }

struct Headers { Hdr1 h1; U u; }

is replaced by struct Headers { Hdr1 h1; Hdr1 u_h1; Hdr2 u_h2; }
