106 \item[M2:] We modified the high-level intermediate representation to be based on the Graal compiler graph data structure. 106 \item[M2:] We modified the high-level intermediate representation to be based on the Graal compiler graph data structure.
107 \item[M3:] We have reimplemented and reenabled compiler optimizations in the Graal compiler that previously existed in C1X. 107 \item[M3:] We have reimplemented and reenabled compiler optimizations in the Graal compiler that previously existed in C1X.
