This chapter explains how to use the -xalias_level option and several pragmas to enable the compiler to perform type-based alias analysis and optimizations. You use these extensions to express type-based information about the way pointers are used in your C program. The C compiler uses this information, in turn, for alias disambiguation of pointer-based memory references in your program.
