Allows back-end optimizations to use alias type information.
#pragma c9x_alias_by_type on | off | reset
When this pragma is on, the compiler's back-end optimizations take advantage of type information gathered during alias analysis. Turn this pragma on if your source code follows the type rules specified by the ISO/IEC 9899-1999 C standard ("C99"), section 6.5.
Turn this pragma off if your source code violates type rules. The information collected from source code that violates these rules might lead the compiler to apply its optimizations incorrectly.
This pragma does not have a corresponding IDE panel setting.
