Many Fortran compilers perform code-generation optimizations to increase the speed of execution or to decrease the required amount of memory for the generated code. Although the behaviors of both the optimized and non-optimized programs fall within the language standard specification, different behaviors can occur in areas not covered by the language standard. Compiler optimization can influence floating-point numeric results.
The Intel® Fortran Compiler can perform optimizations to increase execution speed and to improve floating-point numerical consistency.
Floating-point consistency refers to obtaining results consistent with the IEEE binary floating-point standards. For more information, refer to the /fp:consistent option of fp-model.
