Restricting Optimizations

The following options restrict or preclude the compiler's ability to optimize your program:

-O0

Disables optimizations -O1, -O2, and-or -O3. Enables -fp option.

-mp

Restricts optimizations that cause some minor loss or gain of precision in floating-point arithmetic to maintain a declared level of precision and to ensure that floating-point arithmetic more nearly conforms to the ANSI and IEEE standards. See -mp option for more details.

-nolib_inline

Disables inline expansion of intrinsic functions.

For more information on ways to restrict optimization, see Interprocedural Optimizations with -Qoption.
