strict-ansi

Tells the compiler to implement strict ANSI conformance dialect.

Syntax

Linux:
-strict-ansi
macOS:
-strict-ansi
Windows:
None
Arguments
None
Default
OFF
The compiler conforms to default standards.
Description
This option tells the compiler to implement strict ANSI conformance dialect. On Linux* systems, if you need to be compatible with gcc, use the
-ansi
option.
This option sets option
fmath-errno
, which tells the compiler to assume that the program tests errno after calls to math library functions. This restricts optimization because it causes the compiler to treat most math functions as having side effects.
Alternate Options
None

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
