ansi-alias-check, Qansi-alias-check

Enables or disables the ansi-alias checker.

Syntax

Linux:
-ansi-alias-check
-no-ansi-alias-check
macOS:
-ansi-alias-check
-no-ansi-alias-check
Windows:
/Qansi-alias-check
/Qansi-alias-check-
Arguments
None
Default
-no-ansi-alias-check
or
/Qansi-alias-check-
The ansi-alias checker is disabled unless option
-ansi-alias-check
or
/Qansi-alias-check
has been specified.
Description
This option enables or disables the ansi-alias checker. The ansi-alias checker checks the source code for potential violations of ANSI aliasing rules and disables unsafe optimizations related to the code for those statements that are identified as potential violations.
You can use option
–Wstrict-aliasing
to identify potential violations.
If the
[Q]ansi-alias
option has been specified, the ansi-alias checker is enabled by default. You can use the negative form of the option (see Syntax above) to disable the checker.
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.
