diag-enable=power, Qdiag-enable:power

Controls whether diagnostics are enabled for possibly inefficient code that may affect power consumption on IA-32 and Intel® 64 architectures.

Syntax

Linux and macOS:
-diag-enable=power
-diag-disable=power
Windows:
/Qdiag-enable:power
/Qdiag-disable:power
Arguments
None
Default
-diag-disable=power
or
/Qdiag-disable:power
Power consumption diagnostics are disabled.
Description
This option controls whether diagnostics are enabled for possibly inefficient code that may affect power consumption on IA-32 and Intel® 64 architectures.
If you specify option
-diag-enable=power
(Linux* and
macOS*
) or
/Qdiag-enable:power
(Windows*), the compiler will detect various API calls with argument values in ranges known to be inefficient for power consumption. The diagnostic issued will point out the problem argument; for example, "power inefficient use of 'Sleep' with argument in range [0;10]".
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.
