mintrinsic-promote, Qintrinsic-promote

Enables functions containing calls to intrinsics that require a specific CPU feature to have their target architecture automatically promoted to allow the required feature.

Syntax

Linux:
-mintrinsic-promote
Windows:
/Qintrinsic-promote
Arguments
None
Default
OFF
If this option is not specified and you call an intrinsic that requires a CPU feature not provided by the specified (or default) target processor, an error will be reported.
Description
This option enables functions containing calls to intrinsics that require a specific CPU feature to have their target architecture automatically promoted to allow the required feature.
All code within the function will be compiled with that target architecture, and the resulting code for such functions will not execute correctly on processors that do not support the required feature.
You are responsible for guarding the execution path at run time so that such functions are not dynamically reachable when the program is run on processors that do not support the required feature.
We recommend that you use __attribute__((target(<required target>))) to mark functions that are intended to be executed on specific target architectures instead of using this option. This attribute will provide significantly better compile time error checking.
