I believe that FEAT_CPA is only [HasSVE, HasCPA] .
At least that is what I see here:
https://developer.arm.com/documentation/ddi0602/2023-09/SVE-Instructions/ADDPT--predicated---Add-checked-pointer-vectors--predicated--?lang=en
if !IsFeatureImplemented(FEAT_SVE) || !IsFeatureImplemented(FEAT_CPA) then
UNDEFINED;
And in bellow I see :
[CheckNonStreamingSVEEnabled](https://developer.arm.com/documentation/ddi0602/2023-09/Shared-Pseudocode/aarch64-functions-sve?lang=en#impl-aarch64.CheckNonStreamingSVEEnabled.0)();
I believe it means that these instructions are not available in streaming mode.
