What benefit is gained by doing this ?  I would guess that it is connected
with symbols changing type and/or visibility and/or protected status, but
it would be nice to know what you are hoping to achieve.

The code seems quite straightforward - but why limit the change to x86 
targets only ?  Are you expecting that it might break other targets ?

I assume that you have tested the patch with the x86 variants that you 
have changed - were there any regressions or changes ?

Would it be worth creating a test the demonstrates the value of the change.
If the test was not restricted to x86 targets then it could be used to
prompt a conversion of non-x86 targets as well.

Cheers
