warning: "Function cannot return qualified void type 'volatile void'" about aes HOT 3 CLOSED

The VIA ACE code hasn't changed for many years now and I no longer have the kit that is necessary to test any changes that I might make in this. I am hence reluctant to make changes unless someone with VIA ACE kit is willing to test any changes that are made. I would expect that removing the volatile keyword would be all that is needed. If you are not using VIA ACE and simply want to remove the warnings, you can turn VIA ACE support off in aesopt.h.

On, nice suggestion! So I just need to change:

#if 1 && defined( VIA_ACE_POSSIBLE ) && !defined( USE_VIA_ACE_IF_PRESENT )
#  define USE_VIA_ACE_IF_PRESENT
#endif

to:

#if 0 && defined( VIA_ACE_POSSIBLE ) && !defined( USE_VIA_ACE_IF_PRESENT )
#  define USE_VIA_ACE_IF_PRESENT
#endif

It does solve my warning issue, but can't be done as a build setting (i.e. I have to edit the file).

The aesopt.h file (up to line 443) is intended to be edited by the user. As you can see if you look through it, this file contains a large number of user defined options that have to be set in order to obtain the optimum performance from the code.
