AllocateHeapAt disabling on AIX

[Baesken, Matthias]

Hello,  we want to disable the globals-flag  AllocateHeapAt on AIX  .
It currently does not really work   on this platform,  and there is no  current plan to support it   .

My question :

Should I  just add a check to argument.cpp  ?
Or should I use  the   constraint  function  feature for this ?

E.g.  add   a  constraint function  to  globals.hpp  and then do something like this ?

JVMFlag::Error AllocateHeapAtConstraintFunc(ccstr value, bool verbose) {
#if defined(_AIX)
  return JVMFlag::VIOLATES_CONSTRAINT;
#endif
  return JVMFlag::SUCCESS;
}


To me the  current usages of the  constraint  functions do not look like they were intended for  platform-handling,  but for
   Checking  validity/sanity  of some flag values .


Thanks for your comments,  Matthias
