xlc16 for jdk11 AIX build

[Baesken, Matthias]

Hello,  we recently moved  the  jdk/jdk   AIX-build   to xlc16 (new-style xlclang) .
See for instance  change :   8224214: [AIX] Remove support for legacy xlc compiler
that removed the support for older xlc compilers.

We at SAP  currently think about  moving  the jdk11  AIX - build  to  xlc16  .
There are  two  options when building with xlc16  :

  1.  using  the   xlc16 legacy (non-clang) compiler .
This works already ,   and is probably  more compatible  for people using e.g. xlc12 / xlc13 ;


  1.  using  xlc16/xlclang
This would  need  the downporting of more changes to 11 and is probably  less  (not?) compatible  for people  still using older xlc  versions .


What is your opinion ?
What are the xlc versions  people use currently for building  jdk11 on AIX  ?

Best regards, Matthias
