Hello,<br>
<br>
SystemZ prefers to align all global variables to two bytes, which is<br>
implemented by setting the TargetInfo member MinGlobalAlign.<br>
<br>
However, for compatibility with existing compilers this should *not*<br>
change the ABI alignment value as retrieved via __alignof__, which<br>
it currently does.<br>
<br>
This patch fixes the issue by having ASTContext::getDeclAlign ignore<br>
the MinGlobalAlign setting in the ForAlignof case.<br>
<br>
Since SystemZ is the only platform setting MinGlobalAlign, this should<br>
cause no change for any other target.<br>
<br>
(See attached file: clang-align-global)<br>
<br>
<br>
Mit freundlichen Gruessen / Best Regards<br>
<br>
