- Subject: [GOLD] alignment test
- Authentication-results: sourceware.org; auth=none
PowerPC gcc aligns char arrays to a word which results in the test
failing since it expects a char alignment for *_item4 variables. As
the test already uses gcc attributes to assign variables to sections,
we may as well use an attribute to align too.
OK?
* testsuite/plugin_layout_with_alignment.c: Explicitly align all
variables.
