PowerPC gcc aligns char arrays to a word which results in the test
failing since it expects a char alignment. As the test already uses
gcc attributes to assign variables to sections, we may as well use an
attribute to align too.
* testsuite/plugin_layout_with_alignment.c: Explicitly align all
variables.
G++ in GCC 4.2 silently ignores
---
__attribute__ ((section(".rodata.v1_a2")))
const short rodata_item1 = 101;
---
which leads to plugin_layout_with_alignment test failure with
Expected 12 sections, found 8 sections
since 4 .rodata sections are missing. As a workaround, this patch
changes plugin_layout_with_alignment test from C++ to C.
* testsuite/plugin_layout_with_alignment.cc: Renamed to ..
* testsuite/plugin_layout_with_alignment.c: This.
* testsuite/Makefile.am (plugin_layout_with_alignment.o): Updated.
(plugin_layout_with_alignment): Likewise.
* testsuite/Makefile.in: Regenerated.
