[Bug c++/28715] New: Attribute with section (".init_array") does't work under SPARC

[pastoor dot external at onespin-solutions dot com]

Normally the following code produces a new section with type SHT_INIT_ARRAY and
the function foo will be executed before the main routine starts. This is what
i got unter Linux-Systems. But under SPARC Systems the new section entry is of
type SHT_PROGBITS and won't execute before the main-routine.

static void foo()
{
;
};

void (*const init_array []) (void)
__attribute__ ((section (".init_array"), aligned (sizeof (void
* =
{
&foo
};

int main() {printf("main"); return 0;}

Okay, but when i execute the ELF under SPARC the init_array entries aren't
executed.
Loaders don't look in the sectionheadertable because all information they need
are in the programmheadertable.
I think the init_array isn't handled in the right way in the segments (for
SPARC) and thats because it is specified as SHT_PROGBIT in the
sectionheadertable, because PROGBITS aren't executed before the main-routine.
