Bug ID: 58429
Summary: _Decimal64 support is broken on powerpc64 with the
mode32 ABI (-m32 -mpowerpc64)
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: vincent-gcc at vinc17 dot net
On gcc110.fsffrance.org:
$ cat ./decimal64.c
#include <stdio.h>
int main(void)
{
_Decimal64 x = 1;
if (x != x)
{
printf ("Error!\n");
return 1;
}
else
{
printf ("OK\n");
return 0;
}
}
$ gcc -Wall -std=gnu99 -m32 -mpowerpc64 decimal64.c -o decimal64 -O
$ ./decimal64
OK
$ gcc -Wall -std=gnu99 -m32 -mpowerpc64 decimal64.c -o decimal64
$ ./decimal64
Error!
(The lack of error with -O is due to obvious optimization; a "volatile" on the
variable makes the error appear in every case.)
The problem doesn't appear with -m32 alone or -mpowerpc64 alone. Both are
needed to make it appear.
$ gcc --version

This is most likely a dup of bug 27619 which was a bug in binutils.
