Subject: [Bug target/23847] New: Darwin -mpowerpc64 complex ABI breakage
X-Bugzilla-Reason: CC
X-SW-Source: 2005-09/txt/msg01558.txt.bz2
List-Id: <gcc-bugs.sourceware.org>

Complex values are returned differently depending on -mpowerpc64.  For example
gcc.c-torture/execute/960512-1.c

__complex__
double f ()

In 32-bit mode, the complex value is returned in r3:r4,r5:r6.  In -mpowerpc64
mixed mode, the value is returned in r3,r4.  ABI breakage.  Oops.
