The powerpcspe backend has been deprecated in GCC 8 and removed during GCC 9
development. See corresponding mailing list threads[1,2,3] for details.

[Bug target/30259] ICE on valid code

[guenter at roeck-us dot net]

------- Comment #5 from guenter at roeck-us dot net  2007-02-04 16:40 -------
Problem is seen with 4.1.2 release candidate. Build is successful with proposed
patch for bug 30270 applied.

Not really my call to make, but it appears that this is neither P3 nor severity
"normal". Also, the status of "unconfirmed" appears to be inappropriate, as the
problem is easy to reproduce.
