Comment 1 Dominique d'Humieres 2012-03-30 21:15:17 UTC 
Confirmed on powerpc-apple-darwin9. Compiling the preprocessed code with '-O2 -m64' gives the ICE, but not when using '-O2' nor '-O1 -m64'.

Comment 3 Dominique d'Humieres 2012-03-31 15:16:18 UTC 
The error is the same as in pr52808.
Comment 4 David Edelsohn 2012-04-01 23:05:07 UTC 
powerpc-aix as well.
Comment 5 Dominique d'Humieres 2012-04-03 09:07:46 UTC 
I successfully bootstrapped revision 186090 on powerpc-apple-darwin9. From http://gcc.gnu.org/ml/gcc-testresults/2012-04/msg00234.html it seems also fixed for powerpc64-unknown-linux-gnu. So this PR could probably closed as fixed.
Comment 6 Richard Biener 2012-04-03 09:41:54 UTC 
Fixed then.
