I.e. is it > certain that the patch for r122821 caused the bootstrap comparison failure? Yes, I did a regression search. See http://gcc.gnu.org/ml/gcc-testresults/2007-03/msg00674.html for r122820 linux results. I did a full bootstrap of C with r122820 on hppa2.0w-hp-hpux11.11. Didn't run testsuite. The same error occurs on both hpux and linux. Removal of the middle hunk of Richard's change does not fix the problem. I had thought the issue might be related to negative ashifts.
