--- Comment #6 from Ian Lance Taylor <ian at airs dot com> 2011-02-04 00:08:42 UTC --- The old bug was about bad code generation, and that was fixed. I don't think it needs to be reopened. I can not find any discussion about fixing this issue in any way other than forbidding it. I have no problem with forbidding clobbering fixed registers. That is a related but distinct issue. I do not think it is helpful to force people to consider pic vs. non-pic issues. They can still consider them if they choose, but I do not think it is helpful to force them.
