Created attachment 28591

This generates (essentially) the same RTL as in non-PIC mode, so the generated

code should be correct if it is correct in non-PIC mode.



Tested only in LP64 mode though.

This regression is triggered by revision 188008:



http://gcc.gnu.org/ml/gcc-cvs/2012-05/msg00038.html



aka the un-sign-extension of sizetype constants.
