RA: Constrain class of pic offset table pseudo to general regs
On some targets an integer pseudo can be assigned to a FP reg. For
pic offset table pseudo it means we will reload the pseudo in this
case and, as a consequence, memory containing the pseudo might be
recognized as wrong one. The patch fix this problem.
PR target/109541
gcc/ChangeLog:
* ira-costs.cc: (find_costs_and_classes): Constrain classes of pic
offset table pseudo to a general reg subset.
gcc/testsuite/ChangeLog:
* gcc.target/sparc/pr109541.c: New.
