--- Comment #20 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Vladimir Makarov <vmaka...@gcc.gnu.org>: https://gcc.gnu.org/g:5568d224f2e179b8e91a90fa4fba10bd8a7f963d commit r13-7451-g5568d224f2e179b8e91a90fa4fba10bd8a7f963d Author: Vladimir N. Makarov <vmaka...@redhat.com> Date: Wed Jun 7 09:51:54 2023 -0400 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.
