Makarov <vmaka...@redhat.com> Date: Wed Mar 30 13:03:44 2022 -0400 [PR105032] LRA: modify loop condition to find reload insns for hard reg splitting When trying to split hard reg live range to assign hard reg to a reload pseudo, LRA searches for reload insns of the reload pseudo assuming a specific order of the reload insns. This order is violated if reload involved in inheritance transformation. In such case, the loop used for reload insn searching can become infinite. The patch fixes this. gcc/ChangeLog: PR middle-end/105032 * lra-assigns.cc (find_reload_regno_insns): Modify loop condition. gcc/testsuite/ChangeLog: PR middle-end/105032 * gcc.target/i386/pr105032.c: New.
