Makarov <vmakarov@redhat.com> Date: Thu Jan 21 17:27:01 2021 -0500 [PR98777] LRA: Use preliminary created pseudo for in LRA elimination subpass LRA did not extend ira_reg_equiv after generation of a pseudo in eliminate_regs_in_insn which might results in LRA crash. It is better not to extend ira_reg_equiv but to use preliminary generated pseudo. The patch implements it. gcc/ChangeLog: PR rtl-optimization/98777 * lra-int.h (lra_pmode_pseudo): New extern. * lra.c (lra_pmode_pseudo): New global. (lra): Set it up. * lra-eliminations.c (eliminate_regs_in_insn): Use it. gcc/testsuite/ChangeLog: PR rtl-optimization/98777 * gcc.target/riscv/pr98777.c: New.
