ira.c (update_equiv_regs): Only call set_paradoxical_subreg for non-debug insns.
gcc/
* ira.c (update_equiv_regs): Only call set_paradoxical_subreg
for non-debug insns.
* lra.c (new_insn_reg): Take the containing insn as a parameter.
Only modify lra_reg_info[].biggest_mode if it's non-debug insn.
(collect_non_operand_hard_regs, add_regs_to_insn_regno_info): Update
accordingly.
gcc/testsuite/
* g++.dg/debug/ra1.C: New test.
