re PR rtl-optimization/59466 (Slow code generation by LRA for memory addresses on PPC)
2013-12-16 Vladimir Makarov <vmakarov@redhat.com>
PR rtl-optimization/59466
* emit-rtl.c (change_address_1): Don't validate address for LRA.
* recog.c (general_operand): Accept any memory for LRA.
* lra.c (lra_set_insn_recog_data): Add an assert.
