--- Comment #17 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by hongtao Liu <liuho...@gcc.gnu.org>: https://gcc.gnu.org/g:4de7b010038933dd6ca96bf186ca49f243d0def6 commit r11-4202-g4de7b010038933dd6ca96bf186ca49f243d0def6 Author: liuhongt <hongtao....@intel.com> Date: Sat Sep 26 15:08:32 2020 +0800 Extend special_memory_constraint. For operand with special_memory_constraint, there could be a wrapper for memory_operand. Extract mem for operand for conditional judgement like MEM_P, also for record_address_regs. gcc/ChangeLog: PR target/87767 * ira-costs.c (record_operand_costs): Extract memory operand from recog_data.operand[i] for record_address_regs. (record_reg_classes): Extract memory operand from OP for conditional judgement MEM_P. * ira.c (ira_setup_alts): Ditto. * lra-constraints.c (extract_mem_from_operand): New function. (satisfies_memory_constraint_p): Extract memory operand from OP for decompose_mem_address, return false when there's no memory operand inside OP. (process_alt_operands): Remove MEM_P (op) since it would be judged in satisfies_memory_constraint_p. * recog.c (asm_operand_ok): Extract memory operand from OP for judgement of memory_operand (OP, VOIDmode). (constrain_operands): Don't unwrapper unary operator when there's memory operand inside. * rtl.h (extract_mem_from_operand): New decl.
