Hi All, AAarch64 back-end defines GENERAL_REGS and CORE_REGS with the same set of register. Is there any reason why we need this? target hooks like aarch64_register_move_cost doesnÂt handle CORE_REGS. In addition, IRA cost calculation also has logics like make common class biggest of best and alternate; this might get confused with this. Attached RFC patch removes it. regression tested for aarch64-none-linux-gnu on qemu-aarch64 with now new regression. Is this OK ? Thanks, Kugan gcc/ 2014-05-14 Kugan Vivekanandarajah <kuganv@linaro.org> * config/aarch64/aarch64.c (aarch64_regno_regclass) : Change CORE_REGS to GENERAL_REGS. (aarch64_secondary_reload) : LikeWise. (aarch64_class_max_nregs) : Remove CORE_REGS. * config/aarch64/aarch64.h (enum reg_class) : Remove CORE_REGS. (REG_CLASS_NAMES) : Likewise. (REG_CLASS_CONTENTS) : LikeWise. (INDEX_REG_CLASS) : Change CORE_REGS to GENERAL_REGS.
