This is to remove macros {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE defines in rx port, and add new port specific hook implementation rx_c_mode_for_floating_type. gcc/ChangeLog: * config/rx/rx.cc (rx_c_mode_for_floating_type): New function. (TARGET_C_MODE_FOR_FLOATING_TYPE): New macro. * config/rx/rx.h (FLOAT_TYPE_SIZE): Remove. (DOUBLE_TYPE_SIZE): Likewise. (LONG_DOUBLE_TYPE_SIZE): Likewise. --- gcc/config/rx/rx.cc | 15 +++++++++++++++ gcc/config/rx/rx.h | 4 ---- 2 files changed, 15 insertions(+), 4 deletions(-)
