This is to remove macros {FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE defines in rs6000 port, and add new port specific hook implementation rs6000_c_mode_for_floating_type. gcc/ChangeLog: * config/rs6000/rs6000.cc (TARGET_C_MODE_FOR_FLOATING_TYPE): New macro. (rs6000_c_mode_for_floating_type): New function. * config/rs6000/rs6000.h (FLOAT_TYPE_SIZE): Remove. (DOUBLE_TYPE_SIZE): Likewise. (LONG_DOUBLE_TYPE_SIZE): Likewise. --- gcc/config/rs6000/rs6000.cc | 16 ++++++++++++++++ gcc/config/rs6000/rs6000.h | 14 -------------- 2 files changed, 16 insertions(+), 14 deletions(-)
