Provide `long double' support for most i386 targets. * config/i386/tm-i386.h (TARGET_LONG_DOUBLE_FORMAT): Define as &floatformat_i387_ext. (TARGET_LONG_DOUBLE_BITS): Define as 96. (REGISTER_VIRTUAL_TYPE): Change type for FPU registers to `builtin_type_long_double'. (REGISTER_CONVERT_TO_VIRTUAL): Call i386_register_convert_to_virtual. (REGISTER_CONVERT_TO_RAW): Call i386_register_convert_to_raw. (i387_to_double, double_to_i387): Remove prototypes. (i386_extract_return_value): Change prototype to match definition in i386-tdep.c. * config/i386/tm-i386mk.h (TARGET_LONG_DOUBLE_FORMAT): #undef. (TARGET_LONG_DOUBLE_BITS): #undef. * config/i386/tm-linux.h (TARGET_LONG_DOUBLE_BIT): Remove. [HAVE_LONG_DOUBLE && HOST_I386] (LD_I387): Remove.

#define TARGET_LONG_DOUBLE_FORMAT TARGET_DOUBLE_FORMAT

#define TARGET_LONG_DOUBLE_BITS TARGET_DOUBLE_BITS
