This is the newer double format, whereby the endian-ness of the doubles matches the endian-ness of the memory architecture. -mfpu=fpa This is when -mhard-float is specified. [It is not known if any XScale's have been made with hardware floating point support, but nevertheless this is what happens]. -mfpu=softfpa This is when -msoft-float is specified. This is the normal behavior of other arm configurations, which for backwards compatibility purposes default to supporting the old FPA format which was always big endian, regardless of the endian-ness of the memory system. */ #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \ %{mhard-float:-mfpu=fpa} \ %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}" #ifndef MULTILIB_DEFAULTS #define MULTILIB_DEFAULTS \ { "mlittle-endian", "mno-thumb-interwork", "marm", "msoft-float" } #endif
