Define below macros accroding to LoongArch toolchain conventions [1].
__loongarch_grlen
__loongarch_frlen
__loongarch_lp64
__loongarch_hard_float
__loongarch_soft_float
__loongarch_single_float
__loongarch_double_float
Note:
1. __loongarch__ has been defined in earlier patch.
2. __loongarch_arch is not defined because I don't know how TargetInfo
can get the arch name specified by -march.
3. __loongarch_tune will be defined in future.
