gcc/ChangeLog:
* config.gcc: add loongarch-d.o to d_target_objs for LoongArch
architecture.
gcc/config/ChangeLog:
* loongarch/loongarch-d.cc
(loongarch_d_target_versions): add interface function to define builtin
D versions for LoongArch architecture.
(loongarch_d_handle_target_float_abi): add interface function to define
builtin D traits for LoongArch architecture.
(loongarch_d_register_target_info): add interface function to register
loongarch_d_handle_target_float_abi function.
* loongarch/loongarch-d.h:
(loongarch_d_target_versions): add function prototype.
(loongarch_d_register_target_info): Likewise.
* loongarch/t-loongarch: add object target for loongarch-d.cc.
libphobos/ChangeLog:
* configure.tgt: enable libphobos for LoongArch architecture.
* configure: Regenerate.
* libdruntime/gcc/sections/elf.d: add TLS_DTV_OFFSET constant for
LoongArch64.
* libdruntime/gcc/unwind/generic.d: add __aligned__ constant for
LoongArch64.
* libdruntime/Makefile.in: Regenerate.
