Subject: [PATCH v2 1/1] gcc/d: add LoongArch64 support for D frontend
Date: Sun, 24 Sep 2023 15:40:33 -0600	[thread overview]
Message-ID: <20230924214038.30221-2-liushuyu011@gmail.com> (raw)
In-Reply-To: <20230924214038.30221-1-liushuyu011@gmail.com>

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.
