Subject: [PATCH v2 2/4] LoongArch: define preprocessing macros "__loongarch_{arch,tune}"
Date: Wed, 30 Aug 2023 09:58:06 +0800	[thread overview]
Message-ID: <20230830015808.19870-3-yangyujie@loongson.cn> (raw)
In-Reply-To: <20230830015808.19870-1-yangyujie@loongson.cn>

These are exported according to the LoongArch Toolchain Conventions[1]
as a replacement of the obsolete "_LOONGARCH_{ARCH,TUNE}" macros,
which are expanded to strings representing the actual architecture
and microarchitecture of the target.

[1] currently relased at https://github.com/loongson/LoongArch-Documentation
    /blob/main/docs/LoongArch-toolchain-conventions-EN.adoc

gcc/ChangeLog:

	* config/loongarch/loongarch-c.cc: Export macros
	"__loongarch_{arch,tune}" in the preprocessor.
