Subject: [PATCH v1 1/3] LoongArch: Define relocation types added in ABI v2.10
Date:   Tue, 26 Sep 2023 16:10:50 +0800
Message-Id: <1695715852-15902-2-git-send-email-yangtiezhu@loongson.cn>
In-Reply-To: <1695715852-15902-1-git-send-email-yangtiezhu@loongson.cn>
References: <1695715852-15902-1-git-send-email-yangtiezhu@loongson.cn>
Precedence: bulk

The relocation types from 101 to 109 are used by GNU binutils >= 2.41,
add their definitions to use them in later patches.
