Subject: [PATCH v5 02/22] MIPS: Export higher/highest relocation functions in uasm
Date: Tue, 12 Dec 2023 17:34:34 +0100 [thread overview]
Message-ID: <20231212163459.1923041-3-gregory.clement@bootlin.com> (raw)
In-Reply-To: <20231212163459.1923041-1-gregory.clement@bootlin.com>
From: Jiaxun Yang <jiaxun.yang@flygoat.com>
Export uasm_rel_{higher,highest} functions.
Those functions can be helpful in dealing with 64bit immediates.
