Subject: [PATCH v2 01/10] MIPS: Export higher/highest relocation functions in uasm
Date: Fri, 27 Oct 2023 23:10:57 +0100 [thread overview]
Message-ID: <20231027221106.405666-2-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20231027221106.405666-1-jiaxun.yang@flygoat.com>
Export uasm_rel_{higher,highest} functions.
Those functions can be helpful in dealing with 64bit immediates.
