Subject: [PATCH v4 05/12] RISC-V: add auipc elements to parse_asm header
Date: Wed, 7 Dec 2022 19:08:14 +0100 [thread overview]
Message-ID: <20221207180821.2479987-6-heiko@sntech.de> (raw)
In-Reply-To: <20221207180821.2479987-1-heiko@sntech.de>
From: Heiko Stuebner <heiko.stuebner@vrull.eu>
Instruction parsing should not be done in individual code, but instead
supported by central
Right now kgdb and kprobes parse instructions and at least kprobes (and
the upcoming auipc+jalr alternative fixer-function) need the auipc
instruction.
