From a363b8f607ee9ba59bd7fea4a7af1a15745abf0a Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Fri, 28 Oct 2022 14:51:35 +0200 Subject: [PATCH v4 05/12] RISC-V: add auipc elements to parse_asm header 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.
