Subject: [PATCH v4 7/8] RISC-V: Make alias instructions aliases
Date: Fri, 18 Nov 2022 02:07:54 +0000 [thread overview]
Message-ID: <e5d45f2c8d1bb5b2d9adbfa117a3fc7d32afd6c9.1668737241.git.research_trasio@irq.a4lg.com> (raw)
In-Reply-To: <cover.1668737241.git.research_trasio@irq.a4lg.com>
This commit makes following alias instruction real aliases.
- scall (an alias of "ecall")
- fmv.x.s (an alias of "fmv.x.w")
- fmv.s.x (an alias of "fmv.w.x")
opcodes/ChangeLog:
* riscv-opc.c (riscv_opcodes): Make alias instructions aliases.
