Subject: [PATCH 4/8] MIPS: traps: Use GPR number macros
Date: Fri, 09 Feb 2024 18:07:50 +0000 [thread overview]
Message-ID: <20240209-regname-v1-4-2125efa016ef@flygoat.com> (raw)
In-Reply-To: <20240209-regname-v1-0-2125efa016ef@flygoat.com>
Use GPR number macros in uasm code generation parts to
reduce code duplication.
No functional change.
