Subject: [PATCH v2 08/17] target/mips: fpu: Demacro NMADD.<D|S|PS>
Date: Thu, 14 May 2020 21:20:38 +0200	[thread overview]
Message-ID: <20200514192047.5297-9-aleksandar.qemu.devel@gmail.com> (raw)
In-Reply-To: <20200514192047.5297-1-aleksandar.qemu.devel@gmail.com>

This is just a cosmetic change to enable tools like gcov, gdb,
callgrind, etc. to better display involved source code.
