[PATCH v2 02/17] target/mips: fpu: Demacro SUB.<D|S|PS>


From: Aleksandar Markovic
Subject: [PATCH v2 02/17] target/mips: fpu: Demacro SUB.<D|S|PS>
Date: Thu, 14 May 2020 21:20:32 +0200

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