Subject: [PATCH 7/7] MIPS: Remove unused PREF, PREFE & PREFX macros
Date: Mon, 15 Oct 2018 18:33:23 +0000 [thread overview]
Message-ID: <20181015183304.16782-8-paul.burton@mips.com> (raw)
In-Reply-To: <20181015183304.16782-1-paul.burton@mips.com>
asm/asm.h provides PREF(), PREFE() & PREFX() macros which are now
entirely unused. Delete the dead code.
