Subject: [PATCH] powerpc/Makefiles: Fix clang/llvm build
Date: Tue, 21 Aug 2018 11:02:03 +1000 [thread overview]
Message-ID: <20180821010203.23213-1-anton@ozlabs.org> (raw)
From: Anton Blanchard <anton@samba.org>
Commit 15a3204d24a3 ("powerpc/64s: Set assembler machine type to POWER4")
passes -mpower4 to the assembler. We have more recent instructions in our
assembly files, but gas permits them. The clang/llvm integrated assembler
is more strict, and we get a build failure.
Fix this by calling the assembler with -mcpu=power8
