Subject: [PATCH 12/10] powerpc: unbreak DYNAMIC_DEBUG=y build with clang
Date: Fri, 26 Apr 2019 21:06:03 +0200 [thread overview]
Message-ID: <20190426190603.5982-2-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <20190426190603.5982-1-linux@rasmusvillemoes.dk>
Current versions of clang does not like the %c modifier in inline
assembly for targets other than x86, so any DYNAMIC_DEBUG=y build
fails on ppc64. A fix is likely to land in 9.0 (see
https://github.com/ClangBuiltLinux/linux/issues/456), but unbreak the
build for older versions.
Fixes: powerpc: select DYNAMIC_DEBUG_RELATIVE_POINTERS for PPC64
