Subject: [PATCH] ARM: makefile: work around toolchain bug in recent versions of binutils
Date: Thu, 2 Aug 2012 13:23:26 +0100 [thread overview]
Message-ID: <1343910206-3684-1-git-send-email-will.deacon@arm.com> (raw)
Recent upstream versions of binutils fail to assembler compressed/head.S
when passed the -march=all option:
http://lists.gnu.org/archive/html/bug-binutils/2011-04/msg00162.html
The recommended workaround from the tools folks is not to pass the
option, and instead let the assembler deduce the CPU type based on the
features used by the code.
