Date: Sun, 04 May 2014 16:40:03 +0200 From: Riccardo Magliocchetti <riccardo.magliocchetti@...il.com> To: Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, Arnaldo Carvalho de Melo <acme@...stprotocols.net>, Ingo Molnar <mingo@...hat.com> Subject: perf not compiling on 64bit kernel 32bit userspace Hello, compiling perf on 32 bit userspace and 64 bit kernel fails on x86 because x86-64 assembly is compiled in: CC bench/mem-memcpy-x86-64-asm.o CC bench/mem-memset-x86-64-asm.o bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages: bench/../../../arch/x86/lib/memcpy_64.S:29: Error: bad register name `%rdi' Switching the check from RAW_ARCH to ARCH does the trick here on 3.14.2. If someone could please take care of fixing Linus' master and add this to the stable queue it would be much appreciated.
