clang -E

arch/x86/crypto/aes-x86_64-asm_64.S:190: Error: invalid character '%' in
mnemonic

clang -MD -MF arch/x86/crypto/.aes-x86_64-asm_64.o.d  -nostdinc -isystem
include -Iinclude  -I/home/edwin/builds/linux-2.6/arch/x86/include -include
include/linux/autoconf.h -D__KERNEL__ -D__ASSEMBLY__ -m64 -DCONFIG_AS_CFI=1
-DCONFIG_AS_CFI_SIGNAL_FRAME=1 -Iarch/x86/include/asm/mach-default    -DMODULE
-c -o arch/x86/crypto/aes-x86_64-asm_64.o arch/x86/crypto/aes-x86_64-asm_64.S
-E -o x.s

gcc -MD -MF arch/x86/crypto/.aes-x86_64-asm_64.o.d  -nostdinc -isystem
/usr/lib/gcc/x86_64-linux-gnu/4.3.3/include -Iinclude 
-I/home/edwin/builds/linux-2.6/arch/x86/include -include
include/linux/autoconf.h -D__KERNEL__ -D__ASSEMBLY__ -m64 -DCONFIG_AS_CFI=1
-DCONFIG_AS_CFI_SIGNAL_FRAME=1 -Iarch/x86/include/asm/mach-default    -DMODULE 
arch/x86/crypto/aes-x86_64-asm_64.S -E -o y.s

clang's x.s is not compilable by gcc -c, but gcc's y.s is compilable by clang.

I'm attaching preprocessed files, however clang's preprocessed file is invalid
in this case i think.
