[cfe-dev] build error in git master

[kapamaroo]

Hello,

I get this error in debian unstable (arch amd64).

  COMPILE:   clang_linux/asan-i386/i386: /opt/llvm/projects/compiler-rt/lib/asan/asan_linux.cc
In file included from /opt/llvm/projects/compiler-rt/lib/asan/asan_linux.cc:27:
/usr/include/sys/syscall.h:25:10: fatal error: 'asm/unistd.h' file not found
#include <asm/unistd.h>
         ^
1 error generated.


configure options:

$ ../configure \
  --disable-assertions \
  --enable-optimized \
  --disable-debug-symbols \
  --disable-debug-runtime \
  --enable-targets=host-only

same with --enable-targets=all


installed packages:

linux-libc-dev    :/usr/include/x86_64-linux-gnu/asm/unistd.h
libc6-dev
libc6-dev-i386

Build fails after the following changes

r165096    "Build ASan runtime on Linux for both x86_64 and i386, same as we do with full compiler_rt and 
libprofile"
r165097    "Make sure 32-bit ASan runtime is available on 64-bit Linux platforms"

I cannot test it with another linux distribution, so maybe it is debian related or just me.
Maybe I need to enable multiarch support for i386. Anyone with the same problem?

Thanks, 

Maroudas Manolis
