            Bug ID: 20447
           Summary: Integrated arm assembler doesn't understand .fpu neon
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: ARM
          Assignee: unassignedbugs at nondot.org
          Reporter: nicolasweber at gmx.de
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

This works:

$ cat test.S
   .fpu neon
  VAND d3, d5, d5

$ ~/src/llvm-build/bin/clang -target arm-linux-androideabi  -c  test.S
-Btoolchains/arm-linux-androideabi-4.6/ -no-integrated-as  

This doesn't:

$ ~/src/llvm-build/bin/clang -target arm-linux-androideabi  -c  test.S
test.S:2:3: error: instruction requires: NEON
  VAND d3, d5, d5

Used by various arm assembly routines (e.g. in opus and openssl/boringssl).
