Hi,

The .c and .bc files do match, there's no any foo.
Please try to compile it here: http://llvm.org/demo/index.cgi

; ModuleID = '/tmp/webcompile/_23568_0.bc'
target datalayout =
"e-p:32:32:32-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:32:64-f32:32:32-f64:32:64-v64:64:64-v128:128:128-a0:0:64-f80:32:32"
target triple = "i386-pc-linux-gnu"

define i32 @main() nounwind {
entry:
        %asmtmp.i = tail call i16 asm "movw\09%gs:${1:a}, ${0:w}",
"=r,ir,~{dirflag},~{fpsr},~{flags}"(i32 6) nounwind          ; <i16> [#uses=1]
        %0 = zext i16 %asmtmp.i to i32          ; <i32> [#uses=1]
        ret i32 %0
}

Both llvm-gcc and clang give analogous results.
