This time I think I collected all the constraints used by the program I'm trying
to compile. Thanks for fixing these bugs so far!

$ cat | llvm-as | llc
target endian = little
target pointersize = 32
target triple = "i686-pc-linux-gnu"
implementation
internal void %foo(){
        %tmp = call int asm sideeffect "push %ebp",
"={ax},a,b,c,d,S,D,ri,ir,~{dirflag},~{fpsr},~{flags},~{memory}"( int 0, int 0,
int 0, int 0, int 0, int 0, int 0, int 0 )
ret void
}
