           Summary: outb %al, (%dx) --> error: invalid operand for
                    instruction
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: X86
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: rdivacky at freebsd.org
                CC: llvmbugs at cs.uiuc.edu


witten delta# cat foo.s
outb %al, (%dx)
witten delta# as foo.s && echo success
success
witten delta# llvm-mc foo.s
    .section    __TEXT,__text,regular,pure_instructions
foo.s:1:11: error: invalid operand for instruction
outb %al, (%dx)
          ^

also, the diagnostics are pretty wrong too:

witten delta# cat foo.s                                                        
                                                                        outb
%al, (%dx)
outw %al, (%dx)
outl %al, (%dx)
witten delta# llvm-mc foo.s
    .section    __TEXT,__text,regular,pure_instructions
foo.s:1:11: error: invalid operand for instruction
outb %al, (%dx)
          ^
foo.s:3:6: error: invalid operand for instruction
outl %al, (%dx)
     ^

ie. two warnings, now I put some spaces there:


witten delta# cat foo.s
outb %al, (%dx)

outw %al, (%dx)

outl %al, (%dx)
witten delta# llvm-mc foo.s
    .section    __TEXT,__text,regular,pure_instructions
foo.s:1:11: error: invalid operand for instruction
outb %al, (%dx)
          ^
foo.s:3:6: error: invalid operand for instruction
outw %al, (%dx)
     ^
foo.s:5:6: error: invalid operand for instruction
outl %al, (%dx)

suddenly I have three warnings :)
