[Bug gas/6993] New: Far call/jump aren't supported in Intel mode

[hjl dot tools at gmail dot com]

address@hidden tmp]$ cat jump.s
        call    *(%ebx)
        lcallw  *(%ebx)
        jmp     *(%ebx)
        ljmpw   *(%ebx)
address@hidden tmp]$ gcc -c -m32 jump.s
address@hidden tmp]$ objdump -dw -Mintel jump.o

jump.o:     file format elf32-i386


Disassembly of section .text:

00000000 <.text>:
   0:   ff 13                   call   DWORD PTR [ebx]
   2:   66 ff 1b                call   DWORD PTR [ebx]
   5:   ff 23                   jmp    DWORD PTR [ebx]
   7:   66 ff 2b                jmp    DWORD PTR [ebx]
address@hidden tmp]$

There are 2 problems:

1. Disassembler treats near/far call/jump the same.
2. Assembler doesn't support far call/jump. I don't think assembler supports
far address at all.
