x86 displacement

[John S. Yates, Jr.]

I am optimizing a large hand crafted lexical analyze.
I was struck that in gcc 2.96 the size of x86 jump
displacements are not optimized.

 1725               .L247:
 1727               .LM167:
 1728 0778 C60720     movb $32, (%edi)
 1729 077b 47         incl %edi
 1730 077c 49         decl %ecx
 1731 077d 0F85F5FF   jne .L247  <<<<<<<<<<<<<<<<<
 1731      FFFF
 1732 0783 E902FDFF   jmp .L68
 1732      FF

Is this just a limitation of the assembler or is there
some flag I am missing?
