[Bug gas/254] New: Unnecessary long jumps

[daniel+redhatbugzilla at deadlock dot et dot tudelft dot nl]

If a label is declared global, gas generates long jumps to it, without any 
valid reason. 
 
I.e. suppose you feed gas this code: 
 
.text 
.globl target 
 
target: 
    nop 
    nop 
    jmp target 
 
 
... objdump --disassemble gives this output: 
 
Disassembly of section .text: 
 
00000000 <target>: 
   0:   90                      nop 
   1:   90                      nop 
   2:   e9 fc ff ff ff          jmp    3 <target+0x3> 
 
 
The GNU assembler has generated a long jump, even though it has all the 
information available to generate a short jump, the jump has a distance of 
just 2 bytes...
