            Bug ID: 20254
           Summary: [avr] Relocations at end of a section are not
                    processed in the presence of alignment directives
           Product: binutils
           Version: 2.27 (HEAD)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: senthil.thecoder at gmail dot com
  Target Milestone: ---

This fails on binutils-2_26 branch. The fix to PR 20221 does not fix this.

$ cat test.s
.text
.global _start, dest
_start: 
  jmp dest
  .align        1
dest:
  nop
  rjmp dest


With 

$ avr-gcc -mmcu=atmega1280 -Os -mrelax test.s -nostartfiles
$ avr-objdump -S a.out

00000000 <__ctors_end>:
   0:   00 c0           rjmp    .+0             ; 0x2 <dest>

00000002 <dest>:
   2:   00 00           nop
   4:   00 c0           rjmp    .+0             ; 0x6 <_etext>


The rjmp at address 4 jumps to 0x6, instead of 0x2 (which is where dest is).
