            Bug ID: 20247
           Summary: AVR/ARM align causes unnecessary padding of segment
           Product: binutils
           Version: 2.27 (HEAD)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: bg at nerilex dot org
  Target Milestone: ---

Created attachment 9334
  --> https://sourceware.org/bugzilla/attachment.cgi?id=9334&action=edit
assembly code to reproduce

Defining an alignment causes the corresponding section to get padded to a
multiple of the alignment value on some architectures.

I could see this behavior on:

 * arm
 * avr

It does not happen on x86_64.

I only tested the bss and data segment to be affected and both are.

Short code to reproduce is:

.balign 16
.skip 1
