[hjl@gnu-tools-1 gas]$ 

obj_elf_version pads note section to 4 byte alignment:

frag_align (2, 0, 0);

But it doesn't set section alignment to 4 bytes.

[Bug gas/22493] New: push {sp} fails on mcpu=cortex-a7

Bug ID: 22493
   Summary: push {sp} fails on mcpu=cortex-a7
   Product: binutils
   Version: 2.29
Status: UNCONFIRMED
  Severity: normal

Target: cortex-a7

The arm-none-eabi-as translates "push {sp}" wrong.
Instead of "stmfd sp!, {sp}" im getting "str sp, [sp, #-4]!".
This str is UNPREDICTABLE says ARMv7-A Refmanual (the cortex a7 throws an
undefined).
Because it uses writeback and Rn == Rt.
Im referencing to this doc:
http://liris.cnrs.fr/~mmrissa/lib/exe/fetch.php?media=armv7-a-r-manual.pdf (ARM
DDI 0406C.b (ID072512))
Chapter A8.8.205, page 676.

And im not getting a warning!
If im typing "str sp, [sp, #-4]!" manually I get a warning.
