  std (s->_stdout, 0x0008 | 0x0001, 1, s);

this C language (newlib/stdio/findfp.c) code generate following the assembler
code.

.LM46:
ldi:20  #736, r1
addnr4, r1

.LM47:
ldi:20  #740, r1

st  r2, @r1
.LM49:
ldi:32  #-740, r1   <-- illigal immidiate code
addnr1, r1
ldi:32  std, r9
ld  @r1, r4
.LVL14:

 gcc-4.3.4 (fr30-unknown-elf) generate following code. It can  execute
correctly.
