[Bug gas/10853] New: Relocations for ppc assembler apply to entire field argument

[cconstantine at arxandefense dot com]

Given an assembly file like:

*** asm file ***
.global foo
lis 3, address@hidden
****************

When I assemble and run objdump I get:

*** as/objdump output ***
$ as -o test.o test.s && objdump -Dr test.o                                     
               

test.o:     file format elf32-powerpc
Disassembly of section .text:

00000000 <l1>:
   0:   3c 60 00 00     lis     r3,0
                        2: R_PPC_ADDR16_HI      foo+0x8
*************************

It appears that the relocation is being applied to the result of '<address of 
foo> + 0x8'.  My understanding 
is that the immediate field of the 'lis' should have a value of 0x8 and the 
relocation should only apply to 
'foo'.  The output I expect would look like:

*** expected as/objdump output ***
$ as -o test.o test.s && objdump -Dr test.o                                     
               

test.o:     file format elf32-powerpc
Disassembly of section .text:

00000000 <l1>:
   0:   3c 60 00 08     lis     r3,8
                        2: R_PPC_ADDR16_HI      foo
**********************************

I'm using ubuntu jaunty ppc.  My binutils package is version '2.19.1-0ubuntu3'. 
 Is this a problem with my 
understanding of how arguments in ppc assembly should be parsed, or in the way 
gas does assembly?
