Hello,
 
I am using GNU tools to build an application 
from  windows NT for a powerPC target.
 
The ld version that i use is : cygnus-2.6  

emulation used is elf32-powerpc
I can do simple program that run correctly on 
the target, but 
I got some trouble with the Locate with builtion 
functions AT and LOADADDR.
 
I found that LOADADDR function is only available 
since version 2.8. 
 
I have not already install version 2.8 (some 
trouble with NT), 
but my real problem is 
with the builtin function AT .
 
Doing that in ld script : 
 
Ex 
:                 
.mdata  DATA_START : AT (IMAGE_DATA_START) 
 
In the generated file ELF, the VMA and the LMA 
(see in dump file) are the same and equal to DATA_START.
AT instruction seems to have no 
effect.
 
 
I will be very pleased if someone could help 
me.
Thank you.
Vincent.
