gdb for powerpc on i586 linnux host
>Description:
we have an embedded system in which an application is dynamically added to the system, the symbols are added to gdb using the add_symbol_file command with the text, data, bss section information, if the object has global static variables, their address is incorrectly computed by gdb
in the proper context

c file looks like

static int test;

test_fn()
{
test = 5;
}

the object is dynamically relocated and the symbols added to gdb using add_symbol_file test.o -Ttext......

at break of the test_fn
p/x &test incorrect address of test ie the address is actual address +/- 4, this happens for only global static variables, in this object, everything else is fine
