commit 9730e6ccc4307a03ae2a0dd5c8a17a30fcf9b1f2
Author: Yao Qi <yao@codesourcery.com>

    Compute the function length instead of hard coding it
    
    In Dwarf::assemble in dwz.exp, 10 is hard-coded in it,
    
     	    subprogram {
     		{name main}
     		{low_pc main addr}
    		{high_pc "main + 10" addr}
     	    }
    
    however, the length of main function varies on architectures.  The
    hard-coded 10 here causes dwz.exp fails on some targets, such as
    nios2.
    
    This patch is to add some code to compute the length of function main,
    which is similar to what we are doing in entry-values.exp.

    	* gdb.dwarf2/dwz.exp: Compile main.c to object.  Restart GDB
    	and compute the length of function main.  Save it in
    	$main_length.
    	(Dwarf::assemble): Use $main_length instead of hard-coded 10.
    	(top-level): Use gdb_compile to compile objects into
    	executable and restart GDB.  Remove invocation to
    	prepare_for_testing.
