[Bug translator/2437] New: function parameter access addressing error in IA64

["bibo dot mao at intel dot com" <sourceware-bugzilla at sourceware dot org>]

It is has reported in http://sourceware.org/bugzilla/show_bug.cgi?id=1295, it 
is in IA32 and X86_64 architecture, and now it has been solved. But this 
problem still exists in IA64 platform.
 I run "readelf  --debug-dump vmlinux" command, there is some information about 
sys_open function.
<1><402067>: Abbrev Number: 81 (DW_TAG_subprogram)
     DW_AT_sibling     : <40213b>
     DW_AT_external    : 1
     DW_AT_name        : (indirect string, offset: 0x276fb): sys_open
     DW_AT_decl_file   : 1
     DW_AT_decl_line   : 966
     DW_AT_prototyped  : 1
     DW_AT_type        : <3f5c63>
     DW_AT_low_pc      : 0xa00000010011d840
     DW_AT_high_pc     : 0xa00000010011d9e0
     DW_AT_frame_base  : 1 byte block: 5c       (DW_OP_reg12)
 <2><40208b>: Abbrev Number: 100 (DW_TAG_formal_parameter)
     DW_AT_name        : (indirect string, offset: 0x3ae3b): filename
     DW_AT_decl_file   : 1
     DW_AT_decl_line   : 965
     DW_AT_type        : <3f7249>
     DW_AT_location    : 2 byte block: 90 28    (DW_OP_regx: 40)

It shows that filename parameter is put in register r40, but in fact this 
parameter should be passed by r32 register.
