If I use this patch in addition to the s390 backend fix,
Ada bootstrap goes through on 64-bit:
Index: gcc/ada/bindgen.adb
===================================================================
RCS file: /cvs/gcc/gcc/gcc/ada/bindgen.adb,v

*************** package body Bindgen is
*** 485,491 ****
begin
if U.Set_Elab_Entity then
! Set_String (" extern char ");
Get_Name_String (U.Uname);
Set_Unit_Name;
Set_String ("_E;");
--- 485,491 ----
begin
if U.Set_Elab_Entity then
! Set_String (" extern char __attribute__((__aligned__(1))) ");
Get_Name_String (U.Uname);
Set_Unit_Name;
Set_String ("_E;");
I'm not sure whether this is the preferred fix; in particular
I don't understand why those variables need to have forced
alignment in the first place ...
Bye,
Ulrich
