 Hi,
 
 This bug seems to be related to:
 
   Thu Apr  3 18:57:19 CEST 2003  Jan Hubicka  <jh@suse.cz>
 
         * i386.c (print_operand): Do not bypass output_addr_const at flag_pic.
 
 Since the testcase is so small, I'll repeat it here:
 
 --8<--
 static struct { int i; int j; } s;
 
 int fnV (int, ...);
 void fnA (void)
 {
   fnV(s.j, fnV(s.j));
 }
 --8<--
 
   $ gcc -fPIC -O2 -c foo.c
   /tmp/cc4zCzUj.s: Assembler messages:
   /tmp/cc4zCzUj.s:12: Error: suffix or operands invalid for `lea'

>Description:
Compiling the following simple program:

  static struct { int i; int j; } s;
  int fnV (int, ...);
  void fnA (void)
  {
    fnV(s.j, fnV(s.j));
  }

with -fPIC -O1 or -fPIC -O2 gives:

  $  gcc -c -fPIC -O1 foo.c
  /tmp/ccxT9xXg.s: Assembler messages:
  /tmp/ccxT9xXg.s:13: Error: suffix or operands invalid for `lea'

The assemblers I tried were

  GNU assembler version 2.12.90.0.1 (i386-linux) using BFD version 2.12.90.0.1 20020307 Debian/GNU Linux
  GNU assembler version 2.13.90 (i686-pc-linux-gnu) using BFD version 2.13.90 20030407
>How-To-Repeat:
gcc -c -fPIC -O1 foo.c
gcc -c -fPIC -O2 foo.c
