This must be a new bug, the testcase passed previously, the register name
(esi) is rejected at link-time only.
#1 0x0000000000d4dbba in make_decl_rtl (decl=0x7ffff5a2c140)
at /space/rguenther/src/svn/trunk/gcc/varasm.c:1207
1207 error ("invalid register name for %q+D", decl);
(gdb) l
1202 reg_number = decode_reg_name (asmspec);
1203 /* First detect errors in declaring global registers. */
1204 if (reg_number == -1)
1205 error ("register name not specified for %q+D", decl);
1206 else if (reg_number < 0)
1207 error ("invalid register name for %q+D", decl);
(gdb) p asmspec
$2 = 0x7ffff5b58401 "esi.2318"
we mangle the register name now. That's of course bogus. It seems we
put the global register vars into the alias machinery now? Honza?
