Re: gcc extension to control variable names works with sgiCC, but not sgicc.

[David Goodwin <goodwin@xxxxxxxxxxxxx>]

Yes, that seems to work. Here's the patch:

==== gccfe/tree_symtab.cxx ====
***************
*** 554,561 ****
    if (TREE_CODE(decl_node) == ERROR_MARK)
      exit (RC_USER_ERROR);
  
!   if (DECL_NAME (decl_node))
!     name = IDENTIFIER_POINTER (DECL_NAME (decl_node));
    else {
      DevWarn ("no name for DECL_NODE");
      name = "__unknown__";
--- 554,561 ----
    if (TREE_CODE(decl_node) == ERROR_MARK)
      exit (RC_USER_ERROR);
  
!   if (DECL_ASSEMBLER_NAME (decl_node))
!     name = IDENTIFIER_POINTER (DECL_ASSEMBLER_NAME (decl_node));
    else {
      DevWarn ("no name for DECL_NODE");
      name = "__unknown__";
