-Right now there is no documentation for the GCC tree -> rtl interfaces
-(or more generally the interfaces for adding new languages).
-
-Such documentation would be of great benefit to the project.  Until such
-time as we can formally start documenting the interface this file will
-serve as a repository for information on these interface and any incompatable
-changes we've made.
-
-Aug 31, 1998:
-  The interface to HANDLE_PRAGMA has changed.  It now takes three arguments.
-  The first two are pointers to functions that should be used to read characters
-  from the input stream, and to push them back into the input stream respectively.
-  The third argument is a pointer to a null terminate string which is the first
-  word after #pragma.  The expression supplied by HANDLE_PRAGMA should return
-  non-zero if it parsed and implemented the pragma.  Otherwise it should return
-  zero, and leave the input stream as it was before the expression was evaluated.
-
-  A new back-end definable macro has been added: INSERT_ATTRIBUTES.  This macro
-  allows backend to add attributes to decls as they are created.
-
-Jun 10, 1998:
-  The interface to lang_decode_option has changed. It now uses and argc/argv
-  interface to allow for options that use more than one input string. The new
-  declaration is: int lang_decode_option (int argc, char** argv). It now
-  returns the number of input strings processed, or 0 if the option is
-  unknown.
-
-Jun  7, 1998:
-  Front-ends must now define lang_init_options.  It is safe for this
-  function to do nothing.  See c-lang.c.
-
-Apr 21, 1998:
-  Front ends which link with c-common or other files from the C/C++
-  front-ends may need to handle TI types.  Look for references to
-  [unsigned]int_DI_type_node in your front end.  If you have references
-  to these variables, you'll need up update the front end.
-
-  To update the front end you must mirror all the code which currently
-  deals with intDI_type_node to also handle intTI_type_node.

-Apr 7, 1998:
-  The interface between toplev.c and the language front ends for opening the
-  source file has changed:
-
-  o init_lex() has been renamed to init_parse (char *filename) where filename
-    is the name of the source file.
-  o The code in toplev.c which opened the source file should be moved to
-    the new init_parse function.
-  o toplev.c now calls finish_parse() instead of closing the source file
-    using fclose(). This should now be done in finish_parse, if necessary.
-
-Apr 1, 1998:
-  Front-ends must now define lang_print_xnode.  It is safe for this
-  function to do nothing.  See c-lang.c.
-
-Feb 1, 1998:
-
-  GCC used to store structure sizes & offsets to elements as bitsize
-  quantities.  This causes problems because a structure can only be
-  (target memsize / 8) bytes long (this may effect arrays too).  This
-  is particularly problematical on machines with small address spaces.
-
-  So:
-
-    All trees that represent sizes in bits should have a TREE_TYPE of
-    bitsizetype (rather than sizetype).
-
-    Accordingly, when such values are computed / initialized, care has to
-    be takes to use / compute the proper type.
-
-    When a size in bits is converted into a size in bytes, which is expressed
-    in trees, care should be taken to change the tree's type again to sizetype.
-
-    We've updated C, C++, Fortran & Objective-C to work with the new
-    scheme.  Other languages will need to be updated accordingly.

-?? 1997:
-
-  In an effort to decrease cache thrashing and useless loads we've changed the
-  third argument to the DEFTREECODE macro to be a single char.  This will
-  effect languages that defined their own tree codes (usually in a .def file).
-
-  Old way:
-
-    DEFTREECODE (CLASS_METHOD_DECL, "class_method_decl", "d", 0)
-
-  New way:
-
-    DEFTREECODE (CLASS_METHOD_DECL, "class_method_decl", 'd', 0)
