   3 main changes between versions 1.1 and 1.2:
   4
   5 * ports to linux and alpha, which should make snacc both endianess and
   6   64 bit clean.
   7 * to complement the destructors, T::T (const T&) and
   8   T &T::operator = (const T &) have been added to override the defaults
   9   supplied by the compiler. reason: simple pointer duplication may lead
  10   to unreferenced objects and to objects referenced more than once (on
  11   which the destructors delete may choke).
  12 * the files asn_useful.[hcC] and tbl.[ch] get regenerated automagically.
  13   since the compiler itself is compiled with it, a bootstapping version
  14   is included in the distribution.
  15 * the choice selector and all pointer members get initialized to get
  16   predictable behaviour from the destructors (C++ code only, the C code
  17   may still be broken!).
  18 * turned C++ inline functions into normal functions. this can reduce
  19   the size of .o files and executables dramatically! (the change was
  20   partially made by IBM ENC.)
  21 * the c++ lib compiles under gcc 2.6 (which has the bool type built-in).
  22 * GNU autoconf support added.
  23 * makefiles rewritten to provide the usual phony targets.
  24 * code duplication (4 config files, 3 c_libs) reduced.
  25 * C++ destructors added (partially contributed by IBM ENC).

  29                   Snacc Changes from version 1.0 to 1.1
  30
  31 Thanks to many bug reports from users of snacc 1.0, snacc 1.1 is more
  32 reliable.  Most of the changes between 1.0 and 1.1 are listed in the
  33 "1.0-to-1.1-changes" file.
  34
  35 Type tables are the biggest addition.  The rest were mostly bug fixes.
  36 If you reported a bug and you don't see the fix, I either didn't have
  37 time or simply forgot.  Sorry.
  38
  39 See README.future for the status of snacc now that I have graduated.
  40
  41 The remainder of this file contains descriptions of many of the fixes
  42 between version 1.0 and 1.1.  I am sure there are fixes that are not
  43 documented here.
  44
  45 =======================================================================
  46
  47 The GNU Library Public License (LGPL) has been punted.
  48
  49 =======================================================================
  50 Added table generation the compiler
  51
  52 files: src/{ tbl.c tbl.h gen_tbls.c }
  53 =======================================================================
  54
  55 Added table libraries and tools
  56
  57 files: tbl_include/* tbl_lib/* tbl_tools/* tbl_example/*
  58 =======================================================================
  59
  60 Re-aligned data structure for parse tree with code generated by
  61 newer version of snacc (yes, the parse tree was originally defined
  62 in ASN.1 - see asn1specs/asn1module.asn1)
  63
  64 =======================================================================
  65 defined T61String and ISO646String Tag codes.
  66
  67 files: snacc/c_inlcude/asn_tag.h and snacc/c++_inlcude/asn_tag.h
  68
  69 #define TT61STRING_TAG_CODE TELETEXSTRING_TAG_CODE
  70 #define ISO646STRING_TAG_CODE VISIBLESTRING_TAG_CODE
  71
  72 =======================================================================
  73
  74 Named arcs in OBJECT IDENTIFER values no longer generate ASN.1 integers.
  75 e.g.  test OBJECT IDENTIFIER ::={2 3 4 ds(5) 1}
  76
  77 used to be equivalent to:
  78     ds INTEGER ::= 5
  79     test OBJECT IDENTIFER ::= {2 3 4 ds 1}
  80
  81 Snacc now ignores the name (ds in this case).  Ideally the arc could
  82 be entered into an object identifier tree maintained by snacc.
  83
  84 files: snacc/src/val_parser.c
  85
  86 =======================================================================
  87
  88 Fixed bug in macro definition parsing that threw off the line
  89 number global.
  90
  91 file: asn1.lex
  92
  93 =======================================================================
  94
  95 Added file and line number information to import errors.
  96
  97 A lineNo field was added to the ImportElmt and ImportModule data
  98 structures.  The yacc code for the import elements & modules sets the
  99 lineNo values correctly.  The error reporting code in line_types.c and
 100 line_values.c now prints the line number info.
 101
 102 files: link_types.c link_values.c asn1module.h asn1.yacc
 103
 104
 105 =======================================================================
 106
 107 Added some line number info to multiply defined symbol error reports
 108
 109 file: err_chk.c - uses importElmt line number info
 110
 111 =======================================================================
 112
 113 Added line number info to export errors.
 114
 115 =======================================================================
 116
 117 Added file and line number info to typing errors for OBJECT
 118 IDENTIFIER values.  Also stopped errors that cascade from other
 119 OID values referencing a malformed oid value.
 120
 121 file: normalize.c
 122
 123
 124 =======================================================================
 125
 126 Error messages will be printed for recursively defined OBJECT
 127 IDENTIIFER values.
 128
 129 file: link_values.c
 130
 131 =======================================================================
 132
 133 Fixed bug #20. ie Not grabbing EOC on tagged (by def or in parent)
 134    CHOICEs embedded in other SET, SEQ, CHOICE, SET OF or SEQ OF types.
 135
 136 file: gen_c_dec.c
 137
 138 =======================================================================
 139
 140 Fixed bug #21. ie Value linking problem when assigning a value
 141 to a choice with a named number from one of the choice's elmts.
 142
 143 file: link_values.c, snacc_util.c (added routine "GetAllNamedElmts")
 144
 145 =======================================================================
 146
 147
 148 Fixed bug #22 - potentially not allocating enough space for
 149  a C++ field name conflict
 150
 151 file: snacc/src/back_ends/c++_gen/cpp_types.c
 152
 153 =======================================================================
 154
 155 Fixed nibble alloc bug.  curr pointer could be incremened past
 156    end ptr which then caused problems with new allocs.
 157
 158 file: c_lib/nibble_alloc.c tbl_lib/nibble_alloc.c
