be39a88daa * slice() doesn't support packed arrays 
git-svn-id: trunk@4454 -

eccbc78e04 + support for bitpacked arrays: 
+ use {$bitpacking on/+} to change the meaning of "packed"
      into "bitpacked" for arrays. This is the default for MacPas.
      You can also define individual arrays as "bitpacked", but
      this is not encouraged since this keyword is not known by
      other compilers and therefore makes your code unportable.
    + pack(unpackedarray,index,packedarray) to pack
      length(packedarray) elements starting at
      unpackedarray[index] into packedarray.
    + unpack(packedarray,unpackedarray,index) to unpack
      packedarray into unpackedarray, with the first
      element being stored at unpackedarray[index]
  * todo:
    * "open packed arrays" and rtti for packed arrays are not
      yet supported
    * gdb does not properly support bitpacked arrays

58381ff7b6 * made chararray handling 98% TP-compatible, fixes web bugs 3012 
and 4080. The compatibility differences are:
      a) writing a chararray which is zero-based but not zero-
         terminated does not cause a buffer overflow
      b) non-zero-based chararrays can also be read

    The difference was that previously, all chararrays were treated
    as pchars. In TP/Delphi (and now also in FPC), this is only done
    for zero-based chararrays. For non-zero-based ones, the entire
    contents of the array should always be used (including #0's).

    The default parameters in the system unit for the chararray
    helpers are to avoid having to use a define for bootstrapping.

42ec76598c * new categories for vs_*: vs_declared, vs_initialised, vs_read, 
vs_written, vs_readwritten. vs_initialised is the old vs_assigned;
    vs_used has been replaced by vs_read, vs_written and vs_readwritten
  * the valid_for_*() routines in htypechk now get an extra parameter to
    decide whether or not errors should be reported

694eee6cae + support to store ttempcreate/ref/deletenodes in registers 
* put temps for withnodes and some newnodes in registers
   Note: this currently only works because calling ungetregister()

     a way to specify that a register is currently a regvar and as such
     should not be freed when you call ungetregister() on it.
