c89ea4412f * disallow using inline nodes with a non-void resultdef as statements 
(e.g. length, lo/hi, ord, etc). Not the same as mantis #9918, but
    somewhat related

git-svn-id: trunk@8770 -

c408d9bb1d * fixed regression of webtbs/tw2789 caused by r8270 (setting vs_read 
without vsf_must_be_valid means that it's not really read, but
    only used by sizeof or so)

9adb202a92 * Rework the constexprint to allow operations from low(int64) to high(qword). 
+ Some initial work on a formaldef which also carries the typinfo of a parameter.

69cf42c4f7 * fixed val(s,int64) (it accepted values in the range 
high(int64+1)..high(qword) if written in decimal notation) + test
  * fixed range checking of qword constants parsed by the compiler
    (they always gave a range error if > high(int64), because the compiler
     internally stores them as int64)
  * turn off range checking flag of rdconstnodes created by the parser
    from _INTCONST, because those are already range checked by the
    way they are parsed using val()

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

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()
     multiple times for the same register doesn't matter. We need again
     a way to specify that a register is currently a regvar and as such
     should not be freed when you call ungetregister() on it.
