e04df465ef * The label which is generated by traisenode is not a jump target. Mark 
this label as nf_internal, which means the label does not impact the
  code flow. This leads to a much better register allocation.

ac1e0f96bd * replaced tentryfile.get/putsmall/normalset() with a common tget/putset 
that expects an open array of byte, and use it for all sets
   o since all sets need to be typecasted to an array type of the appropriate
     size, we'll get a compilation error in case this needs to be done and
     that also tells us at the same time that the ppu version will need to
     be increased
  * enabled {$packset 1} for the compiler, as this is now safe with the above
    changes

243c967967 Commit of new debug feature implemented by J. Gareth Moreton 
Allows compilation of compiler using -dDEBUG_NODE_XML
  which will generate a NAME-node-dump.xml file for each 
  unit, program or library compiled,
  containing a XML description of the nodes handled during
  compilation of the unit, program or library.

e5c2d13671 * Do not set pi_needs_got in current_procinfo.flags at the node level, since the GOT usage can only be estimated there. Instead set the pi_needs_got flag at places where the GOT register is accessed during the code generation. This eliminates generation of the unneeded initialization of the GOT register and fixes linker errors when the _GLOBAL_OFFSET_TABLE_ symbol is referenced but no actual GOT references are present.

51e68eb302 * fixed several places where the interface crc could change: 
o unsetting po_inline while parsing the implementation for various reasons
     (interprocedural goto/label, accessing a local in a parent frame,
      having nested procedures)
   o instead handle this via the pio_inline_not_possible flag
   o noreturn can no longer be specified only in the implementation

91d5457b38 * moved around/replaced the following procedures to stop nflw from depending 
on pdecsub (node units should not depend on parser units):
   o maybe_add_public_default_java_constructor()
   o handle_calling_convention()
   o create_finalizer_procdef() (replaced with create_outline_procdef())
   o insert_record_hidden_paras()
   o handle_calling_convention()
   o proc_add_definition()
   o build_parentfpstruct()
   o maybe_guarantee_record_typesym()
   o get_first_proc_str()
  * factored out the creation of a procinfo for a nested procdef based on a
    subnodetree of the current procdef into tprocinfo.create_for_outlining()
