    * locals and paras are allocated in the code generation
 | 
						|
    * tvarsym.localloc contains the location of para/local when
 | 
						|
      generating code for the current procedure
 | 
						|
 | 
						|
  Revision 1.17  2003/08/21 15:10:51  peter
 | 
						|

    * changed tt_persistant to tt_persistent :)
 | 
						|
    * tempcreatenode now doesn't accept a boolean anymore for persistent
 | 
						|
      temps, but a ttemptype, so you can also create ansistring temps etc
 | 
						|
 | 
						|
  Revision 1.14  2003/05/16 14:33:31  peter
 | 
						|
    * regvar fixes

 | 
						|
  Revision 1.12  2002/04/25 20:15:40  florian
 | 
						|
    * block nodes within expressions shouldn't release the used registers,
 | 
						|
      fixed using a flag till the new rg is ready
 | 
						|
 | 
						|
  Revision 1.11  2002/11/26 22:59:09  peter

    * merged isconvertable and is_equal into compare_defs(_ext)
 | 
						|
    * made operator search faster by walking the list only once
 | 
						|
 | 
						|
  Revision 1.9  2002/10/29 10:01:22  pierre

    * types.pas renamed to defbase.pas because D6 contains a types
 | 
						|
      unit so this would conflicts if D6 programms are compiled
 | 
						|
    + Willamette/SSE2 instructions to assembler added
 | 
						|

						|
    * foreach gets extra argument for passing local data to the
 | 
						|
      iterator function
 | 
						|
    * -CR checks also class typecasts at runtime by changing them
 | 
						|
      into as
 | 
						|
    * fixed compiler to cycle with the -CR option
 | 
						|
    * fixed stabs with elf writer, finally the global variables can
 | 
						|
      be watched
 | 
						|
    * removed a lot of routines from cga unit and replaced them by
 | 
						|
      calls to cgobj
 | 
						|
    * u32bit-s32bit updates for and,or,xor nodes. When one element is
 | 
						|
      u32bit then the other is typecasted also to u32bit without giving
 | 
						|
      a rangecheck warning/error.
 | 
						|
    * fixed pascal calling method with reversing also the high tree in
 | 
						|
      the parast, detected by tcalcst3 test
