efc5e339d0 * use an enum instead of integer constants to represent inline numbers
* compinnr.inc include file converted to a unit
* inline number field size stored in ppu increased from byte to longint
* inlines in the parse tree (when written with the -vp option) now printed with
  their enum name, instead of number

66e82f1655 + i386: generate optimized code for 64-bit arithmetic shifts by constant amount. Shifts by 63 and by less than 32 take just two instructions, shifts by 32..62 bits are done with 3 instructions.

59abf2555b * types.pas renamed to defbase.pas because D6 contains a types
unit so this would conflicts if D6 programms are compiled

4a176c81bc * removed n386ld and n386util units

4dcd96747e * moved entry and exitcode to ncgutil and cgobj
* 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

3bcfe33002 * fixed stackcheck that would be called recursively when a stack
error was found
  * generic changeregsize(reg,size) for i386 register resizing
  * removed some more routines from cga unit
  * fixed returnvalue handling
  * fixed default stacksize of linux and go32v2, 8kb was a bit small :-)

peter
5b242f7741 * tlocation,treference update
* LOC_CONSTANT added for better constant handling
  * secondadd splitted in multiple routines
  * location_force_reg added for loading a location to a register
    of a specified size
  * secondassignment parses now first the right and then the left node
    (this is compatible with Kylix). This saves a lot of push/pop especially
    with string operations
  * adapted some routines to use the new cg methods

7fb55bf4e4 + a_loadfpu_* and a_loadmm_* methods in tcg
* register allocation is now handled by a class and is mostly processor
    independent (+rgobj.pas and i386/rgcpu.pas)
  * temp allocation is now handled by a class (+tgobj.pas, -i386\tgcpu.pas)
  * some small improvements and fixes to the optimizer
  * some register allocation fixes
  * some fpuvaroffset fixes in the unary minus node
  * push/popusedregisters is now called rg.save/restoreusedregisters and
    (for i386) uses temps instead of push/pop's when using -Op3 (that code is
    also better optimizable)
  * fixed and optimized register saving/restoring for new/dispose nodes
  * LOC_FPU locations now also require their "register" field to be set to
    R_ST, not R_ST0 (the latter is used for LOC_CFPUREGISTER locations only)
  - list field removed of the tnode class because it's not used currently
    and can cause hard-to-find bugs
