5acc8b44a8 * activated internal get_frame for x86 
* turn off stackframe optimizations on x86 if get_frame is called
    in the current routine, or if the address of a nested function
    is taken in the current routine
  + test for the above
  * this fixes the IDE when compiled with stackframe optimizations
    on x86

ce58e15393 * fix coff section names to fix resourcestrings with 
the external linker
  * create import libraries for dll imports, this uses

    object files directly without needing an assembler pass
  * store import_dll and import_name in ppu
  * external linker uses import libraries
  * internal linker uses import info from symtables,
    no dlls are needed anymore

3056a64bf0 * fixed regvars support. Needs -doldregvars to activate. Only tested with 
ppc, other processors should however only require maxregvars and
    maxfpuregvars constants in cpubase.pas. Remember to take scratch-
    registers into account when defining that value.

745efb2c47 * issameref() to test if two references are the same (then emit no opcodes) 
+ ret_in_reg to replace ret_in_acc
    (fix some register allocation bugs at the same time)
  + save_std_register now has an extra parameter which is the
    usedinproc registers

peter
ac71268ce6 * saving of asmsymbols in ppu supported 
* asmsymbollist global is removed and moved into a new class
    tasmlibrarydata that will hold the info of a .a file which
    corresponds with a single module. Added librarydata to tmodule
    to keep the library info stored for the module. In the future the
    objectfiles will also be stored to the tasmlibrarydata class
  * all getlabel/newasmsymbol and friends are moved to the new class

59abf2555b * 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

399036f1c2 * State tracker work 
* The whilen and repeatn are now completely unified into whilerepeatn. This
  allows the state tracker to change while nodes automatically into
  repeat nodes.
* Resulttypepass improvements to the notn. 'not not a' is optimized away and
  'not(a>b)' is optimized into 'a<=b'.
* Resulttypepass improvements to the whilerepeatn. 'while not a' is optimized
  by removing the notn and later switchting the true and falselabels. The
  same is done with 'repeat until not a'.

eeae0e4c00 + Added the beginning of a state tracker. This will track the values of 
variables through procedures and optimize things away.

21b3a10f02 + defines.inc -> fpcdefs.inc to avoid conflicts if compiling by hand

peter
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

87aa88e9b7 + generic FPC_CHECKPOINTER 
+ first parameter offset in stack now portable
* rename some constants
+ move some cpu stuff to other units
- remove unused constents
* fix stacksize for some targets
* fix generic size problems which depend now on EXTEND_SIZE constant

peter
70ff711f73 * mangledname rewrite, tprocdef.mangledname is now created dynamicly 
in most cases and not written to the ppu
  * add mangeledname_prefix() routine to generate the prefix of
    manglednames depending on the current procedure, object and module
  * removed static procprefix since the mangledname is now build only
    on demand from tprocdef.mangledname

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

it too) ("merged")

6a15178f0f * fixed web bug #1593 
* writing of procvar headers is more complete (mention var/const/out for
    paras, add "of object" if applicable)
  + error if declaring explicit self para as var/const
  * fixed mangled name of procedures which contain an explicit self para
  * parsing para's should be slightly faster because mangled name of
    procedure is only updated once instead of after parsing each para
    (all merged from fixes)
