fpc/compiler

This directory contains the sources of the Free Pascal Compiler

To recompile the compiler, use the batch file
mppc386.bat

If you want to build a m68k version to cross compile from i386 to m68k
use the batch file
mppc68k.bat

If you want to modify the compiler, please read first the compiler
writer's guide (cws.txt) in that directory.


Changes in the syntax or semantic of FPC:
-----------------------------------------
28/01/99 implicit conversion from boolean to integer is not possible
anymore (solved several bugs) but this could lead to errors
on previously accepted code (PM)
01/02/99 c styled comments are supported (/* ... */), mainly
for the Sibyl sources of Medigo (FK)
02/02/99 class destructors take now two parameters: flag
if the helper routine should free the instance and
self pointer (FK)
22/02/99 PROTECTED and PRIVATE have now the same behavior
as in TP
09/03/99 small records and arrays passed by value to a function are now directly copied
into a 4 bytes parameter (needed for C and DLL calls) (PM)
11/03/99 the makefile.fpc is now also needed for the compiler and RTL, you can
find it in the base.zip package (PFV)
24/03/99 new directives UNITPATH,INCLUDEPATH,OBJECTPATH,LIBRARYPATH to
set the searchpaths where to find the files for that module (PFV)
25/03/99 new directive STATIC +/- or on/off , works like -St commandline
switch
02/04/99 rtl/cfg/ directory has been removed, it's not used anymore
15/04/99 FINALIZATION is supported
21/04/99 Default assembler for i386 changed to AT&T instead of direct
25/04/99: initialized vars supported in Delphi mode (only $J+ mode)
getting the address of an untyped const is now
forbidden as in BP
27/04/99 New unit format PPU016, you need to recompile all older units
01/05/99 Internal assembler. Assembler readers now support MMX,KNI
instructions.
12/05/99 rtl/utils/ directory moved to utils/. Moved the utils only needed
for compiler development to compiler/utils/
13/05/99 Classes are now only allowed in the ObjFpc or Delphi mode. Use
{$mode objfpc} or {$mode delphi}. Or from commandline -S2 or -Sd
16/05/99 Remove options -Up (use now -Fu) and -Fg (use now -Fl)
17/05/99 Redesign of ansistring temporary handling, please report
any problems
17/05/99 Most stuff of the objpas unit is now in the system unit
because the new temporary ansistring handling support
exceptions and exceptions need the class OOP model
18/05/99 The compiler will stop directly if there are errors in the
commandline parameters
