svenbarth 9fd8c8718a Partial merge of r28846 (without the global assembler symbols)
To correctly generate the import library for a package we need to resolve the dangling external symbols of all units. For this each unit now stores which symbols it exported from another unit and it also stores all global and external assembler symbols it has (maybe this can be streamlined later on, but for now this works).

entfile.pas:
  + new entry for the imported unit symbols
fmodule.pas, tmodule:
  + new field unitimportsyms which holds all symbols imported by a unit from another unit
  + new method to add an imported symbol
  * create, destroy & reset: correctly instantiate/free the two new lists
fppu.pas, tppumodule:
  + new field unitimportsymsderefs to hold the derefs during loading from/storing to PPU
  + new method buildderefunitimportsyms to generate the derefs for each imported symbol
  + new method derefunitimportsyms to resolve each imported symbol deref
  + new method readunitimportsyms to read the imported symbols from the PPU
  + new method writeunitimportsyms to write all imported symbols to the PPU
  * load_implementation: read the imported symbols if their entry is encountered
  * writeppu: generate the derefs for the imported symbols and write them to the PPU
  * load_usedunits: resolve the imported symbols once all derefs are known
symtable.pas:
  * addsymref: if the symbol is not from the current unit than mark it as imported
ppu.pas:
  * increase PPU version

ptype.pas Implement support for parsing "generic [class] procedure" and "generic [class] function" in non-Delphi modes. Since "generic" is a prefix it is quite ugly to implement, but from a Pascal language point of view it fits better than "procedure generic xyz". 2015-11-20 16:50:58 +00:00
raatt.pas * Handle possible relocation types in assembler reader using a single AS_RELTYPE token, rather than with individual tokens for each case. Since possible relocations are target-dependent, this will allow to support any amount of them without modifying the base tattreader class. 2016-02-23 21:28:46 +00:00

rgbase.pas
rgobj.pas * Make trgobj.uses_registers method return True when registers of appropriate type are specified in list of used registers (after assembler blocks), but not used otherwise. This is a missing piece of r30011, enabling code generator to actually save/restore such registers. Resolves #28421. 2015-12-07 19:12:20 +00:00
scandir.pas Add new Delphi compatible switch {$G+/-}, {$IMPORTEDDATA ON/OFF} which handles generation of indirect references for cross unit variable accesses if needed for the target. 2016-03-18 22:04:57 +00:00
scanner.pas * Replaced hacks with resetting 'c' to zero and decreasing inputpointer by boolean parameter to skipcomment and skipoldtpcomment. This parameter specifies whether first character of comment should be read. 2016-01-03 17:07:15 +00:00

This directory contains the sources of the Free Pascal Compiler

If you want to compile/modify the compiler, please read first the
programmers manual.

To recompile the compiler, you can use the batch files :
 + mppc386.bat    if you want to build a cross compiler from i386 to m68k
 + mppcsparc      if you want to build a cross compiler from i386 to SPARC
 
 or
Use the make utility as following
  
      make OS_TARGET="compiler OS target" \
      CPU_TARGET="compiler CPU target" \
      FPCCPUOPT="Optimization level" \
      PP="compiler used to compile FPC" \
      COMPILER_OPTIONS="Options passed to compiler" \
      
      
If an option is omitted, then target CPU/OS will be same as current CPU/OS
 
Possibles targets are : linux go32v2 win32 os2 freebsd beos netbsd amiga haiku
atari sunos qnx netware openbsd wdosx palmos macos macosx emx
   
Possible compiler switches (* marks a currently required switch):
  -----------------------------------------------------------------
  GDB*                support of the GNU Debugger
  I386                generate a compiler for the Intel i386+
  x86_64              generate a compiler for the AMD x86-64 architecture
  M68K                generate a compiler for the M68000
  SPARC               generate a compiler for SPARC
  POWERPC             generate a compiler for the PowerPC
  VIS                 generate a compile for the VIS
  DEBUG               version with debug code is generated
  EXTDEBUG            some extra debug code is executed
  SUPPORT_MMX         only i386: releases the compiler switch
                      MMX which allows the compiler to generate
                      MMX instructions
  EXTERN_MSG          Don't compile the msgfiles in the compiler, always
                      use external messagefiles, default for TP
  NOAG386INT          no Intel Assembler output
  NOAG386NSM          no NASM output
  NOAG386BIN          leaves out the binary writer, default for TP
  NORA386DIR          No direct i386 assembler reader
  TEST_GENERIC        Test Generic version of code generator
                      (uses generic RTL calls)
  -----------------------------------------------------------------
  cpuflags            The target processor has status flags (on by default)
  cpufpemu            The target compiler will also support emitting software
                       floating point operations
  cpu64bitaddr        The targets use a 64-bit address space (pointers and
                       the default integer type are 64 bit)
  cpu64bitalu         The target cpu has 64-bit registers available (unless
                       cpu64bitaddr is also defined, pointers and default
                       integer type remain 32 bit, but the cpu can perform
                       64 bit calculations directly without needing helpers)
  -----------------------------------------------------------------

  Required switches for a i386 compiler be compiled by Free Pascal Compiler:
  GDB;I386

to build a compiler to SPARC target using a Win32/i386 you just use :
      make CPU_TARGET=SPARC
