svenbarth ccecf2c13c Fix comparisons (aka usage of flag/CCR register) 
m68k/aasmcpu.pas, taicpu.spilling_get_operation_type:
  * add all Sxx instructions as "operand_write" instructions

m68k/n68kadd.pas, t68kaddnode.getresflags:
  * use the correct operation in case of swapped nodes

m68k/cgcpu.pas, tcg68k.g_flags2reg:
  - don't move a 0 to the register, because this will CLR it and thus the flags won't be valid anymore...
  - NEG would have been the wrong operation (NOT would have been correct), but it isn't needed anyway...
  * simplify the method by handling the address register case only when necessary

link.pas + chmod 755 on executable files produced by internal linker. I missed this "small" detail for half a year because all development was going on a NTFS drive where everything is executable. 2013-01-13 17:18:11 +00:00

ngenutil.pas * Fixed incorrect condition (a linked list always has at least one dummy element) which was causing every unit to have a threadvar table, regardless of actual presence of threadvars.

ogbase.pas - TObjData.sectiontype2options: removed oso_keep flags. They don't have any effect here because this function is used only during assembling, and oso_keep cannot be represented in object files and therefore gets lost before linking. 2013-01-11 17:14:44 +00:00

ogmap.pas
ognlm.pas * Don't calculate data position of each object section. Instead, write out a copy of exesection's memory image, i.e. every objsection is placed at the same offset from its owning exesection both on disk and in memory. This approach is simpler and works regardless of alignment requirements, while existing one could work only if SectionDataAlign<=SectionMemAlign. 2013-01-02 10:10:23 +00:00

optcse.pas * setelement nodes itself should not be considered, since setelement 2012-11-20 21:15:38 +00:00

pass_2.pas * merged trunk up to r20882 2012-04-15 15:54:10 +00:00
pbase.pas - get rid of m_all, use a set instead for tokens, this allows to disable/enable tokens depending on the language mode 2012-09-30 21:03:35 +00:00
pdecl.pas Add support for generic type constraints. They are currently only useful to stop specialization of a generic. The parsing of a generic is still too lax and needs to be changed in the future... 2012-12-16 13:44:58 +00:00
pdecobj.pas compiler: handle calling convention of record (class)constructors/destructors later as it is done with other record methods 2013-01-06 17:04:28 +00:00

pdecvar.pas Fix one problem type of Mantis #23546. A record must not contain a static array that uses itself as an element type (in can contain a dynamic array however) otherwise an infinite loop is encountered when checking whether the record needs special init/final code. 2013-01-09 14:07:01 +00:00
pexports.pas * handle exports with a name consisting of a single character correctly 2012-07-22 14:23:09 +00:00
pexpr.pas Move the handling of "misstyled" floating point constants like "2." or "2.e10" from the scanner to the parser. This way type helpers calls for integer constants can be parsed correctly in the future. 2013-01-10 16:23:00 +00:00
pgenutil.pas Fix for revision 23344. 2013-01-09 09:12:39 +00:00

rgbase.pas Use TRegNameTable instead of array[tregisterindex] of string[10] 2012-10-22 10:23:21 +00:00
rgobj.pas Also check for the type of the register when replacing it. In certain circumstances this can still lead to access to invalid memory resulting either in an access violation or invalid registers. 2012-10-19 19:35:45 +00:00
scandir.pas + support setpeoptflags directive, resolves #23447 2012-12-10 19:17:25 +00:00
scanner.pas Move the handling of "misstyled" floating point constants like "2." or "2.e10" from the scanner to the parser. This way type helpers calls for integer constants can be parsed correctly in the future. 2013-01-10 16:23:00 +00:00

symtype.pas Add support for generic type constraints. They are currently only useful to stop specialization of a generic. The parsing of a generic is still too lax and needs to be changed in the future... 2012-12-16 13:44:58 +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
