a72434e93a Trial to clarify heap for i8086 issues: 
- MSDOS heap in tinyheap.inc modified to use usual
  SysGetMem and similar names.
  - Use HAS_MEMORYMANAGER (used previously in wince source code,
  to specify that a memory manager is defined elsewhere than inside
  heap.inc include file.
  - Use
  - Remove TinyHeapMemoryManager Structure variable completely

  heaptrc.pp: remove unneeded macro code after name changes of tinyheap.inc

  msdos/system.pp now only defines HAS_MEMORYMANAGER macro
  win16/system.pp defines HAS_MEMORYMANAGER and FPC_NO_DEFAULT_HEAP
  as it still uses a different memory manager.
  __stkbottom variable added for win16 system.pp as it is required
  by i8086 specific stack check code.

759a4f8258 * don't try to build lnfodwrf on i8086-msdos, because it causes internal error 
200309041 and thus breaks building i8086-msdos snapshots entirely. Added test
  that reproduces the bug in a small program, so it can be fixed eventually.

4454332d7a * fixed the sysutils.GetEnvironment* functions for i8086-msdos 
- removed the envp variable from the msdos system unit, because it's not
  compatible with ppchar in all memory models (we use ppfarchar to avoid copying
  the environment in the program's data segment in near data memory models)

3ee0fc22d9 * use 'dw' instead of 'dd' to reference the heap from the i8086-msdos startup

45ed066fed * fixed SysUtils.FindFirst/FindNext/FindClose on i8086-msdos in the compact and 
large memory models by changing TSearchRec.FindHandle to a pointer (because
  THandle is 16-bit on this platform and is thus not able to hold a far pointer
  without truncating it)

7958466ef9 * on i8086-msdos, in the compact and large memory models, set the end of heap to

nickysn
9979aa702f + added the TP7-compatible pointer variables HeapOrg and HeapEnd, indicating,

  going to be used for catching attempts to free memory that is outside the
  heap.

1910177cf0 + added heapmax support to the $M directive on i8086-msdos. It is currently 
only implemented in the near data memory models. The far data models support
  is still a TODO.

nickysn
3164a10d9d * fixed a bug in the startup code for tiny memory model, which caused the 
program MCB address not to be calculated correctly, when the program is a tiny
  model .exe file, leading to possible memory corruption. Previously, the code
  assumed that dos_psp=CS, but that's only true for tiny .com files; tiny .exe
  files have a 256-byte gap between dos_psp and CS.

nickysn
7cfd7a66cd + create a special 'heap' segment with reserved space equal to heapsize (i.e. 
the value set by -Ch or the second parameter to the $M directive). This is
  equivalent to the heapmin value in Turbo Pascal 7 and ensures that the program
  has at least this amount of heap space available (otherwise DOS will show a
  'not enough memory' error and will refuse to load the program).

8ad63788c7 - do not emit a stack segment in the tiny memory model

  model

git-svn-id: trunk@27956 -
 2014-06-14 15:56:44 +00:00
nickysn
73d7f2aa18 * let the compiler generate the stack segment in i8086 near data memory models 
as well. Even though, in these models, the stack is dynamically allocated
  (because it goes on top of the heap, but the heap is variable size), there are
  still benefits:
  1) the program will run on a larger stack during initialization, before the
     actual stack (and heap) are ready
  2) in cases, when the system is extremely low on memory, DOS will reject to
     load the program if there's not enough memory for the stack the program
     requires. This way the startup code can be further simplified by omitting
     the 'not enough memory' check in the future (when we add the minimum heap
     size to the executable reserved space as well).

d4565aeec2 * in i8086 far data memory models add reference to the beginning of stack from 
the startup code, so the object module, containing the stack segment doesn't
  get smartlinked away

git-svn-id: trunk@27824 -
 2014-05-29 14:57:48 +00:00
nickysn
3cc8ff11e3 + generate the stack segment for i8086 far data memory models from within fpc 
itself (instead of having a fixed 16k stack in the startup code). This allows
  setting the stack size in these models with the -Cs option.

df6a2dce00 + unicodestring support for assign/erase/rename 
+ codepage support for textrec/filerec and the above routines
  * textrec/filerec now store the filename by default using widechar. It is
    possible to switch back to ansichars using the FPC_ANSI_TEXTFILEREC define.
    In that case, from now on the filename will always be stored in
    DefaultFileSystemEncoding
  * fixed potential buffer overflows and non-null-terminated file names in
    textrec/filerec
  + dodirseparators(pwidechar), changed the dodirseparators(pchar/pwidechar)
    parameters into var-parameters and gave those routines an extra parameter
    that indicates whether the p(wide)char can be changed in place if
    necessary or whether a copy must be made first (avoids us having to make
    all strings always unique everywhere, because they might be changed on
    some platforms via a pchar)
  * do_open/do_erase/do_rename got extra boolean parameters indicating whether
    the passed pchars point to data that can be freely changed (to pass on to
    dodirseparators() if applicable)
  * objects.pp: force assign(pchar) to be called, because
    assign(array[0..255]) cannot choose between pchar and rawbytestring
    versions (and removing the pchar version means that assign(pchar) will
    be mapped to assign(shortstring) in {$h-})
  * fixed up some routines in other units that depend on the format of
    the textrec/filerec.name field

    to indicate whether the platform-dependent part of the unit provides
    an ansistring/unicodestring interface to get environment variables
  + Windows version of getenvironmentvariable(unicodestring)
  + generic ansistring/unicodestring versions of GetEnvironmentVariable()
    in case the platform doesn't provide them

eeb98a0c0f - removed platform-specific implementations of GetCurrentDir, SetCurrentDir, 
CreateDir and RemoveDir, and implemented a generic one (based on the OS/2
    version) in the shared sysutils code (so that the filesystem code page
    support for the system unit routines can be reused)
  * include both ansistring and unicodestring versions of the above routines,
    and of ForceDirectories. Exception: GetCurrentDir, which cannot be
    overloaded based on function result and whose return type currently
    dependends on the FPC_UNICODE_RTL define

Jonas Maebe
d66d15aad3 + added mkdir/chdir/rmdir(rawbytestring) and (unicodestring) to the system unit 
* renamed platform-specific pchar versions of those rouines to do_*() and
    changed them to either rawbytestring or unicodestring depending on the
    FPCRTL_FILESYSTEM_SINGLE_BYTE_API/FPCRTL_FILESYSTEM_TWO_BYTE_API setting
  * implemented generic shortstring versions of those routines on top of either
    rawbytestring or unicodestring depending on the API-kind (in case of the
    embedded target, if ansistring are not supported they will map directly
    to shortstring routines instead)
  * all platform-specific *dir() routines with rawbytestring parameters now
    receive their parameters in DefaultFileSystemCodePage
  - removed no longer required ansistring variants from the objpas unit
  - removed no longer required FPC_SYS_MKDIR etc aliases
  * factored out empty string and inoutres<>0 checks from platform-specific
    *dir() routines to generic ones
  o platform-specific notes:
   o amiga/morphos: check new pathconv(rawbytestring) function
   o macos TODO: convert PathArgToFSSpec (and the routines it calls) to
     rawbytestring

62ee16278b * changed getdir(ansistring):ansistring to 
getdir(rawbytestring):rawbytestring so it can accept strings in any
    encoding and cleanly return results in DefaultRTLFileSystemCodePage
  + getdir(unicodestring):unicodestring
  * renamed the getdir implementation of all platforms except for embedded-
    without-ansistring-support to do_getdir(), and depending on the
    FPCRTL_FILESYSTEM_SINGLE_BYTE_API/FPCRTL_FILESYSTEM_TWO_BYTE_API define
    changed its shortstring parameter to ansistring or unicodestring. The
    do_getdir(rawbytestring) routine should just set the code page of the
    return value to DefaultFileSystemCodePage without conversion (not
    DefaultRTLFileSystemCodePage with conversion, that conversion is performed
    in getdir if necessary; this avoids double conversions in case
    getdir(unicodestring) is called)
  + generic getdir(shortstring) for platforms supporting either ansistrings or widestrings
  o platform maintainers:
   o OS/2: adjust code to supports paths > 255 characters if those are supported
   o Wii: adjust used callback to use rawbytestring to support paths > 255 characters and
     avoid shortstring->rawbytestring conversion overhead
   o Windows: GetCurrentDirectoryW is now always used (to prevent data loss)
