50e5256f8e * system.pp: 
+ Add MSDOS specific version of SysInitFPU, using Get/SetInterrput Vectors
    to test coprocessor presence.
    * Do not call SetupEnvironment in startup code.
    + Add internal_envp variable (nil by default).
    + Change envp to function, which calls SetUpEnvironment,
    if internal_envp is nil.
    * Do not call SetupArguments at startup,
    instead call it from inside paramcount or paramstr
    + Add SaveInt10 and SavdeInt75

  * dos.pp: Also swap Interrupt vectors $10 and $75

  * sysutils.pp: Adapt to envp change in system unit.

ac3b9ac979 Avoid placing COMPILER_UNITTARGETDIR in the prerequisite list of assmebler files,

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.

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.

- 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

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

git-svn-id: trunk@28442 -
 2014-08-18 13:54:20 +00:00
nickysn
9979aa702f + added the TP7-compatible pointer variables HeapOrg and HeapEnd, indicating, 
respectively, the start and end of the tiny heap. Eventually they are also
  going to be used for catching attempts to free memory that is outside the

f7dd4f640a - rm the 'Memory allocation error' and 'Not enough memory' error messages from

e7e02467fc * fixed bug in MsDos and Intr in i8086 far data memory models not cleaning their

nickysn
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.

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).

nickysn
8ad63788c7 - do not emit a stack segment in the tiny memory model 
- rm the reference to the top of the stack segment from the startup code in tiny
  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).
