23b0cf2340 * msdos system unit variable dos_psp renamed PrefixSeg for TP7 compatibility

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.

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).

04d8e8a5dc * On 64-bit targets, handle abs(int64) internally, using the same code as for abs(longint), i.e. without branching. Both generic and x86-specific pass 2 code is already suitable for different operand sizes, only type checking needs removal of excessive conversions to 32 bits.

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

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).

217ab9879c * Enabled internal handling of Abs(longint) for all targets. It has been implemented in cross-platform way ages ago (see tcginlinenode.second_abs_long), but not enabled on MIPS,SPARC and m68k. 
- RTL: removed MIPS,SPARC and m68k-specific implementations of Abs(longint), and marked the generic one as  required for bootstrapping purposes only.

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

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.

22e099d000 * sqrt(real): for targets with emulated floating point, invoke float64_sqrt or float32_sqrt from softfpu code. Testing on ARM CPU shows that float64_sqrt executes about twice faster and offers better accuracy than fpc_sqrt_real from genmath.inc. 
* softfpu.pp: changed float64_sqrt into a function, so it is consistent with other compiler-invoked routines.

fc5f45f65c * sqr(real) and sqrt(real): remove typeconv node inserted by initial call processing (see explanation in comments), allowing these functions to be evaluated using precision of argument. In particular, sqrt(single) and sqrt(double) now emit 'sqrtss' and 'sqrtsd' instructions on x86 targets with -Cfsse3. Non-x86 targets already have the necessary support in code generators. 
* abs(real): handle the same way as sqrt and sqr, i.e. without casting to bestreal and back.
