8326543918 m68k: apparently, the right place for the sar qword helper is still in the CPU include, not the 64bit helper include. this fixes linux m68k build.

7758ad9313 m68k: clear the FPU Control Register at program start. This fixes some testcode randomly failing on AmigaOS, where the FPCR state is inherited from the parent task. Also added the FPCR layout and rounding modes info, based on the Motorola 68k PRMm68k.inc

acd3ea8750 * m68k: Fixed parameter passing to conform to ABI: 
* records are passed by value
  * records with size of 1,2 or 4 are returned in registers
  * parameters with size<4 are justified on the stack according to big-endian target

Now everything except floating-point parameters is compatible with C code compiled with "-malign-int -mrtd".
Compatibility with "-mno-align-int" is achievable by changing target_info.maxCrecordalign to 2, but doings so causes a lot more troubles because RTL (incorrectly) assumes that records declared with {$PACKRECORDS C} are aligned to pointer size.

+ Reuse parameter locations. Since everything is passed on stack, it reduces code size quite a bit.
- tm68kparamanager.getintparaloc removed, generic implementation has been tested and works as expected.

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.

83f4344c20 Fix around 30 tests for m68k by fixing FillChar: 
* completely disable the DBRA part for CPUs without DBRA
  * replace CMP/BNE with BPL which uses the flags of the SUB instruction
Additional fixes for the other two (still disabled) DBRA alternatives:
  * use BPL instead of BMI (which is wrong)

This fixes cases like "Writeln('')" which is used inside InternalExit if an unhandled exception happened.

4d1e42e891 rtl/m68k/setjump.inc:

rtl/m68k/m68k.inc:

f204f84f6a rtl/m68k/m68k.inc, move:

8469741700 + Added additional addr pointer parameter to 
get_caller_frame, get_caller_addr and dump_stack
  with default NIL value to systemh.inc.
  + Added new get_addr function.
  system.inc: Use get_addr and get_frame to call
  HandleErrorAddrFrame instead of HandleErrorFrame
  in several error functions.
  Modify dump_stack to use frame and addr parameters.
  Provide a dummy get_addr function returning nil.
  i386/i386.inc, x86_64./x86_64.inc: Provide real
  implementation of get_addr function.
