4e2fb9d28b * MIPS: fixed O_MOVE_SOURCE and O_MOVE_DEST constants (they were swapped, amazing that it ever worked with such a mistake). 
+ Spilling for SEB and SEH
* Another attempt to get spilling of 3-operand form DIV/DIVU be done correctly.

9991ee4165 m68k: support loading of refs to data registers, also when explicit paraloc is set and it's a register, use that directly, this fixes several syscall-related corner cases on Amiga

030885727e * Do not use sym.realname but sym.name in the mangledname for the Dwarf-3 debuginfo. This makes it possible to mix Dwarf-2 and Dwarf-3 debug info into one executable.

244ac12794 Fix for Mantis #26615. 
htypechk.pas, tcallcandidates:
  * collect_overloads_in_struct: we need to check the deftyp of the extended def for record- or objectdef, not the deftyp of the helper which will always be objectdef anyway.

+ added test

5f2821ee5f * Moved handling of emulated floating point negation into new virtual method tcgunaryminusnode.second_float_emulated. Also changed it into simple flipping of the sign bit, which is how it is defined by IEEE 754, and already done for ARM targets. Relevant ARM-specific parts can now be removed, and m68k code gets significantly better without further efforts.

0f9e8f84bb * tcgcallnode.pass_generate_code: pass the correct vmt pointer type parameter to 
location_force_reg when generating code for a call to a virtual class method,
  called through a class reference var. This bug went unnoticed so far, because
  on all platforms, except i8086 medium and compact memory models, the size of
  a vmt pointer is the same as the size of a procvar. Even in the i8086 medium
  and compact memory models, the previous code would generate correct code,
  because thlcg2ll.a_load_loc_reg uses loc.size (which was correct) in the case
  when fromsize=tosize (both of which were wrong, but equal), due to the check
  in hlcg2ll.pas:555. Thanks to Jonas for finding this bug!
