5fde39cd69 * reinstated trashing of out parameters with -gt (see mantis 8216, 
fix for the compiler was in symtable.pas)

879a1594e1 * don't trash out parameters, because the caller may expect them to be 
unchanged in case the callee doesn't touch them (e.g. srdef in pexpr.pas)
  * extra safety to not trash any typed constants and initialised variables

b951947b64 * partially fixed Delphi compatibility for assembler procedures: in case 
only parameters on the stack are passed and if the function result is
    not referenced, don't allocate a stackframe. Fixes mantis 8155, but
    see that bug report for other rules (there's one error there: Delphi
    *does* allocate a function result for non-string/variant/interface
    if @result is referenced)

e815b923d5 * a_loadfpu_* gets two size parameters: fromsize and tosize 
* fixed downsizing the precision of floating point values
  * floating point constants are now treated using only the minimal
    precision required (e.g. 2.0 is now a single, 1.1 extended etc)
    (Delphi compatible)

319d92fe9a * Release register of by value parameter after making its local copy. It fixes bug when local stack location is referenced using big (>4k) PC relative offset by ARM CPU. In this case temp register is needed and wrong temp register is allocated.

6997121c18 * also perform "SSA" for certain loads (currently derefn, righthand side of 
assignmentn and callparan), reduces number of long lived conflicts.
    Mainly helpful on register-starved cpus such as i386.

Jonas Maebe
eccbc78e04 + support for bitpacked arrays: 
+ use {$bitpacking on/+} to change the meaning of "packed"
      into "bitpacked" for arrays. This is the default for MacPas.
      You can also define individual arrays as "bitpacked", but
      this is not encouraged since this keyword is not known by
      other compilers and therefore makes your code unportable.
    + pack(unpackedarray,index,packedarray) to pack
      length(packedarray) elements starting at
      unpackedarray[index] into packedarray.
    + unpack(packedarray,unpackedarray,index) to unpack
      packedarray into unpackedarray, with the first
      element being stored at unpackedarray[index]
  * todo:
    * "open packed arrays" and rtti for packed arrays are not
      yet supported
    * gdb does not properly support bitpacked arrays

    to a multiple of 8)

Jonas Maebe
5f699c7838 + -gt, -gtt, -gttt and -gtttt switches to trash local variables with 
different values (resp. $55, $AA, $EF and $00) in function/procedure
    prologs to help find uninitialized uses. Should still be extended
    for "out" parameters.
