5c8d0d87cd o better code generation for avr: 
* omit entry/exit code, if no frame pointer is used, partly fixes issue #27842
  * take advantage of adiw/sbiw
  * make more often use of ldd/std

03fa8336de o several avr fixes 
* handle function result of FPC_MUL_WORD correctly
  * use mov ...,r1 to load a register with zero instead of clr ..., this might enable the register allocator to 
    coalesce these moves in the feature
  * use tst/dec instead of cpi/sub in the shifting loops, this reduces register pressure on r16 and higher

e4fea2ebc8 * Dummy implementations of a_bit_scan_reg_reg and g_stackpointer_alloc in tcg, removes the need to override these methods in every descendant code generator solely to avoid "constructing a class with abstract method" warning.

10522e9779 Disabled a_adjust_sp optimized steps for now.

2227045e23 Replace forbidden chars in more places in the GAS assembler writer. 
Add support for .set and .weak on AVR.
Fix 64 bit negation on AVR.
Add cpu_capabilities to cpuinfo.pas and fixed some peephole optimizations.
Pass >4 byte parameters by reference.

e33550b67d Added support for X,Y,and Z register aliases plus low/high forms, and post-incrementation in AVR assembler reader. 
Cleaned up parameter and funcretloc information generation in AVR paramanger, and made it closer to GCC's calling convention.
Fixed a number of codegenerator bugs generating invalid or broken instructions: CP operands were swapped, a number of instructions had immediate operands, and stack frame epilogue wasn't complete.
Added a bunch of peephole optimizations that clears the generated code up a lot.

9c1f917e3a * a_call_ref functionality cannot be implemented efficiently at code generator level, because references need specific preparations at earlier points. Moved this support to tcgcallnode and its x86 descendants, and got rid of all ifdef's around. 
+ x86 targets now directly call procedure variables located in references.
- a_call_ref method removed from tcg and thlcgobj.

69c29a415f * pass the procdef to getintparaloc instead of only the proccalloption, so 
that the type of the parameters can be determined automatically
   o added compilerproc declarations for all helpers called in the compiler
     via their assembler name, so we can look up the corresponding procdef

7a0ae38700 + also specify the parameter def when allocating a parameter via 
getintparaloc + adapted all call sites of getintparaloc. This
    led to a number of additional, related changes:
   o corrected the type information for some getintparaloc parameters
   o don't allocate some intparalocs in cases they aren't used
   o changed "const tvardata" parameter into "constref tvardata" for
     fpc_variant_copy_overwrite to make pass-by-reference semantics
     explicit
   o moved a number of routines that now have to call find_system_type()
     from cgobj to hlcgobj so that cgobj doesn't have to start depending
     on the symtable unit
   o added versions of the cpureg alloc/dealloc methods to hlcgobj that
     call through to their cgobj counter parts, so we can call save/restore
     the cpu registers before/after calling system helpers from hlcgobj
     (not implemented in hlcgobj itself, because all basic register
      allocator functionality is still part of cgobj/cgcpu)
