fb27dff638 * generate ".abiversion 2" directive when targeting ppc64/ELFv2 
* generate code to load the TOC register if it's required, and
    emit the the ".localentry" directive to indicate to the linker
    where the actual function body starts
  * support the ".localentry" directive in the ppc64 assembler reader
   o disable the fpc_qword_to_double() assembler implementation for
     ELFv2, because we can't manually insert the .localentry directive
     before the stack allocation code
  * perform indirect calls on ppc64 via R12 in ncgcal, as R12 needs to
    contain the function address on entry on ppc64/ELFv2 (and it's
    a volatile register, so there's no problem with always using
    it)

27a7c0863b + added constructors tai_const.Create_int_codeptr and .Create_int_dataptr. To be

9f39188253 * moved the tai_*typedconst classes to aasmcnst to make use of def-related 
helpers in a cleaner way (defutils would not belong in the uses clause of

1e7d9c9f0e + support for instruction operands that are tai themselves in the llvm 
backend (required for inserting bitcasts/ptrtoint/... operations inside
    typed constant declarations)
   o taillvm constructors for creating bitcast-style and getlementptr
     operations that accept a tai as their source/base operand

b0ff41406a * grouped all tai_real* types into a single tai_realconst type, 
to free up space for more ait_* types in taitype (can't have
    more than 32 because they have to fit in a small set)
   o factored out writing of floating point numbers as an array of
     byte in the external assemblers

6dcfd73d21 + support for a_call_name() on the llvm target: 
o make use of the fact that callparanodes always first load everything
     in temporary parameters (allocated via paramanager.createtempparaloc)
     -> we pass those temporary paralocs to the llvm call nodes and ignore
     the "real" locations with physical registers
   o all function results are forced to memory before handing them back
     to the generic code generator to avoid having to deal with special
     result locations and llvm<->pascal type differences (llvm removes
     the extra temp stores/loads while optimising)
   o ideally, the llvm code generator should share the common code with
      the generic code generator for a_load_ref_cgpara() at some point in
      the future

b82053ef40 * reworked handling of defined/declared symbols in llvm: we now automatically 
generate declarations when external symbols are referred in a taillvm
    instruction
  * added "declared" field to tasmsymbol for llvm to make avoid declaring a
    symbol multiple times (harmless, but unnecessary)
  * all kinds of declarations/definitions are now handled using the new
    taillvmdecl, the old separate types have been removed

46f8e78d1f + Support GOT/gp-relative constants in GAS and internal assemblers, MIPS and i386.

fe4cac96be + added overloads to tai_const.Createname and Create_type_name, which take a Tasmsymtype parameter; to be used for declaring external symbols which reside in the data segment with AT_DATA, which is necessary for i8086 medium and compact memory models (where code and data pointers are of different size)
