8ca4c80785 * mark tasmsymbols as declared in the taillvmdecl constructor so that we
don't have to do this everywhere such a declaration is generated

eef6f05697 * specify the asm section type when creating an LLVM declaration
o in case it's a read-only section, mark the data as "constant"

394dfdd220 * ensure that all initialised items have a type (and only one):
o remove the accompanying tdef operands from tai operands, because such
     tai operands should have a tdef already
   o check that every queued tai is a tai_simpletypedconst (which have a
     type)
   o wrap queued bitcast/getelementptr tai instances with a
     tai_simpletypedconst

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

7ebb1b813f + basic support infrastructure in the llvm assembler writer to write out
typed constant data
   o llvm declarations now get an extra "initdata" list that contains the
     typed constant data associated with this declaration (if any)

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

dad45d63b1 * improved symbol alias handling (pass in old sym instead of name, add
pointer add end of aliased procdef)

227ff0ea48 * llvm requires that single precision constants are exactly representable
using single precision -> convert them to single precision in the code
    generator

e70175a10e * added extra boolean parameter to getelementptr taillvm constructors to
indicate whether or not an implicit indirection should be added (always
    was done until now)

98be5b0825 * correctly handle loads/stores of aggregate types if the source and
destination types are different: the pointer types of the load/store must
    be converted in that case, rather than the loaded/to be stored value
    (you can't bitcast aggregates in LLVM)

b7803ab974 + llvm support for the register allocator. While llvm works with virtual
registers itself, it requires them to be in SSA form. Therefore we
    spill all registers that are written more than once to memory.
  + support in the generic register allocator for generating code that is
    SSA-safe
  + spilling helpers for llvm

3296984bd9 + classes for llvm instructions (ait_llvmins), procedure definitions
(ait_llvmprocdef), global variable definitions (ait_llvmvarsym)
    and alias definitions (ait_llvmalias)
