694ccf3df3 + dummy support for untyped var/const/out parameters on the JVM target
o includes basic "auto-boxing" infrastructure to support Delphi.NET-
     compatible untyped parameters as described at
     http://hallvards.blogspot.com/2007/10/dn4dp24-net-vs-win32-untyped-parameters.html

e775e2d9ae * moved gen_entry_code/gen_exit_code from ncgutil to hlcgobj,
and overrode both with empty stubs for the JVM

f57e9778d4 * migrated gen_initialize_code and gen_finalize_code from ncgutil to
hlcgobj so it can be overridden with target-specific code (e.g.,
    the JVM target has to add initialisation code to allocate regular
    arrays and records in constructors and unit/program initialisation)

88df6573a0 * moved de2regtyp() from defutil to hlcgobj, so it can be overridden
(and override for the JVM, making the register type for records
     R_ADDRESSREGISTER instead of R_INTREGISTER there)

5abf6d0aa4 + thlcgobj support of the managed open array initialization fixes of
svn r17068,17071,17081,17136
  * changed all init_paras code in both thlcgobj and ncgutil to use
    location_get_data_ref() instead of direct a_load_loc_reg()/
    ref.base:=reg so it also works with the JVM target
  * changed all init_paras code so it works with targets that do
    not pass an implicit high parameter for open array (and a similar
    fix in ncgcal)
  + added support for initializing array (both regular and open)
    "out" parameters of reference counted types on the JVM target
    (the arrays will be initialised with nil rather than an empty
     array for implementation reasons, see comments in compproc.inc)
  * factored out calling of functions in the system unit directly
    from hlcgobj

2c313e397e + support for regular arrays and open arrays
o support for copying value parameters at the callee side if they were
     passed by reference in hlcg
   o JVM g_concatcopy() implementation for arrays
   o moved code to get length of an array from njvminl to hlcgcpu so it can
     be reused elsewhere as well
   o export array copy helpers from system unit for use when assigning one
     array to another
   o some generic support for types that are normally not implicit pointers,
     but which are for the JVM target (such as normal arrays)
  * handle assigning nil to a dynamic array by generating a setlength(x,0)
    node instead of by hardcoding a call to fpc_dynarray_clear, so
    target-specific code can handle it if required
  * hook up gethltemp() for JVM ttgjvm so array temps are properly
    allocated

a2a6b2fd1d + "reference" temps that sort of implement pointer-style functionality for
platforms that don't support pointers (by make a copy of all registers
    part of a reference)

0e87627218 + gethltemp() to allocate a temp specifying full type information even
for regular temps. This is required for targets that need special
    handling of the temps depending on the type
  * converted most gettemp() calls to gethltemp() calls

28740dce2d - removed extra "fordefinition" parameter again from tprocdef.mangledname(),
since the definition-specific adorning of JVM mangled names is Jasmin-
    specific, and such code has no place in symdef
  * moved code to adorn JVM mangled names for Jasmin definitions to agjasmin

9a9ea1f257 + limited thlcg.gen_load_cgpara_loc() implementation (only loc_reference
support), passed through to original ncgutils version in thlcg2ll
  + thlcgobj.location_force_mem() implementation
  * order parameters for jvm similar to those for i386 without fixed_stack,
    so we don't need temporary paralocations
  * converted most of ncgcal to thlcg
  * disabled special handling for virtual methods for jvm in ncgcal, as all
    invocations are name-based there
  + njvmcal with special jvm callnode support:
   o always move the function result into a memory temp
   o when freeing an unused function result, use a_pop(2) and adjust
     the internal evaluation stack height counter
   o after the call instruction, adjust the evaluation stack height counter
     by subtracting the number of the pushed parameter slots, adjusted for
     the slots taken up by the function result

71deda6f50 + added interface to ncgutil.gen_load_loc_cgpara() to hlcgobj + generic
implementation (without loc_©mmregister support)
  * moved ncgutil.gen_load_return_value() to hlcgobj, and factored out
    architecture-specific behaviour to load an uninitialised function result
    into a virtual method (+ JVM-specific implementation of that method),
    gen_load_uninitialized_function_result()
  + added hlcgx86 unit and thlcgx86 type to override the
    thlcgobj.gen_load_uninitialized_function_result() method for x87
    function results; the i386 and x86_64 units now instantiate thlcgx86
    instead of thlcg2ll
  * moved calling of ncgutil.gen_load_loc_cgpara() from ncgcal also to hlcgobj
  -> returning function results works for JVM

8439e1472e * moved def2regtyp() from jvm/hlcgcpu to defutil, and extended it to
handle vectorfpu (floatdef->MMREG) and softfloat (floatdef->INTREG)
  + thlcg.getregisterfordef(), which uses def2regtyp() to allocate a register
    appropriate to hold values of that tdef type
  + generic thlcg.location_force_reg() implementation. Note that for
    low-level code generator targets it may be slightly less efficient than
    the implementation in hlcg2ll (from ncgutil) because it does not play
    any tricks with the register or location size, or with reference offsets,
    to truncate values

e4d322bcdb + default implementation for for the *_checkoverflow() methods in case
setflags is false

    = true in case cs_check_overflow is disabled

742f4ee12e + first (partial) implementation of thlcg for the jvm
+ added arrayreftype field to treference for the jvm, because
    array loads have to be performed using special instructions,
    so this information has to be passed on to the code generator.
    This information will have to be added in t(cg)vecnode.
  * moved concatenating the generated code for a procedure to the
    al_procedures list to thlcg.record_generated_code_for_procdef(),
    which is overridden by jvm/hlcgcpu to attach that code to the
    procdef it belongs with. The reason is that a Java class file
    can only contain code for one class, so we have to write out
    the assembler grouped per class instead of in the order the
    routines appear in the source code
  * also committed forgotten changes in psub after moving the
    register allocator initialisation to hlcgobj

09ac60b084 + a_call_name_inherited(), by default calls a_call_name() (for the JVM
target you have to use a different opcode for calling inherited methods
    than for regular methods)

0ee702b3a2 * tprocdef.mangledname now gets an extra boolean parameter indicating
whether the mangled name is for defining a symbol, or for referencing
    it later (e.g. for a call or load of its address). The reason is that
    on the JVM both cases are different.
  + jvmdef unit to encode types according to the JVM rules
  + tprocdef.jvmmangledname() to encode a procdef's JVM mangled name
    (the common part of defining/referencing it; tprocdef.mangledname
     afterwards adorns it as required)

db203431b2 + hlcgobj: high level code generator class. It has basically the same
interface as cgobj, except that all type parameters are defs instead
    of tcgsize. Also includes some procedures from ncgutil (over time,
    all of ncgutil will probably integrated here so it can be easily
    overridden)
  + hlcg2ll: pass-through implementation of thlcg that forwards everything
    either to cgobj or ncgutil, for use by the classic code generator
    clients (all current platforms)
  + added "def" field to tcgpara to record the tdef of the parameter
    (used by the high level code generator)
