f2c82e32cd - removed g_indirect_sym_load() from hlcgobj/hlcg2ll because this cgobj
method is only used anymore internally in cgobj.tcg and its descendants
  * made tcg.g_indirect_sym_load() protected to ensure it stays that way

9e51b0837c * avoid problems when using a_load*loc* calls with 3-byte-sized parameters
(fix internalerror when compiling webtbs/tw16163 on non-Darwin/ARM)

edd42aa42a * moved subsetref/reg and bit_set/test support from cgobj to hlcgobj for
future use by high level code generator targets
   o this in turn required that all a_load*_loc* methods are called via
     hlcg rather than via cg, since a location can be a subsetref/reg and
     and those are no longer handled in tcg
   o that then required moving several force_location_* routines into
     thlcg because they use a_load_loc*, but did not take tdef size
     parameters (which are required by the thlcg a_load_loc* routines)
   o the only practical consequence is that from now on, you have to
     use hlcg.location_force_mem/reg() (fpureg not yet) and
     hlcg.gen_load_loc_cgpara() instead of the removed versions from ncgutil,
     and hlcg.a_load*loc*() instead of cg.a_load*loc* if a subsetref/reg
     might be involved

641b259aed * adjusted thlcg.g_rangecheck() implementation so it can be used for all
targets and removed (the almost identical) tcg.g_rangecheck()

aee5380ae0 * merged trunk up to r20882
o support for the new codepage-aware ansistrings in the jvm branch
   o empty ansistrings are now always represented by a nil pointer rather than
     by an empty string, because an empty string also has a code page which
     can confuse code (although this will make ansistrings harder to use
     in Java code)
   o more string helpers code shared between the general and jvm rtl
   o support for indexbyte/word in the jvm rtl (warning: first parameter
     is an open array rather than an untyped parameter there, so
     indexchar(pcharvar^,10,0) will be equivalent to
     indexchar[pcharvar^],10,0) there, which is different from what is
     intended; changing it to an untyped parameter wouldn't help though)
   o default() support is not yet complete
   o calling fpcres is currently broken due to limitations in
     sysutils.executeprocess() regarding handling unix quoting and
     the compiler using the same command lines for scripts and directly
     calling external programs
   o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
     to the make command line

10efb5b6e2 * handle records returned in floating point registers in the high->low level
code generator translation (as done by some ABIs, such as most x86-64
    platforms and darwin/i386)
   -> all regressions in jvmbackend branch for darwin/i386 fixed

ce88df680b + symansistr conditional define that, when activated, makes the symbol/
mangled name handling ansistring rather than pshortstring based (required
    for JVM target; little effect on speed, some extra memory usage)

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)

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

09207563d5 + hlcg implementation of gen_load_para_value(); no support yet for copying
value parameters when necessary, nor for -gt variable trashing

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

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)
