3d3a42b911 * improvement to r16050 for non-fixed stack targets: they never have to use
a temporary parameter location, since calls cannot overwrite parameters
    already on the stack in that case (it will just grow)

4780278e7b Fix Mantis #11783:
* Dispinterfaces can be assigned/typecasted to Variants and vice-versa.
  * At the same time, disabled corbainterface assignment compatibility with Variants. Simply intermixing COM and CORBA interfaces is wrong since it causes reference counting calls on CORBA interfaces.
* Dispinterfaces are returned in parameter, similar to regular interfaces.
* Fixed crash in comobj.pp due to incorrect typecast.
* Fixed incorrect dispinterface declarations in the test itself. Now it compiles and works (if MS Excel is installed).

8b0301409a + i386/iphonesim target for the new iPhoneSimulator in Xcode 3.2.4 and
later: the same as i386/darwin, except
      a) uses the non-fragile Objective-C ABI/runtime
      b) does not require stubs for direct calls/jumps (not required for
         i386/darwin under 10.6 and later either, but still generated
         there for backwards compatibility)
      c) only the same packages are enabled as for ARM/Darwin
      d) MacOSAll is compiled specifically for the iPhoneSimulator SDK
    This target also defines the symbol "darwin" apart from the target
    name "iphonesim" for source code compatibility reasons.

f13f6627c4 * moved use_fixed_stack from cgutils to a method in paramgr so it can
be used outside the code generator
  * renamed tabstractprocdef.requiredargarea into callerargareasize,
    and also added calleeargareasize field; added init_paraloc_info(side)
    method to init the parameter locations and init those size fields and
    replaced all "if not procdef.has_paraloc_info then ..." blocks with
    procdef.init_paraloc_info(callersize)"
  * moved detection of stack tainting parameters from psub to
    symdef/tabstractprocdef
  + added tcallparanode.contains_stack_tainting_call(), which detects
    whether a parameter contains a call that makes use of stack paramters
  * record for each parameter whether or not any following parameter
    contains a call with stack parameters; if not, in case the current
    parameter itself is a stack parameter immediately place it in its
    final location also for use_fixed_stack platforms rather than
    first putting it in a temporary location (part of mantis #17442)
  * on use_fixed_stack platforms, always first evaluate parameters
    containing a stack tainting call, since those force any preceding
    stack parameters of the current call to be stored in a temp location
    and copied to the final location afterwards

57bd6d2685 + merged nestedprocvars branch
+ support for nested procedural variables:
    o activate using {$modeswitch nestedprocvars} (compatible with all
      regular syntax modes, enabled by default for MacPas mode)
    o activating this mode switch changes the way the frame pointer is
      passed to nested routines into the same way that Delphi uses (always
      passed via the stack, and if necessary removed from the stack by
      the caller) -- Todo: possibly also allow using this parameter
      passing convention without enabling nested procvars, maybe even
      by default in Delphi mode, see mantis #9432
    o both global and nested routines can be passed to/assigned to a
      nested procvar (and called via them). Note that converting global
      *procvars* to nested procvars is intentionally not supported, so
      that this functionality can also be implemented via compile-time
      generated trampolines if necessary (e.g. for LLVM or CIL backends
      as long as they don't support the aforementioned parameter passing
      convention)
    o a nested procvar can both be declared using a Mac/ISO Pascal style
      "inline" type declaration as a parameter type, or as a stand-alone
      type (in the latter case, add "is nested" at the end in analogy to
      "of object" for method pointers -- note that using variables of
      such a type is dangerous, because if you call them once the enclosing
      stack frame no longer exists on the stack, the results are
      undefined; this is however allowed for Metaware Pascal compatibility)

27f6376fd4 * when determining whether a temporary paraloc can be in a LOC_REGISTER,
look at paraloc^.size rather than cgpara.size, because e.g. a 32 bit
    record (-> cgpara.size=OS_32) may have to be passed via a
    LOC_MMREGISTER (-> paraloc^.size=OS_F32 or OS_M32)

283018a3bf * changed tprocdef.funcretloc[] from a tlocation into a tcgpara so it can
represent complex locations (required for full x86-64 ABI support,
    which is not yet implemented) -> lots of special result handling
    code has been removed and replaced by the parameter handling
    routines
  + added support for composite parameters (and hence function
    results) to tcg.a_load_ref_cgpara() (so it can be used for
    handling, e.g., 64 bit parameters on 32 bit platforms)
  * the above fixed writing past the end of allocated memory when
    handling records returned in registers on x86-64 whose size is
    not a multiple of 8 bytes (mantis #16357)
  - removed the x86-64 and PPC specific versions of a_load_ref_cgpara(),
    as they are now handled correctly by the generic version
  * moved the responsibility of allocating tcgpara cpu registers
    (using paramanager.allocparaloc()) from the callers of
    cg.a_load*_cgpara() to the cg.a_load*_cgpara() methods
    themselves (so the register allocation can be done efficiently
    when dealing with function results)
  * for the above, renamed paramanager.alloc/freeparaloc() to
    paramanager.alloc/freecgpara(), and use paramanager.allocparaloc()
    to allocate individual pcgparalocations instead
  * fixed the register size of SSE2 function result registers for
    x86-64 (when used for floating point), which results in removing
    a few superfluous "movs? %xmm0,%xmm0" instructions
  * fixed compilation of paramanagers of avr, m68k and mips after r13695
    and also updated them for these new changes

cc5aeb09de * fixed handling the result value of functions where the result type is
forced to something else by the compiler (internal rtl functions etc),
    necessary for the objc branch
  * fixed adding all used function result registers to the list of
    registers that may need to be saved before a function call

718694d1d6 * always specify an explicit alignment for tgobj.gettemp (so e.g.
shortstring temps don't get maximum alignment)
  * changed some gettemptyed() calls into gettemp() calls (gettemptyped
    means that this temp can only be used for temps of that type,
    which is necessary for refcounted types but not for floats)

f36e5411af * split cpu64bit compiler define into
a) cpu64bitaddr, which means that we are generating a compiler which
       will generate code for targets with a 64 bit address space/abi
    b) cpu64bitalu, which means that we are generating a compiler which
       will generate code for a cpu with support for 64 bit integer
       operations (possibly running in a 32 bit address space, depending
       on the cpu64bitaddr define)
   All cpus which had cpu64bit set now have both the above defines set,
   and none of the 32 bit cpus have cpu64bitalu set (and none will
   compile with it currently)
  + pint and puint types, similar to aint/aword (not pword because that
    that conflicts with pword=^word)
  * several changes from aint/aword to pint/pword
  * some changes of tcgsize2size[OS_INT] to sizeof(pint)
