34ffb184a8 * MASM and NASM assembler writers, added check for InlineLevel>0 so it suppresses entire source file processing, not just output of source lines. Without this, auto-generated instructions cause output of bogus line information. GAS writer already has similar check.

56bf42de57 compiler: implement record methods and class methods:
- rename tprocdef._class to tprocdef.struct and change the type from tobjectdef to tabstractrecorddef because methods can belong not to classes only now but to records too
  - replace in many places use of current_objectdef to current_structdef with typcast where is needed
  - add an argument to comp_expr, expr, factor, sub_expr to notify that we are searching type only symbol to solve the problem with records,objects,classes which contains fields with the same name as previosly declared type (like:
  HWND = type Handle;
  rec = record 
    hWnd: HWND;
  end;)
  - disable check in factor_read_id which was made for object that only static fields can be accessed as TObjectType.FieldName outside the object because it makes SizeOf(TObjectType.FieldName) imposible and since the same method was extended to handle records it also breaks a52 package compilation
  - rename tcallcandidates.collect_overloads_in_class to tcallcandidates.collect_overloads_in_struct and addapt the code to handle overloads in records too
  - fix searchsym_type to search also in object ancestors if we found an object symtable
  - add pd_record, pd_notrecord flags to mark procedure modifies which can or can't be used with records. Disallow the next modifiers for records: abstract, dynamic, export, external, far, far16, final, forward, internconst, internproc, interrupt, message, near, override, public, reintroduce, virtual, weakexternal,
Allow the next modifiers for records: static

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

b938ea0f2a * For cdecl functions the funcret is not popped by the caller when it is passed
as a para. But in case of the safecall convention, the funcret is always
   returned as para and from the c point-of-view this is a normal para. So it has
   to be popped normally. This was done by correcting the pop_size in 
   ti386callnode.pop_parasize but it's better to do this directly in 
   tcgcallnode.pass_generate_code.

181804e4b9 * Fixed passing parameters on the stack to cdecl interface-methods. The 'call'
shifted all the parameters on the stack. Now the 'self' parameter is
   declared as var, not const, restoring its original value is not necessary
   anymore

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)

* disallow pushfd/popfd for x86_64 (mantis #14862)
  * fixed assembling popfq with the internal assembler (it needs a rex.w
    prefisx, while pushfq doesn't)
  * changed the default opcode size of pushf/popf/pusha/popa in
    {$asmmode intel} from "native size" to 16 bit (compatible with Intel
    manuals and Kylix; in AT&T mode, the default size for those operations
    remains the native one)
  * changed pushf/popf in rtl/i386/* into pushfd/popfd because of the
    previous change

574d7eb70d * use call/pop instead of call/mov/ret to get the GOT pointer on

15e9c54b44 * fixed ABI compliance for parameter passing and function returning on all
x86-64 platforms (except for win64, which uses another ABI and which
    already complied to it) + test
  * fixed returning records containing 1 single or double field on darwin/i386,
    these have to be returned via ST0 instead of as a regular record
  * added support for LOC_FPUREGISTER and LOC_MMREGISTER in several places
    where they can now occur due to the previous two changes
  * made a few internalerrors unique

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

can remove regallocs for the allocated register and reinstert them
    before already processed instructions, thereby preventing the
    peephole optimizer from ever seeing the allocation for this register
    (mantis #13612)

6165536b5e + added {$modeswitch objectivec1}/-Mobjectivec1 mode switch to enable
the use of Objective-C 1.0 constructs. Because it is a mode switch, it
    can be used cumulatively with every syntax mode. Note that a {$mode xxx}
    statement resets all mode switches as well, so you cannot use the
    -Mobjectivec1 variant if you have such a statement in a unit. This
    modeswitch is currently only enabled for Darwin/PowerPC and Darwin/i386,
    as the backend support is not yet implemented for other platforms.
  + implemented selector() statement that can be used to create an Objective-C
    selector for the message with the specified *constant* name (in the future,
    it will also work for Objective-C method identifiers)
  + added SEL type to the system unit (the selector() statement returns it)
  + added all Objective-C segments to the assembler writers
  + (currently mostly dummy) objc1 unit that is automatically included if the
    {$modeswitch objectivec1} statement is used
  + some tests for the selector() statement
