d1538ab023 o added ARM VPFv2/VFPv3 support:
+ RTL support:
      o VFP exceptions are disabled by default on Darwin,
        because they cause kernel panics on iPhoneOS 2.2.1 at least
      o all denormals are truncated to 0 on Darwin, because disabling
        that also causes kernel panics on iPhoneOS 2.2.1 (probably
        because otherwise denormals can also cause exceptions)
    * set softfloat rounding mode correctly for non-wince/darwin/vfp
      targets
    + compiler support: only half the number of single precision
      registers is available due to limitations of the register
      allocator
    + added a number of comments about why the stackframe on ARM is
      set up the way it is by the compiler
    + added regtype and subregtype info to regsets, because they're
      also used for VFP registers (+ support in assembler reader)
    + various generic support routines for dealing with floating point
      values located in integer registers that have to be transferred to
      mm registers (needed for VFP)
    * renamed use_sse() to use_vectorfpu() and also use it for
      ARM/vfp support
    o only superficially tested for Linux (compiler compiled with -Cpvfpv6
      -Cfvfpv2 works on a Cortex-A8, no testsuite run performed -- at least
      the fpu exception handler still needs to be implemented), Darwin has
      been tested more thoroughly
  + added ARMv6 cpu type and made it default for Darwin/ARM
  + ARMv6+ implementations of atomic operations using ldrex/strex
  * don't use r9 on Darwin/ARM, as it's reserved under certain
    circumstances (don't know yet which ones)
  * changed C-test object files for ARM/Darwin to ARMv6 versions
  * check in assembler reader that regsets are not empty, because
    instructions with a regset operand have undefined behaviour in that
    case
  * fixed resultdef of tarmtypeconvnode.first_int_to_real in case of
    int64->single type conversion
  * fixed constant pool locations in case 64 bit constants are generated,
    and/or when vfp instructions with limited reach are present

  WARNING: when using VFP on an ARMv6 or later cpu, you *must* compile all
    code with -Cparmv6 (or higher), or you will get crashes. The reason is
    that storing/restoring multiple VFP registers must happen using
    different instructions on pre/post-ARMv6.

5a2ccfff52 --WARNING: start build process with FPC 2.2.4; won't work when
starting with a previous 2.3.1 or compiler built from the objc branch
  + added basic objcprotocol support (only for external protocols
    currently)
     o use in type declaration: "type xp = objcprotocol ... end;"
     o when defining a root class that implements it:
       "type yc = objcclass(xp) ... end" (note: no support yet
       for something like "objcclass(id,xp)" or so)
     o when defining a non-root class that implements a protocol:
       "type zc = objcclass(nsobject,xp) ... end"
     o includes support for "required" and "optional" sections
     o no support yet for the objcprotocol(<protocol>) expression
       that enables getting a class instance representing the
       protocol (e.g., for use with "conformsToProtocol:")
     o message names have to specified in protocol declarations,
       but if an objcclass implements a protocol, the message names do
       not have to be repeated (but if they are, they have to match;
       the same goes when overriding inherited methods)
  + allow specifying the external name of Objective-C classes and
    protocols, since classes and protocols can have the same name
    (and you cannot use the same Pascal identifier in such caseq)
  + added NSObject protocol, and make the NSObject class use it
  + added missing NSObject class methods that have the same name
    as instance methods (added "class" name prefix to avoid clashes)
  * fixed several cases where the compiler did not treat Objective-C
    classes/protocols the same as Object Pascal classes/interfaces
    (a.o., forward declarations, alignment, regvars, several type
     conversions, ...)
  * allow "override" directive in objcclass declarations, and print
    a hint if it's forgotten in an external declaration (because it
    doesn't really matter there, and may make automated header
    conversion harder than necessary) and an error if will be used in
    a non-external declaration (because it is not possible to start
    a new vmt entry-tree in Objective-C, you can only override parent
    methods)
  * reject objcclasses/protocols as parameters to typeof()
  * don't try to test VMT validity of objcclasses/protocols

b1b9894ae3 * initial Objective-C 1.0 support:
o support for declaring external Objective-C classes (see
      rtl/inc/objcbase.pas), including derived classes
    o support for converting methods of objcclasses into selectors
      (see tests/test/tobjc1.pp)
    o support for loading from/storing to fields of objcclasses
    o support for calling Objective-C methods using regular
      Object Pascal syntax (see tests/test/tobjc1.pp)
    o some things that are known to be not yet working:
      o automatic conversion from ID to objcclasses and back
      o declaring and implementing new objcclasses/methods in Pascal code
      o debug information (objcclasses are currently plain pointers
        as far as the debugger knows)

c1e327c8c4 * insert register allocation/deallocation information for the exception
handling code (g_exception_reason_load() now automatically allocates
    the cpu register that it loads). This fixes the bug reported in
    http://lists.freepascal.org/lists/fpc-devel/2009-May/016773.html
    on i386 with -O2)

e2b8792bd3 * do not initialize global reference-counted variables in the automatic

    value is not used (mantis #13536)

5cf4ab7642 * always initialize/finalize global refcounted variables in units, also

    may be used elsewhere, discovered while analyzing mantis #13345)

7d459cf12a * the compiler now explicitly keeps track of the minimally guaranteed
alignment for each memory reference (mantis #12137, and
    test/packages/fcl-registry/tregistry1.pp on sparc). This also
    enables better code generation for packed records in many cases.
  o several changes were made to the compiler to minimise the chances
    of accidentally forgetting to set the alignment of memory references
    in the future:
    - reference_reset*() now has an extra alignment parameter
    - location_reset() can now only be used for non LOC_(C)REFERENCE,
      use location_reset_ref() for those (split the tloc enum so the
      compiler can catch errors using range checking)

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)

a23630260b + "weakexternal" support for imported procedures and variables.
the syntax is exactly the same as for "external", except for
    the keyword. It is currently only active for Darwin targets.
    It should also work at least for Linux targets, but only with
    the GNU assembler (which is why it is not activated there)
  + test for this functionality

150eda304b * factored unix exports handling from t_bsd and t_linux into expunix unit
(todo: at least solaris, maybe others)
  * changed the "exports" section handling:
    a) make everything private which is not exported (implemented for
       darwin and linux)
    b) for the exported symbols:
     - functions/procedures
      1) if no name or index is provided, and if the procedure has aliases
         defined via the public/export directives, then export the default
         mangled name and all defined aliases
      2) otherwise if no name is specified (but there is an index) then
        i) if the procedure is defined as cdecl/cppdecl/mwpascal, use the
           appropriately mangled version of the function name
       ii) otherwise export the name without any mangling(e.g. "exports
           proc1" -> proc1 is the exported name)
     - variables
      1) if no name is provided and the variable was specified as cvar,
         use the mangled name
      2) otherwise if no name is provided, export the name without any
         mangling
  -> initialization/finalization of shared libraries under Linux works
     again (mantis #7838)
  -> sharing symbols between shared library and main program works
     under Linux (mantis #9089)

e1ec2834df * increase/decrease refcount of interface value parameters on procedure
entry/exit (mantis #10897)
  * fixed tinterface2 which crashed after this change. It also crashed under
    Kylix: you cannot assign the result of an interfaced class to a class
    instance variable and then use it both as an interface (refcounted) and
    as class (non-refcounted)

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)

0567329343 * the "external alignment" (i.e., that of their starting addresses) of
record variables is now independent of their packrecords setting
    (except for packrecords C, which already calculated a reasonable
    alignment). This means that e.g. a packed record consisting of two
    pointers will be aligned at sizeof(pointer) normally. The internal
    alignment of the individual fields of packed records obviously did
    not change, also not if those fields are records themselves.
  * The size of records without any packing atributes is also padded to
    become a multiple of this improved alignment calculation, which
    means that the size of such records may change after this patch.
    Always explicitly specify a packing for records which are used for
    data storage/transmission if you want to have a consistent layout.

b951947b64 * partially fixed Delphi compatibility for assembler procedures: in case
only parameters on the stack are passed and if the function result is
    not referenced, don't allocate a stackframe. Fixes mantis 8155, but
    see that bug report for other rules (there's one error there: Delphi
    *does* allocate a function result for non-string/variant/interface
    if @result is referenced)

eccbc78e04 + support for bitpacked arrays:
+ use {$bitpacking on/+} to change the meaning of "packed"
      into "bitpacked" for arrays. This is the default for MacPas.
      You can also define individual arrays as "bitpacked", but
      this is not encouraged since this keyword is not known by
      other compilers and therefore makes your code unportable.
    + pack(unpackedarray,index,packedarray) to pack
      length(packedarray) elements starting at
      unpackedarray[index] into packedarray.
    + unpack(packedarray,unpackedarray,index) to unpack
      packedarray into unpackedarray, with the first
      element being stored at unpackedarray[index]
  * todo:
    * "open packed arrays" and rtti for packed arrays are not
      yet supported
    * gdb does not properly support bitpacked arrays
