0c675a4039 * the objc1 unit has been renamed to objc
* the objc unit links against the Foundation instead of against the Cocoa
    framework, and inludes an interface to either the fragile or non-fragile
    obj-c run time depending on the target platform
  + support for the non-fragile Objective-C runtime/ABI, as used on Mac OS X
    for ARM (iPhone) 64 bit (PowerPC/64, x86_64) -- all these targets now
    are now also supported for the objectivec1 modeswitch
  + support for private_extern symbol bindings, required for the above
  * mark objcclasses that are declared in the implementation section of a
    unit as "hidden" (not sure what the effect is, since the Objective-C
    runtime does not seem to do anything with this flag)
  * enabled all obj-c tests for the newly supported platforms

ec8fee45fe * do not access local data via the GOT on x86_64, because
a) it's unnecessary
   b) it's slower than "direct" RIP-relative accessing
   c) it's not supported on darwin/x86_64 in certain cases
  * never use absolute addressing on darwin/x86_64 (like on win64)
  * when not generating PIC, make sure that a_loadaddr_ref_reg on x86_64
    also uses RIP-relative addressing for darwin/x86_64 and win64

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

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)

    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)

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)

    o these types are now all signed
    o converting an integer type to a byte/word/long/qwordbool using an
      explicit type cast keeps the integer's original value stored in the
      bool, instead of forcing it to ord(true)/ord(false)
    (mantis #10233 and #10613, implemented for all architectures, testsuite
     tested for ppc32, sparc and x86)
  * fixed some places where the rtl depended on longbool(true) having the
    value 1
  * extended several boolean tests (and adapted some to no longer assume
    that byte/word/long/qwordbool(true)=1)
  + support for converting to qwordbool in second_int_to_bool for x86, ppc
