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

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

34c985cfa6 * added register type parameter to cgsize2subreg(), as the subreg can
depend on that (and correct a number of cases where this was wrong)
  * set the correct subreg type for xmm x86_64 parameter registers
    (resolved mantis #14067)

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

263984f874 * fixed a_load_ref_reg for OS_S8->OS_16 for ppc32, ppc64 and sparc
(and on ppc64 also for OS_S8->OS_32 and OS_S16->OS_32)
  * adapted tcnvint6 to check for ppc64 OS_S16->OS_32 conversion
    (the old comparison was performed using a 32 bit compare and
     therefore did not notice the wrong result)

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)

4e60ceb237 * removed code which splits "unaligned" 8 byte stores/loads into two 4 bytes stores/loads on ppc64. The processor manuals and extensive testing showed that PPC970+ class processors have hardware assisted handling of unaligned memory accesses, which results in 8 byte memory accesses to be always faster than 4 byte ones
