5cd83b26d9 * More proper check for executable image size limits. 
* Proper handling of 64-bit COFF relocations.
* Use jumps with 32-bit relative addressing in imports on win64.
* This fixes are related to bug #13657. The bug is not fully fixed yet...

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

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)

70c2414daa * split off sec_rodata_norel from sec_rodata, and only put constant data 
without relocations in sec_rodata_norel. It should be possible to make
    this new section read-only on all platforms, although currently it
    is only done for darwin, and for non-pic code written using the
    -Aas assembler writer.

    Most platforms also have a special section for "constant but with
    relocations" data, but such a section is currently only used for
    Darwin (others still use plain .data sections for that, like they
    did before)
