* 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
git-svn-id: branches/objc@13763 -
* 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...

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

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)

* -Xg now produces a .dbg file with debuginfo
that can be used by gdb. The main executable gets
a debuglink section that references the .dbg file.

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)
git-svn-id: trunk@8650 -
* compiler version string is stored in .fpc.version section.
* debug start/end links are stored in .fpc.links section.
* fixed linking with eVC++ object files by internal linker.
* .fpc.links section is removed by internal linker before writing executable, because it is no longer needed.
