7cfd7a66cd + create a special 'heap' segment with reserved space equal to heapsize (i.e.
the value set by -Ch or the second parameter to the $M directive). This is
  equivalent to the heapmin value in Turbo Pascal 7 and ensures that the program
  has at least this amount of heap space available (otherwise DOS will show a
  'not enough memory' error and will refuse to load the program).

3cc8ff11e3 + generate the stack segment for i8086 far data memory models from within fpc
itself (instead of having a fixed 16k stack in the startup code). This allows
  setting the stack size in these models with the -Cs option.

ac43eb9b70 + generic implementation of ReplaceForbiddenAsmSymbolChars() instead
of the AVR-specific ifdef'ed variant
   o since the only special character we use in mangled names on all platforms
     is $, added a new field to tasminfo called "dollarsign" that holds the
     character $'s should be replaced with (if it doesn't have to be replaced,
     leave it at $)

4838ebe73b * renamed mark_InlineStart/mark_InlineEnd to mark_NoLineinfoStart/
mark_NoLineinfoEnd
  * add "no line info" markers for try/except and try/finally internal cleanup
    code, so the debugger doesn't jump back and forth between the end and start
    of exception blocks when you arrive at the end
  * honour "no line info" markers in dbgdwarf.pas

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

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

59365a6db9 - garbage was being output sometimes instead of source lines when compiling with -al. This is because lastfileinfo and lastinfile were never initialized for MASM writer. This is true for TPPCMPWAssembler, too.
- long lines were not wrapped.
- constants of type ait_comp_64bit output incorrectly.
- at end of file, current segment was not closed.

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)
