178dab45d3 + added new asm directive 'asd_cpu' (specifies the CPU's instruction set) in the
compiler's internal assembly representation. It is not yet generated by the
  compiler and is only implemented properly in the NASM writer (but will
  eventually be implemented in the other assembler writers as well, including
  the internal assembler). In the future, it is intended to allow:
  1) catching instructions, generated by the compiler and not supported by the
     target CPU, due to a bug in the code generator
  2) allowing a different instruction set to be used in inline asm blocks (I'm
     planning a new directive for that - {$asmcpu XXX}), because the code
     generator will be able to switch target CPU in the middle of the asm output
     stream

991e1f49bd * store a pointer to the used tasminfo record in every assembler writer, so

    in LLVM IR)

b3d0197f98 * factored out the output file handling (mostly writing data) from the

b0ff41406a * grouped all tai_real* types into a single tai_realconst type,
to free up space for more ait_* types in taitype (can't have
    more than 32 because they have to fit in a small set)
   o factored out writing of floating point numbers as an array of
     byte in the external assemblers

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.

14cfe770a4 * replaced most (if not all) remaining fields/parameters in the compiler

    1% extra memory usage)

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 $)

4c21beb48e win64 unwinding, misc fixes:
* Insert seh_endprologue directive after the last prologue instruction, not before it
* Omit seh_stackalloc for zero bytes
* (For now) ignore SEH directives in NASM and MASM writers, instead of failing with internal error.

34ffb184a8 * MASM and NASM assembler writers, added check for InlineLevel>0 so it suppresses entire source file processing, not just output of source lines. Without this, auto-generated instructions cause output of bogus line information. GAS writer already has similar check.

    code, so the debugger doesn't jump back and forth between the end and start
    of exception blocks when you arrive at the end

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

      unit

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
