Detail:
  Added some debugging code to reroute, (assmebly time option) debug
  output through the HAL debug route. Has proved useful locating null
  pointer errors with vectors assembled high.

Version 1.75. Tagged as 'DDEUtils-1_75'

On a 26 bit system a call to DDE_ThrowbackSend internally uses common_handler_external_entry to expand the thrown filename with the task local prefix, sharing code with the various filing system vectors which are intercepted.
However, common_handler_external_entry looks up the stack at sp+4 to retrieve the entry flags that the vectors stack on entry, only DDE_ThrowbackSend didn't. The result was instead to read stacked R0 which is most often 1 to pass an error, then the TEQNEP would switch from SVC to FIQ mode, and an abort due to the banked registers pointed in the wrong place.

In the 26 bit case a fake return is now stacked (we want common_handler_external_entry to return in both cases whether or not a prefix is set) in SVC26 mode.
Tested on RISC OS 4.02 with the !ObjAsm front end setting a task local prefix.

Move throwback_add_prefix down to where it's used.
Escape some dollars in strings.

Version 1.72. Tagged as 'DDEUtils-1_72'

Detail:
  A missing ALIGN directive caused bit 0 of the offset to the *Prefix code
  to be set. On ARMv7, ALU instructions targetting the PC with bit 0 set
  causes a Thumb interworking branch to be taken, which isn't what you want.
  A number of LDM/STMs of single registers have also been optimised.

  Fix received from Willi Theiss

Version 1.71. Tagged as 'DDEUtils-1_71'

Version 1.70. Tagged as 'DDEUtils-1_70'

Various of OS_File, OS_Find, and OS_FSControl have subreasons which force the use of a path or path variable, which DDEUtils was not respecting. Fixes ticket #167.
Moved the ReadPrefix SWI code down with the other SWIs.
Moved the Prefix SWI code down with the other SWIs.
Moved 'strip_hats' next to 'strip_hats0'.
Added FSControl_InfoToFileType to the list of FSControl subreasons operated on.
Made the various SWI error exits use the common 'return_setv' so overall the module is smaller than in 1.66.

Version 1.69. Tagged as 'DDEUtils-1_69'

Two more hardwired constants swapped for defines.
Not tagged.

Now uses OS_ReadSysInfo 6 to get the address of the domain id.
Put the throwback subreasons into the exported constants.
Remove more of the hardwired constants.
Remove all occurences of LDMFD r13! {lr and pc together} cos ARM have deprecated it.

Version 1.68. Tagged as 'DDEUtils-1_68'

Line up code to more normal tab stops.
Add warning that it messes with zero page values.
Same size binary, but the "BadSWI" error number was wrong, so the binary differs.

Version 1.67. Tagged as 'DDEUtils-1_67'

Detail:
  * Some 32-bit unsafe instructions removed
  * Now runs on 26-bit systems again (passing on vectors branched to the
    wrong address!)
  * Added new SWI DDEUtils_FlushCL to allow a bugfix to system() in the
    shared C library
Admin:
  Tested on a 26-bit system.

Version 1.66. Tagged as 'DDEUtils-1_66'

No code changes.

Version 1.65. Tagged as 'DDEUtils-1_65'

Version 1.64. Tagged as 'DDEUtils-1_64'

Version 1.63. Tagged as 'DDEUtils-1_63'

Detail:
  DDEUtils does not really fit in System but should be its own component.
  It is now.
Admin:
  Exports a header that is required by the shared C library builds
    (currently only the one on the 32-bit branch)
  Version number incremented to 1.62
  Now uses srccommit for version number maintenance.
