 # Helper defines and macros for toolkit applications
 /**
  * Avoid creating macros / functions that overwrite registers (see the
  * GetLongPath macro for one way to avoid this)!
  *
  * Before using the registers exchange the passed in params and save existing
  * register values to the stack.
  *
  * Exch $R9 ; exhange the original $R9 with the top of the stack
  * Exch 1   ; exchange the top of the stack with 1 below the top of the stack
  * Exch $R8 ; exchange the original $R8 with the top of the stack
  * Exch 2   ; exchange the top of the stack with 2 below the top of the stack
  * Exch $R7 ; exchange the original $R7 with the top of the stack
  * Push $R6 ; push the original $R6 onto the top of the stack
  * Push $R5 ; push the original $R5 onto the top of the stack
  * Push $R4 ; push the original $R4 onto the top of the stack
  *
  * <do stuff>
  *
  * ; Restore the values.
  * Pop $R4  ; restore the value for $R4 from the top of the stack
  * Pop $R5  ; restore the value for $R5 from the top of the stack
  * Pop $R6  ; restore the value for $R6 from the top of the stack
  * Exch $R7 ; exchange the new $R7 value with the top of the stack
  * Exch 2   ; exchange the top of the stack with 2 below the top of the stack
  * Exch $R8 ; exchange the new $R8 value with the top of the stack
  * Exch 1   ; exchange the top of the stack with 2 below the top of the stack
  * Exch $R9 ; exchange the new $R9 value with the top of the stack
  *
  *
  * When inserting macros in common.nsh from another macro in common.nsh that
  * can be used from the uninstaller _MOZFUNC_UN will be undefined when it is
  * inserted. Use the following to redefine _MOZFUNC_UN with its original value
  * (see the RegCleanMain macro for an example).
  *
  * !define _MOZFUNC_UN_TMP ${_MOZFUNC_UN}
  * !insertmacro ${_MOZFUNC_UN_TMP}FileJoin
  * !insertmacro ${_MOZFUNC_UN_TMP}LineFind
  * !insertmacro ${_MOZFUNC_UN_TMP}TextCompareNoDetails
  * !insertmacro ${_MOZFUNC_UN_TMP}TrimNewLines
  * !undef _MOZFUNC_UN
  * !define _MOZFUNC_UN ${_MOZFUNC_UN_TMP}
  * !undef _MOZFUNC_UN_TMP

 # Macros for handling files in use
 /**
  * Checks for files in use in the $INSTDIR directory. To check files in
  * sub-directories this macro would need to be rewritten to create
  * sub-directories in the temporary directory used to backup the files that are
  * checked.
  *
  * Example usage:
  *
  *  ; The first string to be pushed onto the stack MUST be "end" to indicate
  *  ; that there are no more files in the $INSTDIR directory to check.
  *  Push "end"
  *  Push "freebl3.dll"

  *  ; macro will return after the first check.
  *  Push "${FileMainEXE}"
  *  ${CheckForFilesInUse} $R9
  *
  * !IMPORTANT - this macro uses the $R7, $R8, and $R9 registers and makes no
  *              attempt to restore their original values.
  *
  * @return  _RESULT
  *          false if all of the files popped from the stack are not in use.
  *          True if any of the files popped from the stack are in use.
  * $R7 = Temporary backup directory where the files will be copied to.
  * $R8 = value popped from the stack. This will either be a file name for a file
  *       in the $INSTDIR directory or "end" to indicate that there are no
  *       additional files to check.
