   3 See the ChangeLog file looking for lines taged with the word FIXME.
   4
   5 COREFILE.C:
   6
   7 The implementation of corefile.c (defined by corefile.h) isn't the
   8 best.  It is intended to be functionaly correct rather than fast.  One
   9 option being considered is to add a data cache to reduce the overhead
  10 of the most common case of data read/writes.
  11
  12 VEA
  13
  14 Missing VEA system calls.
  15
  16 ppc-instructions:
  17
  18 Missing or commented out instructions.
  19
  20 64bit:
  21
  22 64bit target untested. 64bit host broken.  For instance use of scanf
  23 "%x", &long long.
  24
  25 events.c:
  26
  27 Event code for pending events from within signal handlers not
  28 finished/tested.
  29
  30 hw_*.c:
  31
  32 Better and more devices.
  33
  34 PORTABILITY:
  35
  36 (Notes taken from Michael Meissner): Heavy use of the ## operator -
  37 fix using the clasic X/**/Y hack; Use of the signed keyword.  In
  38 particular, signed char has no analogue in classic C (though most
  39 implementations of classic C use signed chars); Use of long long which
  40 restricts the target compiler to be GCC.
  41
  42
  43 device_ioctl():
  44
  45 Should have an extra argument (unsigned request) as standard.
