See the ChangeLog file looking for lines taged with the word FIXME.
COREFILE.C: The implementation of corefile.c (defined by
corefile.h) isn't the best. It is intended to be functionaly
correct rather than fast. One option being considered
is to add a data cache to reduce the overhead of the most
common case of data read/writes.
HTAB (page) code for OEA model untested. Some of the vm code
instructions unimplemented.
Lacks PowerOpen (a.k.a. XCOFF a.k.a. AIX) and NT startups. The
PowerOpen worked until I added the ELF one.
Missing VEA system calls.
Missing or commented out instructions.
64bit target untested.
64bit host broken. For instance use of scanf "%x", &long long.
Event code for pending events from within signal handlers not
finished/tested.
Better and more devices.
PORTABILITY (Notes taken from Michael Meissner): Heavy use of the ##
operator - fix using the clasic X/**/Y hack; Use of the signed
keyword. In particular, signed char has no analogue in classic C
(though most implementations of classic C use signed chars); Use of
long long which restricts the target compiler to be GCC.
