ChangeLog 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. VEA Missing VEA system calls. ppc-instructions: Missing or commented out instructions. 64bit: 64bit target untested. 64bit host broken. For instance use of scanf "%x", &long long. events.c: Event code for pending events from within signal handlers not finished/tested. hw_*.c: 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. device_ioctl(): Should have an extra argument (unsigned request) as standard.
