- uart0.rt/.tx nonexistent file segment fault
Other modifications:
- replaced string names to instruction indexes
- execute.c executes specified (in ISA table) function
- modified ISA table - flag needed for gdb
- added or32.c, which supports or32.h
- added new instructions l.mac, l.msb, l.maci, l.macrc
and their executing functions (opcodes to be revisited)
- added header acconfig.h
- modified configuration files |
