Or you may use some simulator with GDB support. gdb/ChangeLog: * Makefile.in (ALL_TARGET_OBS): Add z80-tdep.c. * NEWS: Mention z80 support. * configure.tgt: Handle z80*. * features/Makefile (XMLTOC): Add z80.xml. * features/z80-cpu.xml: New. * features/z80.c: Generate. * features/z80.xml: New. * z80-tdep.c: New file. * z80-tdep.h: New file. gdb/stubs/ChangeLog: * z80-stub.c: New file.
