This is Jorand Didier's Motorola 68360 (sim68360) simulator. It doesn't contain all of the 68360 devices but it does provide a CPU32 based simulator.
Jorand actually uses (used) GCC and GDB to do development work with BSVC. For more information see the file bsvc/misc/sim68360/gcc-gdb.ps.
Here's a note about using the samples for sim68360:
Go in the sample/sim68360 directory and play with the tests: IMPORTANT: for that to work, you need to define 2 environment variables: BSVC, which contains the path to the 'bsvc' directory and 'M68K_LIB' which contains the path to the libgcc.a directory. It can look like '/usr/local/m68k/lib/gcc-lib/m68k-none-elf/4.9.2'. You've got everything to test gcc and gdb... enjoy.
The following instructions are not currently implemented in sim68360:
- CHK
- NBCD
- SBCD
