The included README talks about:
setup_process_readv_simple
setup_process_readv_iovec
setup_process_writev
while the actual test executables are called:
setup_process_vm_readv_simple
setup_process_vm_readv_iovec
setup_process_vm_writev
On m68k (ARAnyM), the first and third test succeed. The second one
fails, though:
# Setting up target with num iovecs 10, test buffer size 100000
Target process is setup
Run the following to test:
./t_process_vm_readv_iovec 1574 10 0x800030b0 89 0x80003110 38302
0x8000c6b8 22423 0x80011e58 18864 0x80016810 583 0x80016a60 8054
0x800189e0 3417 0x80019740 368 0x800198b8 897 0x80019c40 7003
and in the other window:
# ./t_process_vm_readv_iovec 1574 10 0x800030b0 89 0x80003110 38302
0x8000c6b8 22423 0x80011e58 18864 0x80016810 583 0x80016a60 8054
0x800189e0 3417 0x80019740 368 0x800198b8 897 0x80019c40 7003
copy_from_process failed: Invalid argument
error code: 29

Any suggestions?
