# programmatically detected by sys/tools/syscalls.  New system calls
# should not require an entry here in virtually all cases.  New entries
# are almost certainly representative of badly designed interfaces.

# System calls that require freebsd32-specific handling:
# fcntl - need to sign extend arg unless it's a pointer
# ksem_init, ksem_open - XXX not required
# mprotect - i386 read-implies-exec
# msgsys, semsys, shmsys - some sub-syscalls require compat
# sigqueue - union sival requires special handing on big-endian
# sigreturn - struct osigcontext
# sysarch - always MD
# _umtx_lock _umtx_unlock _umtx_op - arguments require special handling

# System calls that appear to require handling, but don't:
# aio_cancel - the aiocb pointer is just a virtual address
# thr_* - the lack of sign extension of long args is OK
# sctp_generic_* - iovec differences handled internally
