# Variables below this line are exceptions to the ABI changes
# 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
syscall_abi_change="fcntl ksem_init ksem_open mprotect msgsys semsys shmsys sigqueue sigreturn sysarch _umtx_lock _umtx_unlock _umtx_op"

# 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

# getkerninfo - obsolete and can't be implemented (kernel virtual addresses can't fit in 32-bits)

# Syscalls without implementations:
# __mac_* - should be implemented
# afs3_syscall - requires significant porting, probably doesn't make sense
# kldsym - can't be implemented (kernel virtual addresses can't fit in 32-bits)
# lgetfh - should be implemented
# nlm_syscall - requires significant porting, probably doesn't make sense
# nnpfs_syscall - requires significant porting, probably doesn't make sense
# ntp_gettime - should be implemented
# thr_create - was unimplemented and appears to be unnecessary
