22# Variables below this line are exceptions to the ABI changes programatically
23# detected by makesyscalls.lua.  New system calls should not require an entry
24# here in nearly virtually all cases.  New entries are almost certainly
25# representative of badly designed interfaces.

28# System calls that require freebsd32-specific handling:
29# fcntl - need to sign extend arg unless it's a pointer
30# ksem_init, ksem_open - XXX not required
31# mprotect - i386 read-implies-exec
32# msgsys, semsys, shmsys - some sub-syscalls require compat
33# sigqueue - union sival requires special handing on big-endian
34# sigreturn - struct osigcontext
35# sysarch - always MD
36# _umtx_lock _umtx_unlock _umtx_op - arguments require special handling
37syscall_abi_change="fcntl ksem_init ksem_open mprotect msgsys semsys shmsys sigqueue sigreturn sysarch _umtx_lock _umtx_unlock _umtx_op"

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

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

49# Syscalls without implementations:
50# *mac_* - should be implemented
51# afs3_syscall - requires significant porting, probably doesn't make sense
52# kldsym - can't be implemented (kernel virtual addresses can't fit in 32-bits)
53# lgetfh - should be implemented
54# nlm_syscall - requires significant porting, probably doesn't make sense
55# nnpfs_syscall - requires significant porting, probably doesn't make sense
56# ntp_gettime - should be implemented
57# thr_create - was unimplemented and appears to be unnecessicary
