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

27# System calls that require freebsd32-specific handling:
28# fcntl - need to sign extend arg unless it's a pointer
29# ksem_init, ksem_open - XXX not required
30# mprotect - i386 read-implies-exec
31# msgsys, semsys, shmsys - some sub-syscalls require compat
32# sigqueue - union sival requires special handing on big-endian
33# sigreturn - struct osigcontext
34# sysarch - always MD
35# _umtx_lock _umtx_unlock _umtx_op - arguments require special handling
36syscall_abi_change="fcntl ksem_init ksem_open mprotect msgsys semsys shmsys sigqueue sigreturn sysarch _umtx_lock _umtx_unlock _umtx_op"
37
38# System calls that appear to require handling, but don't:
39# aio_cancel - the aiocb pointer is just a virtual address
40# thr_* - the lack of sign extension of long args is OK
41# sctp_generic_* - iovec differences handled internally

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

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