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

29# System calls that require freebsd32-specific handling:
30# fcntl - need to sign extend arg unless it's a pointer
31# ksem_init, ksem_open - XXX not required
32# mprotect - i386 read-implies-exec
33# msgsys, semsys, shmsys - some sub-syscalls require compat
34# sigqueue - union sival requires special handing on big-endian
35# sigreturn - struct osigcontext
36# sysarch - always MD
37# _umtx_lock _umtx_unlock _umtx_op - arguments require special handling
38syscall_abi_change="fcntl ksem_init ksem_open mprotect msgsys semsys shmsys sigqueue sigreturn sysarch _umtx_lock _umtx_unlock _umtx_op"

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

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

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