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

40# System calls that appear to require handling, but don't:
41# aio_cancel - the aiocb pointer is just a virtual address
