The branch main has been updated by kevans: URL: https://cgit.FreeBSD.org/src/commit/?id=e3707726c168eeb0ba06d13873dd71590b77d604 commit e3707726c168eeb0ba06d13873dd71590b77d604 Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2021-07-29 03:18:13 +0000 Commit: Kyle Evans <kevans@FreeBSD.org> CommitDate: 2021-07-29 03:22:23 +0000 kern: remove deprecated makesyscalls.sh makesyscalls was rewritten in Lua and introduced in d3276301ab. In the time since, no objections have risen and a warning was introduced long ago on invocation of makesyscalls.sh that it would be removed before FreeBSD 13. Belatedly follow through on that. --- sys/kern/makesyscalls.sh | 805 ----------------------------------------------- 1 file changed, 805 deletions(-) diff --git a/sys/kern/makesyscalls.sh b/sys/kern/makesyscalls.sh deleted file mode 100644 index 8cbd00a69fcd..000000000000 --- a/sys/kern/makesyscalls.sh +++ /dev/null @@ -1,805 +0,0 @@ -#! /bin/sh - -# @(#)makesyscalls.sh 8.1 (Berkeley) 6/10/93 -# $FreeBSD$ - -set -e - -# name of compat options: -compat=COMPAT_43 -compat4=COMPAT_FREEBSD4 -compat6=COMPAT_FREEBSD6 -compat7=COMPAT_FREEBSD7 -compat10=COMPAT_FREEBSD10 -compat11=COMPAT_FREEBSD11 -compat12=COMPAT_FREEBSD12 - -# output files: -sysnames="syscalls.c" -sysproto="../sys/sysproto.h" -sysproto_h=_SYS_SYSPROTO_H_ -syshdr="../sys/syscall.h" -sysmk="../sys/syscall.mk" -syssw="init_sysent.c" -syscallprefix="SYS_" -switchname="sysent" -namesname="syscallnames" -systrace="systrace_args.c" - -# tmp files: -sysaue="sysent.aue.$$" -sysdcl="sysent.dcl.$$" -syscompat="sysent.compat.$$" -syscompatdcl="sysent.compatdcl.$$" -syscompat4="sysent.compat4.$$" -syscompat4dcl="sysent.compat4dcl.$$" -syscompat6="sysent.compat6.$$" -syscompat6dcl="sysent.compat6dcl.$$" -syscompat7="sysent.compat7.$$" -syscompat7dcl="sysent.compat7dcl.$$" -syscompat10="sysent.compat10.$$" -syscompat10dcl="sysent.compat10dcl.$$" -syscompat11="sysent.compat11.$$" -syscompat11dcl="sysent.compat11dcl.$$" -syscompat12="sysent.compat12.$$" -syscompat12dcl="sysent.compat12dcl.$$" -sysent="sysent.switch.$$" -sysinc="sysinc.switch.$$" -sysarg="sysarg.switch.$$" -sysprotoend="sysprotoend.$$" -systracetmp="systrace.$$" -systraceret="systraceret.$$" -capabilities_conf="capabilities.conf" - -trap "rm $sysaue $sysdcl $syscompat $syscompatdcl $syscompat4 $syscompat4dcl $syscompat6 $syscompat6dcl $syscompat7 $syscompat7dcl $syscompat10 $syscompat10dcl $syscompat11 $syscompat11dcl $syscompat12 $syscompat12dcl $sysent $sysinc $sysarg $sysprotoend $systracetmp $systraceret" 0 - -touch $sysaue $sysdcl $syscompat $syscompatdcl $syscompat4 $syscompat4dcl $syscompat6 $syscompat6dcl $syscompat7 $syscompat7dcl $syscompat10 $syscompat10dcl $syscompat11 $syscompat11dcl $syscompat12 $syscompat12dcl $sysent $sysinc $sysarg $sysprotoend $systracetmp $systraceret - -case $# in - 0) echo "usage: $0 input-file <config-file>" 1>&2 - exit 1 - ;; -esac - -1>&2 echo "$0: This script has been replaced by sys/tools/makesyscalls.lua and" -1>&2 echo "$0: will be removed before FreeBSD 13.
