From 21340f30b3b095c29e40dbb7a9789b599a246f7e Mon Sep 17 00:00:00 2001 From: marcel Date: Sun, 9 Nov 2003 20:31:04 +0000 Subject: Change the clear_ret argument of get_mcontext() to be a flags argument. Since all callers either passed 0 or 1 for clear_ret, define bit 0 in the flags for use as clear_ret. Reserve bits 1, 2 and 3 for use by MI code for possible (but unlikely) future use. The remaining bits are for use by MD code. This change is triggered by a need on ia64 to have another knob for get_mcontext(). --- sys/kern/kern_context.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'sys/kern/kern_context.c') diff --git a/sys/kern/kern_context.c b/sys/kern/kern_context.c index ca3e2b1..300b1f4 100644 --- a/sys/kern/kern_context.c +++ b/sys/kern/kern_context.c @@ -70,7 +70,7 @@ getcontext(struct thread *td, struct getcontext_args *uap) if (uap->ucp == NULL) ret = EINVAL; else { - get_mcontext(td, &uc.uc_mcontext, 1); + get_mcontext(td, &uc.uc_mcontext, GET_MC_CLEAR_RET); PROC_LOCK(td->td_proc); uc.uc_sigmask = td->td_sigmask; PROC_UNLOCK(td->td_proc); @@ -114,7 +114,7 @@ swapcontext(struct thread *td, struct swapcontext_args *uap) if (uap->oucp == NULL || uap->ucp == NULL) ret = EINVAL; else { - get_mcontext(td, &uc.uc_mcontext, 1); + get_mcontext(td, &uc.uc_mcontext, GET_MC_CLEAR_RET); PROC_LOCK(td->td_proc); uc.uc_sigmask = td->td_sigmask; PROC_UNLOCK(td->td_proc); -- cgit v1.1
