From 2f8033d6067fff3e7d77bb2174a9564bd7199cea Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sat, 1 Apr 1995 09:01:49 +0000 Subject: [PATCH] Sat Apr 1 00:08:06 1995 Roland McGrath * locale/loadlocale.c (_nl_load_locale) [MAP_FILE]: Define it zero if undefined. * string/strxfrm.c: Just copy the string (for now). * string/strcoll.c: Just call strcmp (for now). * mach/Makefile (lock): Add mutex-init. * mach/mutex-solid.c (_cthread_mutex_lock_routine, _cthread_mutex_unlock_routine): Variables removed. (__mutex_lock_solid, __mutex_unlock_solid): Don't use them; just stub. (__mutex_init): Function moved to new file mutex-init.c. * mach/mutex-init.c: New file, broken out of mutex-solid.c. --- ChangeLog | 15 +++++++++++++++ locale/loadlocale.c | 4 ++++ mach/Makefile | 2 +- mach/mutex-solid.c | 27 +++++++-------------------- string/strcoll.c | 48 ++++++------------------------------------------ string/strxfrm.c | 52 ++++++---------------------------------------------- 6 files changed, 39 insertions(+), 109 deletions(-) diff --git a/ChangeLog b/ChangeLog index 3d23dc9..9b3e48a 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,18 @@ +Sat Apr 1 00:08:06 1995 Roland McGrath + + * locale/loadlocale.c (_nl_load_locale) [MAP_FILE]: Define it zero + if undefined. + + * string/strxfrm.c: Just copy the string (for now). + * string/strcoll.c: Just call strcmp (for now). + + * mach/Makefile (lock): Add mutex-init. + * mach/mutex-solid.c (_cthread_mutex_lock_routine, + _cthread_mutex_unlock_routine): Variables removed. + (__mutex_lock_solid, __mutex_unlock_solid): Don't use them; just stub. + (__mutex_init): Function moved to new file mutex-init.c. + * mach/mutex-init.c: New file, broken out of mutex-solid.c. + Thu Mar 30 20:43:02 1995 Brendan Kehoe * sysdeps/mips/__longjmp.c (__longjmp): Take out CONST. diff --git a/locale/loadlocale.c b/locale/loadlocale.c index 8066fbb..f3e8e4a 100644 --- a/locale/loadlocale.c +++ b/locale/loadlocale.c @@ -102,6 +102,10 @@ _nl_load_locale (int category, char **name) /* Linux seems to lack read-only copy-on-write. */ #define MAP_COPY MAP_PRIVATE #endif +#ifndef MAP_FILE + /* Some systems do not have this flag; it is superfluous. */ +#define MAP_FILE 0 +#endif filedata = (void *) __mmap ((caddr_t) 0, st.st_size, PROT_READ, MAP_FILE|MAP_COPY, fd, 0); if (filedata == (void *) -1) diff --git a/mach/Makefile b/mach/Makefile index 3a7a8fe..509785c 100644 --- a/mach/Makefile +++ b/mach/Makefile @@ -28,7 +28,7 @@ headers = mach_init.h mach.h mach_error.h mach-shortcuts.h mach/mach_traps.h \ $(interface-headers) mach/mach.h mach/mig_support.h mach/error.h \ $(lock-headers) machine-sp.h distribute = thread_state.h -lock = spin-solid spin-lock mutex-solid +lock = spin-solid spin-lock mutex-init mutex-solid lock-headers = lock-intern.h machine-lock.h spin-lock.h routines = $(mach-syscalls) $(mach-shortcuts) \ mach_init mig_strncpy msg \ diff --git a/mach/mutex-solid.c b/mach/mutex-solid.c index aeaa269..db203d9 100644 --- a/mach/mutex-solid.c +++ b/mach/mutex-solid.c @@ -1,4 +1,5 @@ -/* Copyright (C) 1994 Free Software Foundation, Inc. +/* Stub versions of mutex_lock_solid/mutex_unlock_solid for no -lthreads. +Copyright (C) 1995 Free Software Foundation, Inc.
