From: gdbadmin Date: Wed, 1 Sep 2010 01:53:43 +0000 (+0000) Subject: use xsnprintf instead of snprintf. X-Git-Tag: sid-snapshot-20100901~6 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6cebaf6e1ae4a9f02d9d9136fccbab1ef06b1b6e;p=platform%2Fupstream%2Fbinutils.git use xsnprintf instead of snprintf. snprintf is not available on LynxOS, so I changed the calls to snprintf to calls to xsnprintf, which should be strictly equivalent. gdb/gdbserver/ChangeLog: * utils.c (xsnprintf): Make non-static. * server.h: Add xsnprintf declaration. * linux-low.c, nto-low.c, target.c, thread-db.c, tracepoint.c: replace calls to snprintf by calls to xsnprintf throughout. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index add04e6..870ee54 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,12 @@ 2010-09-01 Joel Brobecker + * utils.c (xsnprintf): Make non-static. + * server.h: Add xsnprintf declaration. + * linux-low.c, nto-low.c, target.c, thread-db.c, tracepoint.c: + replace calls to snprintf by calls to xsnprintf throughout. + +2010-09-01 Joel Brobecker + * configure.ac: Add configure check for alloca. * configure, config.in: Regenerate. * server.h: Include alloca.h if it exists. diff --git a/gdb/gdbserver/linux-low.c b/gdb/gdbserver/linux-low.c index 714dac3..f2177ff 100644 --- a/gdb/gdbserver/linux-low.c +++ b/gdb/gdbserver/linux-low.c @@ -4310,7 +4310,7 @@ linux_read_auxv (CORE_ADDR offset, unsigned char *myaddr, unsigned int len) int fd, n; int pid = lwpid_of (get_thread_lwp (current_inferior)); - snprintf (filename, sizeof filename, "/proc/%d/auxv", pid); + xsnprintf (filename, sizeof filename, "/proc/%d/auxv", pid); fd = open (filename, O_RDONLY); if (fd < 0) diff --git a/gdb/gdbserver/nto-low.c b/gdb/gdbserver/nto-low.c index 0c54b90..e094e28 100644 --- a/gdb/gdbserver/nto-low.c +++ b/gdb/gdbserver/nto-low.c @@ -174,7 +174,7 @@ do_attach (pid_t pid) close (nto_inferior.ctl_fd); init_nto_inferior (&nto_inferior); } - snprintf (nto_inferior.nto_procfs_path, PATH_MAX - 1, "/proc/%d/as", pid); + xsnprintf (nto_inferior.nto_procfs_path, PATH_MAX - 1, "/proc/%d/as", pid); nto_inferior.ctl_fd = open (nto_inferior.nto_procfs_path, O_RDWR); if (nto_inferior.ctl_fd == -1) { diff --git a/gdb/gdbserver/server.h b/gdb/gdbserver/server.h index b401960..286c80a 100644 --- a/gdb/gdbserver/server.h +++ b/gdb/gdbserver/server.h @@ -473,6 +473,8 @@ void *xmalloc (size_t) ATTR_MALLOC; void *xrealloc (void *, size_t); void *xcalloc (size_t, size_t) ATTR_MALLOC; char *xstrdup (const char *) ATTR_MALLOC; +int xsnprintf (char *str, size_t size, const char *format, ...) + ATTR_FORMAT (printf, 3, 4);; void freeargv (char **argv); void perror_with_name (const char *string); void error (const char *string,...)
