From c647fb885cb678471f6b6a66f394b4ca5515a016 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Mon, 3 Jul 2017 14:39:52 -0300 Subject: Consolidate non cancellable write call This patch consolidates all the non cancellable write calls to use the __write_nocancel identifier. For non cancellable targets it will be just a macro to call the default respective symbol while on Linux will be a internal one. Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu. * sysdeps/generic/not-cancel.h (write_not_cancel): Remove macro. (__write_nocancel): New macro. * sysdeps/unix/sysv/linux/not-cancel.h (__write_nocancel): Rewrite as a function prototype. (write_not_cancel): Remove macro. * sysdeps/unix/sysv/linux/write.c (__write_nocancel): New function. * gmon/gmon.c (ERR): Replace write_not_cancel with __write_nocancel. (write_gmon): Likewise. * libio/fileops.c (_IO_new_file_write): Likewise. * login/utmp_file.c (pututline_file): Likewise. (updwtmp_file): Likewise. * stdio-common/psiginfo.c (psiginfo): Likewise. * sysdeps/posix/spawni.c (__spawni_child): Likewise. * sysdeps/unix/sysv/linux/gethostid.c (sethostid): Likewise. * sysdeps/unix/sysv/linux/libc_fatal.c (backtrace_and_maps): Likewise. * sysdeps/unix/sysv/linux/pthread_setname.c (pthread_setname_np): Likewise. --- gmon/gmon.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'gmon') diff --git a/gmon/gmon.c b/gmon/gmon.c index 87c3c4e01b..e7701b9757 100644 --- a/gmon/gmon.c +++ b/gmon/gmon.c @@ -58,7 +58,7 @@ struct gmonparam _gmonparam attribute_hidden = { GMON_PROF_OFF }; static int s_scale; #define SCALE_1_TO_1 0x10000L -#define ERR(s) write_not_cancel (STDERR_FILENO, s, sizeof (s) - 1) +#define ERR(s) __write_nocancel (STDERR_FILENO, s, sizeof (s) - 1) void moncontrol (int mode); void __moncontrol (int mode); @@ -375,7 +375,7 @@ write_gmon (void) memcpy (&ghdr.cookie[0], GMON_MAGIC, sizeof (ghdr.cookie)); ghdr.version = GMON_VERSION; memset (ghdr.spare, '\0', sizeof (ghdr.spare)); - write_not_cancel (fd, &ghdr, sizeof (struct gmon_hdr)); + __write_nocancel (fd, &ghdr, sizeof (struct gmon_hdr)); /* write PC histogram: */ write_hist (fd); -- cgit 1.4.1
