From 4cc4b30426c5e5a0ecf912791e3f27312438d10e Mon Sep 17 00:00:00 2001 From: Bernhard Reutner-Fischer Date: Tue, 3 Jun 2008 08:11:56 +0000 Subject: - adds several config-options to allow for turning off certain features like o UCLIBC_HAS_GNU_ERROR o UCLIBC_HAS_BSD_ERR o UCLIBC_HAS_PTY o UCLIBC_HAS_GETPT (1) o UCLIBC_SYSCALL_STUBS o UCLIBC_SYSCALL_STUB_WARNING o UCLIBC_LINUX_SPECIFIC (2) o UCLIBC_BSD_SPECIFIC (3) o UCLIBC_NTP_LEGACY (4) o UCLIBC_SV4_DEPRECATED (5) o UCLIBC_HAVE_REALTIME (6) o UCLIBC_HAVE_ADVANCED_REALTIME (7) o UCLIBC_HAVE_EPOLL (8) o UCLIBC_HAVE_XATTR (9) o UCLIBC_HAVE_PROFILING (10) (1) make non-standard getpt optional and implement standard posix_openpt (2) fstatfs(), inotify_*(), ioperm(), iopl(), madvise(), modify_ldt(), personality() ppoll(), setresuid() (3) mincore(), getdomainname(), setdomainname() (4) ntp_adjtime(), ntp_gettime() aliases (5) ustat() [use statfs(2) in your code instead] (6) All marked as "(REALTIME)" in SUSv3 (7) All marked as "(ADVANCED REALTIME)" in SUSv3 (8) epoll_create(), epoll_ctl(), epoll_wait() (9) all Extended Attributes (10) helpers for gcc's -finstrument-functions - Fixes _dl_exit() - Implements sleep(3) for !UCLIBC_HAVE_REALTIME - Implements usleep(3) for !UCLIBC_HAVE_REALTIME - adds #warning about incorrect posix_fadvise{,64}() - removes unused and unwanted uselib() Net outcome is that an allnoconfig with HAVE_SHARED is now about 88k instead of formerly 130k. --- libc/misc/dirent/Makefile.in | 4 ++-- libc/misc/error/Makefile.in | 8 +++++++- libc/misc/error/err.c | 3 +++ libc/misc/statfs/fstatvfs.c | 18 ++++++++++++++++-- libc/misc/statfs/statvfs.c | 5 +++-- libc/misc/syslog/Makefile.in | 2 ++ libc/misc/sysvipc/sem.c | 6 ++++-- libc/misc/time/Makefile.in | 6 ++++-- 8 files changed, 41 insertions(+), 11 deletions(-) (limited to 'libc/misc') diff --git a/libc/misc/dirent/Makefile.in b/libc/misc/dirent/Makefile.in index 89a00ed5e..b35efa0b1 100644 --- a/libc/misc/dirent/Makefile.in +++ b/libc/misc/dirent/Makefile.in @@ -5,8 +5,8 @@ # Licensed under the LGPL v2.1, see the file COPYING.LIB in this tarball. # -CSRC := alphasort.c closedir.c dirfd.c opendir.c readdir.c rewinddir.c scandir.c \ - seekdir.c telldir.c readdir_r.c +CSRC := alphasort.c closedir.c dirfd.c opendir.c readdir.c rewinddir.c \ + scandir.c seekdir.c telldir.c readdir_r.c ifeq ($(UCLIBC_HAS_LFS),y) CSRC += readdir64.c alphasort64.c scandir64.c readdir64_r.c diff --git a/libc/misc/error/Makefile.in b/libc/misc/error/Makefile.in index c529e955e..9facacff0 100644 --- a/libc/misc/error/Makefile.in +++ b/libc/misc/error/Makefile.in @@ -5,7 +5,13 @@ # Licensed under the LGPL v2.1, see the file COPYING.LIB in this tarball. # -CSRC := error.c err.c +CSRC := +ifeq ($(UCLIBC_HAS_BSD_ERR),y) +CSRC += err.c +endif +ifeq ($(UCLIBC_HAS_GNU_ERROR),y) +CSRC += error.c +endif MISC_ERROR_DIR := $(top_srcdir)libc/misc/error MISC_ERROR_OUT := $(top_builddir)libc/misc/error diff --git a/libc/misc/error/err.c b/libc/misc/error/err.c index cd331500a..ab9c8b72b 100644 --- a/libc/misc/error/err.c +++ b/libc/misc/error/err.c @@ -19,6 +19,8 @@ #warning REMINDER: Deal with wide oriented stderr case. #endif +#if defined __USE_BSD + libc_hidden_proto(vwarn) libc_hidden_proto(vwarnx) libc_hidden_proto(verr) @@ -124,3 +126,4 @@ void attribute_noreturn errx(int status, const char *format, ...) while(1) va_end(args);
