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. --- librt/Makefile.in | 5 ++++- librt/mq_receive.c | 1 + librt/mq_send.c | 1 + 3 files changed, 6 insertions(+), 1 deletion(-) (limited to 'librt') diff --git a/librt/Makefile.in b/librt/Makefile.in index f6433d30b..c91552acc 100644 --- a/librt/Makefile.in +++ b/librt/Makefile.in @@ -16,6 +16,7 @@ librt_FULL_NAME := librt-$(VERSION).so librt_DIR := $(top_srcdir)librt librt_OUT := $(top_builddir)librt +ifeq ($(UCLIBC_HAS_REALTIME),y) librt_SRC := $(wildcard $(librt_DIR)/*.c) librt_OBJ := $(patsubst $(librt_DIR)/%.c,$(librt_OUT)/%.o,$(librt_SRC)) @@ -28,7 +29,7 @@ librt-so-y += $(librt_OBJ:.o=.os) lib-a-y += $(top_builddir)lib/librt.a lib-so-y += $(top_builddir)lib/librt.so -objclean-y += librt_clean +endif ifeq ($(DOPIC),y) $(top_builddir)lib/librt.so: $(top_builddir)lib/librt.a $(libc.depend) @@ -48,5 +49,7 @@ $(top_builddir)lib/librt.a: $(librt-a-y) $(do_strip) $(do_ar) +objclean-y += librt_clean + librt_clean: $(RM) $(librt_OUT)/*.{o,os,a} diff --git a/librt/mq_receive.c b/librt/mq_receive.c index fa48426b9..276b1f573 100644 --- a/librt/mq_receive.c +++ b/librt/mq_receive.c @@ -6,6 +6,7 @@ #include #include #include +#warning FIXME: hard dependency on ADVANCED REALTIME feature librt_hidden_proto(mq_timedreceive) #ifdef __NR_mq_timedreceive diff --git a/librt/mq_send.c b/librt/mq_send.c index ee2af4454..fbfc99e46 100644 --- a/librt/mq_send.c +++ b/librt/mq_send.c @@ -6,6 +6,7 @@ #include #include #include +#warning FIXME: hard dependency on ADVANCED REALTIME feature librt_hidden_proto(mq_timedsend) #ifdef __NR_mq_timedsend -- cgit v1.2.3
