From 880f421fc30003d1626429e8796d43b91d71cab9 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 16 Feb 1998 17:42:46 +0000 Subject: Update. 1998-02-16 17:33 Ulrich Drepper * elf/rtld.c (dl_main): Recognize --library-path parameter and pass value (or NULL) to _dl_init_paths. * elf/dl-load.c (_dl_init_paths): Change to take one parameter, replacing local variable llp. If llp is NULL examine LD_LIBRARY_PATH environment variable. * elf/link.h: Change prototype for _dl_init_paths. * elf/dl-support.c: Pass NULL in _dl_init_paths call. * localedata/Makefile (distribute): Add test files. 1998-02-17 Andreas Jaeger * localedata/tests/{test1.cm, test2.cm, test3.cm, test4.cm, test1.def, test2.def, test3.def, test4.def}: Simple input files for localedef. Contributed by Yung-Ching Hsiao . * localedata/Makefile (tests): Call tst-locale.sh. * localedata/tst-locale.sh: New file, regression tests for some localedef problems. 1998-02-15 Thorsten Kukuk * nis/nss_nisplus/nisplus-alias.c: Use __stpncpy. * nis/nss_nisplus/nisplus-hosts.c: Make sure buffer is always NUL terminated. * nis/nss_nisplus/nisplus-network.c: Likewise. * nis/nss_nisplus/nisplus-proto.c: Likewise. * nis/nss_nisplus/nisplus-rpc.c: Likewise. * nis/nss_nisplus/nisplus-service.c: Likewise. Add more changes from TI-RPC 2.3 for rpcgen to fix include/C++ bug and support generating thread safe RPC code. * sunrpc/rpc_main.c: Add changes. * sunrpc/rpc_clntout.c: Likewise. * sunrpc/rpc_cout.c: Likewise. * sunrpc/rpc_hout.c: Likewise. * sunrpc/rpc_parse.c: Likewise. * sunrpc/rpc_sample.c: Likewise. * sunrpc/rpc_scan.c: Likewise. * sunrpc/rpc_svcout.c: Likewise. * sunrpc/rpc_util.c: Likewise. * sunrpc/rpc_util.h: Add new structs and prototypes. * sunrpc/proto.h: Remove prototypes for static functions. 1998-02-15 Andreas Schwab * locale/programs/ld-messages.c (messages_finish): Don't skip error checking when being quiet. * locale/programs/ld-ctype.c (ctype_finish): Likewise. (set_class_defaults): Likewise. * locale/programs/charmap.c (parse_charmap): Likewise. * locale/programs/ld-collate.c (collate_finish): Likewise. * locale/programs/ld-monetary.c (monetary_finish): Likewise. * locale/programs/ld-time.c (time_finish): Likewise. * locale/programs/locfile.c (write_locale_data): Likewise. * locale/programs/ld-ctype.c (ctype_class_to): Silently ignore unknown characters and empty ranges. * locale/programs/ld-collate.c (collate_order_elem): When processing an ellipsis properly form a linked list in the result table, fix typo when allocating ordering array. [PR libc/419] 1998-02-13 Andreas Schwab * elf/Makefile (ld-map): Define. (rtld-ldscript): Define. Change all `$(objpfx)rtld-ldscript' to `$(rtld-ldscript)'. ($(objpfx)ld.so): Combine the two versions of this rule. Depend on $(ld-map). (rtld-link): Combine the two versions of this definition. Fixed to make it work when no symbol versioning is used. 1998-02-16 Ulrich Drepper * Makeconfig (build-program-cmd): Use --library-path parameter to ld.so instead of environment variable. * sunrpc/Makefile (rpcgen-cmd): Don't use -$ parameter. * sunrpc/rpc_main.c: Remove support for -$$ option again. 1998-02-16 Andreas Jaeger * Make-dist: Respect with-cvs setting. * MakeTAGS (all-pot): Likewise. * sysdeps/sparc/sparc32/Makefile: Likewise. * sysdeps/mach/hurd/Makefile: Likewise. * stdlib/Makefile: Likewise. * posix/Makefile: Likewise. * intl/Makefile: Likewise. * po/Makefile (linguas): Likewise --- elf/Makefile | 30 +++++++++++------------------- elf/dl-load.c | 13 +++++++++---- elf/dl-support.c | 4 ++-- elf/link.h | 4 ++-- elf/rtld.c | 12 +++++++++++- 5 files changed, 35 insertions(+), 28 deletions(-) (limited to 'elf') diff --git a/elf/Makefile b/elf/Makefile index 093fc09369..739c230608 100644 --- a/elf/Makefile +++ b/elf/Makefile @@ -35,6 +35,7 @@ elide-routines.os = $(dl-routines) dl-support enbl-secure # ld.so uses those routines, plus some special stuff for being the program # interpreter and operating independent of libc. rtld-routines := rtld $(dl-routines) dl-sysdep dl-minimal +ld-map = $(libc-map) distribute = $(rtld-routines:=.c) dynamic-link.h do-rel.h dl-machine.h \ dl-hash.h soinit.c sofini.c ldd.sh.in ldd.bash.in eval.c \ genrtldtbl.awk atomicity.h dl-procinfo.h @@ -88,22 +89,22 @@ $(objpfx)librtld.os: $(objpfx)dl-allobjs.os $(common-objpfx)libc_pic.a # Do we need a linker script? rtld-ldscript-in := $(firstword $(wildcard $(+sysdep_dirs:%=%/rtld-ldscript.in))) -ifeq ($(versioning),yes) -RTLD-VERSIONS = -Wl,--version-script=$(libc-map) -endif - ifneq (,$(rtld-ldscript-in)) -LDFLAGS-rtld = -T $(objpfx)rtld-ldscript +rtld-ldscript = $(objpfx)rtld-ldscript +generated += rtld-ldscript + +LDFLAGS-rtld = -T $(rtld-ldscript) +before-compile += $(rtld-ldscript) -before-compile += $(objpfx)rtld-ldscript rtld-parms = $(wildcard $(+sysdep_dirs:%=%/rtld-parms)) include $(rtld-parms) -generated += rtld-ldscript -$(objpfx)rtld-ldscript: $(rtld-ldscript-in) $(rtld-parms) + +$(rtld-ldscript): $(rtld-ldscript-in) $(rtld-parms) sed -e 's#@@rtld-oformat@@#$(rtld-oformat)#' \ -e 's#@@rtld-arch@@#$(rtld-arch)#' \ -e 's#@@rtld-entry@@#$(rtld-entry)#' \ -e 's#@@rtld-base@@#$(rtld-base)#' $< >$@ +endif $(objpfx)ld.so: $(objpfx)librtld.os $(objpfx)rtld-ldscript $(rtld-link) -Wl,-soname=$(rtld-installed-name) @@ -111,18 +112,9 @@ $(objpfx)ld.so: $(objpfx)librtld.os $(objpfx)rtld-ldscript define rtld-link $(LINK.o) -nostdlib -nostartfiles -shared -o $@ \ -Wl,-rpath=$(default-rpath) $(LDFLAGS-rtld) \ - $(filter-out $(objpfx)rtld-ldscript,$^) \ - $(RTLD-VERSIONS) + $(filter-out $(rtld-ldscript) $($(@F:.so=)-map),$^) \ + $(load-map-file:%=-Wl,--version-script=%) endef -else -$(objpfx)ld.so: $(objpfx)librtld.os - $(rtld-link) -Wl,-soname=$(rtld-installed-name) - -define rtld-link -$(LINK.o) -nostdlib -nostartfiles -shared -o $@ \ - -Wl,-rpath=$(default-rpath) $^ $(RTLD-VERSIONS) -endef -endif # The dl code in the static libc needs a default library path.
