From 8a0746ae74914cbdf02fc609e15d267692695792 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sun, 1 Apr 2001 05:04:31 +0000 Subject: * sysdeps/mach/hurd/Makefile ($(link-rpcuserlibs)): Don't append options after $(build-module), which is no longer a single command. (LDFLAGS-link-rpcuserlibs): New variable to hold those options. (LDFLAGS-libmachuser-link.so, LDFLAGS-libhurduser-link.so): New variables using it. Reported by Mark Kettenis . 2001-03-11 Roland McGrath * elf/rtld.c (dl_main): Add cast to quiet warning. * elf/dl-load.c (_dl_map_object_from_fd): Likewise. * iconv/gconv_conf.c (__gconv_get_path): Likewise. (__gconv_read_conf): Likewise. * iconv/gconv_db.c (gen_steps): Likewise. (__gconv_find_transform): Likewise. * locale/programs/charmap-dir.c (fopen_uncompressed): Likewise. (fopen_uncompressed): Use const in second argument's type. 2001-03-11 Roland McGrath * sysdeps/mach/hurd/dl-sysdep.c (__writev): New function. * mach/mach_error.h: Fix ancient #endif syntax. * hurd/hurdmalloc.c: Likewise. * sysdeps/generic/atomicity.h (exchange_and_add, atomic_add, compare_and_swap): Add volatile qualifier to first arg, to bring these prototypes in line with all the other implementations. Add a #warning to remind the builder that these are not atomic. 2001-03-04 Roland McGrath * hurd/vpprintf.c (vpprintf) [USE_IN_LIBIO]: Use innermore first member of TEMP_F so its type is _IO_FILE * as expected. * hurd/fopenport.c (seekio): Conditionalize type of POS argument on [USE_IN_LIBIO]. Check the value for overflow, since for libio it might exceed off_t's range. 2001-02-25 Roland McGrath * sysdeps/mach/hurd/sysd-stdio.c (__stdio_reopen): Use prototype. * sysdeps/unix/bsd/getpt.c (__posix_openpt): Likewise. * sysdeps/mach/hurd/i386/intr-msg.h (SYSCALL_EXAMINE): Make this a macro instead of an inline function, (MSG_EXAMINE): Likewise. * hurd/hurd/ioctl.h (_HURD_HANDLE_IOCTLS_1): Remove extraneous ##. * hurd/get-host.c: Include for decls of built-ins. * hurd/hurdchdir.c: Likewise. * sysdeps/mach/hurd/i386/sigreturn.c: Likweise. * sysdeps/mach/hurd/opendir.c: Likewise. * mach/mach_init.c: Include for _exit decl. * mach/errsystems.awk: Give output file a trailing newline. * mach/Machrules (MIG): Prepend CC='${CC}' to the mig command, so that the script will use our compiler for the cpp stage. With --enable-all-warnings we get a whole bunch of warnings, and these are just a few fixes; there are more needed to silence it. * mach/mach/mig_support.h (__mig_strncpy, mig_strncpy): Add extern decls before extern inline defns to quiet gcc warning. * hurd/hurd/threadvar.h (__hurd_threadvar_location_from_sp): Likewise. * sysdeps/mach/i386/machine-sp.h (__thread_stack_pointer): Likewise. --- sysdeps/mach/hurd/Makefile | 9 +++- sysdeps/mach/hurd/dl-sysdep.c | 34 +++++++++++++- sysdeps/mach/hurd/i386/intr-msg.h | 90 ++++++++++++++++++-------------------- sysdeps/mach/hurd/i386/sigreturn.c | 3 +- sysdeps/mach/hurd/opendir.c | 3 +- sysdeps/mach/hurd/sysd-stdio.c | 11 +++-- sysdeps/mach/i386/machine-sp.h | 3 +- 7 files changed, 94 insertions(+), 59 deletions(-) (limited to 'sysdeps/mach') diff --git a/sysdeps/mach/hurd/Makefile b/sysdeps/mach/hurd/Makefile index 05bf1d222d..007016dabc 100644 --- a/sysdeps/mach/hurd/Makefile +++ b/sysdeps/mach/hurd/Makefile @@ -1,4 +1,4 @@ -# Copyright (C) 1993,94,95,96,97,98,99,2000 Free Software Foundation, Inc. +# Copyright (C) 1993,94,95,96,97,98,99,2000,01 Free Software Foundation, Inc. # This file is part of the GNU C Library. # The GNU C Library is free software; you can redistribute it and/or @@ -149,7 +149,12 @@ lib-noranlib: $(common-objpfx)hurd/libhurduser-link.so endif $(link-rpcuserlibs): %-link.so: %_pic.a - $(build-module) -nostdlib -Wl,-soname=$(*F).so$($(*F).so-version) +# The $(build-module) variable now contains a sequence of several commands, +# so we can't tweak the ld command just by adding text to this command line. + $(build-module) +LDFLAGS-link-rpcuserlibs = -nostdlib -Wl,-soname=$(*F).so$($(*F).so-version) +LDFLAGS-libmachuser-link.so = $(LDFLAGS-link-rpcuserlibs) +LDFLAGS-libhurduser-link.so = $(LDFLAGS-link-rpcuserlibs) # And get them into the libc.so ldscript. $(inst_libdir)/libc.so: $(rpcuserlibs) diff --git a/sysdeps/mach/hurd/dl-sysdep.c b/sysdeps/mach/hurd/dl-sysdep.c index 3e0531b10b..25ae5bbc68 100644 --- a/sysdeps/mach/hurd/dl-sysdep.c +++ b/sysdeps/mach/hurd/dl-sysdep.c @@ -1,5 +1,5 @@ /* Operating system support for run-time dynamic linker.
