From 4d6acc61fa6892b40eaf94de4ff506ff83e37490 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 13 Jun 1996 04:06:45 +0000 Subject: Thu Jun 13 00:02:25 1996 Roland McGrath * elf/dl-lookup.c (_dl_lookup_symbol): If no value and *REF is null, consider it a strong reference and give the error. Wed Jun 12 15:52:46 1996 Roland McGrath * elf/dl-open.c (_dl_open): Correctly terminate relocating loop after relocating NEW when it's the only new object. * elf/dl-init.c (_dl_init_next): When out of initializers, set _r_debug.r_state to RT_CONSISTENT and call _dl_debug_state just before return. * elf/rtld.c (dl_main): Move _dl_debug_initialize call after relocation. Call it unconditionally and only fill in DT_DEBUG if it's present. Then call _dl_debug_state with r_state RT_ADD before running initializers. * elf/dl-open.c (_dl_open): Call _dl_debug_initialize and then call _dl_debug_state with r_state RT_ADD before running initializers * elf/dl-close.c (_dl_close): Call _dl_debug_state with r_state RT_DELETE before running finalizers and with RT_CONSISTENT just before return. * elf/Makefile (dl-routines): Add dl-debug. * elf/dl-debug.c: New file. * elf/rtld.c (_dl_r_debug): Rename to _r_debug and move to dl-debug.c. (_dl_r_debug_state): Rename to _dl_debug_state and likewise move. (dl_main): Use _dl_debug_initialize. * elf/link.h: Fix name to _dl_debug_state in decl. (_dl_debug_initialize): Declare new function from dl-debug.c. (_r_debug): Declare it. * Makerules (distinfo-vars): Add install-{lib,data,bin,sbin,others}. In distinfo set $(subdir)-VAR and then set VAR to $($(subdir)-VAR). * Makeconfig (rpath-link): New variable; add $(elfobjdir). (default-rpath): Use it. (built-program-cmd): Use it in LD_LIBRARY_PATH. * Makeconfig (sysdep-configures): Prepend $(sysdep_dir) to names tried. * sysdeps/unix/Dist: Add make-syscalls.sh. * misc/Makefile (headers): Add sys/swap.h. * posix/unistd.h: Remove decls for swapon, swapoff. * sysdeps/generic/sys/swap.h: New file. * sysdeps/unix/sysv/linux/sys/swap.h: New file. * sysdeps/unix/sysv/linux/gnu/types.h: Remove temporary hack #define of __kernel_fsid_t. It is correctly defines in now. --- sysdeps/generic/sys/swap.h | 33 +++++++++++++++++++++++++++++++++ sysdeps/unix/Dist | 1 + sysdeps/unix/sysv/linux/gnu/types.h | 1 - sysdeps/unix/sysv/linux/sys/swap.h | 37 +++++++++++++++++++++++++++++++++++++ 4 files changed, 71 insertions(+), 1 deletion(-) create mode 100644 sysdeps/generic/sys/swap.h create mode 100644 sysdeps/unix/sysv/linux/sys/swap.h (limited to 'sysdeps') diff --git a/sysdeps/generic/sys/swap.h b/sysdeps/generic/sys/swap.h new file mode 100644 index 0000000..17003a8 --- /dev/null +++ b/sysdeps/generic/sys/swap.h @@ -0,0 +1,33 @@ +/* Calls to enable and disable swapping on specified locations.
