From 57ba7bb47152ed3e50805db2bca137cb866a9a71 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 5 Sep 1996 02:49:18 +0000 Subject: update from main archive 960904 Thu Sep 5 03:20:42 1996 Ulrich Drepper Change configuration and Makefiles to allow add-ons to have a sysdeps/ directory hierachy. * configure.in: Test for sysdeps/ directory in add-ons. Before all test and searches in these hierachies, too. * Makeconfig (full-config-subdirs): Define based on $(config-sysdirs). Extend with $(..) if not absolute path. Use $(full-config-subdirs) where $(config-sysdirs) was used. * Makefile ($(objpfx)sysd-dirs): Use config-sysdirs. * MakeTAGS: Use $(full-config-subdirs). * Makerules: Change comment to libc.so link script. (sysdirs): Define based on $(full-config-subdirs). (sysd-Makefile): Define using config-sysdirs. (sysd-rules): Likewise. * sysdeps/unix/Makefile (sysd-syscalls): Define based on +sysdep-dirs. * sysdeps/unix/make-syscalls.sh: Remove basedir argument. Wed Sep 4 01:32:21 1996 Andreas Schwab * sysdeps/m68k/fpu/k_cos.c: Rewritten for better accuracy. * sysdeps/m68k/fpu/k_sin.c: Likewise. * sysdeps/m68k/fpu/k_tan.c: Likewise. Thu Sep 5 01:06:09 1996 Richard Henderson * malloc/free.c (free): Protect by using __libc_malloc_lock. * malloc/malloc-find.c (malloc_find_object_address): Likewise. * malloc/malloc-size.c (malloc_usable_size): Likewise. * malloc/malloc-walk.c (malloc_walk): Likewise. * malloc/memalign.c (memalign): Likewise. * malloc/realloc.c (realloc): Likewise. * malloc/malloc.c: Define __libc_malloc_lock. (_malloc_internal): Don't use `malloc'. Instead look for `__malloc_hook' or call `_malloc_internal'. (malloc): Protect by using `__libc_malloc_lock'. * malloc/malloc.h: Declare `__libc_malloc_lock'. Mon Sep 2 22:42:59 1996 Richard Henderson * sysdeps/alpha/elf/start.S: Use weak_alias for __start instead of the hard definition. * sysdeps/alpha/dl-machine.h (RTLD_START): Add type info for _start and _dl_start_user. * sysdeps/unix/sysv/linux/alpha/init-first.h (SYSDEP_CALL_INIT): Make _dl_starting_up weak. Add type info for NAME. Mon Sep 2 22:15:14 1996 Richard Henderson * Makefile (all): Add extra_solibs pass. (+subdir_targets): Same. * Rules (extra_solibs): New phony empty target for subdirs without extra libs. * extra-lib.mk: Build lib*.so* in extra_solibs not lib-noranlib. * manual/Makefile: Add dummy extra_solibs target. Sun Sep 1 15:41:22 1996 Richard Henderson * Makeconfig (+link): Add $(link-extra-libs). (link-extra-libs): New variable which expands to the full paths of the other libraries needed by a program, as controled by LDLIBS-$(@F). * db/Makefile: Use LDLIBS-makedb to link libdb not a dependency, as the later attempts to install the library before linking it. * sysdeps/unix/alpha/sysdep.S: Align errno. * sysdeps/unix/sysv/linux/alpha/ioperm.c (struct platform): Add hae_shift entry. (io): Move bus_memory_base and sparse_bus_memory_base into struct. (_hae_shift): New function. * sysdeps/unix/sysv/linux/alpha/sys/io.h: New file. Prototypes for the bus query functions. Sat Aug 31 18:14:54 1996 Richard Henderson * elf/dl-close.c (_dl_close): In static executables, map->l_prev can be NULL when unloading a library. * elf/dl-open.c (_dl_open): Pass __environ instead of __libc_envp to the library .init function. * sysdeps/alpha/dl-machine.h (elf_machine_rela): Since we omitted part of the COPY reloc processing earlier, omit the rest now -- we'll get into less trouble later when some fool does use a COPY. * sysdeps/unix/sysv/linux/init-first.c (init): Accept argc et al as parameters. Move all argc and __libc_multiple_libcs calculation out to init-first.h. Use __environ not __libc_envp. * sysdeps/unix/sysv/linux/alpha/init-first.h: Rewrite. * sysdeps/unix/sysv/linux/i386/init-first.h: Rewrite. Thu Aug 29 20:26:40 1996 Andreas Schwab * sysdeps/posix/profil.c (profil): Don't clobber saved timer and signal settings when profiling was already turned on. * csu/gmon-start.c (__gmon_start__) [HAVE_INITFINI]: Protect from being called twice. Wed Sep 4 01:31:50 1996 Ulrich Drepper * sysdeps/unix/sysv/linux/i386/mmap.S: Test for 0 < return value < -4096 and not < 0 to decide about failure. Reported by Andreas Jaeger. Tue Sep 3 19:04:05 1996 Ulrich Drepper * stdio-common/vfscanf.c (__vfscanf): Don't count EOF char in %c format. Sat Aug 31 18:10:51 1996 Ulrich Drepper * wcsmbs/wchar.h: Define prototypes for wcstoq and wcstouq only #ifdef __USE_GNU. Sat Aug 31 12:34:29 1996 Ulrich Drepper * version.c: Add missing newline character in banner. * sysdeps/unix/sysv/linux/alpha/Dist: Correct typo. * sysdeps/unix/sysv/linux/i386/Dist: Likewise. Sat Aug 31 03:07:39 1996 Ulrich Drepper * intl/l10nflist.c (_nl_normalize_codeset): We convert to lower case, so don't prepend uppercase `ISO' for only numeric arg. --- sysdeps/unix/sysv/linux/alpha/Dist | 3 +- sysdeps/unix/sysv/linux/alpha/Makefile | 2 +- sysdeps/unix/sysv/linux/alpha/init-first.h | 39 ++++++++++++++------ sysdeps/unix/sysv/linux/alpha/ioperm.c | 47 +++++++++++++++--------- sysdeps/unix/sysv/linux/alpha/sys/io.h | 59 ++++++++++++++++++++++++++++++ 5 files changed, 119 insertions(+), 31 deletions(-) create mode 100644 sysdeps/unix/sysv/linux/alpha/sys/io.h (limited to 'sysdeps/unix/sysv/linux/alpha') diff --git a/sysdeps/unix/sysv/linux/alpha/Dist b/sysdeps/unix/sysv/linux/alpha/Dist index 79ac03ff90..d898d041a2 100644 --- a/sysdeps/unix/sysv/linux/alpha/Dist +++ b/sysdeps/unix/sysv/linux/alpha/Dist @@ -1,5 +1,6 @@ -alpha/ptrace.halpha/regdef.h +alpha/ptrace.h alpha/regdef.h ieee_get_fp_control.S ieee_set_fp_control.S ioperm.c init-first.h clone.S +sys/io.h diff --git a/sysdeps/unix/sysv/linux/alpha/Makefile b/sysdeps/unix/sysv/linux/alpha/Makefile index 3908b5703c..fa433e9d8b 100644 --- a/sysdeps/unix/sysv/linux/alpha/Makefile +++ b/sysdeps/unix/sysv/linux/alpha/Makefile @@ -1,5 +1,5 @@ ifeq ($(subdir), misc) -sysdep_headers += alpha/ptrace.h alpha/regdef.h +sysdep_headers += alpha/ptrace.h alpha/regdef.h sys/io.h sysdep_routines += ieee_get_fp_control ieee_set_fp_control \ sethae ioperm osf_sigprocmask fstatfs statfs llseek diff --git a/sysdeps/unix/sysv/linux/alpha/init-first.h b/sysdeps/unix/sysv/linux/alpha/init-first.h index c27c589a28..ffbcaf1521 100644 --- a/sysdeps/unix/sysv/linux/alpha/init-first.h +++ b/sysdeps/unix/sysv/linux/alpha/init-first.h @@ -1,12 +1,29 @@ -/* This fragment is invoked in the stack context of program start. - Its job is to set up a pointer to argc as an argument, pass - control to `INIT', and, if necessary, clean up after the call - to leave the stack in the same condition it was found in. */ +/* The job of this fragment it to find argc and friends for INIT. + This is done in one of two ways: either in the stack context + of program start, or having dlopen pass them in. */ -#define SYSDEP_CALL_INIT(NAME, INIT) \ - asm(".globl " #NAME "\n" \ - #NAME ":\n\t" \ - "ldgp $29, 0($27)\n\t" \ - ".prologue 1\n\t" \ - "mov $30, $16\n\t" \ - "br $31, " #INIT "..ng"); +#define SYSDEP_CALL_INIT(NAME, INIT) \ + asm(".weak _dl_starting_up\n\t" \ + ".globl " #NAME "\n\t" \ + ".ent " #NAME "\n" \ + #NAME ":\n\t" \ + "ldgp $29, 0($27)\n\t" \ + ".prologue 1\n\t" \ + ".set at\n\t" \ + /* Are we a dynamic libc being loaded into a static program? */ \ + "lda $0, _dl_starting_up\n\t" \ + "beq $0, 1f\n\t" \ + "ldl $0, 0($0)\n" \ + "cmpeq $31, $0, $0\n" \ + "1:\t" \ + "stl $0, __libc_multiple_libcs\n\t" \ + /* If so, argc et al are in a0-a2 already.
