From 4dbb64174c5cc00dc2aa40784b57889f8e0b6c5e Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 7 Jul 2001 22:59:32 +0000 Subject: [PATCH] Update. 2001-07-06 Jakub Jelinek * sysdeps/unix/sysv/linux/i386/sigaction.c (RESTORE2): Put asm explicitly into .text section. 2001-04-16 Jes Sorensen * sysdeps/unix/sysv/linux/ia64/bits/sigcontext.h (struct sigcontext): Add 16 longwords reserved for future use to match changes in the kernel. 2001-07-03 Jes Sorensen * sysdeps/ia64/strncpy.S: Call strnlen() when determining the string length rather than strlen(). Solves the performance problem of doing strlen on a 5MB string when strncpy was called with a length argument of 5 bytes. 2001-07-02 Jakub Jelinek * sysdeps/sparc/sparc32/dl-machine.h (elf_machine_rela): Handle R_SPARC_UA16 and R_SPARC_UA32. * sysdeps/sparc/sparc64/dl-machine.h (elf_machine_rela): Likewise. 2001-07-01 Stephen L Moshier * sysdeps/ieee754/ldbl-96/e_acoshl.c (__ieee754_acoshl): acosh(x) = ln(2x) if x > 2^30. * sysdeps/ieee754/ldbl-128/e_acoshl.c (__ieee754_acoshl): acosh(x) = ln(2x) if x > 2^54. * sysdeps/hppa/dl-machine.h (elf_machine_rela): Handle relocs --- ChangeLog | 33 ++++++++++++++++++- sysdeps/ia64/strncpy.S | 9 ++--- sysdeps/ieee754/ldbl-128/e_acoshl.c | 2 +- sysdeps/sparc/sparc32/dl-machine.h | 10 ++++++ sysdeps/sparc/sparc64/dl-machine.h | 10 ++++++ sysdeps/unix/sysv/linux/i386/sigaction.c | 6 ++-- .../unix/sysv/linux/ia64/bits/sigcontext.h | 1 + 7 files changed, 63 insertions(+), 8 deletions(-) diff --git a/ChangeLog b/ChangeLog index 75089015ed..4c1161beab 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,34 @@ +2001-07-06 Jakub Jelinek + + * sysdeps/unix/sysv/linux/i386/sigaction.c (RESTORE2): Put asm + explicitly into .text section. + +2001-04-16 Jes Sorensen + + * sysdeps/unix/sysv/linux/ia64/bits/sigcontext.h (struct sigcontext): + Add 16 longwords reserved for future use to match changes in the + kernel. + +2001-07-03 Jes Sorensen + + * sysdeps/ia64/strncpy.S: Call strnlen() when determining the + string length rather than strlen().
