From 0a45b76c6238f4685c07ba5c5db371ae9b95d661 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 25 Mar 2001 05:15:51 +0000 Subject: Update. 2001-03-23 Jes Sorensen * sysdeps/unix/sysv/linux/ia64/sysdep.h (ENTRY): Moved to ... * sysdeps/ia64/sysdep.h: ...here. * sysdeps/ia64/sysdep.h (LOCAL_ENTRY): Define. * sysdeps/ia64/sysdep.h (LOCAL_LEAF): Define. * sysdeps/ia64/_mcount.S (_mcount_ret_helper): Use LOCAL_LEAF() to declare instead of LEAF(). Suggestion from David Mosberger. 2001-03-21 David Mosberger * sysdeps/unix/sysv/linux/ia64/sysdep.h (CALL_MCOUNT): Add unwind directives. (PSEUDO): Drop .psr and .lsb directives. * sysdeps/unix/sysv/linux/ia64/setjmp.S: Ditto. Add unwind directives. * sysdeps/unix/sysv/linux/ia64/sysdep.S: Ditto. * sysdeps/ia64/elf/start.S: Misc cleanup: remove .psr and .lsb directives etc. * sysdeps/unix/sysv/linux/ia64/brk.S: Ditto. * sysdeps/unix/sysv/linux/ia64/__longjmp.S: Ditto. * sysdeps/ia64/_mcount.S: Remove .psr and .lsb directives (no longer needed). Add unwind directives. * sysdeps/ia64/sysdep.h: Define ASM_UNW_PRLG_RP, ASM_UNW_PRLG_PFS, ASM_UNW_PRLG_PSP, ASM_UNW_PRLG_PR, and ASM_UNW_PRLG_GRSAVE. 2001-03-21 Paul Eggert * posix/regex.h (RE_INVALID_INTERVAL_ORD): New macro. (RE_SYNTAX_POSIX_EGREP): Use it. * posix/regex.c (regex_compile): Implement it. 2001-03-21 Paul Eggert * posix/regex.c (GET_UNSIGNED_NUMBER): Check for overflow. Rewrite to avoid duplicate code. 2001-03-21 H.J. Lu * elf/Makefile (tests): Don't depend on $(objpfx)tst-pathopt.out for cross-compiling. ($(objpfx)tst-pathopt.out): Undo the last change. --- sysdeps/unix/sysv/linux/ia64/__longjmp.S | 16 +++--------- sysdeps/unix/sysv/linux/ia64/brk.S | 28 ++++++++------------ sysdeps/unix/sysv/linux/ia64/setjmp.S | 44 +++++++++++++------------------- sysdeps/unix/sysv/linux/ia64/sysdep.S | 22 +++++----------- sysdeps/unix/sysv/linux/ia64/sysdep.h | 35 ++++++++++--------------- 5 files changed, 53 insertions(+), 92 deletions(-) (limited to 'sysdeps/unix') diff --git a/sysdeps/unix/sysv/linux/ia64/__longjmp.S b/sysdeps/unix/sysv/linux/ia64/__longjmp.S index 967cab593d..956d3c7870 100644 --- a/sysdeps/unix/sysv/linux/ia64/__longjmp.S +++ b/sysdeps/unix/sysv/linux/ia64/__longjmp.S @@ -1,4 +1,4 @@ -/* Copyright (C) 1999, 2000 Free Software Foundation, Inc. +/* Copyright (C) 1999, 2000, 2001 Free Software Foundation, Inc.
