2001-03-23 Jes Sorensen <jes@linuxcare.com> * 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 <davidm@hpl.hp.com> * 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 <eggert@twinsun.com> * 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 <eggert@twinsun.com> * posix/regex.c (GET_UNSIGNED_NUMBER): Check for overflow. Rewrite to avoid duplicate code. 2001-03-21 H.J. Lu <hjl@gnu.org> * elf/Makefile (tests): Don't depend on $(objpfx)tst-pathopt.out for cross-compiling. ($(objpfx)tst-pathopt.out): Undo the last change.
