From c776b3d717593ee3fdd2120f80217f0abe0dec74 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 10 Dec 2003 23:02:33 +0000 Subject: Update. 2003-12-02 David Mosberger * sysdeps/ia64/elf/initfini.c: Add unwind info. * sysdeps/ia64/dl-machine.h (elf_machine_matches_host): Mark with attribute "unused". (elf_machine_dynamic): Mark with attributes "unused" and "const". (elf_machine_runtime_setup): Likewise. * sysdeps/generic/dl-fptr.c (make_fptr_table): Mark with attribute "always_inline". * sysdeps/ia64/dl-machine.h (__ia64_init_bootstrap_fdesc_table): Likewise. * configure.in: Check whether compiler has libunwind support. * config.make.in (have-cc-with-libunwind): New variable. * config.h.in (HAVE_CC_WITH_LIBUNWIND): New macro. * Makeconfig (gnulib): If have-cc-withh-libunwind is "yes", also mention -lunwind. 003-11-12 David Mosberger * sysdeps/unix/sysv/linux/ia64/sysdep.h: Define DO_CALL_VIA_BREAK. Redefine DO_CALL to use vdso if supported, otherwise DO_CALL_VIA_BREAK. Likewise for DO_INLINE_SYSCALL. Make INTERNAL_SYSCALL use DO_INLINE_SYSCALL. * sysdeps/unix/sysv/linux/ia64/vfork.S: Use DO_CALL_VIA_BREAK() instead of DO_CALL(). * sysdeps/unix/sysv/linux/ia64/clone2.S: Use break directly instead of DO_CALL(). * sysdeps/unix/sysv/linux/ia64/brk.S (__curbrk): Restructure it to take advantage of DO_CALL() macro. * sysdeps/unix/sysv/linux/ia64/setcontext.S: Likewise. * sysdeps/unix/sysv/linux/ia64/getcontext.S: Likewise. * elf/rtld.c (dl_main): Restrict dl_sysinfo_dso check to first program header. On ia64, the check failed previously because there are two program headers. * sysdeps/generic/s_nexttowardf.c: Likewise. * math/bug-nexttoward.c: New file. --- nptl/sysdeps/ia64/tls.h | 15 ++++++++++++--- 1 file changed, 12 insertions(+), 3 deletions(-) (limited to 'nptl/sysdeps/ia64/tls.h') diff --git a/nptl/sysdeps/ia64/tls.h b/nptl/sysdeps/ia64/tls.h index b6b20c0f50..262944d89f 100644 --- a/nptl/sysdeps/ia64/tls.h +++ b/nptl/sysdeps/ia64/tls.h @@ -42,6 +42,8 @@ typedef struct void *private; } tcbhead_t; +register struct pthread *__thread_self __asm__("r13"); + # define TLS_MULTIPLE_THREADS_IN_TCB 1 #else /* __ASSEMBLER__ */ @@ -64,8 +66,6 @@ typedef struct /* Get system call information. */ # include -register struct pthread *__thread_self __asm__("r13"); - /* This is the size of the initial TCB. */ # define TLS_INIT_TCB_SIZE sizeof (tcbhead_t) @@ -100,11 +100,20 @@ register struct pthread *__thread_self __asm__("r13"); # define GET_DTV(descr) \ (((tcbhead_t *) (descr))->dtv) +#define THREAD_SELF_SYSINFO (((tcbhead_t *) __thread_self)->private) +#define THREAD_SYSINFO(pd) (((tcbhead_t *) ((pd) + 1))->private) + +#if defined NEED_DL_SYSINFO +# define INIT_SYSINFO THREAD_SELF_SYSINFO = (void *) GL(dl_sysinfo) +#else +# define INIT_SYSINFO NULL +#endif + /* Code to initially initialize the thread pointer.
