From b5ec56172d65dd37437846363e742249126d5975 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 13 Mar 2003 04:41:39 +0000 Subject: Update. 2003-03-13 Jakub Jelinek * sysdeps/unix/sysv/linux/ia64/sysdep.h (BREAK_INSN_1, BREAK_INSN, ASM_OUTARGS_0, ASM_OUTARGS_1, ASM_OUTARGS_2, ASM_OUTARGS_3, ASM_OUTARGS_4, ASM_OUTARGS_5, ASM_OUTARGS_6): Define. (INTERNAL_SYSCALL, INLINE_SYSCALL): Use it. Make syscall arguments clobbered by the syscall. (ASM_ARGS_1, ASM_ARGS_2, ASM_ARGS_3, ASM_ARGS_4, ASM_ARGS_5, ASM_ARGS_6): Change constraints from r to index of corresponding output register. * sysdeps/unix/sysv/linux/ia64/clone2.S (__clone2): Swap ptid and ctid to match kernel. * sysdeps/unix/sysv/linux/ia64/system.c (FORK): Likewise. * sysdeps/powerpc/powerpc64/elf/configure.in: Remove * sysdeps/powerpc/powerpc64/elf/configure: Regenerated. --- sysdeps/unix/sysv/linux/ia64/clone2.S | 4 ++-- sysdeps/unix/sysv/linux/ia64/sysdep.h | 35 +++++++++++++++++++++++------------ sysdeps/unix/sysv/linux/ia64/system.c | 2 +- 3 files changed, 26 insertions(+), 15 deletions(-) (limited to 'sysdeps') diff --git a/sysdeps/unix/sysv/linux/ia64/clone2.S b/sysdeps/unix/sysv/linux/ia64/clone2.S index bdd37ae..17620ff 100644 --- a/sysdeps/unix/sysv/linux/ia64/clone2.S +++ b/sysdeps/unix/sysv/linux/ia64/clone2.S @@ -42,8 +42,8 @@ ENTRY(__clone2) mov out0=in3 /* Flags are first syscall argument. */ mov out1=in1 /* Stack address. */ mov out2=in2 /* Stack size. */ - mov out3=in7 /* Child TID Pointer */ - mov out4=in5 /* Parent TID Pointer */ + mov out3=in5 /* Parent TID Pointer */ + mov out4=in7 /* Child TID Pointer */ mov out5=in6 /* TLS pointer */ DO_CALL (SYS_ify (clone2)) cmp.eq p6,p0=-1,r10 diff --git a/sysdeps/unix/sysv/linux/ia64/sysdep.h b/sysdeps/unix/sysv/linux/ia64/sysdep.h index 4522fb9..556e266 100644 --- a/sysdeps/unix/sysv/linux/ia64/sysdep.h +++ b/sysdeps/unix/sysv/linux/ia64/sysdep.h @@ -105,6 +105,9 @@ #else /* not __ASSEMBLER__ */ +#define BREAK_INSN_1(num) "break " #num ";;\n\t" +#define BREAK_INSN(num) BREAK_INSN_1(num) + /* On IA-64 we have stacked registers for passing arguments.
