Ulrich Drepper e1f601e878 Update.
1999-02-03  Jakub Jelinek  <jj@ultra.linux.cz>

	* sysdeps/generic/segfault.c: Add ADVANCE_STACK_FRAME
	macro, so that architectures which need to add some special
	offset to stack pointer can share this file.

	* sysdeps/unix/sysv/linux/sparc/sparc32/sigcontextinfo.h: New file.
	* sysdeps/unix/sysv/linux/sparc/sparc32/register-dump.h: New file.
	* sysdeps/unix/sysv/linux/sparc/sparc64/sigcontextinfo.h: New file.
	* sysdeps/unix/sysv/linux/sparc/sparc64/register-dump.h: New file.

	* sysdeps/unix/sysv/linux/sparc/sparc32/bits/mman.h: Remove.
	* sysdeps/unix/sysv/linux/sparc/sparc64/bits/mman.h: Remove.
	* sysdeps/unix/sysv/linux/sparc/bits/mman.h: New file - common
	between sparc32 and sparc64.

	* sysdeps/unix/sysv/linux/sparc/sparc32/vfork.S: Remove.
	* sysdeps/unix/sysv/linux/sparc/sparc64/vfork.S: Remove.
	* sysdeps/unix/sysv/linux/sparc/vfork.S: New file - common
