* gcore.c (gcore_command): Use gcore_default_target instead of NULL.
	(default_gcore_mach): Just return 0, work around a problem in bfd.
	(default_gcore_target): OK to return NULL if exec_bfd is null.
	(make_mem_sec): Use a cast, avoid a warning.

	* procfs.c (find_memory_regions_callback): Use a cast instead of
	calling host_pointer_to_address (which complains if
	sizeof (host pointer) != sizeof (target pointer)).
	(procfs_make_note_section): Avoid overflow in psargs string.

* procfs.c (procfs_make_note_section): Make the default
	implementation return an error.

2002-02-13  Rodney Brown  <rbrown64@csc.com.au>

	* procfs.c (procfs_make_note_section): Provide a default definition
	(for alpha-dec-osf4.0f). Fix typos.

2002-02-11  Michael Snyder  <msnyder@redhat.com>

	* procfs.c: Include elf-bfd.h (for elfcore_write functions).
	(gcore section): Ifdef for Solaris and Unixware only.
	(procfs_do_thread_registers): Unixware needs one lwpstatus
	per thread (not one prstatus or pstatus).
	(procfs_make_note_section): Iterate only over kernel threads (lwps),
	not over all gdb threads.  For unixware, call elfcore_write_pstatus
	once before iterating over threads.

Michael Snyder 6c1a54b22b 2000-05-05 Michael Snyder <msnyder@seadog.cygnus.com>
* procfs.c (many functions): change int cmd; to long cmd;
        Solaris /proc API calls this parameter a long, and requires it
        for 64-bit hosts (where sizeof(long) != sizeof(int)).  UnixWare
        calls it an int, but on existing UnixWare hosts, int and long
        are the same size.  So long it must be.  If a future UnixWare
        version has problems with this, we'll have to use autoconf.
        * proc-api.c (write_with_trace): use long instead of int.

	fill_fpregset, supply_fpregset): declare.
	(procfs_wait): Sysargs is a long, change printf format to match.
	(test-mapping, mapping_test, test_mapping_cmd) Remove (test only).
