2000-01-24 Kevin Buettner <kevinb@redhat.com>
* utils.c (get_field, put_field): Fix buffer underruns and
overruns. Also, handle case where total_len is not evenly
divisible by 8.
(getfield): Make sure zeroing of unwanted bits occurs even
when bit field to extract does not straddle two or more
bytes.
2000-01-23 Christopher Faylor <cgf@cygnus.com>
* defs.h: Add gdb_thread_select declaration.
2000-01-23 Kevin Buettner <kevinb@redhat.com>
* linux-thread.c (_initialize_linuxthreads): Make sure that
linuxthreads_block_mask does not block SIGCHLD.
2000-01-20 Fernando Nasser <fnasser@totem.to.cygnus.com>
* rdi-share/devsw.c (openLogFile): On cygwin, set the log mode to
text so that new lines work properly.
2000-01-18 Elena Zannoni <ezannoni@kwikemart.cygnus.com>
* proc-utils.h: New file. Export functions from proc-*.c.
* proc_api.c: Rename to:
* proc-api.c: New file. Add include of proc-utils.h.
* proc_events.c: Rename to:
* proc-events.c: New file.
* proc_flags.c: Rename to:
* proc-flags.c: New file.
* proc_why.c: Rename to:
* proc-why.c: New file. Add include of proc-utils.h.
* procfs.c: Add includes of gdbthread.h, sys/wait.h, signal.h,
ctype.h, proc-utils.h.
(find_procinfo_or_die): Add braces to avoid ambiguous else clause.
(open_procinfo_files): Conditionalize local variable tmp, to avoid
compiler warnings.
(proc_iterate_over_mappings): Conditionalize local vars mapfd and
pathname.
(procfs_wait): Adjust format in some printf_filetered calls to
avoid compiler warnings.
(make_signal_thread_runnable): Ifdef 0. The calls to this function
are also ifdef'd 0 .
(procfs_resume): Add parentheses around '&&' operation.
(procfs_set_exec_trap): Remove unused variable.
(info_proc_cmd): Add braces to avoid ambiguous else clause.
* Makefile.in (procfs.o, proc-api.o, proc-events.o, proc-flags.o,
proc-why.o): Update dependencies.
* config/sparc/sun4sol2.mh (NATDEPFILES): Change proc_*.o files to
proc-*.o.
2000-01-17 Jason Molenda (jsm@bugshack.cygnus.com)
* configure.in (NEW_PROC_API): Fix Unixware-matching regexp.

* v850-tdep.c (v850_target_architecture_hook): Setup correct
machine id for disassembly.
2000-01-13 Jim Blandy <jimb@cygnus.com>
* i386-linux-nat.c (fill_gregset): Pass the correct arguments to
convert_to_regset, when regno indicates a specific register.
Thu Jan 13 23:34:17 EST 2000 Nicholas Duffek <nsd@cygnus.com>
