Objective Caml 2.01 released

Objective Caml 2.01 released

[Xavier Leroy]

Objective Caml 2.01 has just been released -- right in time for Christmas.
This is a bug-fix release that corrects all known 2.00 bugs, and adds
some convenience features (see below for a complete list of changes)
as well as a couple of new ports (Linux/StrongARM, IRIX/-n32).

It is available from the usual places:
        http://caml.inria.fr/ocaml/distrib.html
        ftp://ftp.inria.fr/lang/caml-light/

For general info on Objective Caml, see http://caml.inria.fr/ocaml/

Please direct queries and bug reports to caml-light@inria.fr
and general discussions to the mailing-list caml-list@inria.fr or the
comp.lang.ml newsgroup.

Objective Caml 2.01:
--------------------

* Typing:
  - Added warning for expressions of the form "a; b" where a does not have
    type "unit"; catches silly mistake such as
    "record.lbl = newval; ..." instead of "record.lbl <- newval; ...".
  - Typing bug in "let module" fixed.

* Compilation:
  - Fixed bug in compilation of recursive and mutually recursive classes.
  - Option -w to turn specific warnings on/off.
  - Option -cc to choose the C compiler used with ocamlc -custom and ocamlopt.

* Bytecode compiler and bytecode interpreter:
  - Intel x86: removed asm declaration causing "fixed or forbidden register
    spilled" error with egcs and gcc 2.8 (but not with gcc 2.7, go figure).
  - Revised handling of debugging information, allows faster linking with -g.

* Native-code compiler:
  - Fixed bugs in integer constant propagation.
  - Out-of-bound accesses in array and strings now raise an Invalid_argument
    exception (like the bytecode system) instead of stopping the program.
  - Corrected scheduling of bound checks.
  - Port to the StrongARM under Linux (e.g. Corel Netwinder).
  - I386: fixed bug in profiled code (ocamlopt -p).
  - Mips: switched to -n32 model under IRIX; dropped the Ultrix port.
  - Sparc: simplified the addressing modes, allows for better scheduling.
  - Fixed calling convention bug for Pervasives.modf.

* Toplevel:
  - #trace works again.
  - ocamlmktop: use matching ocamlc, not any ocamlc from the search path.

* Memory management:
  - Fixed bug in heap expansion that could cause the GC to loop.

* C interface:
  - New macros CAMLparam... and CAMLlocal... to simplify the handling
    of local roots in C code.
  - Simplified procedure for allocating and filling Caml blocks from C.
  - Declaration of string_length in <caml/mlvalues.h>.

* Standard library:
  - Module Format: added {get,set}_all_formatter_output_functions,
    formatter_of_out_channel, and the control sequence @<n> in printf.
  - Module List: added mem_assoc, mem_assq, remove, removeq.
  - Module Pervasives: added float_of_int (synonymous for float),
    int_of_float (truncate), int_of_char (Char.code), char_of_int (Char.chr),
    bool_of_string.
  - Module String: added contains, contains_from, rcontains_from.

* Unix library:
  - Unix.lockf: added F_RLOCK, F_TRLOCK; use POSIX locks whenever available.
  - Unix.tc{get,set}attr: added non-standard speeds 57600, 115200, 230400.
  - Unix.chroot: added.

* Threads:
  - Bytecode threads: improved speed of I/O scheduling.
  - Native threads: fixed a bug involving signals and exceptions
    generated from C.

* The "str" library:
  - Added Str.string_partial_match.
  - Bumped size of internal stack.

* ocamlyacc: emit correct '# lineno' directive for prelude part of .mly file.

* Emacs editing mode: updated with Jacques Garrigue's newest code.

* Windows port:
  - Added support for the "-cclib -lfoo" option (instead of
     -cclib /full/path/libfoo.lib as before).
  - Threads: fixed a bug at initialization time.

* Macintosh port: source code for Macintosh application merged in.
