Release 1.15:
|
|
-------------
|
|
|
|
* Caml Special Light now runs under Windows NT and 95. Many thanks to
|
|
Kevin Gallo (Microsoft Research) who contributed his initial port.
|
|
|
|
* csllex now generates tables for a table-driven automaton.
|
|
The resulting lexers are smaller and run faster.
|
|
|
|
* Completely automatic configuration script.
|
|
|
|
* Typing: more stringent checking of module type definitions against
|
|
manifest module type specifications.
|
|
|
|
* Toplevel: recursive definitions of values now working.
|
|
|
|
* Native-code compiler, all platforms:
|
|
toplevel "let"s with refutable patterns now working;
|
|
fixed bug in assignment to float record fields;
|
|
direct support for floating-point negation and absolute value.
|
|
|
|
* Native-code compiler, x86: fixed bug with tail calls (with more than
|
|
4 arguments) from a function with a one-word stack frame.
|
|
|
|
* Native-code compiler, Sparc: problem with -compact fixed.
|
|
|
|
* Thread library: support for non-blocking writes; scheduler revised.
|
|
|
|
* Unix library: bug in gethostbyaddr fixed; bounds checking for read,
|
|
write, etc.
|
|
|
|
Release 1.14:
|
|
-------------
|
|
|
|
* cslopt ported to the PowerPC/RS6000 architecture. Better support for
|
|
AIX in the bytecode system as well.
|
|
|
|
* cslopt, all platforms: fixed bug in live range splitting around catch/exit.
|
|
|
|
* cslopt for the Intel (floating-point wars, chapter 4):
|
|
implemented Ershov's algorithm to minimize floating-point stack usage;
|
|
out-of-order pops fixed.
|
|
|
|
* Several bug fixes in callbacks and signals.
|
|
|
|
Release 1.13:
|
|
-------------
|
|
|
|
* Pattern-matching compilation revised to factor out accesses inside
|
|
matched structures.
|
|
|
|
* Callbacks and signals now supported in cslopt.
|
|
Signals are only detected at allocation points, though.
|
|
Added callback functions with 2 and 3 arguments.
|
|
|
|
* More explicit error messages when a native-code program aborts due
|
|
to array or string bound violations.
|
|
|
|
* In patterns, "C _" allowed even if the constructor C has several arguments.
|
|
|
|
* && and || allowed as alternate syntax for & and or.
|
|
|
|
* cslopt for the Intel: code generation for floating-point
|
|
operations entirely redone for the third time (a pox on whomever at
|
|
Intel decided to organize the floating-point registers as a stack).
|
|
|
|
* cslopt for the Sparc: don't use Sparc V8 smul and sdiv instructions,
|
|
emulation on V7 processors is abysmal.
|
|
|
|
Release 1.12:
|
|
-------------
|
|
|
|
* Fixed an embarrassing bug with references to floats.
|
|
|
|
Release 1.11:
|
|
-------------
|
|
|
|
* Streams and stream parsers a la Caml Light are back (thanks to
|
|
Daniel de Rauglaudre).
|
|
|
|
* User-level concurrent threads, with low-level shared memory primitives
|
|
(locks and conditions) as well as channel-based communication primitives
|
|
with first-class synchronous events, in the style of Reppy's CML.
|
|
|
|
* The native-code compiler has been ported to the HP PA-RISC processor
|
|
running under NextStep (sorry, no HPUX, its linker keeps dumping
|
|
core on me).
|
|
|
|
* References not captured in a function are optimized into variables.
|
|
|
|
* Fixed several bugs related to exceptions.
|
|
|
|
* Floats behave a little more as specified in the IEEE standard
|
|
(believe it or not, but x < y is not the negation of x >= y).
|
|
|
|
* Lower memory consumption for the native-code compiler.
|
|
|
|
Release 1.10:
|
|
-------------
|
|
|
|
* Many bug fixes (too many to list here).
|
|
|
|
* Module language: introduction of a "with module" notation over
|
|
signatures for concise sharing of all type components of a signature;
|
|
better support for concrete types in signatures.
|
|
|
|
* Native-code compiler: the Intel 386 version has been ported to
|
|
NextStep and FreeBSD, and generates better code (especially for
|
|
floats)
|
|
|
|
* Tools and libraries: the Caml Light profiler and library for
|
|
arbitrary-precision arithmetic have been ported (thanks to John
|
|
Malecki and Victor Manuel Gulias Fernandez); better docs for the Unix
|
|
and regexp libraries.
|
|
|
|
Release 1.07:
|
|
-------------
|
|
|
|
* Syntax: optional ;; allowed in compilation units and structures
|
|
(back by popular demand)
|
|
|
|
* cslopt:
|
|
generic handling of float arrays fixed
|
|
direct function application when the function expr is not a path fixed
|
|
compilation of "let rec" over values fixed
|
|
multiple definitions of a value name in a module correctly handled
|
|
no calls to ranlib in Solaris
|
|
|
|
* csltop: #trace now working
|
|
|
|
* Standard library: added List.memq; documentation of Array fixed.
|
|
|
|
Release 1.06:
|
|
-------------
|
|
|
|
* First public release.
