Bump PKGREVISION
|
|
libocamlrun.a has a curses dependency on NetBSD. Patch the linker
invocation to allow adding platform specific options.
|
|
Add support for x86_64-*-DragonFly
Add support for native dynamic loading on both platforms
Add support for profiling on both platforms
Add ability to detect X11 in pkgsrc. This currently has no impact
because the makefile disables X11.
|
|
|
|
move PKGREVISION to each Makefile including the Makefile.common for
keep version number, and bump again for ocaml-graphics because the
previous bump resuited in downgrade.
|
|
|
|
|
|
Bump pkgrevision.
While I'm here: add a comment to patch-at explaining what it does.
Tested by
$ make install
$ cd work/ocaml-3.12.0/testsuite && gmake one DIR=tests/lib-dynlink-native
(Not in a build-env because that uses the wrappers, which don't let the
test suite see the installed OCaml files.)
This is only a workaround on NetBSD/{i386,amd64} for the problems of
OCaml PR#5049 <http://caml.inria.fr/mantis/view.php?id=5049>. (E.g.,
this workaround makes Coccinelle build on those platforms -- but it
still won't build on platforms with native compilation but no native
dynamic loading. Need to hack everything that uses dynlink to have
four compile-time cases -- {yes,no} {byte,nat}dynlink.)

pkglint clean-up

- to do this, and make the result runnable on pre-thumb arm, change
upstreams assembler snippets and stubs to use "mov pc,reg" instead
of the return/call-to-thumb-friendly "bx reg", which is not available
in non-thumb-enabled arm CPUs. Whether this is the way to go, or a
seperate "armt" architecture for ocaml is needed, needs to be discussed
with upstream.
Resulting compiler, when running its selftest suite, has 6 errors less than
the same on i386. Unison compiled natively with this passes its self-test.

natively (that is, only to byte-code).
This consists of two parts:
a) a patch to ocamldoc/Makefile to make it create the man pages using
the interpreted ocamldoc - this exists for both types of architectures,
so is safe. (This will be sent up-stream).
b) move a common shared library file to the common PLIST, and a lot of
files (natively compiled versions of the ML modules and natively compiled
versions of a few binaries) to PLIST.opt.
This has been build-tested on i386 (cross-compiled from amd64) and on
arm. unison builds and works.
"make test" shows the same amount of passed and failed tests (mostly
non-found libraries) as before; but this needs more investigation.
An additional issue to solve (with upstream) is that there's no easy way
to run the part of the test suite that would work on byte-code-only
architectures.

This unbreaks make package for darwin and linux

Some of the highlights in release 3.12 are:
* Polymorphic recursion is supported, using explicit type
declarations on the recursively-defined identifiers.
* First-class modules: module expressions can be embedded as
values of the core language, then manipulated like any other
first-class value, then projected back to the module level.
* New operator to modify a signature a posteriori: S with type
t := tau denotes signature S where the t type component is
removed and substituted by the type tau elsewhere.
* New notations for record expressions and record patterns:
{ lbl } as shorthand for { lbl = lbl }, and { ...; _ } marks
record patterns where some labels were intentionally omitted.
* Local open let open ... in ... now supported by popular demand.
* Type variables can be bound as type parameters to functions;
such types are treated like abstract types within the
function body, and like type variables (possibly generalized)
outside.
* The module type of construct enables to recover the module
type of a given module.
* Explicit method override using the method! keyword, with
associated warnings and errors.

(Changes that can break existing programs are marked with a "*" )
Language features:
- Addition of lazy patterns: "lazy <pat>" matches suspensions whose values,
after forcing, match the pattern <pat>.
- Introduction of private abbreviation types "type t = private <type-expr>",
for abstracting the actual manifest type in type abbreviations.
- Subtyping is now allowed between a private abbreviation and its definition,
and between a polymorphic method and its monomorphic instance.
Compilers:
- The file name for a compilation unit should correspond to a valid
identifier (Otherwise dynamic linking and other things can fail, and
a warning is emitted.)
* Revised -output-obj: the output name must now be provided; its
extension must be one of .o/.obj, .so/.dll, or .c for the
bytecode compiler. The compilers can now produce a shared library
(with all the needed -ccopts/-ccobjs options) directly.
- -dtypes renamed to -annot, records (in .annot files) which function calls
are tail calls.
- All compiler error messages now include a file name and location, for
better interaction with Emacs' compilation mode.
- Optimized compilation of "lazy e" when the argument "e" is
already evaluated.
- Optimized compilation of equality tests with a variant constant constructor.
- The -dllib options recorded in libraries are no longer ignored when
-use_runtime or -use_prims is used (unless -no_auto_link is
explicitly used).
- Check that at most one of -pack, -a, -shared, -c, -output-obj is
given on the command line.
- Optimized compilation of private types as regular manifest types
(e.g. abbreviation to float, float array or record types with only
float fields).
Native-code compiler:
- New port: Mac OS X / Intel in 64-bit mode (configure with -cc "gcc -m64").
- A new option "-shared" to produce a plugin that can be dynamically
loaded with the native version of Dynlink.
- A new option "-nodynlink" to enable optimizations valid only for code
that is never dynlinked (no-op except for AMD64).
- More aggressive unboxing of floats and boxed integers.
- Can select which assembler and asm options to use at configuration time.
Run-time system:
- New implementation of the page table describing the heap (two-level
array in 32 bits, sparse hashtable in 64 bits), fixes issues with address
space randomization on 64-bit OS (PR#4448).
- New "generational" API for registering global memory roots with the GC,
enables faster scanning of global roots.
(The functions are caml_*_generational_global_root in <caml/memory.h>.)
- New function "caml_raise_with_args" to raise an exception with several
arguments from C.
- Changes in implementation of dynamic linking of C code:
under Win32, use Alain Frisch's flexdll implementation of the dlopen
API; under MacOSX, use dlopen API instead of MacOSX bundle API.
- Programs may now choose a first-fit allocation policy instead of
the default next-fit. First-fit reduces fragmentation but is
slightly slower in some cases.
Standard library:
- Parsing library: new function "set_trace" to programmatically turn
on or off the printing of a trace during parsing.
- Printexc library: new functions "print_backtrace" and "get_backtrace"
to obtain a stack backtrace of the most recently raised exception.
New function "record_backtrace" to turn the exception backtrace mechanism
on or off from within a program.
- Scanf library: fine-tuning of meta format implementation;
fscanf behaviour revisited: only one input buffer is allocated for any
given input channel;
the %n conversion does not count a lookahead character as read.
Other libraries:
- Dynlink: on some platforms, the Dynlink library is now available in
native code. The boolean Dynlink.is_native allows the program to
know whether it has been compiled in bytecode or in native code.
- Bigarrays: added "unsafe_get" and "unsafe_set"
(non-bound-checking versions of "get" and "set").
- Bigarrays: removed limitation "array dimension < 2^31".
- Labltk: added support for TK 8.5.
- Num: added conversions between big_int and int32, nativeint, int64.
More efficient implementation of Num.quo_num and Num.mod_num.
- Threads: improved efficiency of mutex and condition variable operations;
improved interaction with Unix.fork (PR#4577).
- Unix: added getsockopt_error returning type Unix.error.
Added support for TCP_NODELAY and IPV6_ONLY socket options.
- Win32 Unix: "select" now supports all kinds of file descriptors.
Improved emulation of "lockf" (PR#4609).
Tools:
- ocamldebug now supported under Windows (MSVC and Mingw ports),
but without the replay feature. (Contributed by Dmitry Bely
and Sylvain Le Gall at OCamlCore with support from Lexifi.)
- ocamldoc: new option -no-module-constraint-filter to include functions
hidden by signature constraint in documentation.
- ocamlmklib and ocamldep.opt now available under Windows ports.
- ocamlmklib no longer supports the -implib option.
- ocamlnat: an experimental native toplevel (not built by default).
Camlp4:
* programs linked with camlp4lib.cma now also need dynlink.cma.

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

as well. In this case, we fall into the SYS_elf branch together
with Linux, but we need a few other specifics to access registers
in the sigcontext.

Add amd64 to that list. Bump revision of ocaml-graphics. Make ocaml
itself and ocaml-graphics destdir safe.
