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.

0.1.0 (3 March 2007)
General improvements:
* Add on-demand compilation driver (Aleksey Demakov, Klaus Treichel).
* Add jit_function_from_vtable_pointer function (Klaus Treichel).
* Add jit_insn_mark_breakpoint_variable function (Radek Polak).
* Add signal handlers (Kirill Kononenko).
* Add JIT_OPTION_POSITION_INDEPENDENT context option (not supported
by the backends yet) (Aleksey Demakov).
* Add function indirectors (Klaus Treichel).
* Allocate function redirectors and indirectors in the code cache
(Aleksey Demakov).
* Use mmap to allocate executable memory where available
(Klaus Treichel).
* Now can dump to any stream not just stdout and stderr (Radek Polak).
* Use a global lock during context initialization (Aleksey Demakov).
* Fix problems that take place after compilation is restarted on cache
page overflow (Aleksey Demakov).

and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto

of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.

RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).

* Honor PKGINFODIR and EMACS_INFOPREFIX.

makeinfo if no native makeinfo executable exists. Honor TEXINFO_REQD
when determining whether the native makeinfo can be used.
* Remove USE_MAKEINFO and replace it with USE_TOOLS+=makeinfo.
* Get rid of all the "split" argument deduction for makeinfo since
the PLIST module already handles varying numbers of split info files
correctly.
NOTE: Platforms that have "makeinfo" in the base system should check
that the makeinfo entries of pkgsrc/mk/tools.${OPSYS}.mk are
correct.

developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.

Changes:
* Pluggable object models.
* Problems with "gen-apply" on Win32 systems.
* Optimize "if true goto" into "goto".
* Peephole optimization on branches.
* Adjust ARM codegen macros to support branch elimination instructions.
* Redesign exception handling to use "setjmp" everywhere.
* Remove C++ code from "libjit.so" so that it is a pure C library.
* Use computed goto's in the interpreter if the compiler supports them.
* Don't allow conditional branches to jump out of exception contexts.
* Block movement to allow initialization code to be moved to the start
of a function, or loop condition code to be moved to the end.
* Rewrite the exception region routines to make them easier to use.
* Add the "gen-sel" program, for creating instruction selectors.
* Write instruction selectors for x86 and ARM (only x86 is enabled).
* Portability fixes for ARM, PPC, Alpha, IA64, and amd64.
* Clarify the description of LLVM, at the request of LLVM's author.
* Deferred argument popping after function calls.
* Add "--enable-interpreter" to force the interpreter to be used.
* Implement a simple global register allocator based on usage counts.
* Recognise increment and decrement idioms.
* Align cache flushes properly (Miroslaw Dobrzanski-Neumann).
* Querying of x86 cpuid where necessary.
* Add a constant pool for ARM, to make constant loads more efficient.
* Handle register pairs for 64-bit values properly.
* Support for parameter areas on the stack, to reduce push/pop overhead.
* Avoid unnecessary register spills if a value won't be used again.
* Implement tail calls from a function to itself.
* Optimize x86 prologs and epilogs to avoid doing unnecessry work.
* Centralise the code that handles parameter passing.
* Support for parallel builds.

in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
|

All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".

The libjit library implements Just-In-Time compilation functionality. Unlike
other JIT's, this one is designed to be independent of any particular virtual
machine bytecode format or language. The hope is that Free Software projects
can get a leg-up on proprietry VM vendors by using this library rather than
spending large amounts of time writing their own JIT from scratch.
This JIT is also designed to be portable to multiple archictures. If you run
libjit on a machine for which a native code generator is not yet available,
then libjit will fall back to interpreting the code. This way, you don't need
to write your own interpreter for your bytecode format if you don't want to.
