Changes in Poly/ML Version 5.5
Major New Features
Storage management rewrite. The storage management system
has been almost completely rewritten. The garbage collector
is parallelised and a new mechanism has been introduced to
adjust the size of the heap. When space is very short an
extra pass may be triggered that merges immutable cells with
the same contents. Thanks to Tobias Nipkow and the Technical
University of Munich for support for this work.
PolyML.shareCommonData has been parallelised and now uses a
dynamic stack to avoid a possible segfault if the C stack
overflows with deep data structures.
There is now support for 64-bit on Windows using either
mingw or Visual Studio.
Added a PolyML.Statistics structure to extract information
about the current ML program or that running in another
process.
The standard "text" and "data" areas are now used for
exported object files. In particular this removes the need
for --segprot when linking the object files on Mac OS X with
previous versions.
libffi is now used for foreign function interface
(CInterface). Among other things this allows the full range
of types to be use on X86/64. A version of libffi is
included in the source but those packaging Poly/ML may
prefer to use the --with-system-libffi option to the
configure script to use the version installed on the
machine.
Withdrawn support for native-code on PPC and Sparc. The
configure script will now fall back to the interpreted
version on these platforms.
Minor Additions and Changes
Added G, M, K suffix to RTS arguments for --maxheap and --minheap.
Some changes to where "op" is allowed to conform more
closely to the Definition.
--debug and --logfile options. These allow fine control of
debugging information within the run-time system.
Added --error-exit option to terminate the top-level loop if
any command raises an exception.
Added PolyML.IntInf with gcd and lcm functions to use GMP's
gcd function if available.
Added PolyML.Compiler.allocationProfiling to work with
PolyML.profiling 4. This causes each full GC to print a
profile indicating where the currently live data has been
allocated.
Removed NetDB structure from the library since this was in
an early draft of the basis library but not in the final book.
Added PolyML.Codetree structure within PolyML. This allows
ML code to build intermediate code data structures and
generate machine code from them.
Added "--use FILENAME" command line argument to run a command
from a file before starting the main Read-Eval-Print loop.
Bug Fixes
Fixes related to Word32 on X86-64 and Word.~>>.
Vol allocation locking issue
Floating point box issue
Fix some functions in the Windows structure to match the
Basis Library definition
Fix a possible crash if a GC happened while another thread
was in foreign code.
Fix error in printer function for a datatype where the
effect of PolyML.print_depth depended on the posiition
of a constructor in the datatype.
Fix bug with flexible record handling.
Fix Real.fmt and Real.toString to conform to the Basis
Library definition.
Fix Real.abs with nan argument.
Fix IEEEReal.toString for nan argument.
Fix code-generator bug which resulted in incorrect result
for Real.nextAfter.
Fix bug the produced Subscript exceptions in stream IO.
for /etc/trusted-key.key, and uses that as a trust anchor if neither
-D nor -k options were specified. This feature is borrowed from
BIND's dig when it is compiled with SIGCHASE support. Bump
PKGREVISION.
Ensure that ldns is at least as new as this package.
I don't think there are specific fixes to drill in this update,
so this is an update to pull in all the library fixes from ldns,
since drill comes out of the ldns distribution.

The devel/libusb1 package is masked for both DragonFly and SunOS. This
cups package set libusb on by default which means cups fails to build
with no set options on those two platforms.
Add an OPSYS check which prevents libusb from even being offered as an
option on DragonFly and SunOS.
gdk-pixbuf2, gdk-pixbuf2-jasper, and gdk-pixbuf2-xlib have been manually
synced. Usually the base package would get updated and the others would
be forgotten resulting in an unnecessary mismatch.
Create a common makefile to permanently fix this problem.
Release 1.12.4 (2012-10-05 Chris Wilson <chris@chris-wilson.co.uk>)
===================================================================
More bugs, and more importantly, more fixes. On the cairo-gl side, we
have refinements to the MSAA compositor which enables hardware
acceleration of comparitively low-quality antialiasing - which is useful
in animations and on very high density screens. For cairo-xlib, we have
finally enabled SHM transport for image transfers to and from the X
server. A long standing required feature, SHM transport offers a notable
reduction in rendering latency by reducing the number of copies
required to upload image data - given hardware and driver support,
cairo-xlib can now perform zero copy uploads onto the GPU. And as usual
Adrian Johnson has been very busy fixing many different corner cases in
cairo-pdf, impoving opacity groups and font subsetting. Last, but not
least, for cairo-image Søren Sandmann Pedersen added support for
rendering glyphs to pixman and using that from within cairo. The new
glyph rendering facility reduces the overhead for setting up the
compositing operation, improving glyph thoughput for the image backend
by a factor of about 4. And before he did so, he also fixed up a few
bugs in the existing glyph rendering code. So many thanks to Andrea
Canciani, Adrian Johnson, Chuanbo Weng, Dongyeon Kim, Henry Song, Martin
Robinson, Søren Sandmann Pedersen and Uli Schlachter for their
contributions, finding and fixing bugs.

After discussing gcc47 build problems with postgresql developers, it
became apparent that the error was unique to DragonFly. It turns out
that DragonFly was using an older offsetof macro instead of the builtin
version provided by GCC.
Fixing the offsetof macro on DragonFly allowed the pre-patched psgsql 91
to build without issue. While the previous patches certainly don't hurt
anything, they are being removed to ease future maintenance.
The warning suppression fix is still valid, so the change to the pgsql
client makefile is being left in place.
