liboil-0.3.17
=============
New release of liboil out. Fixes a bunch of compile bugs.
***** WARNING *****
Liboil is now in maintenence-only mode. No new features will
be added, and bugs will be fixed according to their severity and
availablility of patches.
Users of liboil are recommended to switch to Orc
(http://code.entropywave.com/projects/orc/). Please contact
David Schleef <ds at schleef.org> about converting liboil functions
to Orc code -- in many cases this work has already been done.
Version bump
if's need else's. Fix previous commit
Wrap force_align_arg_pointer in HAVE_I386
Add AltiVec detection support for OpenBSD
Fix double free on failed arm_init
Add SSE detection support for OpenBSD
init: shortcut benchmarking, if there is only one runable implementation.
Add x86_64/amd64 to unaligned access whitelist
Add cris to unaligned access whitelist
remove ltdl.m4
Clean up function prototypes used for casting
bump version
Remove ' DATA' from symbol list
Add srcdir to includes for out-of-source builds
Fix cpu detection on OS/X
Add avg2_32xn_u8
Pkgsrc changes:
o Provide proper detection of altivec on NetBSD powerpc ports.
As an added bonus, this now builds on NetBSD/macppc 3.1 where
it didn't earlier.
This release merges lots of distributions patches and bug fixes
and adds new functionality used by the upcoming (now!) release
of Schroedinger-1.0.0.
pkgsrc note: someone with an arm (pun intended), or who knows how to
detect a "VFP" might want to tune the cpu feature detection code
changes:
- Finally integrated the SSE stack realignment wrappers and reenabled
the SSE intrinsics code.
- Migrated some new classes from Schroedinger for adding/subtracting
s16 and u8 values.
- Improved CPU detection on Solaris
- Remove XScale timestamping function, since it's not available from
user space
- Export oil_debug_print(), so the OIL_DEBUG() macros can be used
outside the library.
- Various new implementations.
changes:
- Lots of new classes and implementations were added for Schrödinger.
- Several i386 implementations also compile on amd64, so these were
copied over to a separate directory and are now enabled on amd64.
- Feature detection on amd64 has been fixed.
- All known startup warnings have been fixed.
- The core now handles arrays that are 'N plus a constant' in length.
- Wrap a bunch of functions in HAVE_UNALIGNED_ACCESS to indicate that
they require an architecture that handles unaligned access.
PR pkg/34886. Just #ifdef out the code on i386; it was disabled at
another layer anyway (due to alignment problems with any gcc on i386).
Thanks to Robert for testing.
-Make sure cpuid is read on amd64, to enable mmx/sse support. (We could
just assume it, but for the future this makes more sense.)
-bump PKGREVISION
the header name in the installed headers. Otherwise the packages that
depend on this one have to use the same hack as in the previous revision
of this file.
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.
Liboil is a library of simple functions that are optimized for various CPUs.
These functions are generally loops implementing simple algorithms, such as
converting an array of N integers to floating-point numbers or multiplying
and summing an array of N numbers. Such functions are candidates for
significant optimization using various techniques, especially by using
extended instructions provided by modern CPUs (Altivec, MMX, SSE, etc.).
Many multimedia applications and libraries already do similar things
internally. The goal of this project is to consolidate some of the code
used by various multimedia projects and also make optimizations easier to
use by a broader range of applications.
This is needed for the upcoming gstreamer 0.10.
