Mon Aug 30 17:36:41 CEST 2010 - vuntz@opensuse.org
|
||
|
||
- Update to version 0.4.8:
|
||
+ Fix Windows and OS/X builds
|
||
+ Improve behavior in failure cases
|
||
+ Major improvements for Altivec backend
|
||
+ Significant documentation additions
|
||
+ Memory for executable code storage is now handled in a much
|
||
more controlled manner, and it's now possible to reclaim this
|
||
memory after it's no longer needed.
|
||
+ A few more 64-bit opcodes have been added, mostly related to
|
||
arithmetic on floating point values.
|
||
+ The orcc tool now handles 64-bit and floating point parameters
|
||
and constants.
|
||
- Add baselibs.conf.

|
||
|
||
- Update to version 0.4.7:
|
||
+ Lots of specialized new opcodes and opcode prefixes.
|
||
+ Important fixes for ARM backend
|
||
+ Improved emulation of programs (much faster)
|
||
+ Implemented fallback rules for almost all opcodes for SSE and
|
||
NEON backends
|
||
+ Performance improvements for SSE and NEON backends.
|
||
+ Many fixes to make larger programs compile properly.
|
||
+ 64-bit data types are now fully implemented, although there are
|
||
few operations on them.
|
||
+ Loads and stores are now handled by separate opcodes (loadb,
|
||
storeb, etc). For compatibility, these are automatically
|
||
included where necessary. This allowed new specialized loading
|
||
opcodes, for example, resampling a source array for use in
|
||
scaling images.
|
||
+ Opcodes may now be prefixed by "x2" or "x4", indicating that a
|
||
operation should be done on 2 or 4 parts of a proportionally
|
||
larger value. For example, "x4 addusb" performs 4 saturated
|
||
unsigned additions on each of the four bytes of 32-bit
|
||
quantities. This is useful in pixel operations.
|
||
+ The MMX backend is now (semi-) automatically generated from the
|
||
SSE backend.
|
||
+ The orcc tool has a new option "-inline", which creates inline
|
||
versions of the Orc stub functions. The orcc tool also
|
||
recognizes a new directive ‘.init’, which instructs the
|
||
compiler to generate an initialization function, which when
|
||
called at application init time, compiles all the generated
|
||
functions. This allows the generated stub functions to avoid
|
||
checking if the function has already been compiled. The use of
|
||
these two features can dramatically decrease the cost of
|
||
calling Orc functions.

|
||
|
||
- Update to version 0.4.6:
|
||
+ Various fixes to make Orc more portable
|
||
+ Major performance improvements to NEON backend
|
||
+ Minor performance improvements to SSE backend
|
||
+ Major improvements to ARM backend, now passes regression tests.
|
||
+ The defaults for floating point operations have been changed
|
||
somewhat: NANs are handled more like the IEEE 754 standard, and
|
||
denormals in operations are treated as zeros. The NAN changes
|
||
causes certain SSE operations to be slightly slower, but produce
|
||
less surprising results. Treating denormals as zero has effects
|
||
ranging from “slightly faster” to “now possible”.
|
||
+ New tool: orc-bugreport. Mainly this is to provide a limited
|
||
testing tool in the field, especially for embedded targets
|
||
which would not have access to the testsuite that is not
|
||
installed.
|
||
+ The environment variable ORC_CODE can now be used to adjust
|
||
some code generation. See orc-bugreport -help for details.
|
||
+ orcc has a new option to generate code that is compatible with
|
||
older versions of Orc.
|
||
+ New NEON detection relies on Linux 2.6.29 or later.
|
||
- Changes from version 0.4.5:
|
||
+ Many small improvements related to converting GStreamer from
|
||
liboil to Orc.
|
||
+ The major addition in this release is the mainstreaming of
|
||
the NEON backend, made possible by Nokia.
|
||
+ There is a new experimental option to ./configure,
|
||
--enable-backend, which allows you to choose a single code
|
||
generation backend to include in the library. This is mostly
|
||
useful for embedded systems, and is not recommended in general.
|
||
- Do not call autogen.sh and remove workaround for doc generation.
