|
|
|
- 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.
