[B2-devel] [ANN] SheepShaver 2.2 snapshot (2005/03/21)

[Gwenole B. <gbe...@us...>]

Hi,

I placed new source tarballs and RPMs at:
<http://gwenole.beauchesne.free.fr/sheepshaver/>

Those interested in benchmarks can have a look at:
* nBench: <http://gwenole.beauchesne.free.fr/benchmarks/nbench.html>
* AltiVec Fractal Carbon:=20
<http://gwenole.beauchesne.free.fr/benchmarks/altivec.html>

User visible changes since 2004/07/07:
* Implement high-precision timings on POSIX systems
* Add other SDL keysym translations
* Add some SSE2 optimizations to the AltiVec emulation core
* Add port to FreeBSD 5.3 and NetBSD 2.0 systems (x86 tested)
* Add initial port to Windows with SDL graphics
* Fix interrupt handling, registers are now fully preserved
* Fix support for native execution on recent Linux/PPC systems
* Fix support for Gossamer ROMs (PowerMac G3 Beige)
* Fix crash in Apple Personal Diagnostics on MacOS 9
* Fix crash in Power Management on MacOS 9

Packager related changes:
* Fix FPU synthetic opcodes when compiled with -mtune=3Di686 and GCC >=3D=20=

3.3 (Cygwin)
* Fix build with recent enough assembler on x86-64 (Fedora Core 3,=20
Mandrakelinux 10.1)
* Fix AltiVec emulation core to be independent of GCC intrinsics thus=20
avoiding bugous generated code with e.g. Gentoo GCC 3.3 (it was fine=20
with MDK and SuSE gcc though).

Note about SDL graphics: it's currently suboptimal. Always prefer X11=20
graphics where applicable on standard X11 Unixish platforms: e.g.=20
Linux, NetBSD, etc. On the same platform, it was measured a up to 4x=20
times video performance boost with Linux/X11 instead of Windows/SDL.

Bye,
Gwenol=E9.=
