[B2-devel] SheepShaver with AltiVec emulation in CVS

[Gwenole B. <gb...@di...>]

Hi,

I have just committed AltiVec emulation to CVS. It is *not* optimized 
yet but provides already a speed up factor of 1.8x on AltiVec Fractal 
Carbon v1.2. Now that we have AltiVec emulation, I also set the PVR to 
match a 7400 (G4) processor. Tell me if this causes problems.

I have not tried a SheepShaver build on x86 yet, but the Kheperix 
testsuite was expanded to include more than 800K testcases, and they 
all pass on both ppc & x86. So, it should just work.

Note that I make intensive use of templates. i.e. only 15 templates 
expand to the whole 150+ instruction handlers. That said, you will need 
a C++ compiler good enough to cope with that, both ISO C++ conformance 
wise and optimization wise. FYI, I used gcc 3.2.2.

Bye,
Gwenole.
