I am creating a better kernel for Tiger 10.4.11 and encounter a problem to choose the best SSE3 emulator.
I have two its: VoodooSSE3 by mercurysquad and Previuos one (dunno who is the author: Mifki, Semtex, Netkas) released in 581_AMD_Intel_SSE2_SSE3_Kernel_Patcher at 27.10.2007. The last one presented in nasm sources and can be modified and compiled. VoodooSSE3 I have only in hex form.
581SSE3 is twice larger and three times slower but... it works better. dry.gif
See how this forum looks with the two kernels differs only in SSE3 parts
( both kernels available here)

581SSE3

As both emulators exits as hex codes I can't analyze its and make a corrections. But you see, they needed.
Is there any possibility to have the sources in form compilable by gcc 4.2?

And illegal instruction without args (simple trap 0xff)

What about SupplementalSSE3 emulations?

Slice , if i remember correctly the source was lost for the SSE3 Emu, perhaps Turbo or mercurysquad might have a copy and kaitek is missing.
