Latest News : February 5, 2017

In the latest Mini vMac Development source snapshot I've experimented with the “global register variable” feature of GCC 4.7.4, in the x86-64 version of Mini vMac, to make better use of the 8 extra registers (as compared to x86-32). The compiler doesn't seem to generate very good code for this feature, but the result is still faster then when not using it. The x86-64 version of Mini vMac 3.5 is now 10 to 20 percent faster than the assembly language of Mini vMac 3.4.1 for x86-32 (there was no x86-64 assembly language).
