- Added support for AVX and AVX2 instructions emulation, to enable configure
...
with --enable-avx option. When compiled in, AVX still has to be enabled
using .bochsrc CPUID option. AVX2 FMA instructions still not implemented.
- Added support for Bit Manipulation Instructions (BMI) emulation. The BMI
instructions support can be enabled using .bochsrc CPUID option.
