GCC supports FMA4 with -mfma4 since version 4.5.0 [25] and FMA3 with -mfma since version 4.7.0. Microsoft Visual C++ 2010 SP1 supports FMA4 instructions. [26] Microsoft Visual C++ 2012 supports FMA3 instructions (if the processor also supports AVX2 instruction set extension). Microsoft Visual C++ since VC 2013; PathScale supports FMA4 with ...
The DS2 and DS3 registers (which are specific to the NEC V55) act similar to regular x86 real mode segment registers except that they are left-shifted by 8 rather than 4, enabling access to 16MB of memory. Block transfer instructions, such as MOVBKW, can access the 16MB memory space by simultaneously prefixing with DS2 and DS3.
The x86 instruction set has several times been extended with SIMD (Single instruction, multiple data) instruction set extensions.These extensions, starting from the MMX instruction set extension introduced with Pentium MMX in 1997, typically define sets of wide registers and instructions that subdivide these registers into fixed-size lanes and perform a computation for each lane in parallel.
Instruction set extensions that have been added to the x86 instruction set in order to support hardware virtualization.These extensions provide instructions for entering and leaving a virtualized execution context and for loading virtual-machine control structures (VMCSs), which hold the state of the guest and host, along with fields which control processor behavior within the virtual machine.

The x86 instruction set refers to the set of instructions that x86-compatible microprocessors support. The instructions are usually part of an executable program, often stored as a computer file and executed on the processor. The x86 instruction set has been extended several times, introducing wider registers and datatypes as well as new ...
