WebEach class only has one userData field, ... An important caveat to determinism is the state of the x87 FPU on 32-bit Intel/AMD platforms. Some compilers produce x87 floating point instructions even when configured to prefer SSE instructions, and the results of those operations may depend on the state of the x87 control word. ... WebNov 30, 2024 · Instruction pointer: the x87 state machine apparently holds its own copy of the current x87 instruction; Last instruction opcode: this is apparently distinct from the x87 opcode, and has its own register; Registers in this group: 14. Running total: 92. MMX. MMX was Intel’s first attempt at consumer SIMD in their x86 chips, released back in 1997.

WebThe x87 coprocessor, if present, provides support for floating-point arithmetic. The coprocessor provides eight data registers, each holding one 80-bit floating-point value (1 sign bit, 15 exponent bits, 64 mantissa bits) - these registers are organized as a stack, with the top-of-stack register referred to as "st" or "st(0)", and the other ...
