isaextensions

Specifies a list of supported instruction set architecture extensions.

isaextensions { "values" }

values is one of:

Value	Description
`MOVBE`	Move after byte-swap instruction (transfers data with endianness conversion)
`POPCNT`	Population count instruction (counts set bits in a register)
`PCLMUL`	Carry-less multiply instruction (PCLMULQDQ) for polynomial multiplication
`LZCNT`	Count leading zeros instruction (returns number of leading zero bits)
`BMI`	Bit Manipulation Instruction set 1 (bit-field and bit-test helpers like ANDN, BLSI)
`BMI2`	Bit Manipulation Instruction set 2 (advanced bit ops like MULX, PDEP, PEXT)
`F16C`	Half-precision floating-point conversion instructions (float16 <-> float32)
`AES`	AES-NI instructions for hardware-accelerated AES encryption/decryption
`FMA`	Fused multiply-add instructions (FMA3: 3-operand fused multiply-add)
`FMA4`	AMD 4-operand fused multiply-add instruction set (FMA4)
`RDRND`	Hardware random number generator instruction (RDRAND)
