With GCC you can check for the __BMI2__ macro. This macro will be defined if the target supports BMI2 (e.g. -mbmi2 , -march=haswell ). 3.11 BMI2 Instructions ; mulx. MULX. Unsigned Multiply Without Affecting Flags ; pdep. PDEP. Parallel Bits Deposit ; pext. PEXT. Parallel Bits Extract ; rorx. RORX. V/N.E., BMI2, Parallel extract of bits from r64b using mask in r/m64, result is written to r64a. Instruction Operand Encoding ¶I saw on stackoverflow, there are “Parallel bit deposit and extract” instructions, which are part of BMI2 (Bit Manipulation Instruction Set 2). Bit Manipulation Instruction (BMI) Set 2.0. The reference is Intel 64 and IA-32 Architectures Software Developer's Manual Volume 2: Instruction Set BMI2, an x86-64 expansion of bit-manipulation instructions by Intel. Like BMI1, BMI2 employs VEX prefix encoding to support three-operand syntax with This class provides access to Intel BMI2 hardware instructions via intrinsics. 3.9 BMI2 Instructions ; mulx. MULX. Unsigned Multiply Without Affecting Flags ; pdep. PDEP. Parallel Bits Deposit ; pext. PEXT. Parallel Bits Extract ; rorx. RORX.
