Class X86.Bmi1
bmi1 intrinsics
Namespace: Unity.Burst.Intrinsics
Syntax
public static class Bmi1 : objectProperties
| Name | Description |
|---|---|
| IsBmi1Supported | Evaluates to true at compile time if bmi1 intrinsics are supported. Burst ties bmi1 support to AVX2 support to simplify feature sets to support. |
Methods
| Name | Description |
|---|---|
| andn_u32(UInt32, UInt32) | Compute the bitwise NOT of 32-bit integer a and then AND with b, and store the results in dst. |
| andn_u64(UInt64, UInt64) | Compute the bitwise NOT of 64-bit integer a and then AND with b, and store the results in dst. |
| bextr_u32(UInt32, UInt32, UInt32) | Extract contiguous bits from unsigned 32-bit integer a, and store the result in dst. Extract the number of bits specified by len, starting at the bit specified by start. |
| bextr_u64(UInt64, UInt32, UInt32) | Extract contiguous bits from unsigned 64-bit integer a, and store the result in dst. Extract the number of bits specified by len, starting at the bit specified by start. |
| bextr2_u32(UInt32, UInt32) | Extract contiguous bits from unsigned 32-bit integer a, and store the result in dst. Extract the number of bits specified by bits 15:8 of control, starting at the bit specified by bits 0:7 of control.. |
| bextr2_u64(UInt64, UInt64) | Extract contiguous bits from unsigned 64-bit integer a, and store the result in dst. Extract the number of bits specified by bits 15:8 of control, starting at the bit specified by bits 0:7 of control.. |
| blsi_u32(UInt32) | Extract the lowest set bit from unsigned 32-bit integer a and set the corresponding bit in dst. All other bits in dst are zeroed, and all bits are zeroed if no bits are set in a. |
| blsi_u64(UInt64) | Extract the lowest set bit from unsigned 64-bit integer a and set the corresponding bit in dst. All other bits in dst are zeroed, and all bits are zeroed if no bits are set in a. |
| blsmsk_u32(UInt32) | Set all the lower bits of dst up to and including the lowest set bit in unsigned 32-bit integer a. |
| blsmsk_u64(UInt64) | Set all the lower bits of dst up to and including the lowest set bit in unsigned 64-bit integer a. |
| blsr_u32(UInt32) | Copy all bits from unsigned 32-bit integer a to dst, and reset (set to 0) the bit in dst that corresponds to the lowest set bit in a. |
| blsr_u64(UInt64) | Copy all bits from unsigned 64-bit integer a to dst, and reset (set to 0) the bit in dst that corresponds to the lowest set bit in a. |
| tzcnt_u32(UInt32) | Count the number of trailing zero bits in unsigned 32-bit integer a, and return that count in dst. |
| tzcnt_u64(UInt64) | Count the number of trailing zero bits in unsigned 64-bit integer a, and return that count in dst. |
