Class AMD64BaseAssembler.EVEXPrefixConfig

java.lang.Object

org.graalvm.compiler.asm.amd64.AMD64BaseAssembler.EVEXPrefixConfig

Enclosing class:

AMD64BaseAssembler

public static final class AMD64BaseAssembler.EVEXPrefixConfig
extends Object

Contains flag values for the EVEX prefix used in AVX-512 instructions.

AMD64BaseAssembler.EVEXPrefixConfig.Z0/AMD64BaseAssembler.EVEXPrefixConfig.Z1 denote possible values of the z-bit that may be used by AVX-512 instructions to signal zeroing/merging. A set flag indicates that all lanes that are not selected by the opmask are zeroed in the result register. Per default, those values are merged (i.e. values in the result register in the corresponding lanes remain).

AMD64BaseAssembler.EVEXPrefixConfig.B0/AMD64BaseAssembler.EVEXPrefixConfig.B1 denote the values of the b-bit that may be used by AVX-512 instructions to modify the rounding mode or signal broadcasting in load instructions. The semantics of the flag value depend on the actual instruction.
