Constructor Detail

StoreReleaseOp

public StoreReleaseOp(AArch64Kind accessKind,
                      AArch64AddressValue address,
                      AllocatableValue input,

Method Detail

emitMemAccess

protected int emitMemAccess(CompilationResultBuilder crb,
                            AArch64MacroAssembler masm)

Emit the memory access.

Returns:

The buffer position before the memory access was issued. Normally this will be the same as the position of the memory access; however, if the memory access was merged with a previous access, then it will be the position after the access.

getAccessKind

public AArch64Kind getAccessKind()

mergingAllowed

protected boolean mergingAllowed(CompilationResultBuilder crb,
                                 int memPosition)

Checks whether the current memory access could be merged with the prior memory access.
