Method Summary

Modifier and Type	Method and Description
default boolean	divisionOverflowIsJVMSCompliant() Indicates whether the target platform complies with the JVM specification semantics for idiv and ldiv when the dividend is Integer.MAX_VALUE or Long.MAX_VALUE respectively and the divisor is -1.
default boolean	lowerAMD64(Node n) Performs AMD64-specific lowerings.
default Integer	smallestCompareWidth() Indicates the smallest width for comparing an integer value on the target platform.
default boolean	supportsBulkZeroing() Indicates whether this target platform supports bulk zeroing of arbitrary size.
default boolean	writesStronglyOrdered() Indicates whether all writes are ordered on this target platform.

Method Detail

divisionOverflowIsJVMSCompliant

default boolean divisionOverflowIsJVMSCompliant()

Description copied from interface: LoweringProvider

Indicates whether the target platform complies with the JVM specification semantics for idiv and ldiv when the dividend is Integer.MAX_VALUE or Long.MAX_VALUE respectively and the divisor is -1. The specified result for this case is the dividend.

Specified by:

divisionOverflowIsJVMSCompliant in interface LoweringProvider

smallestCompareWidth

default Integer smallestCompareWidth()

Description copied from interface: LoweringProvider

Indicates the smallest width for comparing an integer value on the target platform.

Specified by:

smallestCompareWidth in interface LoweringProvider

supportsBulkZeroing

default boolean supportsBulkZeroing()

Description copied from interface: LoweringProvider

Indicates whether this target platform supports bulk zeroing of arbitrary size.

Specified by:

supportsBulkZeroing in interface LoweringProvider

writesStronglyOrdered

default boolean writesStronglyOrdered()

Description copied from interface: LoweringProvider

Indicates whether all writes are ordered on this target platform.

Specified by:

writesStronglyOrdered in interface LoweringProvider

lowerAMD64

default boolean lowerAMD64(Node n)

Performs AMD64-specific lowerings. Returns true if the given Node n was lowered, false otherwise.
