Method Detail

isNearCall

public static boolean isNearCall(ForeignCallLinkage linkage)

Tests whether linkage can be called directly under all circumstances without the need for a scratch register. Note this is a pessimistic assumption: This may return false despite a near call/jump being adequate.

Parameters:

linkage - Foreign call description

Returns:

true if foreign call can be called directly and does not need a scratch register to load the address into.

directCall

public static int directCall(CompilationResultBuilder crb,
                             AArch64MacroAssembler masm,
                             InvokeTarget callTarget,
                             Register scratch,
                             LIRFrameState info)

directCall

public static int directCall(CompilationResultBuilder crb,
                             AArch64MacroAssembler masm,
                             InvokeTarget callTarget,
                             Register scratch,
                             LIRFrameState info,
                             Label label)

Returns:

the position of the emitted call instruction

indirectCall

public static int indirectCall(CompilationResultBuilder crb,
                               AArch64MacroAssembler masm,
                               Register dst,
                               InvokeTarget callTarget,
                               LIRFrameState info)

Returns:

the position of the emitted call instruction

directJmp

public static void directJmp(CompilationResultBuilder crb,
                             AArch64MacroAssembler masm,
                             InvokeTarget callTarget)

indirectJmp

directConditionalJmp

public static void directConditionalJmp(CompilationResultBuilder crb,
                                        AArch64MacroAssembler masm,
                                        InvokeTarget target,
                                        AArch64Assembler.ConditionFlag cond)
