Method Detail

directCall

public static int directCall(CompilationResultBuilder crb,
                             AMD64MacroAssembler masm,
                             InvokeTarget callTarget,
                             Register scratch,
                             boolean align,
                             LIRFrameState info)

Parameters:

scratch - register to use for call target address when emitting a far call

align - indicates whether the displacement operand of an immediate call instruction must be 4-byte aligned

Returns:

the position of the emitted call instruction

directInlineCacheCall

public static void directInlineCacheCall(CompilationResultBuilder crb,
                                         AMD64MacroAssembler masm,
                                         InvokeTarget callTarget,
                                         CompilationResult.MarkId markId,
                                         long nonOopBits,
                                         LIRFrameState info)

Emits a direct call instruction, immediately preceded by a mov instruction. This is used for emitting HotSpot inline cache call. The runtime will patch the mov instruction to load the cached receiver type, which will be used in [Entry Point] code section for receiver type check.

Parameters:

nonOopBits - placeholder bit pattern for inline cache receiver type patching

directJmp

public static void directJmp(CompilationResultBuilder crb,
                             AMD64MacroAssembler masm,
                             ForeignCallLinkage target,
                             Register scratch)

recordDirectCall

public static void recordDirectCall(CompilationResultBuilder crb,
                                    AMD64MacroAssembler masm,
                                    ForeignCallLinkage target,
                                    int before)

indirectCall

public static int indirectCall(CompilationResultBuilder crb,
                               AMD64MacroAssembler masm,
                               Register dst,
                               InvokeTarget callTarget,
                               LIRFrameState info)

indirectCall

public static int indirectCall(CompilationResultBuilder crb,
                               AMD64MacroAssembler masm,
                               Register dst,
                               InvokeTarget callTarget,
                               LIRFrameState info,
                               boolean mitigateDecodingAsDirectCall)

Returns:

the position of the emitted call instruction
