Example 6 with LLVMMemory

use of com.oracle.truffle.llvm.runtime.memory.LLVMMemory in project graal by oracle.

the class NativeProfiledMemMove method doInJava.

@Specialization(guards = "length <= MAX_JAVA_LEN")
protected void doInJava(Object target, Object source, long length, @Cached LLVMToNativeNode convertTarget, @Cached LLVMToNativeNode convertSource) {
    LLVMMemory memory = getLanguage().getLLVMMemory();

    LLVMNativePointer s = convertSource.executeWithTarget(source);
    long targetPointer = t.asNative();
    long sourcePointer = s.asNative();
    if (CompilerDirectives.injectBranchProbability(CompilerDirectives.LIKELY_PROBABILITY, length > 0 && sourcePointer != targetPointer)) {
        // sourcePointer + length <= targetPointer || targetPointer < sourcePointer
        if (CompilerDirectives.injectBranchProbability(CompilerDirectives.LIKELY_PROBABILITY, Long.compareUnsigned(targetPointer - sourcePointer, length) >= 0)) {
            copyForward(memory, targetPointer, sourcePointer, length);
        } else {
            copyBackward(memory, targetPointer, sourcePointer, length);
        }
    }
