Examples with Isolate org.graalvm.nativeimage.Isolate used on opensource projects

Example 1 with Isolate

use of org.graalvm.nativeimage.Isolate in project graal by oracle.

the class PosixCEntryPointSnippets method enterSnippet.

@Snippet

    Isolate isolate;
    if (MultiThreaded.getValue()) {
        if (thread.isNull()) {
            return Errors.NULL_ARGUMENT;
        }
        writeCurrentVMThread(thread);
        isolate = PosixVMThreads.IsolateTL.get(thread);
    } else {

        } else if (!thread.equal(CEntryPointSetup.SINGLE_THREAD_SENTINEL)) {
            return Errors.UNATTACHED_THREAD;
        }
        isolate = (Isolate) ((Word) thread).subtract(CEntryPointSetup.SINGLE_ISOLATE_TO_SINGLE_THREAD_ADDEND);
    }
    if (UseHeapBaseRegister.getValue()) {
