Example 1 with AMD64CCall

use of org.graalvm.compiler.lir.amd64.AMD64CCall in project graal by oracle.

the class AMD64HotSpotLIRGenerator method emitCCall.

    // RAX contains the length of the varargs
    PrimitiveConstant intConst = JavaConstant.forInt(numberOfFloatingPointArguments);
    AllocatableValue numberOfFloatingPointArgumentsRegister = AMD64.rax.asValue(LIRKind.value(AMD64Kind.DWORD));
    emitMoveConstant(numberOfFloatingPointArgumentsRegister, intConst);
    for (int i = 0; i < args.length; i++) {
