Is Intel® Transactional Synchronization Extensions New Instruction (TSX-NI) difference from Intel TSX?

问题 I found on Intel's page https://ark.intel.com/products/97123/Intel-Core-i5-7500-Processor-6M-Cache-up-to-3_80-GHz that this processor support TSX-NI technology but I can't find any information about it on google. Is it the same as Intel TSX. If it is difference, then how I can use it. Sorry for my bad English! :) 回答1: It seems just a marketing embellishment. I found no references to "TSX-NI" nor on the Internet nor in the Intel manuals nor in the Intel ISA extensions manual. Quoting Intel [1]

Using a forwardRef component with children in TypeScript

由 孤者浪人 提交于 2019-12-09 17:21:45
问题 Using @types/react 16.8.2 and TypeScript 3.3.1. I lifted this forward refs example straight from the React documentation and added a couple type parameters: const FancyButton = React.forwardRef<HTMLButtonElement>((props, ref) => ( <button ref={ref} className="FancyButton"> {props.children} </button> )); // You can now get a ref directly to the DOM button: const ref = React.createRef<HTMLButtonElement>(); <FancyButton ref={ref}>Click me!</FancyButton>; I get the following error in the last

Extending HTML elements in React and TypeScript while preserving props

由 守給你的承諾、 提交于 2019-12-09 05:06:01
问题 I just can't wrap my head around this I guess, I've tried probably half a dozen times and always resort to any ... Is there a legitimate way to start with an HTML element, wrap that in a component, and wrap that in another component such that the HTML props pass through everything? Essentially customizing the HTML element? For example, something like: interface MyButtonProps extends React.HTMLProps<HTMLButtonElement> {} class MyButton extends React.Component<MyButtonProps, {}> { render() {

interface states and props in typescript react

由 懵懂的女人 提交于 2019-12-03 03:39:26
问题 I'm working on a project that uses typescript as well as react and am new to both. My questions is about interface in typescript and how that relates to props and states. What is actually happening? My application doesnt run at all unless I declare interface props and states, but Im using states through the react constructor function and I've seen examples where all of that information would go into 'interface MyProps' or 'interface MyStates' take this code for example "use strict"; import *

Does an aborted xbegin transaction restore the stack context that existed at the xbegin start?

由 笑着哭i 提交于 2019-11-28 12:08:19
问题 I am interested in encapsulating a transactional xbegin and xend inside XBEGIN( ) and XEND( ) functions, in a static assembler lib. However I am unclear how (or if) the stack gets restored to the original xbegin calling state, given an xabort originating at some other stack level (higher or lower). In other words, is the dynamic stack context (including interrupts effects) managed and rolled back as just another part of the transaction? This assembler approach is needed for a VC++ 2010 build

Default property value in React component using TypeScript

由 安稳与你 提交于 2019-11-27 10:20:56
I can't figure out how to set default property values for my components using Typescript. This is the source code: class PageState { } export class PageProps { foo: string = "bar"; } export class PageComponent extends React.Component<PageProps, PageState> { public render(): JSX.Element { return ( <span>Hello, world</span> ); } } And when I try to use the component like this: ReactDOM.render(<PageComponent />, document.getElementById("page")); I get an error saying property foo is missing. I want to use the default value. I've also tried to use static defaultProps = ... inside the component,
