Memory<T> API documentation and samples

This document describes the APIs of Memory<T>, IMemoryOwner<T>, and MemoryManager<T> and their relationships to each other.

See also the Memory<T> usage guidelines document for background information.

First, a brief summary of the basic types

• Memory<T> is the basic type that represents a contiguous buffer. This type is a struct, which means that developers cannot subclass it and override the implementation. The basic implementation of the type is aware of contigious memory buffers backed by T[] and System.String (in the case of ReadOnlyMemory<char>).

PE/COFF Specification Addendum

Deterministic PE/COFF File

PE/COFF file is deterministic if it is produced by a tool that guarantees that the entire content of the file is based solely on documented inputs given to the tool (such as source files, resource files, compiler options, etc.) rather than ambient environment variables (such as the current time, the operating system, the bitness of the process running the tool, etc.). The content of the file can be reproduced exactly (bit for bit) given the same inputs.

The value of field TimeDateStamp in COFF File Header of a deterministic PE/COFF file does not indicate the date and time when the file was produced and should not be interpreted that way. Instead the value of the field is derived from a hash of the file content. The algorithm used to calculate this value is an implementation detail of the tool that produced the file.

RyuJIT

The Open Source Just in Time Compiler for .NET

WHEN & WHERE

This tutorial was given at PLDI 2016. The content is available here.

ABSTRACT

This tutorial will present an introduction to RyuJIT (rē-yü-jit), an industry leading, high performance Just-in-Time compiler that supports the Microsoft .NET ecosystem. RyuJIT is also used to deliver world class performance on in house 1st party services like Office 365, Bing, and Exchange through innovative design and focus on business results. RyuJIT is shipping in the .NET 4.6 product and is now open source as part of CoreCLR.

An overview of the architecture of RyuJIT will be presented, including the internal representation (IR) and compilation phases with a focus on key design and imple
