In Win32, each process has an associated address space. Portions of address space can be reserved, mapped (or "committed"), or unmapped ("freed") using the functions VirtualAlloc and VirtualFree. (In addition, NT allows one process to allocate memory in another process). File objects can be memory-mapped...

I always like to start with litle history then answer the WHY question. Phoenix History Several years ago the Visual C++ was cranking out compiler backends, doing platform retargeting (x64, IA64) for example was a painful process, and a small group in the Microsoft VC team decided that it would be worth...

Plugin is one topic that I will cover in my TechEd SEA presentation. A "plug-in" means a user-written module that will be executed by backend compiler (C2), or a Phoenix-based analysis tool. Suppose we build a plug-in, called OurPlugIn.dll for C2.exe. Then, with the appropriate command-line switches...

PREfast is analysis tool to identify defects in C/C++ source codes. It uses our existing build structure and works by intercepting native compiler. Intraprocedural analysis in PREfast identifies defects in the C/C++ source files. Users commonly run PREfast over a section of code, view results, make fixes...

Phoenix Phases Phoenix manages its processing using pipeline-like architecture. Each execution steps in this pipeline called phases and Phoenix already has built-in pipeline that can be listed using -dumpphaselist C2 switch. Phases are stored as an ordered list and are executed sequentially. Inter-phase...

Phoenix supports modular compiler phase design. It allows us to select phases that we want invoked including core processing phases in Phoenix framework. In addition, Phoenix supports the ability to customize the phases invoked via a managed DLL plug-in. The DLL phase plug-in can manipulate the phase...

Conservative GC like Boehm-Demers-Weiser can be used as a GC replacement for C malloc or C++ new. You can allocate memory basically as you normally would, without explicitly deallocating memory that is no longer useful. The collector is also used by a number of programming language implementations that...

Most of LOB developers don’t have a clear understanding what is inside DLL/EXE even though they have done it with managed or native compilers. One job of compilers is to produce PE/COFF for your OBJ/assemblies. If you know what's inside your OBJ/assembly, you'll find that you've become a better...

M2 maybe the most difficult tasks C++ developers face. Problems like dangling pointers and memory leak will become big risk for your shipped applications. M2 is the art and the process of coordinating and controlling the use of memory (RAM or ROM). M2 can be divided into three areas: - M2 hardware (MMUs...
