Mission Statement

This project aims at making the Valgrind tool suite available on Microsoft Windows. The project founder believes that is it technically possible to run Valgrind natively on Windows, and that a coordinated, collaborative effort by open source developers will eventually deliver a stable and production-ready release.

The project targets current x86-based 32 bit and 64 bit Windows versions that are NT kernel-based (Windows XP and newer). Valgrind needs to support 3 environments on those platforms:

• WIN32 : 32 bit applications running on a 32 bit Windows
• WOW64 : 32 bit applications running in a 32 bit compatibility subsystem on a 64 bit Windows
• WIN64 : 64 bit applications running on a 64 bit Windows

Help wanted
