Introduction
MOSA is an open source software project that natively executes .NET applications within a virtual hypervisor or on bare metal hardware!
The MOSA project consists of:
Compiler - a high quality, multi-threaded, cross-platform, optimizing .NET compiler
Kernel - a small kernel operating system
Device Drivers Framework - a modular, device drivers framework and device drivers
Debugger - QEMU-based debugger
Current Status
The target platforms are:
32-bit x86
64-bit x86 (x64; in development)
32-bit ARMv8+ (in early development)
64-bit ARMv8+ (in early development)
The MOSA compiler supports most object and non-object oriented code, including but not limited to:
Generic Code (e.g. List<T>)
Delegates (static and non-static) and with optional parameters
Exception Handling (try, finally, and catch code blocks)
The MOSA compiler seeks to provide high quality code generation using the following optimizations (non-exhaustive):
Constant Folding and Propagation
Strength Reduction optimization
Dead Code Elimination
Single Static Assignment (SSA)
Global Value Numbering / Common Subexpression Elimination
Sparse Conditional Constant Propagation
Inlined Expansion
Loop-Invariant Code Motion
Null Check Elimination
Devirtualization
Block Reordering
Greedy Register Allocation
For an exhaustive list, see Compiler optimizations which also gives a description of each of these optimizations.
