EFICS Compiler v1.2.0 STABLE (EFI C-Sharp)

EFICS is an ultra-lightweight, zero-dependency compiler designed to transform high-level C# code into native UEFI (.efi) executables for x64 architecture.

Built entirely in C# 5.0, this tool allows developers to write "Bare Metal" code with the elegance of C# syntax, bypassing the need for the .NET Runtime or any operating system.

Key Features (v1.2.0 Stable)

• Ultra-Minimalist Footprint: The compiler executable is only 8.5 KB, optimized for extreme efficiency.
• Zero-Padding Engine: Generated .efi binaries are "pure" and contain only the necessary code and data, with no unnecessary bloat.
• Master Instruction Set (110+): Full support for x64 arithmetic, advanced logic, stack manipulation, and extended registers (R8 through R15).
• Flow Control: Enhanced support for conditional jumps (Je, Jne, Jg, Jl) and labels for complex loops and logic.
• Integrated UEFI Protocols: Native support for GOP (Graphics), MOUSE (Pointer), and SFS (Simple File System).
• Unicode String Engine: Handles UTF-16 encoding automatically for UEFI.Print calls.
• Zero-Dependency Build: Can be compiled using the legacy csc.exe included in Windows 10/11.

Why EFICS?

EFICS bridges the gap between high-level logic and low-level hardware access, enabling:

• Custom Bootloaders: Load kernels and hand over CPU control.
• Recovery Utilities: Create graphical tools and disk repair systems that run before any OS.
• OS Development: Explore hardware interrupts and memory mapping using a modern, clean language.

Quick Start

1. Compile the compiler:

   C:\Windows\Microsoft.NET\Framework64\v4.0.30319\csc.exe EficsCompiler.cs
   

Create your script (boot.cs):

using EFICS; using EFICS_variables;

class MyOS { static void Main() { UEFI.Print("EFICS v1.2.0 Loaded!"); CPU.Halt(); } }

Generate the EFI binary: bash EficsCompiler.exe boot.cs
