llvm-native-core 0.1.6

//! X86/X86-64 Target Backend — complete instruction selection, register
//! allocation, calling convention, frame lowering, MC encoding/decoding,
//! and assembly printer for the x86 architecture family.
//! Phase 10 — LLVM.TARGET.X86.1 Court.
//!
//! Clean-room behavioral reconstruction from:
//! - Intel® 64 and IA-32 Architectures Software Developer's Manual
//!   (volumes 1, 2A, 2B, 2C, 2D, 3A, 3B, 3C, 3D)
//! - AMD64 Architecture Programmer's Manual (volumes 1-5)
//! - System V Application Binary Interface: AMD64 Architecture Processor
//!   Supplement (with LP64 and ILP32 programming models)
//! - Microsoft x64 Software Conventions
//! - X86-64 ELF ABI Specifications
//! - cdecl/stdcall/fastcall/thiscall/vectorcall calling conventions
//!
//! Zero LLVM source code consultation. All behavior reconstructed from
//! published specifications and black-box oracle interrogation.
//!
//! Architecture coverage:
//! - X86-64 (AMD64, Intel 64, x64): full 64-bit mode
//! - IA-32 (i386, i486, i586, i686): full 32-bit protected mode
//! - X86-16 (8086, 80286): real mode (limited support)
//! - Instruction set extensions: MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1,
//!   SSE4.2, AVX, AVX2, AVX-512 (F/CD/ER/PF/BW/DQ/VL), FMA, BMI, BMI2,
//!   ADX, SHA, SGX, CET, etc.
//! - Operating modes: 16-bit, 32-bit, 64-bit
//! - Addressing modes: 16-bit, 32-bit, 64-bit with all ModR/M and SIB
//!   combinations

// Staged module declarations — modules are added as their implementation
// files are created. Currently active:

// Phase 10: register info, subtarget, target machine, calling convention,
