//! SPARC Target Backend — Sun/Oracle SPARC v8/v9 RISC architecture.
//!
//! Complete register information, instruction set metadata, instruction
//! selection, MC encoding, and assembly printer for the SPARC architecture
//! family, covering both 32-bit SPARC v8 and 64-bit SPARC v9.
//!
//! Clean-room behavioral reconstruction from the SPARC Architecture Manual
//! Version 8 and Version 9, the SPARC ABI Supplement, and the SPARC
//! Compliance Definition. Zero LLVM source code consultation.
//!
//! Architecture coverage:
//! - SPARC v8: 32-bit integer, FPU, windowed register file
//! - SPARC v9: 64-bit integer extensions, VIS
//! - 3 instruction formats: Format 1 (CALL), Format 2 (SETHI/Branches),
//!   Format 3 (all arithmetic/logical/memory)
