- Introduces F32 and F64 types and Float operand variant to the IR. - Implements floating-point binary operations (FAdd, FSub, FMul, FDiv, FRem, FCmp) and FNeg unary op. - Updates IR printer, validator, and builder to handle the new floating-point functionality. - Extends the constant folding pass to evaluate floating-point expressions at compile time. - Enhances x86_64 backend with XMM register support and floating-point codegen. - Implements a fixed-point iteration pass for register type resolution to correctly allocate GPR vs XMM registers. - Updates the linear scan allocator to manage multiple register classes (GPR, XMM). - Adds System V ABI compliant handling for floating-point function arguments and return values. - Includes comprehensive tests for IR validation, constant folding, and assembly generation.
