vyre-driver-wgpu 0.6.5

//! Integration contracts for VYRE C parser covering Linux-GNU declaration,
//! type, and preprocessor syntax contracts.
//!
//! Coverage:
//!   * typedef shadowing (including by __auto_type)
//!   * enum/tag scopes and forward declarations
//!   * GNU __attribute__ on structs and function-pointer typedefs
//!   * __auto_type declarations
//!   * typeof / typeof_unqual in declarators
//!   * _Alignas and __attribute__((aligned(...)))
//!   * nested designated initializers with range designators
//!   * bit-fields (named, unnamed, zero-width, with attributes)
//!   * flexible array members
//!   * complex function pointers (signal-like)
//!   * abstract declarators in casts
//!   * statement expressions containing inline asm in initializers
//!   * macro-shaped declarations (call-like macro syntax at top level)
//!   * nested conditional preprocessing (#if / #ifdef / #else / #elif / #endif)
//!
//! Every test asserts parser/VAST/PG contracts and GPU/CPU parity where
//! applicable. A missing GPU adapter is a configuration failure.
