Change Log

v0.4.1 (2021-05-14)

• numerous additions and improvements to SPIR-V frontend:
  • int8, in16, int64
  • null constant initializers for structs and matrices
  • OpArrayLength, OpCopyMemory, OpInBoundsAccessChain, OpLogicalXxxEqual
  • outer product
  • fix struct size alignment
  • initialize built-ins with default values

v0.4 (2021-04-29)

• development release for wgpu-0.8
• API:
  • expressions are explicitly emitted with Statement::Emit
  • entry points have inputs in arguments and outputs in the result type
  • input/output storage classes are gone, but push_constant is added
  • Interpolation is moved into Binding::Location variant
  • real pointer semantics with required Expression::Load
  • TypeInner::ValuePointer is added
  • image query expressions are added
  • new Statement::ImageStore
  • all function calls are Statement::Call
  • GlobalUse is moved out into processing
  • Header is removed
  • entry points are an array instead of a map
  • new Swizzle and Splat expressions
  • interpolation qualifiers are extended and required
  • struct member layout is based on the byte offsets
• Infrastructure:
  • control flow uniformity analysis
  • texture-sampler combination gathering
  • CallGraph processor is moved out into glsl backend
  • Interface is removed, instead the analysis produces ModuleInfo with all the derived info
  • validation of statement tree, expressions, and constants
  • code linting is more strict for matches
• new GraphViz dot backend for pretty visualization of the IR
• Metal support for inlined samplers
• convert example is transformed into the default binary target named naga
• lots of frontend and backend fixes
