Module writer

Modules

• workgroup_mem_init 🔒
  Initializing workgroup variables is more tricky for Metal because we have to deal with atomics at the type-level (which don’t have a copy constructor).

Structs

• ArraySizeMember 🔒
  Wrapper for generating struct _mslBufferSizes member names for runtime-sized array lengths.
• ClampedLod 🔒
  Wrapper for identifier names for clamped level-of-detail values
• ExpressionContext 🔒
• StatementContext 🔒
• TexelAddress 🔒
  Values needed to select a particular texel for ImageLoad and ImageStore.
• TypeContext 🔒
• TypedGlobalVariable 🔒
• Writer

Enums

• FunctionOrigin 🔒
• LevelOfDetail 🔒
  A level of detail argument.

Constants

• ARGUMENT_BUFFER_WRAPPER_STRUCT 🔒
  For some reason, Metal does not let you have metal::texture<..>* as a buffer argument. However, if you put that texture inside a struct, everything is totally fine. This baffles me to no end.
• ATOMIC_COMP_EXCH_FUNCTION 🔒
• ATOMIC_REFERENCE 🔒
• CLAMPED_LOD_LOAD_PREFIX 🔒
  Prefix for cached clamped level-of-detail values for ImageLoad expressions.
• FREXP_FUNCTION 🔒
• MODF_FUNCTION 🔒
• NAMESPACE 🔒
• RAY_QUERY_FIELD_INTERSECTION 🔒
• RAY_QUERY_FIELD_INTERSECTOR 🔒
• RAY_QUERY_FIELD_READY 🔒
• RAY_QUERY_FUN_MAP_INTERSECTION 🔒
• RAY_QUERY_TYPE 🔒
• RT_NAMESPACE 🔒
• WRAPPED_ARRAY_FIELD 🔒

Functions

• needs_array_length 🔒
• put_numeric_type 🔒
  Write the Metal name for a Naga numeric type: scalar, vector, or matrix.
• scalar_is_int 🔒
• separate 🔒
• should_pack_struct_member 🔒

Type Aliases

• BackendResult 🔒
  Shorthand result used internally by the backend
